Improving Public Bathrooms
DES243 Assignment 2 - public bathrooms By Harry Bushell
Find out as much as you can and describe the ideas you have about public bathrooms. What sorts of problems did you identify? What sorts of solutions can you imagine? How has this changed your thoughts about this most mundane of human facilities?
Personal experience - Throughout my lifetime, I’ve used a fair share of different toilets. From high-tech automatic toilets in Dubai, to toilets with hoses instead of toilet paper in Malaysia, each houses its own positives and negatives. For example, the highly automated design I experienced in Dubai was extremely easy to navigate, and required minimal effort to proceed through the bathroom experience. With automated doors, automated looks, automatic taps and soap dispensers, the bathroom appealed to a large majority of people, as automated equipment allows a variety of people to be able to use the bathroom, regardless of motor ability or strength. However, the bathroom would only flush once you unlocked the door with a big button and left. This proposes a big potential problem. If the toilet is blocked, or requires two flushes to flush correctly, then this will be unable to happen, the only way to flush the toilet is to enter and leave again. This means that if a blockage occurs, or a second flush is required, the next person using the bathroom will have an unpleasant experience due to the toilet not flushing correctly. This could be solved by simply allowing the user to control the flush. Through the simple incorporation of a big, easy to press flush button, this problem is solved. On the other end of the spectrum, the public toilet I used in Malaysia left a lot to be desired. The distinct lack of toilet paper, which instead was replaced by a hose-type instrument, resulted in quite an uncomfortable experience. After some brief research, I’ve discovered that these hose things are known as bidets. These bidets are definitely a different take on the toilet experience, and while I see the reasoning behind their use, I feel that toilet paper should’ve been available for use as well.
How this has changed my thoughts - Both of these experiences, as well as research conducted online, have changed my approach to this assignment already, and have made me think about parts of bathrooms that I would normally take for granted (toilet paper for example). They also made me think about ways that these could be changed, improved, or downright removed. Furthermore, through research, I discovered the reasons for things in bathrooms that I was overwise oblivious to, like showers for example, which after research I found are present for people that would otherwise not have a hygienic place to shower. Despite this, I think this could be further improved, and is partially an aspect that I'll approach in the later part of this assignment.
From my research, as well as my experiences, I concluded on the two aspects chosen below.
Choose two aspects that you think you could improve on. Use speculative design to tease out some ideas. Be creative and don’t just choose something simple – this is an opportunity to show your skill, work through some designs and be creative.
Draw or write about the two aspects mentioned above, and how these will work for people with a myriad of disabilities.
For each of these two aspects, draw a diagram or write at least three paragraphs as a design guide for people constructing a public bathroom that could be useful when building or refurbishing. You should point out aspects that they need to be aware of that they might not think of otherwise.
The toilet seat is a crucial aspect of public toilets, or more to the point all toilets. As they stand, the average toilet seat in an average public toilet offers a simple seating experience. Depending on the design, they can be either end of the comfort spectrum, with some being plastic and shaped partially anatomically, and others being metal and shaped ovally. The plastic shaped seats offer a better experience in terms of comfort and affordability to the less abled, but still are far from ideal when it comes to different heights, angles, further comfort, accessibility etc. With this in mind, I believe that I can improve on certain aspects in regards to toilet seats, and through using a speculative lens as suggested, I can overcome the limits of what we know now to design something that offers a greater solution than if I used a more realistic design approach.
Ideas for toilet seat iterations (speculative)
Toilet seats that change height after the user is scanned on entrance to ensure the correct height is in place
Pros: Offers comfortable heights for all, proposing an easier use of public toilets for people with disabilities or with physical difficulties. Scanning technology is mostly available.
Cons: having to be scanned could take up valuable time. Expensive.
A toilet seat that adjusts height, angle, and size through verbal commands. On entrance a person can voice their needs i.e their disability and the toilet will adjust accordingly
Pros: Offers a completely comfortable and personal experience for people that have required changes.
Cons: Verbal tech might not be able to recognize commands correctly and wouldn't work for people that are mute.
A self cleaning toilet seat
Pros: clean toilet seats to ensure a basic comfortable experience. Less high tech than other ideas so easier to incorporate.
Cons: Sustainability and creates a lot of waste.
A toilet seat that incorporates a bidet that is angled to allow hand-free cleaning. Built in dryer as well
Pros: Offers easy cleaning that doesn’t require the use of hands, meaning limited arm and hand movement won’t affect the users ability to clean.
Cons: Angle would have to be correct along with other things, would need something incorporated to allow it to stop hands free.
Personal toilet seats that when plugged into the outside of the public toilets create a custom interior toilet that’s personalized to the users needs.
Pros: Creates a completely custom toilet seat experience allowing the heights and angles to appeal to less able people that would need different toilet heights.
Cons: Requires the ability to plug something in, maybe a card scan would work better as it requires less motor ability. Both also could use up valuable time.
Collapsible toilet seats that expand out (Tony Stark suitcase) and are placed on compatible toilets.
Pros: Creates a completely custom toilet seat experience allowing the heights and angles to appeal to less able people that would need different toilet heights.
Cons: time taken for it to expand out, and having to use motor skills to place the seat onto the compatible toilet.
Chosen idea: Personal toilet seats that when plugged into the outside of public toilets create a custom interior toilet that’s personalized to the users needs.
With my chosen idea, I believe, through multiple iterations, it can result in a near perfect toilet seat experience. Through offering personalization with each user and the fact that this is speculative, the toilet seat can practically take any shape or size in order to meet the needs of its user. The information received for how the toilet seat will appear comes through personalized cards, that are scanned quickly on entrance to allow the bathroom to know which seat to place in the room. This information will be programmed onto the cards using a website or app, and if needed, can be programmed by doctors and physicians for less able users. These toilet seats can be raised higher or lower to appeal to the needs of the user. For example, users with less or weaker motor skills would have higher seats to ensure that there is less difficulty raising and lowering themselves. Furthermore, bars could fold out from the seat to further assist raising and lowering. Along with this, I think incorporating the bidet and built-in dryer would further the toilet seat experience, and would be a welcome customization option when programming the user’s card. This would mean lesser abled users could hygienically use the toilet without worrying about arm and hand difficulties. Adding to this, another option would allow the toilet to raise and lower with a button push or sensor, to allow users that need it to go from standing, to sitting, to standing again all while supported by the seat. For wheelchair users, the toilet seat could be customized with bars so that users could lift themselves on and off. Or, if needed, the seat could slide underneath the wheelchair, and by supporting the legs of the user, slowly slide them off their chair and onto the toilet. With these iterations, and other customizations that I haven’t thought of or listed here yet, I believe that this toilet seat will offer as close to a perfect toilet seat experience as possible. Despite this, there are still obvious flaws. The scanning and transition process of the seat customizing itself for the user will take up valuable time if viewed from a realistic lens, and in the heat of the moment this could be detrimental. However, speculatively this could all happen extremely quickly and use up minimal time. Furthermore, people potentially unable to scan cards or possessing extremely minimal motor skills would still struggle with the use of these toilets. With this in mind, I believe that the perfect public toilet, in particular the toilet seat, is realistically highly unlikely to be achieved due to the sheer amount of customization required for different people to share an equally successful experience.
Entrance - If available, the entrance must be on a flat surface or with a supporting ramp to allow access to all. The scanner on the door must be accessible from all heights, and will be accessed when the user's card is scanned. If applying to already built toilets, ensure that the sensor still can be accessed from all heights. This is a crucial part of the installation of this system, as if the scanner is not accessible by all, then the aim of the toilet seat iteration will not be met.
Wiring - Once the scanner has been installed, the wiring from the scanner must be able to reach the toilet station area, where the customized toilets are stored. Once this wiring is installed, ensure that it works with a test scanner card. Ensure the wiring is out of sight and hidden so it cannot be tampered with or damaged.
Toilet - PRE BUILT: If using a pre built toilet, ensure that the plumbing and pipe work is protected to ensure minimal construction is needed. Once the toilet and plumbing is protected, begin the installation of the toilet seat customizer. By removing .3m wide by 1m long either side of the toilet base, ensure that no piping is damaged. Once the area has been marked out and removed, dig .5m down to create an area either side of the toilet base for the toilet seat customizer tools. Once the area is complete, install and wire the toilet seat customizers.
Toilet - NEW BUILD: Remove the area required to install a basic toilet set up, piping included. Once removed, ensure the new toilet seats are installed onto the compatible toilet. The area removal on either side of this build is still required if a compatible toilet is used, once again a .3m wide by 1m long area. This area will be the same .5m depth. Once the areas are constructed, ensure the newly built toilet is in position and functional, and then install the nanotech toilet seat wiring and design either side of the toilet.
The aspect of drying has always annoyed me when using public toilets, and with the research on the presence of showers in public toilets, I think that a good dryer is more important than ever for a successful public toilet. Default hand dryers in public toilets often do little to actually dry your hands, and do nothing to dry people after the use of a shower. With this I think there is huge room for improvement in the drying aspect of public toilets. The options available now are commonly; paper towels (produce a lot of waste and require capable motor skills), Reusable hand towels (often broken machines and need repairing often, plus require capable hand use) and hand dryers (useless for drying after a shower and often very average at drying hands, however don't require any grip strength to use or hand maneuverability). With these pre-existing options in mind, and from the pros and cons listed, I think hand dryers offer the most potential in terms of creating an accessible drying experience for all. Thanks to the speculative approach suggested, I believe that I can create something that would vastly improve the drying aspect of public toilets.
Ideas for hand dryer iterations (speculative)
A dryer that can also be used for the showers, i.e a drying capsule that is wheelchair friendly. Maybe even a capsule that is both the shower and dryer
Pros: offers full body drying for all abilities, as long as they can be maneuvered into the dryers range.
Cons: would use a lot of energy and space
A dryer that changes size when sensing what's in front of it, can be used for just hands or the entire body
Pros: Offers a full range of drying, body and hands. Only uses required power due to changing size. Offers drying to all, as long as they can move into the dryer.
Cons: Energy consumption. A room that can change size by scanning something is quite high tech for a bathroom. Expensive
A towel generator that creates towels that are then recycled into a new towel each use
Pros: Depending on the size of towel generated, could be used for the entire body or just hands. Recycling the towels means minimal waste created.
Cons: Would require maintenance with frequent recycling of towels. Energy consumption. Means that motor skills are required to grab and use the towel.
Robot dryers that lock onto parts of your body that need drying (think little orb floaty thingies that zoom around the room)
Pros: offer a full range of drying, don’t require any interaction meaning less able people can still dry properly.
Cons: Programming and expense to create and manufacture something like this.
Chosen idea: Robot dryers that lock onto parts of your body that need drying
With these ideas, I believe that I have approached the aspect of drying in different ways, and figured out multiple different ways that the aspect can be improved. With this, I like my robot dryer idea the most, as it is the most speculative and fun idea in my opinion. Robot dryers that lock onto parts of your body that need drying offer what I believe to be the most intriguing and potentially effective solution to improving the aspect of public toilet dryers. Through the incorporation of multiple technologies like moisture sensors, voice activation, solar power, and further developments I haven’t listed or thought of yet, these robot dryers could offer a complete, efficient and accessible drying experience. Appearing like orbs, these robots will feature high power warm air dryers, and float around using miniature fans to allow themselves to maneuver around the user to dry all aspects of their body if they've used a shower, or move around the users hands if they need drying. The dryers will have sensors present that are linked to the doors to ensure that they cannot leave the bathroom. The robots will sense what needs drying through scanning the user and using moisture sensors to pick up wet areas. If required, the robots could also be controlled by voice commands if more drying is needed or if you want the robots to stop. The robots will begin their drying process once the shower has been turned on and off, or when the tap has been turned on and off. When not in use, the robots will store themselves in a charging docket powered by solar panels on the roof of the public toilet. Thanks to the maneuverability of these robots, they offer drying for all people, no matter their potential restrictions. Furthermore, they propose a drying option to those that have used public toilet showers and don’t possess a towel or adequate drying equipment. Furthermore, if the shower is used by someone who lacks the arm strength or maneuverability to dry themselves could still be dried with no effort other than just standing still.
Charging docket: The charging docket measures 1m by .55m by .25m. The docket must be installed below the roof and at the opposite side of the door, at a safe height so it cannot be considered a hazard. The installation is near the roof to minimize the required wiring to attach the docket to the solar panel positioned on the opposite side of the roof to act as a power source for the dryers. If in a location where there is minimal sun, another power source is required. Once installed, ensure that the dryers are securely attached to the docket, and test the wiring to the taps and shower to ensure that the dryers detach and reattach successfully.
Door and theft prevention: Ensure that the sensor is installed above and below the door. Test these sensors with the dryers to ensure that they work and so that the dryers cannot leave the bathroom unless deactivated (which will require a special key). Ensure that the sensors are placed in positions which pose no threat as a trip or potential hazard in any way. Ensure that they will not make entrance to the bathroom any harder, and are mostly discreet so they cannot be damaged easily.
Taps and Shower requirements: Ensure that the tap and shower are functional, and that when turned on and off the water stops relatively quickly. Once the tap and shower are working properly, attach a sensor to the shower and tap that will stop the dryers locking onto their left over water drops when using its moisture sensors. Make sure that the wiring that reads when the tap and shower are turned on and off is discrete and offers no hazards in any way. Then, wire them to the charging docket and test. The dryers should, with the sensors attached, be released when the tap or shower are turned off, and will return to their charging station when the user leaves the bathroom and the door senses itself being closed.
Prepare one 'hero image' that shows a key aspect of one of the designs you have come up with that you think is particularly innovative. This can either be your own drawing, or a montage of images you have found that illustrate your design idea. These will be compiled into a set of slides to be shared with everyone in the class. You may use a few words (eg. 10 or so) to point out key details.
Keep a record of the key moments in your learning journey, and describe in particular the path you have taken, the inspirational references you have found, etc.
Information gathering phase - Although my experiences have shaped my thoughts on what should be improved and what aspects I want to focus on, I thought it would be smart to ask for others' experiences and what others would want to change. With this in mind, I asked my sister and my mother what they would change about public toilets. My sister mentioned the lack of hygiene and overall uncleanliness of public toilets. We bounced a few ideas off each other and came to the conclusion of making the public toilet into what's practically a massive dishwasher. We decided that the room could have a water source that stems from the floor and roof, and shoot clean soapy water all around the public toilet to clean it, and then through the same shooters, fire warm air in order to dry out the toilet. We both enjoyed the speculative nature of this concept, however I decided against pursuing it further due to the consequences that present themselves with a concept like this. For example, massive amounts of water would be used in this process, and it would also take up valuable time when the cleaning process took place. We decided that it would have to clean itself once a day, and preferably at an hour of least popularity in order to reduce the amount of potential accidents where the toilet is unable to be used due to cleaning. Despite this, I quite like a few of the ideas we created, and will try to incorporate them in later parts of this assignment. Next, I spoke to mum to see what she would change. Mum mentioned that the floors always seem to be sticky, and the toilet seats are often uncomfortable or dirty. Due to the sticky floors mostly being due to cleaning chemicals used, and the fact we already discussed cleaning, Mum and I decided to look into how to change toilet seats, and I ended up using some of these ideas for my first aspect.
Design and aspects phase - This was by far my favourite phase of this assignment. Thanks to the speculative approach suggested, I practically had free reign of what to design. However, due to my personality and design thinking, I tried to create designs that, while still speculative, had mostly realistic or possible features. In this phase, I took big inspiration from the lecture done on cyborgs, as well as my love for superheroes like Iron Man and Batman. With this in mind, and the inspiration from Iron Man in particular, my design for aspect 1 was influenced heavily by the scene in Iron Man 2 when Tony Stark's suit folds out of his briefcase and onto his body. With this idea, of a smaller package folding into something shaped perfectly through nanotech and little grooves and squares, I thought I could design something similar to provide a perfectly shaped toilet seat. Although my design isn’t perfect, as there are only a select amount of squares, I still think it's a cool concept, and the idea of these squares flipping over each other and building something new through technology is very cool in my opinion.
For my second aspect, I took a lot of inspiration from a video game called Destiny, where a small hovering robot is a useful companion throughout the game. With this design and concept in mind, I ideated my final idea for aspect 2. Considering the abilities of this companion, I thought it would be cool to dull such an interesting robot design into something very basic like a hand dryer. So, that’s what I did. I went for a sleeker rounded design for the drying orbs to make them appear more friendly, and went for a sleek black colour to ensure they show dirt less. I incorporated cool detail colours like the robot shown below, with the most interesting being the aqua blue used for this robot's eye. I used the same colour for a detail on my design, as I think it creates a very futuristic look through minimal detail.
Hero Image process - This was, despite the lack of quality in my image, the hardest part of this assignment. I still don’t really understand what a hero image is and how they were wanted to appear, so I went for a pretty basic display of what I think the orb could appear like if created from objects that already exist. With the movement rotor created from those hover sensor toy things, and the drying fan just being an air heater. I found a very intriguing orb robot that floated around the international space station, and thought it showed the key design of the robot dryers well. I shifted its colouring to black and added the cool aqua details to the robot, as well as shifting it’s eye colour to match. Then I used an image of a public toilet for the background. While it's obviously not a very polished image, I was unsure on what else I should create, so I kept it as it was. Although it’s not executed to a very professional look, I quite like how it turned out, and I think the robot looks cool, friendly, and helpful, which is exactly what I was going for. I used a few labels to point out key aspects of this design to ensure it fit the hero image criteria given.
