Keywords: power tools market status application development trend
Power tool products have been widely used because they can save manpower and improve efficiency. Now they have played an indispensable role in our daily production and life. However, due to the innovation of technology, it is still in constant development. Now, through the simple investigation and understanding of power tool products, the application status and development trend are analyzed.
1. Analysis and application of current status of electric products
Power tool products are products with a certain technological content, and because of its great applicability, it also has certain technical added value. The power tool product integrates a series of industrial technologies such as material control, material forming, motor, chemical technology, etc., so its industrial chain can be driven to a wide range. Power tool products have different status quo in different stages of development. In developed countries, because industrial industries use a large number of large-scale machines that are automatically controlled, the demand for power tools as auxiliary labor is small, and more Family life or application in individual small-scale production.
According to survey results, 60% of electric tools are used in households in developed countries in Europe and America. In developing countries like China, this proportion will be smaller, and it also shows that the potential market for household electric tool products in China is very broad. Due to the low pollution of power tools, China is strongly supportive of this production industry at this stage. Today, China is ranked first in the exporting countries of power tools and twice as much as Germany, the second exporter. China has become a big country in the production and export of power tools.
At present, the industry is optimistic about the development of the power tool industry, and believes it has good prospects. On the one hand, because the power tools are cheap, the method of use is simple and easy to learn, and the application is convenient, it is very popular among consumers; on the other hand, the power tool product is a consumable product, so the demand for it is always kept. The high state; moreover, the power tool has an extremely wide range of applications, due to the limitations of its individual product application functions, the demand for the type of power tool products for life or production is also quite large, in order to cope with different uses.
Power tools can be divided into two categories according to their use: industrial and household. According to their processing objects, they can be divided into eight categories: metal cutting tools, sanding tools, woodworking tools, construction tools, railway mine tools, assembly tools, agricultural and pastoral tools, and other tools. In fact, the application range of power tools covers all parts of human production and life. As an extremely important tool for production and life, the market demand for power tools is quite large.
2. Ergonomic design of electric products
The final service target of all products is human, so the design of power tool products must follow the principle of letting users have a better experience during use. Therefore, the design and manufacture of power tool products are generally guided by ergonomics.
2.1 Power tools must meet the needs of users
The handle of the power tool that directly contacts the user for a long time is an extremely important part. Its design must fully consider the posture of the user when working, the length of the working time, the direction and method of the force during work, and then combine the above points. Design.
(1) Tools such as electric drills that are smaller, lighter and need to work in the horizontal direction generally design the handle as a pistol type. It is convenient for the user to adjust the working posture, and can also use the longer effective arm of the type of handle to withstand the strong reaction torque generated during the work, reduce the labor intensity of the user, and reduce the damage to the user's body.
(2) If it is a relatively large tool that is subjected to a large reaction force when working, it is generally necessary to use a T-handle or a D-shaped handle to facilitate user control and operation. Moreover, the handle cannot select a material that is too rigid, and a material that can be deformed in a small range should be selected, so that the user can obtain a certain cushion when receiving the force.
(3) The handle design of the power tool must be tighter and more natural when the user holds it. Therefore, the groove is designed with reference to the shape of the index finger and the thumb, and fits the palm of the user to avoid the sliding range of the tool during work. Too big.
(4) Some tools are too strong due to the application of their applications, and they also design auxiliary handles to help users better control tools and apply more force. Some auxiliary handles also allow the user to design a certain range of rotation for the left or right scorpion, so that the user can adjust the more comfortable use according to his own wishes.
(5) For the convenience of use, the switches of small electric tools such as hair dryers are usually designed close to the handle, which is convenient for the user to control with one hand and saves a certain working time.
2.2 Consider the safety of power tools
In the process of using a power tool, the effect produced by the power tool directly affects the human body. Therefore, in order to protect the human body from being damaged or as little as possible, the safety of the power tool must be fully considered in design. Sex.
(1) Some tools, such as cutters, can produce debris or debris when used. These small scraps can splash around and cause harm to the human body. Therefore, when designing this type of tool, it is necessary to fully consider the direction in which the debris flies out, to ensure that they do not directly harm the human body or are insufficient to cause injury when touching the user's body. This is usually done by adding baffles or by changing the spout.
(2) Sometimes, the user may need to work at heights. Because the different postures that the user may use at work may cause changes in the center of gravity, the design of the power tool must take into account the balance of the center of gravity, not too biased. At the working end or the handle end. It should be as easy as possible for the user to maintain balance when using.
(3) The power tool generates a certain vibration when it is used. This vibration is transmitted to a part of the user's body through the handle that is in direct contact with the user or affects the whole body. Every part of the human body has its own fixed vibration frequency. If the frequency of vibration during the use of the power tool is similar to the fixed frequency of a certain part of the human body, it may cause damage to the human body due to resonance, such as joint deformation, joints. Wear, bone fracture, etc. Therefore, when designing a power tool, it is necessary to fully combine the application range of the tool and the vibration frequency when working with a large number of experimental testers. There are two standards in the world for design reference. They are "Mechanical Vibration - Evaluation and Guide for Human Hand Contact Vibration" and "Handheld Portable Power Tools - Guide to Handle Vibration". Power tools should be referenced during design. These two guidelines prevent the product from harming the user due to resonance. Generally, it is necessary to improve the design and improve the level of processing technology. Such as improving the precision of the transmission part such as gears, changing the quality of the tool, etc. to change the vibration frequency of the power tool during operation. (4) Tools with motor in the working part generally generate noise when used, and the presence of noise can easily affect the user's emotions, causing the user to have negative emotions such as irritability and anxiety, which is not conducive to work. Moreover, if the intensity of the noise is too large, it may even cause permanent damage to the user's hearing. Therefore, the power tool should be designed to take into account the impact of the working environment and take certain measures to reduce the noise generated during work. For example, the shape of the design is designed to reduce noise, provide sound insulation or sound absorbing devices, provide earplugs or other protective devices.
3. The design of electric products
Power tools must also be designed to take into account the user's general preferences. Making small changes and changes in color and shape may be more responsive to the public. Sometimes a small protrusion or arc, a few different combinations of the same color block will affect the overall visual effect of the tool, and the aesthetically pleasing tools will feel comfortable when used.
3.1 Color matching when designing power tools.
Power tools need to be designed with the user's age, gender, personality characteristics and other factors in mind. Therefore, it is necessary to design different colors according to different types of work.
(1) Household life tools such as vacuum cleaners and hair dryers are generally used as women, and the ambient atmosphere is softer. Therefore, the choice of color generally requires a warm color or a brighter coating.
(2) The users of power tools used in higher-intensity work are generally male, and the working environment is generally harsh. Therefore, the choice of color generally selects a cool color system, or the darker color makes the tool more resistant to dirt.
(3) Sometimes it is necessary to emphasize a certain part on the tool, such as the handle of the handle, the switch, the function button area, the components that cannot be directly touched by the hand, etc., and the color that is not in harmony with the whole machine will be used. Prominent effect.
Power tools are designed to take into account the different working environments and the nature of the work, with selective changes to the appearance. For example, if some jobs require users to maintain a high degree of enthusiasm for a long time, they will choose more large curved surfaces, fewer straight lines, outwardly expanding curved surfaces, etc. Some work has high precision, Design more compact planes, smaller buttons, compact housings, etc.; and some tools are designed to be special shapes due to the particularity of the group.
4. Development trend of electric products
Today, China's demand for electric products is increasing year by year. In Europe and the United States, households have a large market share in the use and consumption of power tools; in China, this proportion is small, which means that there is still a large potential market in China. Moreover, more and more other countries have taken a fancy to this part of China's market. In recent years, they have come to China to invest and build many factories that produce electric tools. Therefore, this industry can be developed at a high speed for the present and foreseeable future.
Because power tools are closely integrated with the development of technology, its replacement is very fast, its functions will become more comprehensive, and the scope of coverage will become more and more extensive. Since the need for high efficiency in production and life will not end, the market demand for power tools will not decrease. Moreover, the technology of power tools is constantly innovating, and because of its combination with a wide range of science and technology, it has always been able to get new blood, and more and more development directions. For example, the combination of electronic technology and power tools enables power tools to develop in an intelligent direction, expanding the range of applications of power tools and increasing their functions. There is also the development of environmentally-friendly power tools, which conforms to the trend of the times and conforms to the theme of today's world. This aspect of research is sure to be strongly supported by the state. In addition, the current wireless charging technology is constantly evolving. In the near future, the combination of power tools and wireless charging technology will be further improved, and its convenience and adaptability to the working environment will be further improved.
Therefore, the power tools should be developed in the direction of intelligence, green, and simplification.
In short, power tools have a very broad market. Due to the wide range of operations, power tools have a very large demand. With the development of science and technology, the design of power tools will be more user-friendly, simple to use, more convenient to carry, and more green, and will be more and more popular with users.
