The problem with making devices that "look futuristic" is that they're often inspired by things in movies or TV shows set in the future, where it really is just about the look. Function is not deeply important, because even a live action movie with practical effects is an illusory construct. Things work because the story says they work. That isn't how it happens in the real world.
Make the thing work. Then, add lovely filigrees and decorations and things that can make it aesthetically pleasing without impinging upon the functionality. (Also, usability is quintessential to functionality.) Or, do what is sometimes the case with certain cars and things, and embrace that the functionality of a device can be beautiful in itself.
Either way, stop trying to make everything look like the bridge of the Enterprise-D. That's a beautiful design for a work of fiction, but I'm not sure it's the best way to make a starship in real life.
