There’s a sketching technique that I think is really beneficial to those who are at a loss for ideas. It’s something I learned a long time ago when I learned to draw: the scribble method :). Basically, it consists of scribbling on a page. You don’t even have to look at the sheet of paper. You don’t even have to use your dominant hand. Using marker, scribble a little doodle on a sheet of paper.
Once you have your doodle, start to highlight the lines you really like. Maybe there’s a strong line in the center of your page. Maybe there are two parallel lines that could become a handle or car’s spoiler. I don’t know.
Start to add a little bit of detail…does your handle need a grip? Add a few notches to create a place for your fingers. The possibilities are endless. These are sketches done for controllers and pencil sharpeners using the scribble method. (Of course color was added to create a little bit of a better idea of what everything was)
