HAIR TRAP

HairTrap is a device that traps and removes hair from hands and shower surfaces and allows for no-touch disposal. This was a whitespace service design project.

I designed and ran an experiment to test the effectiveness of bristles at picking up hair based on bristle: spacing, size, and material stiffness.

​

  1.  Optimal spacing between bristles is 2mm.

  2.  Rigid material overall performed higher.

  3.  Cone-shaped bristles are best at picking up hair from hands.

  4. Cylindrical-shaped bristles are best at picking up hair from tiled walls.

From the data I concluded that:

Resulting design:

Solution

The final prototype exhibits bristles that are optimal for both grabbing hair from hands (cone shape) and grabbing hair from tiled walls (cylinder shape). The clear acrylic housing contains a spring mechanism that allows the user to "push" hair off or the bristles and straight into the trash. The user will never have to touch dirty, wet hair again!
