Project Objective

To create a solar-powered household product.



Rounds of research:

  • Solar energy
  • Questionnaire
  • Observations
  • In-depth interview
  • Market and competition

The resulting target market for this project is described in the persona to the right.

This project focused on ways to assist with cleaning the toilet because it was identified as a particularly unpleasant chore.



The toilet sanitizer developed into a concept with two separate pieces: one solar-charged power source and one ultraviolet sanitizing bulb.

Since the power source had to sit in the window, garden animals and plants inspired the shape of that part in later iterations.


Final Result

The final form was inspired by a lady bug.


  • Solar battery charger
  • Battery
  • Ultraviolet light bulb toilet clip

The CAD models were done in Solidworks.
