Add-on Brush

In order to make cleaning easier for customers, I created a multifunctional brush that was inspired by Joseph Joseph's design. After thoughtful market research, I discovered existing brushes only have single functions, so customers have to buy additional brushes to clean different dinnerware. For example, a decanter needs a long sponged tool, while a porcelain mug might need a short sponged head. Consequently, I designed a tool with replaceable heads and adjustable handle length. The brush can be adjusted to three lengths by rotating the handle. Users can have three choices of brush heads, including flat, round, and sponge brush heads.

What I learned

I have learned how to apply detailed market research to identify the design opportunities, and user centered development to lead deceptions on function, form, materials and manufacturing.
