Product Improvement

When brainstorming, Sonia and I thought of the problem of tangled earbuds.   We wanted a way to store them without them getting tangled or in the way, so we came up with the following design.  

It is a new case that will store earbuds by allowing you to wrap the cord around two knobs and close over the cord.  A plastic piece covers the cord and snaps shut.

When changing design, one must consider the problem, buyer, convenience, and appearance.  It is important to document your brainstorming so you don't lose your ideas.  Sketching your ideas allows you to convey your ideas to others.  It also will help you prove that you thought of the idea on a certain date in case someone else tries to say they did.  It was effective for Sonia and I to share our engineering notebooks when presenting.
