Saying that Apple is suing Samsung over rectangles with rounded corners is a simplification, but it certainly defines the most prominent aspects of their claims of infringement. I came up with an experiment to determine whether Apple should have an exclusive claim to this shape. A rule for the construction of this shape is that it cannot have much added to it beyond what I specify in my instructions for its construction.
Here is what the shape should look when finished.
- Create a rectangular prism with the dimensions 80x40x5.
- With a 90º circular arc of radius 2, cut off the corners of the largest facet by aligning the arc's endpoints with the edges and have the convex side point to each corners' respective vertex.
- Create a rectangle with the dimensions 60x36 centered on the surface of one of the largest facets.
