The first page of the UPTO listing for the patent awarded to my collaborator Jay Beckwith and I for this project. It is a first for both of us, in spite of many years of design experience.

Pipe Topper Concept 1 : One of many concepts for holding vertical pipes together in the Gymboree system. Even though they are not refined sketches or renderings, I put a lot of these in this portfolio, because they demonstrate my design flexibility and give a view to the depth of my problem-solving skills.

Pipe Topper Concept 5
Pipe Topper Concept 6. The funny thing about this potion of the project is that the client chose not to change anything from their existing design. That's just part of the game with design - even great ideas may not surface as products in the end.
Rail Attachment Concept 1 (Again, I included a series of these to express design flexibility and creativity) It is my beleif that the designer should explore as many solutions to a design challenge as possible in order to arrive at the best.

Concept for a Rotationally-Molded Box for part of the Gymboree system. I designed these so that all of the sides could be molded parallel. In this case, I consided the structure of the mold as a means of achieving this. In the end, the client chose to use a furniture-grade plywood design for these components.
