Phantom work : design iteration timing in new product development
… market increases, companies often compress their design iteration cycle times in an effort to develop products more quickly. In many cases, design cycles may overlap creating situations where learning opportunities (e.g. through testing) are missed and/or ignored. More perversely, compressing …

The development of a minimum weight design algorithm using fully stressed design iteration
… method for obtaining a minimum weight structural design, called an optimum design. The optimum design iteration is based on a sequence of fully stressed designs, each intermediate design possessing a distinct set of allowable stresses that force the desirable design changes to occur. The test for …

Enabling New Functionally Embedded Mechanical Systems Via Cutting, Folding, and 3D Printing
Traditional design tools and fabrication methods implicitly prevent mechanical engineers from encapsulating full functionalities such as mobility, transformation, sensing and actuation in the early design concept prototyping stage. Therefore, designers are forced to design, fabricate and assemble …
