This paper evaluates the Pugh Controlled Convergence method and its relationship to recent developments in design theory. Computer executable models are proposed simulating a team of people involved in iterated cycles of evaluation, ideation, and investigation. The models suggest that: (1) convergence of the set of design concepts is facilitated by the(More)

This paper explores the role of one-at-a-time experimentation in parameter design of engineering systems. The focus is on degree of improvement achieved rather than on efficiency in estimating model parameters. The performance of adaptive one-at-a-time plans is compared with the performance of orthogonal arrays through computer simulations based on data(More)
The purpose of this research was to improve body powered, voluntary closing (VC) prosthetic prehension. A prototype prehensor with variable mechanical advantage was fabricated and tested. The device operates at low mechanical advantage during sizing of an object to reduce cable excursion requirements. It shifts to high mechanical advantage during gripping(More)

The editors of this journal have offered an opportunity to reply to Dr. Hazelrigg's letter in depth. Indeed, with its numerous points of critique of the paper ''The Pugh Controlled Convergence method'' (Frey et al. 2009) stated so strongly, the letter demands a detailed rebuttal. We provide a response to the specific points discussed in the letter as well(More)
