Assess Design Alternatives With Axiomatic Design

Al Hamilton, of Axiomatic Design Solutions, wrote a good article on how Axiomatic Design can be used to evaluate multiple design alternatives.

Here is an excerpt from the article:


Four Design Spaces of Axiomatic Design

Axiomatic design breaks the design process into four domains, shown in Figure 1.  The customer domain can be thought of as the voice of the customer (VOC).

  1. The functional domain is initially populated by mapping the VOC into independent measurable functions. High-level functions are driven by the customer; lower-level functions are driven by design choices. Every function must be measurable.
  2. The physical domain is the domain of physics, chemistry, math and algorithms.
  3. The process domain is where the specifics of how the design parameters identified in the physical domain will be implemented.

Dr. Mike Shipulski, director of engineering at Hypertherm, a manufacturer of plasma cutting systems, has made extensive use of axiomatic design. Shipulski observes, “By first defining the functions we are to achieve, we align our problem solving on the right areas and broaden possible design opportunities. With axiomatic design, we have a framework for avoiding problems that are often detected only during system-level testing.”
