The systematic, non-experiential prescriptions of classical design methodology continue to have a strong presence in large segments of design research and education while another segment sees domain experience and consequent intuition and creativity as being key to successful design. In this paper the two approaches are outlined and the empirical research literature in human behaviour is employed to discern discrepancies and potential weaknesses. Results show that gaining experience in a domain intrinsically changes how one designs, which the classical methodology does not account for. For example, only designers with tactile and visual domain experience can abstract functions per the dictates of the classical (non-experiential) methodology, which means that they cannot have used the methodology to learn basic design in the first place – or did so only with great difficulty. This and other conflicts pose problems for the education of engineering design students, and to fathom their extent this paper surveys engineering design textbooks offered in Canada and the U. S.; all of the books are found to embrace the classical methodology. If they are to remain involved in preparing students for entry into industry then some aspects of their contained classical methodology must be supplanted by experiential approaches to design educatio

Decomposition Of Functions

The engineering design methodology of Pahl and Beitz is good in the detailed stages, but needs enhancement in the early stages of conceptualizing and embodiment-in-principle. The concept of ‘functions’ has been enhanced by Hubka and colleagues. A ‘functional basis’ (Hirtz et al) has improved the definitions of ‘flows’ and ‘functions’, their work does not go far enough to provide a basis for conceptualizing. ‘Affordances’ (Maier and Fadel) are covered by full use of systematic conceptualizing of design engineering solutions. The Pahl-Beitz model and method of ‘decomposition of functions’, ‘physics’, and components is contrasted with the Hubka models of a transformation system, TrfS, its constituents, structures, properties life cycle, etc., and their use as method for design engineering by searching for alternative embodiments at each of these levels of abstraction. These steps are illustrated in (to date) 21 case examples published between 1976 and 2012, several of them in the CEEA conferences and their predecessors.

Capstone Design

In the teaching of engineering design, it may be common to use design methodology (DM), as documented in several textbooks, in the course delivery.  However, considerable drawbacks could be observed in our case when DM is taken as the major guidance for a capstone design course. We argue that DM tends to prescribe some context-free methods and procedures, which cannot be easily applied by students to their capstone design projects. At the same time, we observe that students need support to characterize a design problem, integrate technical knowledge in design activities and verify design ideas. These aspects require analytical and critical thinking, where DM may not be particularly helpful for students. In the five-year journey of deemphasizing DM in a capstone design course, we have explored and examined various pedagogical approaches such as online modules, design labs and peer evaluations.  Without the teaching of DM, the pedagogical strategy needs to be carefully planned to deliver specific learning in engineering design.

The Relationship

This article presents an overview of discussions in the philosophy of technology on epistemological relations between science and technology, illustrating that often several mutually entangled issues are at stake. The focus is on conceptual and ideological issues concerning the relationship between scientific and technological knowledge. It argues that a widely accepted hierarchy between science and technology, which echoes classic conceptions of epistêmê and technê, engendered the need of emancipating technology from science, thus shifting focus to epistemic aspects of engineering design and design methodology at the cost of in-depth philosophical analysis of the role of scientific research in the engineering sciences. Consequently, the majority of current literature on this topic in the philosophy of technology presents technology as almost completely divided from and independent of science, thereby losing sight of the epistemic relations between contemporary scientific practices and technology.
