2 Computational Solid Mechanics and Design Lab. Axiomatic design Axiomatic design is a design methodology that was proposed and popularized by Professor Suh of MIT (currently President of KAIST). It is a design framework that is feasible on all design disciplines. The Independence Axiom, The Information Axiom An axiom is a statement accepted without proof as an underlying assumption of a formal mathematical theory. It cannot be proved. If a counter example is found for an axiom, the axiom becomes obsolete. Geometry, Laws in Physics, Thermodynamic principles
3 Computational Solid Mechanics and Design Lab. Axiom Examples of axioms in Geometry: Points and lines are names for the elements of two (distinct) sets. Incidence is a relationship that may (or may not) hold between a particular point and a particular line. The followings are examples of axioms: 1) For every two points, there exists a line incident with both points. 2) For every two points, there is no more than one line incident with both points. 3) There exist at least two points incident with each line. 4) There exist at least three points. Not all points are incident with the same line. Examples of axioms in Physics: 1) Newton’s law: F = ma 2) Thermodynamic principles 3) ……

4 Computational Solid Mechanics and Design Lab. Axiomatic Design The design process is a continual interplay between what designers want to achieve and how they achieve it. The objective of axiomatic design is to “establish a science base for design and to improve design activities by providing the designer with a theoretical foundation based on logical and rational thought processes and tools” [Suh (2000)].
5 Computational Solid Mechanics and Design Lab. Axiomatic Design • basic assumption there exists a fundamental set of principles which determines good design practice. • distinction natural science : real, definitive design (artificial domain) : arbitrary, subjective • reason intelligent computer analysis for the most optimum design solution.

6 Computational Solid Mechanics and Design Lab. What is design? Design involves a continuous interplay between what we want to achieve and how we want to achieve it . Objective of design is stated in the functional domain . Physical solution is generated in the physical domain . Design procedure involves interlinking these two
