Abstract
This paper describes a methodology for systematizing knowledge concerning natural laws for engineering design. It is assumed that natural law can be represented by constraint and behavior, and that relations among natural laws can be described by using a scheme of constraint and behavior. The methodology of this study is a systematization focusing on the constraint of natural laws and relations among natural laws. After some discussion, it was found that natural laws could be systematized into a natural law description model, and a relational knowledge of natural laws could be systematized into a natural law relational model, a dictionary and an operation algorithm of natural laws. As a result of this study, it is confirmed, through some examples, that the assumptions made in this study are valid and that this approach is feasible for engineering design.
