The core of the technological product innovation is in the conceptual design, which needs to be addressed in a convergent way to supplement lack of technological trajectory, lack of resources for testing and laboratories, and encourage networking of researchers. That is the case of countries with less technological development where the scarcity of resources is obvious. In this article it is proposed a methodology for conceptual design, based on the use of test results from existing data, and the matrix of contradictions of the inventive methodology TRIZ. This methodology is then applied to the conceptual design of an adsorption refrigeration system using exhaust gas of automotive vehicles. Affording a new conceptual design.
