Abstract: To realize function and principle innovative design of mechanical products, a new process model of function and principle solution was proposed based on Theory of Inventive Problem Solving (TRIZ) and Functional Analysis (FA). In this model, abstraction of general function, confirmation of principle solution to general function and function decomposition were included in FA. Confirmation of principle solution to general function was the premise of function decomposition. To provide a dependable pattern for function decomposition, a new function analysis method was put forward based on the generalized process function along with the introduction of the input constraint function; and its five-decomposition-steps were also presented. To provide powerful support for innovative design tools in principle solution, some TRIZ tools in the model were imbedded, such as Su-field Analysis, Scientific Effects, and Contradiction Solution Principles so as to boost up the innovation of principle solution. As a case study, an innovative design of paint-bottling machine has been achieved with application of the proposed model.
