Systematic Functional Design for Sustainable Innovation

Functional design is an important method for problem-solving and high-level innovation, and function innovation is the front end of functional design. Sustainable function innovation is a practical and innovative way to solve the issue of sustainability. Based on the concept of front-end prevention, functional design and sustainable design are integrated. The key enabling technologies for sustainable function innovation (function evolution, function combination and function failure) are studied, and then systematic functional design process is built from function innovation angle. Integrated systematic functional design, the innovative process model for sustainable innovation is introduced. A innovative design example of continuous source for CdTe deposition on a glass sheet substrate demonstrates the proposed model and theory is feasible.
