Design of Multi-task Scene Image Acquisition System in a Spacecraft Based on TRIZ

Theory of inventive problem solving (TRIZ) is an innovative theoretical system that includes identifying and analyzing technical problems, and obtaining innovative solutions and algorithms for technical problems. This theory can effectively guide engineering designers to design innovative products in engineering practice, and solve practical engineering problems effectively and efficiently. This paper focuses on the demand for image acquisition of multiple key task scenes during the flight of the spacecraft. Based on TRIZ, the technical problem is analyzed and restated. The technical contradictions brought by the new multi-task scene image acquisition system to implement new function are determined. By the conflict solving principle (one of TRIZ tools), several innovative design directions to solve this design problem are anchored. And then the design scheme of the new system is obtained by designing in detail in the directions mentioned before. This scheme has well met practical demand and achieved satisfactory results. It is proven that TRIZ can effectively guide innovative design and research in the field of aerospace machinery.
