Application of the Theory of Inventive Problem Solving (TRIZ) to Creative Engineering Design for the Motor Cooling System of an Electric Vehicle

This paper aims to apply the tool of the Theory of Inventive Problem Solving (TRIZ) to the creative engineering design and discussion of the motor cooling system of the electric vehicle, and the permanent magnet motor cooling problem is used as the principal axis of the creative engineering design of this study. During the process of this study, the TRIZ tool is used to solve the possible cooling problems and energy efficiency issues caused by a running motor, and is intended to improve cooling efficiency and effectively avoid the problem of the accumulation of thermal energy, which causes constant increasing temperature and further causes the motor and surrounding mechanisms to be damaged. This paper uses the design and discussion of function analysis, with 76 standard solutions, 39 engineering parameters, and 40 invention principles in the TRIZ tool to design and discuss the possibility of improving cooling efficiency and creative design, which is expected to provide help and reference direction for the research and development of electric vehicles in the future.
