Abstract: Aiming at the requirements on the ability of police drones to perform tasks, this paper proposes an innovative design method for police drones based on grey relational analysis of quality function development (GQFD) and theory of inventive problem solving (TRIZ). GQFD transforms the mission requirements of the police drone into the performance requirements of the police drone and the corresponding key technologies and their importance, thereby understanding the design goals by the importance of key technologies. The paper also applies TRIZ theory to analyze key problem conflict types in design goals, and uses standard engineering parameters and the invention principle which settles conflicts to obtain a specific design and implementation plan. In practice, the integrated method can reduce the human-factor interference in the design under the condition of lack of information and a small amount of sample analysis, and make up for the deficiency of a single innovative design theory, displaying the advantages of being able to quickly and accurately find the design direction and obtain a feasible design solution. The feasibility of the GQFD-TRIZ integration method was demonstrated through the implementation of the innovative design of the police drone in the urban management environment.
