Optimization Design of Underwater Vehicle Based on TRIZ Theory

With the progress of science and technology, the technology of underwater robots has gradually matured, equipped with cameras, sonar systems and robotic arms, and has been widely used in underwater resource detection, fishery breeding and scientific research. Traditional underwater robots are generally large in size and low in flexibility. The spiral propulsion method often produces eddy currents, which makes the stability of swimming poor and has a certain impact on the surrounding environment. In order to solve these problems, this paper analyzes the existing problems based on TRIZ theory, uses TRIZ tools to obtain design schemes, proposes innovative methods, and optimizes the design of underwater robots. Explore the future development direction of the product through the nine-screen analysis method; through the functional analysis of the system, find functional defects; using technical contradictions, physical contradictions, object field analysis and other tools to solve the selected key problems, find the contradiction matrix, apply the separation method to seek solutions, and finally get the underwater vehicle design optimization scheme.
