Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different programs are set in the welding device for different battery modules, then welding accuracy is maintained, but program development amount increases and cutting, pulling and model changing efficiency decreases
Solution Approach 1:
The patent implements a universal welding program that can handle multiple battery module types through automatic recognition. The system uses vision sensors to identify the specific module type and automatically adjusts welding parameters and paths without requiring manual program changes, making the welding device multi-functional across different product variants
Solution Approach 2:
The system dynamically changes welding parameters (such as welding path coordinates, speed, and other process parameters) based on the recognized battery module type. By storing parameter sets for different module types and automatically selecting the appropriate parameters, the system maintains welding accuracy while eliminating the need for separate programs for each module type
