Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional battery packs use multiple structural parts (housing, battery module, cell support, busbar, collection plate, screws) to assemble and fix cells, then the battery pack can be assembled and fixed, but the assembly process becomes complex and cost increases
Solution Approach 1:
The patent merges multiple separate structural components (cell support, busbar, collection plate, and fixing structure) into a single integrated housing. The housing directly holds the cylindrical cells and provides both mechanical support and electrical connection functions, eliminating the need for separate assembly steps and reducing the total number of parts.
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it serves as the structural container, the cell support, the electrical connection component (through integrated busbars and collection plates), and the fixing mechanism (through built-in fixing members). This multi-functionality reduces the number of specialized parts needed.
2Quantity of substance
If traditional battery packs reserve mounting space for multiple structural parts, then the battery module can be assembled, but the space utilization rate decreases and overall product size increases
Solution Approach 1:
By combining multiple functional components into the housing, the patent eliminates the need for separate mounting spaces for cell supports, busbars, and fixing mechanisms. The cells are directly received in the housing, maximizing the use of available internal volume for active energy storage components.
Solution Approach 2:
The patent implements a nested structure where the cells are directly received within the housing cavities, and the electrical connection components are integrated within the same housing space. This nesting approach allows components to occupy overlapping or adjacent spaces efficiently, reducing the overall envelope volume.
