Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple battery units are connected using separate connection components, then electrical connection and insulation are achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The holder integrates multiple functions into a single component: it provides mechanical support for battery units, electrical insulation through its material properties, and structural framework for connection. The electrode plates are integrated directly into the holder structure, eliminating separate connection components while maintaining reliable electrical connections between battery units.
Solution Approach 2:
The holder serves multiple purposes simultaneously: it acts as a mechanical support structure, an electrical insulator, a mounting framework for electrode plates, and a protective enclosure. This multi-functionality reduces the total number of components needed while ensuring reliable electrical connection and insulation.
2Quantity of substance
If battery module capacity is increased by adding more components, then capacity extension is achieved, but manufacturing cost and device complexity increase
Solution Approach 1:
The battery module is divided into standardized battery units that can be independently manufactured and then assembled in various configurations. Each unit includes battery cells, a holder, and integrated electrode plates. This segmentation allows capacity to be scaled by simply adding or removing standard units without increasing complexity or manufacturing cost per unit.
Solution Approach 2:
The standardized holder design with integrated electrode plates can accommodate different numbers and arrangements of battery units. The same basic holder structure serves universal purposes across all capacity configurations, eliminating the need for custom components for each capacity level and reducing manufacturing costs.
3Reliability
If traditional connection methods are used, then electrical connection is achieved, but manufacturing efficiency decreases due to additional assembly steps
Solution Approach 1:
The electrode plates are integrated directly into the holder structure during holder manufacturing, rather than being assembled separately. This merging of components eliminates multiple assembly steps in the manufacturing process while ensuring reliable electrical connections between battery units through the pre-integrated plate structure.
