Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a harness with insulation wires is used to electrically connect energy storage cells to balancing circuit terminals, then electrical connections can be established, but erroneous wiring, short circuits due to covering damage, or disconnection occur during wiring work
Solution Approach 1:
The patent extracts and eliminates the harness component from the wiring system. Instead of using separate insulation wires to connect energy storage cells to balancing circuits, the invention integrates the electrical connection function directly into the energy storage cell structure through terminal boards with exposed terminal portions, thereby removing the source of wiring errors and disconnections
Solution Approach 2:
The patent merges the electrical connection function with the energy storage cell structure. The terminal board is integrated into each energy storage cell assembly, combining the cell holder and electrical terminal functions into a single unified structure, eliminating the need for separate harness wiring
2Ease of manufacture
If electrodes of multiple energy storage cells are connected to multiple bus bars with individual harness wires coupled to corresponding bus bars and balancing circuits, then electrical connections are established, but a lot of manpower and time are demanded and additional wiring processing is required
Solution Approach 1:
The patent segments the wiring function into integrated terminal boards that are part of each energy storage cell assembly. Each terminal board contains the necessary electrical terminals and connection structures, allowing independent assembly and connection without requiring centralized harness wiring operations
Solution Approach 2:
The terminal boards are pre-integrated into the energy storage cell assemblies during cell manufacturing, with electrical terminals and connection structures prepared in advance. This preliminary integration eliminates the need for time-consuming on-site wiring operations and reduces assembly complexity
