Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wired connections are used to connect multiple battery packs in parallel, then reliable electrical contact is achieved, but device complexity and maintenance requirements increase
Solution Approach 1:
The patent combines mechanical coupling and electrical connection into a single integrated interface. The magnetic coupling mechanism simultaneously provides mechanical attachment and electrical contact through integrated contact pads, eliminating the need for separate wiring harnesses and connectors. This merging reduces device complexity while maintaining reliable electrical contact between battery packs.
Solution Approach 2:
The patent replaces traditional mechanical wired connections with a magnetic coupling system. The magnetic attraction force provides both the mechanical bonding to hold battery packs together and the pressure necessary to maintain reliable electrical contact between contact pads, eliminating complex mechanical wiring systems.
2Reliability
If traditional wired connections are used for parallel battery pack connection, then stable power transmission is achieved, but weight and complexity increase
Solution Approach 1:
The patent replaces heavy traditional wired connections with a lightweight magnetic coupling system. The magnetic fields provide both mechanical attachment and electrical contact without requiring heavy gauge wires, connector housings, and mounting hardware, significantly reducing the overall weight of the battery pack system while maintaining stable power transmission.
Solution Approach 2:
The integration of mechanical coupling and electrical connection into a single magnetic interface eliminates redundant components such as separate wiring harnesses, connector shells, and mounting brackets. This consolidation reduces the total material mass and system weight while maintaining reliable power transmission capabilities.
3Strength
If additional mounting hardware is used for parallel battery pack connection, then secure mechanical coupling is achieved, but ease of operation decreases
Solution Approach 1:
The patent replaces complex mechanical mounting hardware (screws, bolts, clips, and brackets) with a magnetic coupling system. The magnetic attraction force provides secure mechanical coupling that is automatically engaged when battery packs are brought into proximity, eliminating the need for manual assembly and disassembly of multiple fastening components, thereby significantly improving ease of operation.
Solution Approach 2:
The magnetic coupling system is self-actuating and requires no manual intervention for engagement or disengagement. When battery packs are brought close together, the magnetic force automatically pulls them into coupled position and maintains the connection. To disconnect, users simply pull the packs apart, and the magnetic force releases automatically, providing a self-service connection system that is both strong and easy to operate.
