Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If simple connection methods are used between battery packs, then the device complexity is reduced and ease of manufacture is improved, but the connection reliability deteriorates and the connection becomes easy to get loose
Solution Approach 1:
The connection structure is divided into multiple functional components: connecting components (screws/bolts) for fixation, connecting parts (grooves/bulges) for positioning and insertion, and support parts for load bearing. This segmentation allows each component to perform its specific function optimally while maintaining overall connection reliability through a modular assembly process that remains manufacturable.
Solution Approach 2:
The connecting parts are pre-formed with grooves and bulges that guide the insertion process, and support parts are pre-positioned to bear loads before final tightening. This preliminary action ensures proper alignment and reduces the complexity of the assembly process while guaranteeing reliable connection from the outset.
2Device complexity
If simple connection methods are used between battery packs, then the device complexity is reduced, but the connection stability deteriorates and safety is compromised
Solution Approach 1:
Multiple connection functions are merged into an integrated structure: the connecting parts provide both positioning (through groove-bulge fit) and insertion guidance, while the connecting components provide both fixation and load transfer. The support parts are integrated with the connecting structure to provide continuous support. This merging achieves high connection stability without proportionally increasing device complexity.
Solution Approach 2:
The connection structure employs composite design combining different material properties and connection mechanisms: metallic connecting components for strength, molded connecting parts for precision fitting, and support structures for load distribution. This composite approach achieves superior connection stability while maintaining reasonable device complexity.
3Ease of operation
If simple connection methods are used between battery packs, then the device complexity is reduced and ease of operation is improved, but the connection becomes loose and safety is reduced
Solution Approach 1:
The groove-bulge connecting parts are pre-formed to guide automatic alignment and insertion during operation. The support parts are pre-positioned to bear loads before final tightening. This preliminary action ensures proper alignment and reduces the complexity of the assembly process while guaranteeing reliable connection from the outset.
4Device complexity
If the connecting structure does not bear shear forces, then the device complexity is reduced, but the connection reliability deteriorates under load
Solution Approach 1:
The connecting components (screws/bolts) are designed to simultaneously bear shear forces from lateral loads and tensile forces from vertical loads. The support parts are integrated to work together with the connecting components, distributing and sharing the mechanical loads. This merging of load-bearing functions into the connection structure achieves high strength without proportionally increasing device complexity.
