Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery cells are connected in a stacked manner to improve capacity, then the battery capacity increases, but the risk of tearing at the joint of battery cells increases
Solution Approach 1:
A supporting member is introduced as an intermediary component between the electrode output parts of stacked battery cells. This supporting member provides mechanical support to the joints, distributing stress and preventing tearing while maintaining the electrical connection. The supporting member acts as a mediator that allows the stacked configuration to maintain both high capacity and reliable connections.
Solution Approach 2:
The supporting member is pre-installed in the accommodating space before or during the assembly of battery cells in the stacked configuration. This beforehand cushioning provides protective support to the electrode output parts, preventing tearing from occurring in advance by distributing mechanical stress before it can concentrate at the joints.
2Reliability
If a supporting member is added to support electrode output parts, then the stability of electrical connection improves, but the weight of the battery increases
Solution Approach 1:
The supporting member is designed using thin-walled or film-like structures that provide sufficient mechanical support while minimizing material usage and weight. These thin-film supporting structures can effectively distribute stress and prevent tearing at electrode joints without adding significant weight to the battery system.
Solution Approach 2:
The supporting member is strategically placed only at critical locations where electrode output parts require support, rather than providing universal reinforcement throughout the entire battery structure. This localized support approach maintains electrical connection stability at critical joints while minimizing overall weight addition.
3Device complexity
If the supporting member is integrated with the packaging structure, then the device complexity reduces, but the adaptability for different battery cell configurations decreases
Solution Approach 1:
The supporting member is designed with universal characteristics that allow it to function effectively across different battery cell configurations and packaging structures. The supporting member can be adapted to various stacked arrangements of battery cells while maintaining its core function of preventing tearing at electrode joints, thus achieving both reduced complexity and maintained adaptability.
Solution Approach 2:
The supporting member incorporates dynamic design elements that allow it to adapt to different configuration requirements. The supporting structure can be adjusted or reconfigured to accommodate different battery cell arrangements, maintaining versatility while keeping the overall structure integrated and relatively simple.
