Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional battery structure is used, then the device complexity is low, but the structural strength is poor and the battery is susceptible to damage from collisions
Solution Approach 1:
The reinforcing structure is segmented into first reinforcing structures extending in the second direction and second reinforcing structures extending in the first direction, forming a fishbone-like pattern. This segmentation allows the reinforcing structure to distribute stress more effectively across the battery cells while maintaining a manageable complexity level.
Solution Approach 2:
The reinforcing structure introduces additional dimensional support by having first reinforcing structures extend in the second direction and second reinforcing structures extend in the first direction, creating a two-dimensional reinforcement pattern that significantly enhances structural strength without proportionally increasing complexity.
2Reliability
If the reinforcing structure is added to enhance structural strength, then the stability and service life are improved, but the device complexity increases
Solution Approach 1:
The first and second reinforcing structures are merged into an integrated fishbone-like reinforcing structure that provides comprehensive support. This merging approach enhances reliability by creating a unified support system while avoiding the complexity of multiple separate reinforcement components.
Solution Approach 2:
The reinforcing structure serves multiple functions: it provides structural support, distributes collision forces, and enhances overall battery stability. This multi-functionality improves reliability without requiring additional separate components, thereby limiting the increase in device complexity.
3Stability of the object's composition
If the first reinforcing structures and battery rows are stacked, then the structural stability is significantly improved, but the manufacturing complexity increases
Solution Approach 1:
The first and second reinforcing structures are pre-configured in a fishbone-like pattern before assembly with the battery cells. This preliminary configuration ensures proper alignment and stacking positions, making the subsequent assembly process more straightforward and reducing manufacturing complexity despite the enhanced structural stability.
