Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mounting structure passes through the first through hole and abuts against the third wall in the gap, then the structural performance is improved, but the space utilization rate may be reduced due to the gap occupation
Solution Approach 1:
The mounting structure utilizes the gap dimension between the third wall and first wall to achieve abutment and structural support, effectively using the Z-direction space rather than occupying XY-plane space. This dimensional approach resolves the contradiction by converting a potential space-wasting gap into a functional mounting region.
Solution Approach 2:
The gap region, which might be considered wasted space, is transformed into a functional zone with specific mounting capabilities. The mounting structure is locally adapted to utilize this gap space for abutment against the third wall, giving local functional quality to what would otherwise be empty space.
2Stability of the object's composition
If the adapter sleeve extends along the second direction to form the first extension portion, then the mounting stability is improved, but the space utilization rate is reduced due to the extension occupying internal space
Solution Approach 1:
The adapter sleeve extends along the second direction (perpendicular to the first direction) to provide mounting stability, utilizing the vertical dimension rather than consuming horizontal space. This allows the battery to maintain stability while preserving the horizontal space for battery cell arrangement.
Solution Approach 2:
The mounting structure is segmented into multiple directional components: the adapter sleeve body providing horizontal connection and the extension portion providing vertical support. This segmentation allows each part to optimize its function in its specific direction without compromising overall space utilization.
3Strength
If the first cross beam is disposed between the first wall and the second wall, then the structural integrity is improved, but the internal space is reduced due to the cross beam occupation
Solution Approach 1:
The first cross beam is designed as a thin-walled structural element that provides sufficient structural integrity while minimizing space occupation. The thin-walled design allows the cross beam to maintain structural strength without consuming excessive internal volume, resolving the contradiction between structural integrity and space utilization.
Solution Approach 2:
The cross beam structure utilizes the thickness dimension minimally while providing strength in the primary load-bearing directions. By optimizing the beam's dimensional proportions, structural integrity is achieved with minimal impact on the internal space available for battery cells.
