Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cooling pipelines are frequently bent for setting, then the cooling device can adapt to different layouts, but the flow resistance increases and space is occupied
Solution Approach 1:
The cooling pipeline is divided into multiple detachable segments that can be independently positioned and connected. Each segment can be separately adjusted to fit different spatial requirements, while the straight configuration of each segment minimizes flow resistance. The segmentation allows the system to adapt to various layouts without requiring continuous bending of the pipeline.
Solution Approach 2:
The cooling pipeline segments are designed to nest within each other or within the battery pack structure when not in use. This nesting capability allows the pipeline to occupy minimal space while maintaining the ability to extend and configure into different layouts as needed, reducing both space occupation and flow resistance from unnecessary bends.
2Adaptability or versatility
If cooling pipelines are frequently bent for setting, then the cooling device can adapt to different layouts, but a large space is occupied
Solution Approach 1:
The cooling pipeline is divided into multiple detachable segments that can be independently positioned and connected. Each segment can be separately adjusted to fit different spatial requirements, while the straight configuration of each segment minimizes flow resistance. The segmentation allows the system to adapt to various layouts without requiring continuous bending of the pipeline.
Solution Approach 2:
The pipeline segments are designed to utilize three-dimensional space efficiently, allowing vertical and diagonal arrangements in addition to horizontal positioning. This multi-dimensional configuration capability enables the cooling system to adapt to complex battery pack layouts while maintaining compact dimensions and minimizing overall space occupation.
3Ease of manufacture
If joint structures are used for cooling pipelines, then the cooling device can be assembled, but the flow rate and flow speed of cooling medium are affected
Solution Approach 1:
The pipeline segments are designed with integrated connection features that merge the joint structure into the pipeline wall itself, rather than adding separate external fittings. This integration ensures smooth internal flow passages without protrusions or constrictions at connection points, maintaining high flow speed while preserving assembly capability. The merging of connection and pipeline functions eliminates flow disturbances that would otherwise occur at joint locations.
