Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If vibration-generating unit is used to align unit cells, then unit cells can be aligned after insertion, but the major axes and minor axes of unit cells cannot be properly aligned and sophisticated conveyor belt is required
Solution Approach 1:
The guide members are positioned beforehand to define the correct alignment path for unit cells before they are inserted into the stacking jig. The guide members pre-establish the alignment geometry, so that when unit cells are inserted, they are automatically guided into proper alignment without requiring complex post-insertion correction mechanisms
Solution Approach 2:
Guide members are introduced as intermediary elements between the unit cells and the stacking jig. These guide members act as mediators that physically guide and constrain the unit cells during insertion, ensuring proper alignment without requiring complex conveyor systems or post-insertion vibration correction
2Productivity
If unit cells are dropped into stacking jig, then stacking process is simplified, but unit cells cannot be properly aligned when dropped to difficult-to-correct regions
Solution Approach 1:
The guide members are positioned in advance within the stacking jig to define the correct alignment path. This preliminary arrangement ensures that even when unit cells are dropped from various positions, they will be guided into proper alignment during the insertion process, maintaining both high stacking speed and alignment precision
Solution Approach 2:
Guide members serve as intermediary structures that intervene between the dropped unit cells and the stacking position. They physically guide the unit cells during insertion, ensuring that even cells dropped to difficult-to-correct regions are properly aligned without reducing stacking speed
