Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cells are arranged aligned on a flat support and held by parallel plates, then mechanical assembly is achieved, but individual cell extraction requires dismantling significant part of the assembly
Solution Approach 1:
The support is divided into multiple independent bay zones, each capable of holding individual cells. The fixing devices are segmented into separate first and second fixing devices that can independently engage with cell lugs. This segmentation allows individual cells to be accessed and removed without affecting other cells in the assembly.
Solution Approach 2:
The fixing devices incorporate rotatable elements that transition between engaged and disengaged positions. The first fixing device rotates to engage/disengage from cell lugs, and the second fixing device with elastically deformable elements provides dynamic locking. This dynamic mechanism enables quick individual cell extraction without dismantling the entire assembly.
2Ease of repair
If parallel plates are used to hold cells at both ends, then mechanical stability is achieved, but disassembly requires significant effort
Solution Approach 1:
The fixing devices use rotatable and elastically deformable elements that can quickly transition between locked and unlocked states. The second fixing device's elastically deformable elements can be easily actuated to release cells, enabling rapid cell replacement and reducing maintenance time.
Solution Approach 2:
The fixing mechanism is designed to extract individual cells from the assembly independently. The first fixing device engages with lugs on one end of the cell, and the second fixing device engages with lugs on the other end, allowing the cell to be individually extracted without removing other cells or dismantling the entire assembly structure.
3Productivity
If fixed mechanical assembly is used, then structural stability is achieved, but assembly speed is reduced
Solution Approach 1:
The fixing devices incorporate rotational and elastic deformation mechanisms that can be quickly actuated to secure cells. The elastically deformable elements in the second fixing device provide automatic locking upon engagement, ensuring reliable cell positioning while enabling rapid assembly through simple rotational or elastic actuation.
Solution Approach 2:
The elastically deformable elements in the second fixing device automatically engage and lock cells into position during the assembly process. The cam surfaces and lug interactions are designed to self-align and self-lock, reducing the need for complex adjustment mechanisms while ensuring reliable cell positioning and increasing assembly speed.
