Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex assembly processes are used to mount and connect multiple rechargeable battery cells, then mounting reliability is improved, but assembly time increases and productivity decreases
Solution Approach 1:
The cell holder is segmented into multiple independent cell receiving spaces, each capable of holding individual battery cells. This segmentation allows for modular assembly where cells can be independently positioned and secured, improving both reliability through proper positioning and productivity through parallel assembly operations
Solution Approach 2:
The cell holder incorporates positioning protrusions and corresponding positioning grooves that automatically align and secure battery cells without requiring additional fastening operations. The elastic contact between these features provides self-adjusting positioning that ensures reliable mounting while eliminating time-consuming manual alignment steps
2Stability of the object's composition
If multiple cell holders are combined to support multiple battery cells, then support stability is improved, but device complexity increases
Solution Approach 1:
Multiple cell holders are merged into a single integrated structure with a common base body that contains multiple receiving spaces. This unified design provides stable support for multiple battery cells while reducing overall device complexity compared to using separate, discrete cell holders for each cell
Solution Approach 2:
The cell holder base body serves multiple functions simultaneously: it provides structural support, contains positioning features for cell alignment, incorporates elastic contacts for electrical connection, and offers thermal management pathways. This multi-functionality reduces the number of separate components needed, simplifying the overall device while maintaining support stability
3Reliability
If elastic contacts are used to connect battery cells to the cell holder, then electrical connection reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The elastic contact features are designed with optimized geometric parameters including curvature radius, thickness, and positioning dimensions. These parameter optimizations ensure that the elastic deformation characteristics provide reliable electrical contact while compensating for normal manufacturing tolerances, reducing the stringency of precision requirements

AI summary
A rechargeable battery pack includes a rechargeable battery cell, and a pair of cell holders receiving respective sides of the rechargeable battery cell in a length direction, the pair of cell holders being combinable with each other. Each of the cell holders includes a base that supports the rechargeable battery cell, a combination protrusion and a combination groove symmetrically disposed on an outer side of the base, a protrusion protruding from the base in the length direction so as to be combinable in the length direction, and a recess portion being concave in the base in the length direction such that the recess portion of one of the pair of cell holders is combinable with the protrusion of the other of the pair of cell holders.
