Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a complex structure is used for fixing rechargeable batteries, then the batteries can be stably supported, but the assembly efficiency of the battery module is reduced
Solution Approach 1:
The holder is divided into multiple storage spaces with barriers, allowing batteries to be independently positioned and fixed. This segmentation provides stable support for each battery while maintaining a simple overall structure that facilitates efficient assembly.
Solution Approach 2:
The holder acts as an intermediary component between the batteries and the housing. It provides a simple interface that simultaneously achieves stable battery support and easy assembly, resolving the contradiction between stability and assembly efficiency.
2Stability of the object's composition
If the protective circuit module is tightly fixed in the housing, then it can be stably supported, but heat dissipation becomes difficult
Solution Approach 1:
The housing provides stable support for the protective circuit module at specific locations while maintaining open spaces and thermal pathways in other areas. This local differentiation allows simultaneous achievement of stability and heat dissipation.
Solution Approach 2:
Heat is extracted from the protective circuit module through dedicated thermal pathways and is separated from the structural support function. This allows the module to be stably fixed while heat is actively removed through the housing structure.
3Productivity
If simple fixing structures are used, then assembly efficiency is improved, but the protective circuit module cannot be stably fixed
Solution Approach 1:
The housing structure serves multiple functions simultaneously: it provides mechanical support for stable fixation of the protective circuit module, facilitates heat dissipation through thermal pathways, and enables efficient assembly through its integrated design. This multi-functionality resolves the contradiction between simplicity and stability.
4Temperature
If heat dissipation structures are added to the housing, then heat dissipation is improved, but the device complexity increases
Solution Approach 1:
The heat dissipation function is merged with the housing structure itself. The housing simultaneously serves as the enclosure, the support structure, and the heat dissipation pathway, eliminating the need for separate heat dissipation components and maintaining structural simplicity.
