Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electricity storage elements are individually contained in cell cases, then positioning and protection of electricity storage elements is improved, but the number of components increases
Solution Approach 1:
The patent combines multiple functions (positioning, protection, and electrical insulation) into a single integrated insulating protector structure. This consolidator structure replaces the need for separate cell cases for each electricity storage element, thereby reducing the total number of components while maintaining positioning and protection functions.
Solution Approach 2:
The insulating protector is designed to perform multiple functions simultaneously: it provides mechanical protection for the electricity storage elements, ensures proper positioning through integrated positioning structures, and provides electrical insulation. This multi-functional design eliminates the need for separate dedicated components for each function.
2Reliability
If separate cell cases are used for each electricity storage element, then individual protection is improved, but assembly complexity increases
Solution Approach 1:
Multiple separate cell cases are merged into a single integrated insulating protector structure that accommodates multiple electricity storage elements. This consolidation simplifies the assembly process by reducing the number of individual components that need to be assembled and positioned separately.
3Manufacturing precision
If multiple positioning members are attached to electricity storage elements, then positioning precision is improved, but the number of components increases
Solution Approach 1:
The positioning function is merged into the insulating protector structure itself through integrated positioning structures. This eliminates the need for separate positioning members attached to each electricity storage element, thereby maintaining positioning precision while reducing the total number of components.
Solution Approach 2:
The insulating protector is designed with pre-formed positioning structures that automatically position the electricity storage elements when assembled. This preliminary positioning design eliminates the need for additional positioning operations or separate positioning components during assembly.
