Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible conductive cables are used to electrically interconnect stacked battery units, then electrical contact is achieved, but safety risks increase due to unpredictable cable orientation and potential short circuits
Solution Approach 1:
The patent extracts the harmful conductive cable from the assembly process and replaces it with a non-conductive positioning element that performs only positioning function, eliminating the short circuit risk while maintaining electrical connection capability through separate busbar structures
Solution Approach 2:
The positioning element acts as an intermediary component that mediates between battery units during assembly, providing precise positioning without conducting electricity, thus separating the positioning function from the electrical connection function to eliminate safety hazards
2Reliability
If additional safety measures and protective components are added during assembly, then safety is improved, but assembly time increases
Solution Approach 1:
The patent removes the need for additional safety measures by extracting the hazardous conductive cable from the positioning function, allowing assembly to proceed without extra protective components or procedures while maintaining safety
Solution Approach 2:
The positioning element inherently provides safety through its non-conductive material property, eliminating the need for separate safety measures and protective apparatuses, thus reducing assembly complexity and time
3Manufacturing precision
If rigid positioning structures are used to position battery units, then positioning precision is improved, but risk of jamming increases during assembly
Solution Approach 1:
The positioning element incorporates dynamic adjustment capability through its displaceable design, allowing it to adapt to manufacturing tolerances and prevent jamming while maintaining precise positioning through controlled movement in perpendicular planes
4Reliability
If larger installation space is provided to accommodate safety measures, then safety is improved, but installation space increases
Solution Approach 1:
The patent eliminates the need for additional safety apparatuses and protective components by removing the hazardous conductive cable from the positioning function, thereby reducing the installation space requirement while maintaining safety through the non-conductive positioning element
