Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bus bars are connected through an intermediate electronic component, then electrical connection is achieved, but connection time and complexity increase
Solution Approach 1:
The patent removes the intermediate electronic component from the connection path between bus bars. By extracting this unnecessary element, the connection is simplified to direct contact between bus bar tip portions, eliminating the time-consuming steps of connecting to and from the electronic component while maintaining reliable electrical connection.
Solution Approach 2:
The patent merges the electrical connection function directly between bus bars by bringing tip portions into direct contact. This combining of connection elements eliminates the intermediate electronic component and reduces the number of connection steps, thereby reducing connection time while ensuring reliable electrical connection.
2Reliability
If bus bars are connected through an intermediate electronic component, then electrical connection is achieved, but connection process complexity increases
Solution Approach 1:
The patent extracts and removes the intermediate electronic component from the connection system. This elimination simplifies the connection process by reducing the number of components and steps involved, making the overall system less complex while maintaining the essential electrical connection function.
Solution Approach 2:
Instead of connecting bus bars through an intermediate electronic component (complex path), the patent inverts the approach by establishing direct contact between bus bar tip portions (simple path). This inversion of the connection methodology fundamentally simplifies the process while ensuring reliable electrical connection.
3Productivity
If bus bar tip portions are directly contacted and jointly fastened, then connection efficiency improves, but fastening precision requirements increase
Solution Approach 1:
The patent employs preliminary positioning structures that pre-align the bus bar tip portions before fastening. By performing positioning actions in advance, the system reduces the precision requirements during the actual fastening operation, allowing for efficient direct contact connection while maintaining manufacturing feasibility.
