Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bus bar is used for conductor connections in existing connecting terminals, then the structural strength and electrical conductivity are improved, but the device complexity and weight increase
Solution Approach 1:
The invention extracts and eliminates the bus bar component from the connecting terminal system. Instead of using separate bus bars to connect conductors, the patent implements direct clamping of conductors to each other through clamping springs, thereby removing the bus bar and reducing device complexity while maintaining connection functionality
Solution Approach 2:
The invention merges the functions of the bus bar (electrical conduction and mechanical support) directly into the clamping mechanism. The clamping springs not only provide mechanical clamping force but also serve as the electrical conduction path, combining multiple functions into a single integrated component system
2Reliability
If multiple components are used in existing connecting terminals, then the reliability of conductor connection is improved, but the manufacturing complexity and production effort increase
Solution Approach 1:
By removing the bus bar and reducing the number of components, the invention simplifies the assembly process and manufacturing steps while maintaining reliable conductor connection through the direct clamping mechanism
Solution Approach 2:
The clamping springs are designed to automatically clamp the conductors together when inserted, providing self-servicing functionality that ensures reliable connection without requiring complex assembly procedures or additional fastening operations
3Reliability
If conductors are connected via bus bar sections in existing terminals, then the electrical conductivity is maintained, but the weight and device complexity increase
Solution Approach 1:
The invention extracts and removes the heavy bus bar sections from the connecting terminal, replacing them with lightweight clamping springs that provide both mechanical clamping and electrical conduction functions
Solution Approach 2:
The clamping springs are made from spring steel, potentially with high-conductivity material coatings, creating a composite structure that combines mechanical strength with electrical conductivity in a lightweight component
4Device complexity
If conductors are clamped directly to each other without bus bar, then the device complexity is reduced, but the reliability of electrical connection may worsen
Solution Approach 1:
The clamping springs automatically apply clamping force to ensure reliable electrical contact between conductors, with the spring force maintaining consistent pressure and electrical conductivity throughout operation
Solution Approach 2:
The use of spring steel with potential high-conductivity coatings on the clamping springs ensures that the direct conductor-to-conductor connection maintains high electrical conductivity while providing mechanical reliability
