Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a compact design with simple clamping spring and busbar geometry is used, then device complexity is reduced and ease of manufacture is improved, but the ability to securely connect conductors of varying diameters without deformation is worsened
Solution Approach 1:
The contact leg is designed with an elastic spring section that can dynamically deflect and adapt to different conductor diameters. This dynamic flexibility allows the same simple geometry to securely connect conductors of varying sizes without deformation, resolving the contradiction between simple design and adaptability.
Solution Approach 2:
The spring section's elasticity allows it to change its physical state (deflection amount) based on the conductor diameter. This parameter change enables the contact leg to adjust its contact pressure and positioning automatically, achieving versatile conductor connection with simple geometry.
2Reliability
If sufficient spring force is applied to conductors with large cross-section, then contact reliability is improved, but the conductor may undergo undesired deformation due to excessive pressure
Solution Approach 1:
The contact leg features a ramp section with specific geometric properties that distributes the contact force locally. This ramp geometry guides the conductor onto the contact surface in a controlled manner, ensuring sufficient contact pressure for reliability while preventing localized deformation through proper force distribution.
Solution Approach 2:
The elastic spring section provides dynamic force adaptation - it delivers sufficient spring force for large conductors while automatically limiting the pressure to prevent deformation. The spring's inherent elasticity ensures the force is always within safe limits while maintaining reliable contact.
3Device complexity
If the ramp is fixed in position, then the structure is simplified, but conductors of different diameters cannot be optimally guided and contacted
Solution Approach 1:
The ramp is integrated with the elastic spring section, making it dynamically positionable rather than fixed. The ramp deflects with the spring section to adapt to different conductor diameters, providing optimal guidance and contact for each conductor size while maintaining a simple integrated structure.
Solution Approach 2:
The spring section with integrated ramp serves multiple functions: it guides conductors of different diameters, provides elastic contact force, and positions the conductor on the busbar. This multi-functionality achieves adaptability without increasing structural complexity.
