Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the insulating material is removed in a lateral section of the sandwich of layers to provide lateral connecting portions, then the electrical connection capability is improved, but the risk of electrical shock or sparking increases
Solution Approach 1:
The housing is divided into two separable parts that can be opened and closed around the busbar. This segmentation allows the housing to accommodate the exposed conducting layers at the lateral connecting portions while providing insulation when closed, thus resolving the contradiction between electrical connection capability and safety.
Solution Approach 2:
The housing acts as an intermediary insulating structure that surrounds the exposed conducting layers at the lateral connecting portions. This intermediary element provides the necessary insulation without interfering with the electrical connection function, thus resolving the contradiction between connection capability and safety.
2Reliability
If a rigid insulating cover is used to insulate the lateral connecting portion, then the insulation reliability is improved, but the adaptability to varying busbar thicknesses deteriorates
Solution Approach 1:
The housing is designed with flexible elements including resilient brackets and adjustable positioning mechanisms that allow it to adapt dynamically to different busbar thicknesses. This dynamic design maintains reliable insulation contact while accommodating variations in busbar dimensions, thus resolving the contradiction between insulation reliability and adaptability.
Solution Approach 2:
The housing incorporates adjustable parameters such as resilient bracket force and positioning mechanisms that can be modified to accommodate different busbar thicknesses. This allows the housing to maintain reliable insulation contact across varying dimensions, resolving the contradiction between insulation reliability and adaptability.
3Adaptability or versatility
If complex adjustment mechanisms are added to accommodate varying busbar thicknesses, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The resilient brackets are designed to automatically adapt to the busbar thickness through their elastic properties, eliminating the need for complex manual adjustment mechanisms. The housing structure itself provides the adaptation function through its design, thus resolving the contradiction between adaptability and device complexity.
4Stability of the object's composition
If multiple fasteners and adjustment mechanisms are used to secure the insulating cover, then the mounting stability is improved, but the ease of assembly deteriorates
Solution Approach 1:
The housing integrates multiple functions including insulation, mounting, and adaptation into a single unified structure. The resilient brackets and positioning mechanisms are combined with the housing itself rather than being separate components, thus resolving the contradiction between mounting stability and ease of assembly.
