Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid terminal connection is used, then structural stability is improved, but assembly tolerance absorption is reduced
Solution Approach 1:
The first and second connection portions are designed with elastic deformation capability, transforming the rigid structure into a dynamic one that can adapt to assembly variations. These portions can elastically deform during insertion and connection, absorbing assembly tolerances while maintaining stable contact points. The coupling portion maintains structural integrity, providing the necessary rigidity for overall stability.
Solution Approach 2:
The elastic deformation capability of the first and second connection portions acts as a pre-designed cushioning mechanism that absorbs assembly tolerances before final connection is achieved. This beforehand cushioning allows for easier assembly while ensuring stable contact points are formed, eliminating the need for extremely precise manufacturing tolerances.
2Reliability
If elastic deformation capability is added to terminals, then contact pressure stability is improved, but device complexity increases
Solution Approach 1:
The patent merges the elastic deformation function and connection function into a single integrated relay terminal structure. The first and second connection portions are formed as integral parts of the relay terminal body, eliminating the need for separate elastic elements or additional components. This merging approach maintains contact pressure stability through elastic deformation while avoiding the complexity of multi-component assemblies.
