Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing connecting terminals are designed with multiple separate components to achieve reliable electrical connection, then connection reliability is improved, but device complexity and assembly time increase
Solution Approach 1:
The patent combines the insulating support structure and the conductor guiding function into a single integrated inner piece component. This inner piece is inserted into the housing and provides both mechanical support for the clamping springs and guidance for the conductors, eliminating the need for separate support and guiding components while maintaining reliable electrical connections.
Solution Approach 2:
The inner piece serves multiple functions simultaneously: it provides electrical insulation between conductors, mechanically supports the clamping springs, guides the conductors during insertion, and maintains the structural integrity of the terminal. This multi-functional design reduces the total number of components while ensuring reliable operation.
2Reliability
If traditional connecting terminals use multiple separate parts for support and guidance, then functional requirements are met, but assembly becomes cumbersome and time-consuming
Solution Approach 1:
The terminal is divided into two main segments: a reusable housing that contains the contact elements, and a replaceable inner piece that combines support and guidance functions. This segmentation allows the inner piece to be pre-assembled and tested separately, then quickly inserted into the housing, significantly reducing assembly time while maintaining all necessary functional performances.
Solution Approach 2:
The inner piece is pre-assembled with the clamping springs and contact elements before insertion into the housing. This preliminary assembly ensures proper positioning and alignment, eliminating the need for complex alignment procedures during final assembly and reducing overall assembly time while ensuring functional reliability.
3Ease of manufacture
If connecting terminals are simplified with fewer components, then assembly is easier, but mechanical support and electrical insulation may be compromised
Solution Approach 1:
The inner piece is made from composite materials that combine high mechanical strength with excellent electrical insulation properties. This allows a single component to provide both the structural support necessary for reliable clamping and the electrical insulation required for safe operation, simplifying the design without compromising strength or insulation.
