Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wire connection methods are used (peeling sheaths, twisting cores, wrapping with insulating tape), then reliable electrical connection is achieved, but the operation becomes complicated and time-consuming
Solution Approach 1:
The patent combines multiple functions into a single integrated connector device: the insulative upper and lower connectors provide both mechanical support and electrical insulation, while the conductive member with cutting blades simultaneously peels the sheath and establishes electrical contact with the wire core. This merging of functions eliminates the need for separate tools and multiple操作步骤, resolving the contradiction between reliability and operational complexity.
Solution Approach 2:
The connector is segmented into distinct functional components: insulative upper connector, insulative lower connector, and conductive member with cutting blades. Each segment performs a specific function (insulation, structural support, wire preparation and electrical contact), allowing the system to achieve reliable connection while simplifying the overall operation through modular design.
2Reliability
If traditional wire connection methods are used (peeling sheaths, twisting cores, wrapping with insulating tape), then reliable electrical connection is achieved, but the connection process becomes time-consuming
Solution Approach 1:
The cutting blades are pre-positioned on the conductive member to perform the sheath-peeling action automatically when the wire is inserted. This preliminary action of sheath removal is integrated into the insertion process itself, eliminating the need for separate peeling operations and significantly reducing connection time while maintaining reliable electrical contact.
Solution Approach 2:
The patent merges the sheath-peeling function and electrical contact establishment into a single integrated action through the conductive member with cutting blades. This combination allows both functions to be performed simultaneously during wire insertion, dramatically reducing the time required compared to traditional sequential operations.
3Reliability
If traditional wire connection methods are used (peeling sheaths, twisting cores, wrapping with insulating tape), then proper electrical contact is achieved, but safety against electric shock is not guaranteed
Solution Approach 1:
The insulative upper and lower connectors serve as intermediary protective elements between the conductive member and the external environment. These insulative components maintain proper electrical contact while providing a barrier that prevents electric shock, thus resolving the contradiction between electrical contact quality and safety.
Solution Approach 2:
The connector structure automatically provides insulation protection through its design: the insulative upper and lower connectors enclose the conductive member and cutting blades, creating an inherent safety mechanism that protects users from electric shock while maintaining effective electrical connection without requiring additional protective measures.
