Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the structure of the connection terminal is made compact, then the device size is reduced, but the ease of wire insertion and stability of electrical connections deteriorate
Solution Approach 1:
The connection terminal is divided into distinct functional modules: a housing containing a contact assembly with multiple clamping points, each comprising a spring steel plate with elastic tongues and a bus bar. This segmentation allows each component to be optimized independently - the elastic tongues provide insertion assistance while the bus bar ensures stable electrical connection, resolving the contradiction between compact size and ease of operation.
Solution Approach 2:
The spring steel plate with elastic tongues introduces dynamic elements into the compact structure. The elastic tongues can deform during wire insertion to guide and assist the conducting wire, then return to their original position to maintain stable electrical contact. This dynamic behavior enables ease of wire insertion while maintaining a compact overall structure.
2Volume of moving object
If the structure of the connection terminal is made compact, then the device size is reduced, but the reliability of electrical connections deteriorates
Solution Approach 1:
The contact assembly is segmented into multiple independent clamping points, each with its own spring steel plate, elastic tongues, and bus bar contact. This segmentation ensures that each electrical connection point can maintain stable contact independently, preventing failure of the entire connector due to a single point of failure, thus improving reliability within a compact form factor.
Solution Approach 2:
The spring steel plate is designed with specific elastic properties and pre-tension forces to maintain optimal contact pressure on the conducting wires. The elastic tongues are configured with specific deformation characteristics to ensure reliable electrical contact while accommodating wire insertion. These parameter optimizations enable stable electrical connections in a compact structure.
3Ease of manufacture
If the structure of the connection terminal is simplified, then the manufacturing cost is reduced, but the stability after wire installation deteriorates
Solution Approach 1:
The spring steel plate integrates multiple functions into a single component: it provides the clamping force through elastic deformation, forms the electrical contact path, and includes integrated elastic tongues for wire guidance and insertion assistance. This merging of functions reduces the number of separate parts needed, simplifying manufacturing while maintaining stable wire installation through the inherent elastic properties of the integrated structure.

AI summary
A novel connection terminal includes a housing, a contact assembly and a support member. The conductive clip is integrally bent and formed by spring steel plate, and two ends of a tongue forming section of the conductive clip are respectively connected to a supporting section and an approximately C-shaped cavity section by a pre-deformed elastic arch structure. Thus, the conductive clip and the bus bar form a clamping space in which the conducting wire can be more elastically crimped, ensuring that the conducting wire is firmly connected to the connection terminal assembly, allowing stable electrical connection between multiple conducting wires. The interior of the approximately C-shaped cavity section communicating with the wire passage enlarges the accommodating space for the conducting wire accordingly, facilitates the quick insertion of the conducting wire and provides more elastic and effective pressing force.
