Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connection terminal structure with insulating case and connection clamp is used, then electrical connection can be established, but structural complexity increases and manufacturing cost rises
Solution Approach 1:
The patent merges the basic element and clamping element into a single integrated component. The basic element provides structural support and engagement features, while the clamping element provides the resilient clamping force. These two functional elements are combined into one piece that can be molded as a single unit, eliminating the need for separate insulating cases and connection clamps, thereby reducing structural complexity while maintaining electrical connection reliability
Solution Approach 2:
The integrated connection terminal structure performs multiple functions: the basic element provides structural support and positioning, the engaging flange and shoulder portions provide mechanical engagement, and the resilient clamping arm provides electrical connection. This multi-functional design eliminates the need for separate specialized components, reducing overall device complexity
2Reliability
If conventional connection terminal structure with multiple components is used, then electrical connection is achieved, but manufacturing cost increases
Solution Approach 1:
By combining multiple components into a single integrated structure that can be molded in one piece, the patent eliminates the need for separate manufacturing processes for insulating cases and connection clamps. This single-mold construction reduces manufacturing steps, material waste, and assembly operations, thereby lowering production costs while maintaining reliable electrical connection functionality
3Reliability
If conventional connection terminal structure with resilient clamping arm is used, then electrical connection is established, but assembly process becomes intricate
Solution Approach 1:
The patent integrates the resilient clamping arm with the basic element into a single component. The clamping element is molded as one piece with the basic element, with the resilient clamping arm extending from the integrated structure. This eliminates the need for separate assembly of the clamping arm with the insulating case, simplifying the assembly process to merely inserting the wire through the guiding groove and engaging it with the clamping element
Solution Approach 2:
The integrated structure features self-aligning engagement mechanisms where the guiding groove automatically positions the wire, and the resilient clamping arm automatically clamps the wire upon engagement with the basic element. This self-service design reduces the complexity of assembly operations and minimizes the need for precise manual alignment during assembly

AI summary
A connection terminal structure includes a basic element and a clamping element. The basic element is bent to be L-shaped and includes a longitudinal arm and a transverse arm connected to the longitudinal arm. An upper end of the longitudinal arm forms an engaging flange and an engaging shoulder portion. A right end of the transverse arm forms a joint portion. The clamping element comprises a resilient clamping arm, a supporting arm, and a connecting arm. The connecting arm forms an opening portion and extends from the supporting arm to the longitudinal arm. The opening portion fits around the engaging shoulder portion. A lower end of the supporting arm forms a joint end jointed to the joint portion. The resilient clamping arm connects with the supporting arm, extends to the longitudinal arm, has a front end engaging with the engaging flange, and penetrates the opening portion to move resiliently.
