Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the profile of the connector is reduced, then the height is decreased, but the reliability of connection between shield members deteriorates
Solution Approach 1:
The second terminal incorporates a spring part that enables elastic deformation, allowing the contact part to dynamically adjust during connection. When the contact part is pushed forward, the spring part elastically deforms to maintain contact pressure, ensuring reliable connection even in a compact profile design.
Solution Approach 2:
The first terminal features an inclined surface that guides the contact part during insertion. This preliminary guiding action ensures proper alignment before the contact part engages with the contact surface, preventing misconnection and enhancing connection reliability in the reduced-height structure.
2Length of moving object
If the profile is reduced, then the height is decreased, but the alignment precision between terminals deteriorates
Solution Approach 1:
The inclined surface of the first terminal performs preliminary alignment guidance during insertion. This guiding action occurs before the final contact, ensuring that the contact part and contact surface are properly aligned even in the compact height design.
Solution Approach 2:
The inclined surface acts as an intermediary guiding element between the contact part and the contact surface. It mediates the insertion process by gradually guiding the contact part into proper alignment, preventing direct misalignment that would occur without this intermediate guiding structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a reduced profile while ensuring reliable connections and minimizing solder spread, thereby enhancing connection stability and reducing the risk of deformation.
Implementation Method 1
The contact part is displaced in a forward direction when the contact part is pushed in the forward direction to cause the spring part to elastically deform

AI summary
In a connector, a contact part is exposed from a resin body member at a surface facing in a rearward direction of the resin body member. The contact part is displaced in a forward direction when the contact part is pushed in the forward direction to cause the spring part to elastically deform. There is no other terminal between the contact part and an inclined surface. The contact part is located below the inclined surface.
