Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional plug terminal structure is used, then the device complexity is low, but the connection reliability deteriorates under vibration conditions
Solution Approach 1:
The elastic sheet is designed to be deformable, allowing it to dynamically adapt to vibration forces. The elastic sheet can bend and deform under external vibration, maintaining continuous contact between contact portions and the socket terminal, thereby maintaining connection reliability under dynamic vibration conditions.
Solution Approach 2:
The elastic sheet functions as a flexible thin film structure that provides elastic deformation capability. This flexible structure allows the contact portions to maintain pressure contact with the socket terminal during vibration, preventing connection failure without requiring complex rigid locking mechanisms.
2Stability of the object's composition
If multiple locking mechanisms are added to improve connection stability, then the connection reliability improves, but the device complexity increases
Solution Approach 1:
Different portions of the plug terminal are assigned different functions: the body portion provides structural support, the elastic sheet provides elastic deformation and continuous contact pressure, and the contact side plates provide lateral stability. This functional differentiation achieves multi-directional stability without requiring a uniformly complex structure throughout.
Solution Approach 2:
The invention combines multiple functions into a single integrated elastic sheet structure that simultaneously provides elastic support, contact pressure, and vibration resistance. The contact side plates are also integrated to provide both structural support and lateral contact stability, reducing the need for separate locking components.
3Reliability
If the plug terminal structure is simplified for easy assembly, then the ease of operation improves, but the connection reliability under vibration deteriorates
Solution Approach 1:
The elastic sheet automatically adjusts its deformation state based on insertion force and vibration conditions. During assembly, the elastic sheet deforms to accommodate insertion, then automatically rebounds to provide contact pressure, eliminating the need for manual adjustment or complex locking operations while maintaining connection reliability.

AI summary
A plug terminal includes a cable connection portion and an insertion portion. The insertion portion is inserted into a socket terminal. The insertion portion has a body plate, an elastic sheet having resilience, and two contact side plates. One end of the elastic sheet extends and is bent from a middle portion of the body plate. An other end of the elastic sheet extends in a direction away from the body plate. The other end of the elastic sheet has a pressing portion. Each contact side plate extends on one side of the body plate and is in electrical contact with the socket terminal.
