Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional connectors with universal specification are used, then adaptability is improved, but reliability deteriorates due to loosening and detachment issues
Solution Approach 1:
The connector is divided into multiple functional components: an outer casing with hook holes, an inner casing with engaging arms, and a resilient component. This segmentation allows each part to perform its specific function - the outer casing provides universal compatibility, while the inner casing with engaging arms provides secure connection, and the resilient component ensures maintaining force.
Solution Approach 2:
The inner casing is nested within the outer casing, with the engaging arms extending from the inner casing through the hook holes of the outer casing. This nested structure allows the engaging mechanism to be integrated within the universal connector housing, combining both adaptability and reliability in a single component.
2Reliability
If specially-designed connector plugging structure is used, then reliability is improved, but adaptability deteriorates due to limited scope of application
Solution Approach 1:
The outer casing is designed with a universal specification (such as USB Type-C) that can be accommodated by standard receptacles. The engaging arms with hook portions provide the secure connection function, making the connector universally compatible while maintaining reliable connection through the engaging mechanism.
3Reliability
If engaging arms with hook portions are added, then reliability is improved, but device complexity increases
Solution Approach 1:
The engaging arms are integrated as part of the inner casing structure, and the hook portions are formed as extensions of these arms. The resilient component is positioned between the inner and outer casings to provide the necessary maintaining force. This merging of functions into integrated components achieves reliable connection without excessive complexity.

AI summary
A connector plug, abutting structure of the same, and electrical connection mechanism having the same are provided. The connector plug includes a connection body and an outer casing member. The outer casing member is disposed outside the connection body and includes an inner casing, an outer casing movably fitted to the inner casing from outside, and a resilient component acting between the inner casing and the outer casing. At least one hook hole is disposed at the front end of the outer casing. At least one engaging arm is disposed on the inner casing and extends forward to form a hook portion. At least one engaging hole is disposed on a receptacle. When a plug is plugged into the receptacle, the hook portion becomes engaged with the engaging hole to achieve connection.
