Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electrical connector size is reduced to fit compact electronic devices, then the compactness is improved, but the ability to protect larger diameter signal lines deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the cover movable relative to the wire inlet portion, allowing the wire inlet hole size to be dynamically adjusted. The cover can be positioned at different locations to create different wire inlet hole sizes, enabling the connector to adapt to different signal line diameters. This resolves the contradiction by allowing a compact connector design that can still accommodate and protect larger diameter signal lines when needed.
Solution Approach 2:
The patent applies parameter changes by varying the size of the wire inlet hole through the movable cover mechanism. By changing the position of the cover, the effective opening size through which signal lines pass is adjusted. This allows the same compact connector to handle different signal line diameters, resolving the contradiction between compact size and protection capability for larger wires.
2Reliability
If the electrical connector size is increased to accommodate larger diameter signal lines, then the signal line protection is improved, but the compactness deteriorates
Solution Approach 1:
The movable cover creates a dynamic structure where the connector maintains a compact form factor but can expand the wire inlet hole size on demand. The cover moves to different positions to create larger or smaller openings, allowing the connector to protect larger diameter signal lines without permanently increasing its overall size.
Solution Approach 2:
The cover structure is nested within the connector housing, and when moved to certain positions, it effectively creates a larger passage for signal lines. The nested design allows the connector to maintain compact dimensions while providing adequate protection and accommodation for larger diameter signal lines when the cover is positioned appropriately.
3Device complexity
If a fixed size wire inlet hole is used, then the device complexity is reduced, but the adaptability to different signal wire sizes deteriorates
Solution Approach 1:
The patent introduces a dynamic element (movable cover) that allows the wire inlet hole size to be adjusted based on the signal wire diameter. This single movable component provides adaptability for different wire sizes without requiring multiple different connector designs, thus maintaining relatively simple device complexity while significantly improving adaptability.
Solution Approach 2:
The movable cover mechanism enables a single connector design to serve multiple functions by accommodating different signal wire diameters. The cover can be positioned to create appropriate openings for various wire sizes, making the connector universal and adaptable without requiring complex multi-size designs or multiple components.

AI summary
An electrical connector includes a main body, a first cover, and a second cover. The main body includes a first connection portion, a wire inlet portion, and an accommodating space between the first connection portion and the wire inlet portion. The first cover is pivotally connected to the first connection portion to be rotatable relative to the main body between a first position and a second position. When the first cover is at the first position, the accommodating space is opened for installation. When the first cover is at the second position, the first cover at least partially closes the accommodating space for protection. The second cover is connected to the first cover and separably encloses a wire inlet hole with the wire inlet portion. The second cover is movable relative to the wire inlet portion to adjust the size of the wire inlet hole.
