Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof structure is used to protect the electrical connector inside the casing, then the electrical connector is protected from rain or dust, but the structure becomes complex and additional adapter cables are needed
Solution Approach 1:
The cable auxiliary device is nested within the casing structure, with the housing containing the clamp element, movement element, and latch mechanism. This nested arrangement allows the waterproof function to be integrated into the existing casing without requiring separate adapter cables or complex external waterproof structures.
Solution Approach 2:
The cable auxiliary device performs multiple functions: it provides waterproof protection through the sealed housing, enables cable insertion and removal through the clamp and movement elements, and maintains electrical connectivity. This multi-functionality eliminates the need for separate adapter cables while achieving reliable waterproof protection.
2Reliability
If adapter cables are used to connect the electrical connector inside the casing, then waterproof protection is achieved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the waterproof housing structure with the cable connection mechanism into a single integrated cable auxiliary device. This combination eliminates the need for separate adapter cables, reducing the number of components that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining waterproof protection.
Solution Approach 2:
The cable auxiliary device serves as both the waterproof seal and the cable connection interface, replacing the need for separate adapter cables. This multi-functional design reduces component count and simplifies the manufacturing process while ensuring reliable waterproof protection.
3Reliability
If additional adapter cables are used for connection, then waterproof integrity is maintained, but the device complexity and cost increase
Solution Approach 1:
The cable auxiliary device nests all necessary components (housing, clamp element, movement element, latch) within a single integrated structure that fits inside the casing. This eliminates the need for separate adapter cables while maintaining waterproof integrity through the sealed housing design.
Solution Approach 2:
The patent combines the waterproof sealing function with the cable connection function into a single integrated device. This merging of functions reduces the total number of components compared to using separate adapter cables, thereby reducing device complexity while maintaining waterproof integrity.

Function Achieved in This Case
Reduces manufacturing costs by eliminating the need for adapter cables while maintaining waterproof integrity.
Implementation Method 1
In the initial state, two ends of the elastic element are respectively connected to the housing and the clamp element, wherein the elastic element pushes the clamp element and the movement element in a direction from the housing toward the front wall through elastic force

AI summary
A cable-auxiliary device includes a housing, a clamp element, and a movement element. The housing includes a first protrusion. The clamp element is movably disposed in the housing, and includes a clamp arm a second protrusion disposed on the clamp arm. The movement element is movably disposed on the housing. The housing is adjacent to an electrical connector, and a plug of a cable is inserted into the electrical connector through the clamp element. The clamp element is moved by pulling the movement element, so that the clamp arm clamps the plug, and pulls the plug from the electrical connector. During the clamp arm clamping the plug, the first protrusion pushes the second protrusion so that the clamp arm clamps the plug.
