Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a push buckle is disposed on the central position relative to the light guide plate, then the quick-release mechanism can be compact, but the installer cannot access and operate the push buckle with both hands, making installation difficult
Solution Approach 1:
The patent inverts the traditional push-buckle design by replacing it with a rotating buckle mechanism. Instead of pushing a central buckle that is hard to access, the installer rotates the lamp holder body itself to achieve connection. This inversion transforms the operation from manual pushing to rotational movement, solving the accessibility problem while maintaining compactness.
Solution Approach 2:
The rotating buckle mechanism allows the lamp holder to serve itself during installation. The installer simply rotates the lamp holder body, and the built-in buckle automatically engages with the light guide plate without requiring manual operation of a separate push-buckle component. This self-service approach eliminates the need for difficult-to-access central buckles.
2Ease of manufacture
If plastic casings are used for quick-release mechanisms, then the device can be lightweight and easy to manufacture, but proper grounding effect is not achieved, raising electrical safety concerns
Solution Approach 1:
The patent combines plastic and metal materials in a composite structure. The lamp holder body uses plastic for lightweight and easy manufacturing, while metal components (metal ring, metal buckle) are integrated to provide electrical grounding. This composite approach maintains the manufacturing simplicity of plastic while adding the grounding reliability of metal.
Solution Approach 2:
The metal ring acts as an intermediary component between the plastic lamp holder body and the light guide plate. It transfers the rotational motion and provides the necessary electrical grounding connection, mediating between the non-conductive plastic material and the requirement for electrical safety.
3Weight of moving object
If plastic casings are used for quick-release mechanisms, then the device can be lightweight, but sufficient strength to support heavier lighting fixtures is not provided
Solution Approach 1:
The patent uses composite materials combining plastic and metal to achieve both lightweight properties and high strength. The plastic body provides low weight, while integrated metal components (metal ring, metal buckle) provide the structural strength needed to support heavier lighting fixtures, overcoming the limitation of pure plastic construction.
4Device complexity
If the plug on the lamp base is obstructed by the light guide plate or lamp body, then the design can be compact, but the installation is hindered
Solution Approach 1:
The patent inverts the installation sequence and mechanism. Instead of pushing a plug through an obstructed path, the lamp holder body itself rotates to engage the light guide plate. This inversion eliminates the obstruction problem by changing the fundamental connection method from linear pushing to rotational engagement, allowing compact design without compromising installation accessibility.

AI summary
A connecting device used for electrically connecting a power source with a power consuming module is provided. The connecting device includes a female connecting base and a male connecting base. The female connecting base has two opposite surfaces, a rim disposed on one of the surfaces and two terminals exposed on the surfaces. The terminals are connected to the live wire and neutral wire of the power source separately. The male connecting base includes a clamp, two conductive strips, and a ground strip. The rim is clamped, and the male connecting base is fastened to the female connecting base by the clamp. The terminals are connected to the conductive strips, while the end surface of each conductive strip protrudes from the surface of the male connecting base. The ground strip includes a ground surface which protrudes from the end surfaces of the conductive strips.
