Solution Overview
Problem
Conventional push handle switch lampholders face challenges such as complex assembly, large volume leading to high manufacturing and storage costs, unsmooth operation due to spring force issues, and short service life due to contact point wear and heat generation.
Innovation Solution
A redesigned push handle switch lampholder with a cylindrical shell, insulating plate, insulating base, and push handle that uses a lower conductive plate to move like a see-saw, allowing easy control of the light emitting element's power connection, featuring a compact design and reduced volume, and utilizing a connecting element to secure components, thus simplifying assembly and improving durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional push handle switch lampholder uses multiple conductive plates and a spring mechanism, then the switching function is achieved, but the assembly becomes complex and the volume increases
Solution Approach 1:
The patent extracts and eliminates the spring component from the conventional switch mechanism. The push handle directly pushes the lower conductive plate to achieve switching without requiring a spring for restoration, thereby simplifying the assembly structure while maintaining the switching function.
Solution Approach 2:
The patent segments the conductive plate into an upper and lower configuration, where the lower conductive plate is pushed by the handle and the upper conductive plate remains stationary. This segmentation allows for a simpler mechanism compared to using multiple movable plates with spring restoration.
2Ease of operation
If the spring force is increased to ensure smooth operation, then the switching action is more reliable, but the pushing operation becomes difficult
Solution Approach 1:
The spring component is completely removed from the mechanism. The push handle directly acts on the lower conductive plate without any spring intervention, eliminating the trade-off between spring force and pushing ease. The operation becomes smooth simply by pushing the plate along its predetermined path.
3Manufacturing precision
If the contact area between conductive plates is reduced to a point or line, then the switching precision is improved, but heat generation increases and service life decreases
Solution Approach 1:
The patent introduces a sliding contact mechanism where the lower conductive plate moves along a predetermined path and slides against the upper conductive plate. This dynamic sliding contact maintains continuous surface contact rather than point or line contact, distributing the electrical current over a larger area and reducing heat generation at any single point, thereby extending service life while maintaining switching precision.
