Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional zipper switch lampholders have complex internal structures, difficult assembly processes, high manufacturing costs, and rely on UL knots for tensile resistance, which are inefficient and increase storage and transportation costs.
Innovation Solution
A zipper switch lampholder design that uses a zipper to indirectly pull a rotating conductive rod, allowing it to jump between conductive and non-conductive slopes for switching a light emitting element, and incorporates hooks for secure wire connections without the need for UL knots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional zipper switch lampholder uses conductive plates in plug slots to connect power lines, then electrical connection is achieved, but the structure becomes complex and assembly becomes difficult
Solution Approach 1:
The patent removes the complex internal conductive plates and plug slots from the housing. Instead, it uses simple external screw terminals on the housing surface for wire connection, and a simple snap-action switch mechanism inside, dramatically simplifying the internal structure while maintaining reliable electrical connection
Solution Approach 2:
The patent divides the device into distinct functional modules: the housing with screw terminals for wire connection, the simple switch mechanism with spring and contact points, and the lamp socket. This modular segmentation simplifies both the internal structure and assembly process
2Reliability
If a conventional zipper switch lampholder requires tying an UL knot to increase tensile resistance, then wire connection security is improved, but manufacturing time and cost increase
Solution Approach 1:
The screw terminals are designed to self-secure the wire through the screw mechanism, eliminating the need for external UL knots. The screw terminal structure inherently provides both electrical connection and mechanical wire securing in one integrated component, improving manufacturing efficiency
Solution Approach 2:
The patent combines the electrical connection function and the wire securing function into a single screw terminal component. The screw terminal simultaneously provides electrical conductivity and mechanical retention of the wire, eliminating the need for separate UL knot tying
3Strength
If a conventional zipper switch lampholder uses an UL knot to prevent power line detachment, then tensile resistance is increased, but storage and transportation costs increase due to larger volume
Solution Approach 1:
The screw terminal integrates both electrical connection and mechanical wire retention functions into one compact component, eliminating the need for additional UL knot volume. The wire is secured within the compact housing volume through the screw terminal, maintaining small overall device volume while providing sufficient tensile resistance
4Ease of operation
If a conventional zipper switch lampholder uses complex internal structure with multiple components, then switching function is achieved, but assembly process becomes difficult and manufacturing cost increases
Solution Approach 1:
The device is segmented into simple, standardized components: housing with screw terminals, basic snap switch mechanism with spring and contact points, and lamp socket. These segmented components are easy to manufacture and assemble, reducing assembly difficulty while maintaining full switching functionality
Solution Approach 2:
The screw terminals serve multiple functions: electrical connection, wire mechanical retention, and structural mounting points. The simple snap switch mechanism provides both the switching action and the snap-action feedback. This multi-functionality reduces the number of separate components needed, simplifying assembly
