Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp holder structures are overly complex, requiring cumbersome external lock screws for wire fixation, leading to inefficient installation and assembly processes.
Innovation Solution
A lamp holder with a simplified structure featuring a wire fixing device integrated into the bottom cover, comprising a base ring, clamping blocks, and barb teeth that securely clamp the wire, preventing pull-out and simplifying installation by eliminating the need for external screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external lock screws are used to fix the wire, then the wire can be prevented from being pulled out, but the installation procedure becomes cumbersome and assembly efficiency decreases
Solution Approach 1:
The patent extracts the wire fixation function from the external lock screw system and integrates it into the lamp holder bottom cover structure. The barb teeth are directly formed on the clamping blocks within the bottom cover, eliminating the need for separate external fastening components and simplifying the assembly process while maintaining reliable wire fixation.
Solution Approach 2:
The patent merges the wire clamping function with the lamp holder bottom cover structure by integrating clamping blocks with barb teeth directly into the bottom cover body. This combination eliminates the need for separate external lock screws and reduces the number of assembly steps, thereby improving assembly efficiency while ensuring wire fixation reliability.
2Reliability
If external lock screws are used to fix the wire, then the wire can be secured, but the structure becomes overly complicated
Solution Approach 1:
The patent removes the external lock screw components from the holder structure and extracts the wire fixation function into the bottom cover itself. The clamping blocks with barb teeth are integrated directly into the bottom cover, simplifying the overall structure by eliminating separate external fastening hardware.
Solution Approach 2:
The patent combines the wire clamping mechanism with the lamp holder bottom cover structure. The clamping blocks are formed as integral parts of the bottom cover, merging multiple functions (structural support and wire fixation) into a single integrated component, thereby reducing device complexity.
3Productivity
If a simplified structure is used without external screws, then assembly efficiency is improved, but wire fixation reliability may be compromised
Solution Approach 1:
The patent employs elastic clamping blocks that can deform elastically to grip the wire. The barb teeth on the clamping blocks provide a dynamic mechanical interlocking mechanism with the wire, ensuring reliable fixation through elastic deformation and geometric interlocking without requiring external screws.
Solution Approach 2:
The patent changes the physical parameters of the clamping blocks by making them elastic and providing specific geometric features (barb teeth). These parameter changes enable the clamping blocks to securely grip the wire through elastic deformation and mechanical interlocking, achieving reliable wire fixation without external fastening components.

AI summary
A lamp holder with fixed wire, characterized by comprising: a lamp holder bottom cover (10); a wire fixing device (20) installed inside the lamp holder bottom cover (10); and a base body (30) connected to the bottom end of the lamp holder bottom cover; wherein the lamp holder bottom cover (10) includes a lamp holder bottom cover body (11), the bottom surface of the lamp holder bottom cover body has a recess (13), the wire fixing device (20) is installed in the recess (13); wherein the wire fixing device (20) includes a base ring (21), an abutting part (22) extending downwardly from the opposite sides of a bottom surface of the base ring (21), a clamping block (23) arranged alternately and spaced apart from the abutting part (22) and a plurality of barb teeth (24) connected to the inner wall of each clamping block (23); the outer surface of the clamp block (23) is used to abut the inner wall of the recess (13); the thickness of the clamp block (23) gradually increases from the lamp holder bottom cover (10) to the base body (30), and the maximum distance between the bottom ends of the two clamp blocks (23) is greater than the inner diameter of the recess (13). The lamp holder's structure is simple and convenient to use. The fixing device is inserted into the main body of the lamp holder bottom cover. The outer surfaces of the two clamping blocks are in contact with the inner wall of the recess, and the two clamping blocks are compressed and close to each other to clamp wire. Under such scenario, the barb teeth abuts the wire, the clamping effect of the wire is enhanced, the wire is tightened, effectively prevent the wire from being pulled out, the installation procedure is simplified, and the assembly efficiency is effectively improved.
