Downlight Cover Plate Winding Structure Anti-Tensile Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing downlights face difficulties in assembly and disassembly due to loose connections between wires and the lamp body, leading to failures, and require complex installation processes with high precision and material costs.
Innovation Solution
A downlight design featuring a cover plate with winding structures and a deformable mounting member, where the electric wire is wound around these structures and a relief hole allows for compact anti-tensile structure and reduced material costs, with an elastic sheet for simplified installation that does not require precise mounting holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric wire is fixed using glue and pressure block, then the connection stability is improved, but the material cost and labor cost increase
Solution Approach 1:
The patent extracts the wire fixing function from the complex combination of glue and pressure block, implementing it through a dedicated wire groove structure integrated into the lamp body. This groove receives and secures the wire through mechanical confinement rather than requiring multiple separate components, thereby reducing material and labor costs while maintaining connection stability.
Solution Approach 2:
The patent merges the wire fixing function with the lamp body structure by integrating a wire groove directly into the lamp body housing. This consolidation eliminates the need for separate glue and pressure block components, reducing the number of parts and assembly steps while maintaining reliable wire connection.
2Reliability
If the lamp is installed using plastic or metal bayonet in mounting holes, then the installation stability is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent employs a deformable mounting member that can dynamically adapt to variations in mounting hole dimensions. The member deforms elastically during installation to accommodate holes that are too large or too small, then provides stable mechanical connection once installed, thereby reducing precision requirements while maintaining installation stability.
Solution Approach 2:
The mounting member utilizes elastic deformation to change its physical parameters (shape and size) during installation. By applying elastic theory, the member can deform to fit different hole sizes and then maintain a stable connection, converting the precision problem into a controllable deformation process.
3Ease of operation
If the electric wire runs a long distance inside the lamp body, then the connection flexibility is improved, but the space occupation increases
Solution Approach 1:
The patent segments the wire path into distinct functional zones: a wire groove for the main wire run and a separate wire entry hole for the connecting portion. This segmentation allows the wire to be routed efficiently through the lamp body while maintaining flexibility at the connection point, optimizing both space utilization and operational flexibility.

Function Achieved in This Case
The design enhances the stability of the anti-tensile structure, reduces material and labor costs, and allows for easier installation by reducing the need for precise mounting hole accuracy, as the elastic sheet deforms to fit within existing holes.
