Color Changing Light Chain Modular Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color changing light chains have complex production and assembly processes due to the need for multiple core wires, leading to inefficiencies and potential poor connections, making it difficult to replace damaged lighting modules and achieve stable color signal transmission.
Innovation Solution
A color changing light chain design using a power line group with a live wire, neutral wire, and signal wire, where the signal wire controls color changes through a controller, reducing the number of core wires and employing a screw-connected modular structure between lighting modules and lampholders for easier assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple core wires are used for RGB color control, then color changing function is achieved, but production complexity increases and assembly efficiency decreases
Solution Approach 1:
The patent combines multiple control functions into a single signal wire. Instead of using separate wires for red, green, and blue control, a single signal wire transmits encoded color information to the lighting module, which then decodes and executes the color changing commands. This merging approach maintains full RGB color control capability while dramatically reducing wire count and production complexity.
Solution Approach 2:
The patent introduces an encoder/decoder intermediary system. The encoder converts color control signals into a compact format transmitted through the single signal wire, and the decoder in the lighting module reconstructs the original color control commands. This intermediary mechanism enables complex color control functionality to be achieved through simplified wiring infrastructure.
2Adaptability or versatility
If multiple core wires are used for color control, then color changing function is achieved, but connection reliability deteriorates due to poor contact
Solution Approach 1:
By merging multiple control signals into a single signal wire, the patent eliminates multiple connection points that could potentially fail. The single wire connection reduces the number of solder joints and electrical contacts required, thereby improving overall connection reliability while maintaining full color control functionality through the encoded signal transmission.
3Device complexity
If integrated structure is used, then compact design is achieved, but repairability deteriorates when lighting module is damaged
Solution Approach 1:
The patent applies segmentation by separating the lighting module from the lampholder into distinct, independently replaceable components. The lighting module can be easily removed and replaced without affecting the lampholder or other parts of the system. This modular segmentation maintains a compact integrated appearance during normal operation while enabling simple field replacement of damaged lighting modules, directly addressing the repairability issue.
