Coupled Power and Control Cable for Simpler Lighting Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems often require separate power and control cables, leading to complexity and confusion during installation, especially when multiple fixtures and control devices are involved.
Innovation Solution
A coupled power and control cable system that integrates a power cable and a control cable under a single overall jacket, featuring distinct indicators to differentiate between the two, simplifying installation by allowing a single cable to be pulled and connected to fixtures and control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power and control cables are used for LED lighting fixtures, then power transmission and control signal transmission can be achieved independently, but installation complexity increases and confusion occurs during installation and operation
Solution Approach 1:
The patent combines separate power cables and control cables into a single coupled cable assembly, where the power cable and control cable are mechanically coupled together. This merging reduces installation complexity by allowing both cables to be pulled and installed as one unit, while maintaining independent electrical functionality for power transmission and control signal transmission.
2Reliability
If separate power and control cables are used, then cable functions are distinct, but installation time and labor increase due to handling multiple cables
Solution Approach 1:
The coupled cable assembly merges power and control cables into a single installable unit, reducing installation time by eliminating the need to handle and pull separate cables independently. The mechanical coupling allows both cables to be installed simultaneously while maintaining clear functional distinction through physical separation within the assembly.
Solution Approach 2:
The coupled cable assembly segments the power cable and control cable as distinct components within the same assembly, allowing them to be pulled together but remain separately identifiable and connectable. This segmentation maintains functional distinction while enabling efficient joint installation.
3Reliability
If multiple cables are used for power and control, then electrical separation is maintained, but confusion occurs in environments with multiple fixtures and control devices
Solution Approach 1:
By coupling the power cable and control cable together in a fixed assembly, the invention ensures that operators always know which cables are paired together, eliminating confusion in environments with multiple fixtures. The mechanical coupling provides a consistent physical relationship that aids identification while maintaining electrical separation for reliable operation.

AI summary
Energy and a control signal may be provided using a coupled power and control cable. The coupled power and control cable may comprise a power cable, a control cable, and an overall jacket. The power cable may be connected between a switch and a fixture and may provide energy to the fixture from the switch. The control cable may be connected between the control circuit and the fixture and may provide the control signal to the fixture from the control circuit. The power cable and the control cable may be disposed beneath the overall jacket.
