Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED light strips in cables require a low-voltage power supply, making them unsuitable for use in environments like open-pit coal mines, and existing solutions with integrated coil and LED light strips are fragile, have poor tensile strength, and cannot withstand towing or moving, limiting their application to fixed installations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional LED light strip with magnetic conducting wire and lamp bead wire is used, then the cable contains light strip technology, but the power wire becomes thick and the cable outer diameter is greatly thickened making it bulkier
Solution Approach 1:
The patent combines the electromagnetic field energy collection wire core and the light strip into a single integrated structure. The light strip is directly installed on the wire core, eliminating the need for separate magnetic conducting wire and lamp bead wire layers. This merging reduces the overall cable diameter while maintaining the light strip functionality.
2Adaptability or versatility
If traditional LED light strip with magnetic conducting wire and lamp bead wire is used, then the cable contains light strip technology, but the light strip is fragile and the cable cannot withstand towing and moving
Solution Approach 1:
The patent employs a flexible protective sleeve made of soft material that completely wraps the light strip. This protective sleeve acts as a flexible shell that protects the fragile light strip from damage during towing and moving operations, while still allowing the light strip to function normally.
3Loss of time
If coil and LED light strip are integrated to generate electricity themselves, then the light strip can be lit without external power supply, but the electricity generated per unit time is small meeting only low-power lamp beads
Solution Approach 1:
The patent changes the parameters of the electromagnetic field energy collection wire core by increasing the number of coils and optimizing the coil winding density. This increases the electromagnetic induction efficiency and the electricity generated per unit time, enabling the system to power higher power light strips beyond just low-power lamp beads.
4Loss of time
If inductance core is welded to PCB to form light strip, then the light strip can be lit, but the light strip has poor tensile effect and bending resistance
Solution Approach 1:
The patent replaces the traditional rigid PCB welding structure with a flexible wire core-based structure. The electromagnetic field energy collection wire core and light strip are connected through flexible conductive materials rather than rigid welding to PCB, significantly improving the tensile strength and bending resistance of the light strip assembly.
