Solution Overview

Problem

In environments like open-pit coal mines, cables with traditional LED light strips are often damaged due to lack of visibility at night, as they require an external power supply with unsuitable voltage, leading to waste and increased costs.

Innovation Solution

A cable with an LED light strip driven by an induced current, where a coil block generates an induced potential from an alternating magnetic field, powering the LED strip without an additional power supply, ensuring visibility and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a traditional LED light strip is used in a cable, then the cable can provide illumination at night, but an external power supply with suitable voltage is required which increases device complexity and may not be available in all environments

Engineering Contradiction:
ImproveLED light strip illuminationVSAvoidpower supply system
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The cable system generates its own power through electromagnetic induction. The power wire core acts as a primary coil that induces current in the coil block (secondary coil) when current flows through it, eliminating the need for external power supplies. The system serves itself by using the existing power transmission function to simultaneously generate illumination power.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The power transmission function and illumination function are merged into a single integrated system. The power wire core that transmits electrical energy also generates a magnetic field that induces current in the coil block, which then powers the LED light strip. This combines multiple functions (power transmission and illumination) into one unified structure without requiring separate power supplies.

Inventive Principle:
Principle #5Merging (Combining)

2Illumination intensity

If an external power supply is connected to the LED light strip, then the LED can be illuminated, but the voltage compatibility issue in open-pit coal mines leads to waste and increased costs

Engineering Contradiction:
ImproveLED light strip illuminationVSAvoidvoltage compatibility
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The system changes the voltage parameter dynamically through electromagnetic induction. Instead of requiring a fixed voltage input, the induced voltage in the coil block is generated proportionally to the current in the power wire core. This allows the LED light strip to adapt to different operating conditions and voltage levels automatically, solving the voltage compatibility problem in various environments.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the cable is laid without protection in open-pit coal mines, then the cable can move with equipment, but the cable is crushed and damaged at night due to lack of visibility

Engineering Contradiction:
Improvecable mobilityVSAvoidcable damage from crushing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cable incorporates an LED light strip that emits light, changing the visual appearance of the cable from invisible in darkness to brightly visible. This optical change makes the cable noticeable to operators and vehicles at night, preventing accidental crushing and damage while maintaining the cable's mobility and flexibility.

Inventive Principle:
Principle #32Color changes
