Underground Lighting System with Visual Emergency Signaling

Solution Overview

Problem

Underground mining operations face challenges in providing adequate lighting and effective communication due to dynamic environments, dust, confined spaces, and low visual contrasts, leading to difficulties in maintaining safety and efficiently conveying emergency information.

Innovation Solution

A lighting system comprising a base station with interconnected light modules and sensors that continuously monitor environmental conditions, activating visual signals for emergency situations and providing guidance to safe zones, while also serving as a communication tool to direct personnel away from hazardous areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional communication means (email, printed notices, radios, sirens) are used in underground mining operations, then information can be transmitted to miners, but the communication is easily overlooked, misheard or not heard at all due to local operational noises and distractions

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional acoustic communication means (radios, sirens) with optical communication through the lighting system. The lighting modules can display text messages, symbols, and patterns that are visually perceivable regardless of operational noises, substituting acoustic information transmission with optical information transmission.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The lighting system uses different colors and patterns of light to convey different types of information and emergency conditions. Visual signals through color changes provide clear, distinguishable communication that is not affected by noise, allowing miners to quickly understand the nature and urgency of situations.

Inventive Principle:
Principle #32Color changes

2Loss of information

If emergency communication means are heard, then miners receive emergency information, but they easily become disorientated when evacuating due to the dynamic environment and low light conditions

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSIllumination intensity

Solution Approach 1:

The lighting system serves dual functions: providing general illumination for safe working conditions and delivering emergency communication information. The same light modules that illuminate the environment can also display emergency messages, evacuation directions, and safety information, eliminating the need for separate communication devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The lighting system acts as an intermediary that simultaneously provides illumination and information transmission. By using the existing light infrastructure for both purposes, the system ensures that miners receive clear visual information while maintaining adequate lighting levels for safe evacuation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If fixed light modules are sparsely used to reduce cost, then installation cost is reduced, but adequate lighting cannot be provided in the dynamic underground environment

Engineering Contradiction:
Core Design Contradiction:
Ease of manufactureVSIllumination intensity

Solution Approach 1:

The lighting system is divided into multiple independent light modules that can be distributed along the passageway at optimized intervals. Each module operates independently and can be controlled individually, allowing flexible placement to ensure adequate coverage while minimizing total number of modules required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates sensors and controllers that dynamically adjust lighting based on environmental conditions, miner presence, and operational needs. This dynamic control allows the system to provide adequate lighting only when and where needed, reducing overall energy consumption and allowing for more economical module placement.

Inventive Principle:
Principle #15Dynamics

4Loss of information

If non-emergency communications are disseminated through normal communication means, then information can be transmitted, but the information quickly becomes dated due to the rapidly changing dynamic environment

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The lighting system incorporates sensors that continuously monitor environmental conditions and can update displayed information in real-time. This feedback mechanism ensures that information displayed to miners remains current and accurate, automatically reflecting changes in the dynamic underground environment without requiring manual updates.

Inventive Principle:
Principle #23Feedback
