Solution Overview

Problem

Existing devices designed to illuminate or mark objects in low-light conditions are not durable enough, often requiring frequent battery replacements or recharging, and lack secure attachment mechanisms and dark activation sensors, resulting in inefficient operation and limited visibility.

Innovation Solution

A compact, highly efficient Plural Spectrum Locator Lighting Device with a transparent housing and 360-degree visibility, featuring a dark activation sensor, cord lock, and secure attachment bracket, which can operate for over three weeks without recharging and provides both visible and non-visible spectrum illumination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing lighting devices are used to mark objects in low-light conditions, then visibility is provided, but the devices lack durability and require frequent battery replacements or recharging

Engineering Contradiction:

Improvedevice durabilityVSAvoidbattery operation duration

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent employs disposable lithium batteries that can be easily replaced, treating the power source as a consumable component. This allows the lighting device itself to remain durable and reusable while accepting that the battery will eventually deplete and need replacement, resolving the contradiction between device durability and battery operation duration.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If existing lighting devices operate continuously, then visibility is maintained, but energy is wasted during daytime when not needed

Engineering Contradiction:

Improvevisibility assuranceVSAvoidbattery energy consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The device incorporates a light-activated sensor that automatically controls the LED to turn on only during nighttime or low-light conditions and turn off during daytime. This periodic operation based on ambient light levels maintains visibility assurance when needed while preventing energy waste during unnecessary periods.

Inventive Principle:

Principle #19Periodic action

3Ease of operation

If existing devices lack secure attachment mechanisms, then they can be easily deployed, but they become loose or detached and limit visibility

Engineering Contradiction:

Improvedevice deploymentVSAvoidattachment security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The device uses a dynamic attachment system with an elastic band and cord lock mechanism that allows for easy adjustment and secure fastening to various objects like tents, vehicles, or trees. The elastic band provides flexibility for different sizes while the cord lock ensures secure attachment, resolving the contradiction between ease of deployment and attachment security.

Inventive Principle:

Principle #15Dynamics

4Device complexity

If existing devices provide only visible light, then they are simple in design, but they lack NVG (Night Vision Goggle) compatibility

Engineering Contradiction:

Improvelighting spectrumVSAvoidvisibility compatibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The device employs a dual-mode LED that can emit both visible light and infrared light. This allows the single device to serve multiple functions: providing visible illumination for naked eye visibility and emitting infrared light for NVG compatibility, thereby achieving versatility without significantly increasing device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
