Solution Overview

Problem

Existing tactical lights mounted on firearms require the gun to be drawn for non-emergency situations, making them cumbersome and limiting the user's hand availability.

Innovation Solution

A hands-free flashlight assembly that can be mounted ergonomically on the back of a wearer's hand, allowing for adjustable positioning and enabling both hands to remain functional, with features such as a switch activation mechanism and optional laser integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If tactical lights are mounted on firearms for hands-free use, then hand availability is improved, but the firearm must be drawn in non-emergency situations which creates harm

Engineering Contradiction:
Improvehand availabilityVSAvoidunnecessary firearm exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The flashlight is extracted from the firearm and repositioned to be worn on the user's hand or wrist, separating the lighting function from the firearm. This allows the flashlight to be used hands-free without requiring the firearm to be drawn or visible, eliminating the harmful effect of unnecessary firearm exposure while maintaining hand availability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Illumination intensity

If traditional flashlights are held in hand, then lighting function is provided, but hand functionality is reduced

Engineering Contradiction:
Improvelighting functionVSAvoidhand functionality
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The flashlight is designed to be worn on the user's own hand or wrist, using the user's body to support and position the device. This self-service approach eliminates the need to actively hold the flashlight, providing continuous lighting while keeping the hand free to perform other functions such as gripping, manipulating objects, or maintaining readiness.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If flashlight is mounted on hand with multiple components, then functionality is improved, but device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flashlight assembly is designed with universal mounting capabilities that can accommodate different flashlight models and configurations. The mounting system includes adjustable components and universal attachment mechanisms that work with various flashlight sizes and shapes, providing versatile functionality without requiring complex customizations for each specific flashlight model.

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