Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Handheld firearms face challenges in accurate sighting due to short sighting fields and environmental conditions, and existing target markers often affect balance and require professional modifications.

Innovation Solution

A target marker module with a light source and optical component is integrated within the recoil spring guide of a handgun, allowing for adjustable alignment and operation without external modifications, using a circuit board and leads to maintain fixed distances for precise aiming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If target markers are mounted externally on the firearm, then the user can see and align the sights more easily, but the firearm balance is affected and it becomes difficult to holster

Engineering Contradiction:

Improvesighting visibilityVSAvoidholstering difficulty

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The target marker module is nested within the recoil spring guide of the firearm, utilizing the existing internal space. This allows the light source to be positioned inside the firearm structure, providing sighting enhancement without adding external components that would interfere with holstering or balance.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Illumination intensity

If target markers are mounted externally on the firearm, then the user can see and align the sights more easily, but professional gunsmith modifications are required

Engineering Contradiction:

Improvesighting visibilityVSAvoidmodification complexity

Core Design Contradiction:

Illumination intensityVSEase of manufacture

Solution Approach 1:

The target marker module is designed as a universal component that can be installed in the recoil spring guide of various firearm types without requiring custom modifications. The module uses standard mounting interfaces and can be installed by the end user, eliminating the need for professional gunsmith services.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If internally-mounted target markers are used, then firearm balance is maintained, but alignment and focusing becomes difficult resulting in higher manufacturing cost

Engineering Contradiction:

Improvefirearm balanceVSAvoidalignment difficulty

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The target marker module incorporates adjustable alignment mechanisms that allow the light source and optical component to be positioned and focused after installation. This dynamic adjustment capability enables users to achieve proper alignment without requiring complex precision manufacturing, thereby reducing manufacturing costs while maintaining balance.

Inventive Principle:

Principle #15Dynamics

4Volume of moving object

If handheld firearm sights are placed close together, then the firearm structure is compact, but the sighting field becomes short making accurate aiming difficult

Engineering Contradiction:

Improvefirearm compactnessVSAvoidaiming accuracy

Core Design Contradiction:

Volume of moving objectVSMeasurement precision

Solution Approach 1:

The target marker introduces a new dimension to the sighting system by adding illumination and optical enhancement capabilities. This allows the existing compact sight arrangement to achieve improved aiming accuracy through enhanced visibility and target illumination, effectively compensating for the short sighting field without requiring the sights to be spaced farther apart.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
