Solution Overview

Problem

Modern reflex sights have complex positioning apparatuses that require tight manufacturing tolerances, are prone to wear and breakage, and can be affected by shocks, leading to non-linear travel, dead clicks, and inconsistency in resolution during adjustments.

Innovation Solution

An adjustable target sight with a carrier plate and carrier mount system that allows for horizontal and vertical adjustments of the illumination device using pins and apertures, bias springs, and camming or sliding mechanisms to stabilize and precisely position the aiming dot, reducing mechanical complexity and enhancing durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional threaded adjusters with elongated tubes are used for positioning the light source, then the sight can be adjusted for targets at various distances, but the apparatus becomes complex, requires tight manufacturing tolerances, and is prone to wear and breakage

Engineering Contradiction:

Improveadjustment capability for various distancesVSAvoidcomplexity of positioning apparatus

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment mechanism is divided into separate functional components: a rotatable member with angular positions, a carrier member with apertures, and a light source holder. This segmentation allows each component to perform a specific function (rotation, positioning, light emission) independently, simplifying the overall design while maintaining adjustment capability for various distances

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces traditional threaded mechanical adjusters with a cam-based mechanism. The cam profile converts rotational motion into precise linear displacement of the light source, eliminating the need for threaded components and reducing mechanical complexity while maintaining adjustability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If traditional threaded adjusters with elongated tubes are used for positioning the light source, then the sight can be adjusted for targets at various distances, but the apparatus is subject to wear and breakage and can be affected by shocks

Engineering Contradiction:

Improveadjustment capability for various distancesVSAvoiddurability against wear and shock

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The cam mechanism is designed with inherent shock absorption capabilities through its profile geometry and material selection. The cam and follower interface is engineered to distribute loads and absorb sudden shocks from drops or impacts, protecting the light source and adjustment mechanism from damage while maintaining adjustment functionality

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent eliminates traditional threaded adjusters that are prone to wear and dislodgement by replacing them with a cam-based positioning system. The cam mechanism provides positive positioning without threaded connections, significantly improving reliability against wear and shock while maintaining adjustability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If traditional threaded adjusters are used for positioning the light source, then the sight can be adjusted, but non-linear travel, dead clicks, and inconsistency in resolution per revolution occur

Engineering Contradiction:

Improveadjustability of light positionVSAvoidconsistency of resolution per revolution

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The cam profile is designed with specific curvature characteristics to convert rotational motion into linear displacement. The cam geometry is engineered to provide linear or near-linear travel of the light source throughout the adjustment range, eliminating dead clicks and ensuring consistent resolution per revolution while maintaining ease of operation

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent replaces traditional threaded adjusters with a cam-based mechanism that provides more consistent and predictable positioning. The cam profile can be precisely engineered to eliminate non-linear travel and dead clicks, ensuring uniform resolution throughout the adjustment range while maintaining ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
