Solution Overview

Problem

Reflex sight devices are cumbersome to use in daylight/sunlight due to interference from UV lights, which can hinder the visibility of the aiming mark, leading to potential miss-shooting.

Innovation Solution

A reflex sight device with a cover body and a detachable lens shield that blocks ultraviolet lights, reducing interference and enhancing visibility of the aiming mark.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the reflex sight is exposed under sunlight or high intensity daylight, then the user can operate the sight in outdoor conditions, but UV lights interfere with the aiming mark visibility

Engineering Contradiction:

Improveoutdoor operation capabilityVSAvoidUV light interference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A lens shield is introduced as an intermediary component between the sunlight and the reflective lens. The lens shield selectively blocks UV lights while allowing visible light to pass through, thereby mediating the harmful interaction between sunlight and the aiming mark visibility.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The lens shield converts the harmful UV light component of sunlight into a beneficial filtering action. By blocking UV lights that cause interference, the lens shield enhances the visibility of the aiming mark while still allowing the necessary visible light for outdoor operation.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Object-affected harmful factors

If a lens shield is added to block UV lights, then UV light interference is reduced, but the device structure becomes more complex

Engineering Contradiction:

ImproveUV light interferenceVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective function is segmented into a separate, detachable lens shield component rather than integrating UV filtering into the main sight body. This segmentation allows the lens shield to be added or removed as needed, reducing permanent structural complexity while maintaining the UV blocking capability when required.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lens shield is designed to be detachable and adjustable, allowing the user to dynamically configure the sight system based on lighting conditions. The lens shield can be attached when outdoor operation is needed and removed or adjusted when not needed, providing dynamic adaptability without permanent structural complexity.

Inventive Principle:

Principle #15Dynamics
