Firearm Sight Cover with Detachable UV Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective covers for sighting devices are cumbersome and insecure, especially when exposed to sunlight, as they interfere with the aiming mark due to UV light interference and often fall off during use.
Innovation Solution
A protective cover with a couplable cover body and detachable lens shield that securely locks onto the sighting device, featuring a housing portion, locking units, and an adjustable light source configuration to block UV light interference while allowing aiming through a vision opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is used to cover the sighting device, then the sighting device is protected from damage, but the aiming function cannot be performed and the cover easily falls off
Solution Approach 1:
The protective cover is divided into two functional parts: a cover body for protection and a detachable lens shield for UV light blocking. The lens shield can be removed when aiming is needed, separating the protection function from the aiming function while allowing both to coexist.
Solution Approach 2:
The lens shield acts as an intermediary element between the cover body and the lens. It provides UV light protection when attached and can be detached when full visibility is needed, mediating between protection requirements and aiming requirements.
2Reliability
If a protective cover is used to cover the sighting device, then the sighting device is protected, but the cover is insecure and falls down during use
Solution Approach 1:
The cover incorporates adjustable locking units that can dynamically adapt to different sighting device positions and shapes. The locking units can be adjusted to engage with various parts of the sighting device, providing stable attachment while allowing for different configurations.
3Object-affected harmful factors
If the protective cover blocks UV light, then UV interference is reduced, but the aiming mark visibility is also reduced
Solution Approach 1:
The lens shield is designed with selective optical properties - it blocks UV light wavelengths while allowing visible light wavelengths to pass through. This local quality differentiation allows UV protection without compromising aiming mark visibility in the visible spectrum.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides secure coverage for sighting devices, reduces UV light interference, and maintains aiming functionality, ensuring accurate shooting even in daylight conditions.
Implementation Method 1
a lens shield configured to be covered on a reflective lens of the sighting device to block or reduce the interference generated from the UV lights with the light source generated from the sighting device
