Optical Reflex Sight Frame with Shock-Absorbing Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reflex sights used in firearms and other instruments are prone to damage from impacts, scratches, and environmental contaminants, and can malfunction due to LED failures or battery issues, leading to operational disruptions.
Innovation Solution
The optical reflex sight features a frame with upstanding side walls and a top surface that includes cavities to absorb shock and protect the optical element, along with a removable hood for additional protection and an ambient light sensor to adjust illumination brightness, ensuring continued functionality under adverse conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the optical element is exposed to provide clear viewing, then the field of view is accessible, but the optical element is vulnerable to impact damage and environmental contaminants
Solution Approach 1:
The frame is divided into multiple protective zones including side walls, a top wall with cavities, and corner portions, each segment providing specific protection while maintaining optical access through the structured design
2Strength
If the frame structure is reinforced to protect the optical element, then impact resistance is improved, but the device complexity increases
Solution Approach 1:
The frame combines different materials with complementary properties: aluminum or aluminum alloy for structural strength, rubber or polymer fillers for shock absorption, and clear polymer for protective covering, creating a composite structure that achieves high impact resistance
Solution Approach 2:
The frame incorporates shock-absorbing cavities filled with rubber or polymer material positioned around the optical element, providing preemptive cushioning that absorbs impact energy before it reaches the optical component

AI summary
Optical sights for mounting on a firearm are provided, each of the sights having a base defining a barrel end and a rear end; a frame extending upwardly from the base at the barrel end and defining an opening; an optical element received in the opening; and an illumination device operable to display an aiming point on the optical element to generate said aiming point.
