Reflex Sight Dual Reticle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Short range projectile weapons, such as pistols and shotguns, experience significant bullet drop variation and uncertainty in projectile trajectory, making it difficult for shooters to accurately aim and estimate potential collateral damage due to limited sighting options.
Innovation Solution
A reflex sight with adjustable reticles that project multiple aiming points onto a collimating lens, allowing shooters to account for bullet drop and ordinance spread, enabling precise aiming and minimizing collateral damage by providing an indication of the angular area of impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single reticle position is used in the reflex sight, then the device complexity is reduced, but the adaptability to different ranges and bullet drop variations deteriorates
Solution Approach 1:
The single reticle is segmented into multiple distinct reticle positions (first reticle position and second reticle position), each optimized for different shooting ranges and bullet drop characteristics. This allows the sight to handle multiple ranging scenarios without requiring multiple complete sight units, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The reticle position is made dynamically adjustable through the actuation assembly, allowing the shooter to switch between different reticle positions based on the actual shooting range and conditions. This dynamic adjustment capability provides adaptability to varying ranges while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If multiple adjustable reticles are added to the reflex sight, then the adaptability to different ranges improves, but the device complexity increases
Solution Approach 1:
The reflex sight is designed with multi-functionality by incorporating multiple reticle positions within a single sight unit. The actuation assembly enables a single mechanism to control multiple reticle positions, making the device universal for different shooting scenarios without proportionally increasing complexity.
Solution Approach 2:
Multiple reticle positions and their adjustment mechanisms are merged into a single integrated actuation assembly. This consolidation allows the shooter to access multiple reticle configurations through one control interface, reducing the operational complexity that would otherwise result from having separate adjustment mechanisms for each reticle.
3Ease of operation
If reticle position is fixed, then the ease of operation is improved, but the measurement precision of bullet drop compensation deteriorates
Solution Approach 1:
Multiple reticle positions are pre-configured at specific elevations corresponding to different shooting ranges and bullet drop characteristics. The shooter can quickly select the appropriate pre-configured position without performing complex calculations or adjustments during the shooting moment, maintaining ease of operation while achieving precise bullet drop compensation.

AI summary
A reflex sight, having a mounting base that has an engagement element for attachment to a firearm. Also, a collimating front lens is mounted on the mounting base. A first reticle projection system projects a first reticle onto the front lens, at a first position, the first position being user adjustable, relative to the mounting base, by a first actuation assembly. In addition, a second reticle projection system, projecting a second reticle onto the front lens at a second position, the second position being user adjustable, relative to the first position by a second actuation assembly.
