Adjustable Rear Sight Assembly for Firearm Trajectory Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms with non-adjustable rear sight systems become increasingly difficult to accurately aim at distant targets due to the effects of gravity on bullet trajectory, requiring users to adjust their aim significantly, which complicates alignment with the target.
Innovation Solution
A rear sight assembly with a threaded thumb wheel and support member allows for adjustable height of the rear aiming point member, enabling users to modify the firearm's trajectory by rotating the thumb wheel, thereby compensating for varying distances and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If non-adjustable sights are used, then the firearm is simpler to manufacture and operate, but the aiming accuracy deteriorates at distant targets due to bullet drop
Solution Approach 1:
The patent implements an adjustable rear sight system where the rear aiming point member can be moved vertically along the sight assembly. This dynamic adjustment capability allows the sight to adapt to different shooting distances by compensating for bullet drop, thereby maintaining aiming accuracy without requiring a completely complex redesign of the entire firearm.
Solution Approach 2:
The patent changes the vertical position parameter of the rear aiming point member to compensate for bullet drop at different distances. By adjusting this parameter, the sight system maintains accuracy across varying ranges while keeping the overall structure relatively simple.
2Measurement precision
If adjustable sights are added to compensate for bullet drop, then aiming accuracy at distant targets improves, but the device complexity increases
Solution Approach 1:
The patent divides the sight assembly into distinct components: a rear sight base, a rear aiming point member, and an adjustment mechanism. This segmentation allows the adjustment function to be isolated to a specific component, reducing the complexity burden on the overall system while maintaining the desired accuracy improvement.
Solution Approach 2:
The rear aiming point member is nested within or integrated with the rear sight base structure. This nesting approach allows the adjustment mechanism to be compact and integrated rather than adding significant external complexity, achieving the dual goal of improved accuracy and controlled complexity.
