Optical Intermediary for Day Sight Aimpoint Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical systems for standalone day sights struggle to maintain targets at long ranges within the field of view due to high bullet drop, requiring manual adjustments that change with varying target ranges, leading to inaccuracies and limitations in magnification.
Innovation Solution
An apparatus with an optical device and actuator that adjusts the angle of a light beam relative to the optical axis, allowing for external aimpoint corrections by receiving signals to control the angular deviation, enabling precise alignment and compensation for bullet drop without modifying the day scope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high magnification is used to view long range targets, then the target detail is improved, but the target falls outside the field of view due to bullet drop
Solution Approach 1:
The patent introduces an intermediary optical device (prism or mirror assembly) between the objective lens and the reticle that can be independently adjusted to compensate for bullet drop. This intermediary element allows the field of view to be effectively expanded vertically without changing the magnification power, enabling the operator to see both the high detail target and the adjusted aimpoint simultaneously.
Solution Approach 2:
The patent implements dynamic adjustment capability through an actuator mechanism that allows the optical intermediary to be repositioned during operation. The adjustable prism or mirror assembly can be dynamically oriented to different angles to compensate for varying bullet drop at different ranges, transforming a static optical system into a dynamically adaptable one that maintains field of view while preserving magnification detail.
2Measurement precision
If manual adjustment is used to correct aimpoint, then the aimpoint accuracy is improved, but the adjustment frequency increases with varying target ranges
Solution Approach 1:
The patent incorporates a feedback mechanism where the actuator receives input signals (manual or automated) based on the observed deviation and automatically adjusts the optical intermediary to correct the aimpoint. This closed-loop feedback system eliminates the need for repeated manual adjustments by continuously compensating for bullet drop as the operator observes the target and reticle alignment.
Solution Approach 2:
The optical adjustment system is designed to self-correct aimpoint deviations through an automated actuator mechanism that responds to observed errors. The system serves itself by automatically detecting and correcting bullet drop effects without requiring continuous operator intervention, reducing adjustment frequency while maintaining accuracy across varying ranges.
3Measurement precision
If the day scope is modified to compensate for bullet drop, then the aimpoint correction is improved, but the device complexity increases
Solution Approach 1:
The patent segments the optical correction function from the main day scope by using a separate, independently adjustable optical intermediary device. This segmented approach allows the correction mechanism to be added as a modular component that interfaces with the existing scope through mounting brackets, rather than requiring complex integration or modification of the scope's fundamental optical path, thereby reducing overall device complexity.
Solution Approach 2:
The patent uses an intermediary optical assembly (prism or mirror) as a mediator between the scope's objective lens and the reticle. This intermediary component handles the bullet drop compensation function, allowing the day scope itself to remain relatively simple while the correction is achieved through the added intermediary element that can be independently adjusted and positioned.
