Riflescope Microdisplay Windage Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current riflescopes require manual calculations for aiming, which can lead to inaccuracies due to forgotten steps or miscounting windage corrections, especially for novice or rushed riflemen, and including too many windage aiming points can clutter the view and be impractical.
Innovation Solution
A sighting system with a set of lenses, a wind sensor, and a processor that calculates wind uncertainty and projects an aiming point onto the field of view through a microdisplay, allowing for automatic correction of aiming based on range, wind, and magnification settings without the need for manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple windage aiming points are included on the reticle, then windage correction capability is improved, but the field of view becomes cluttered and aiming difficulty increases
Solution Approach 1:
The patent extracts the windage correction markings from the physical reticle and relocates them to an external display device. This allows the reticle to remain clean and uncluttered while still providing comprehensive windage correction capabilities through the separate display interface.
Solution Approach 2:
The patent introduces an intermediary display device that acts as a mediator between the shooter and the windage correction information. This intermediary presents the correction data in a non-intrusive manner that does not obstruct the view through the reticle, solving the contradiction between providing detailed correction data and maintaining clear aiming visibility.
2Device complexity
If manual windage correction steps are required, then device complexity is reduced, but accuracy decreases due to human error
Solution Approach 1:
The patent implements a self-service system where the optical device automatically calculates and presents the correct windage correction based on input parameters. The system performs the correction calculations itself without requiring the user to manually compute or interpret complex data, thereby eliminating human error while maintaining operational simplicity.
Solution Approach 2:
The patent incorporates feedback mechanisms that automatically adjust the aiming point presentation based on windage parameters. The system receives windage data, processes it through ballistics calculations, and provides immediate visual feedback showing the corrected aiming point, ensuring accuracy without increasing user burden.
3Measurement precision
If addressable windage aiming points are implemented, then windage precision is improved, but device complexity increases due to conductor requirements
Solution Approach 1:
The patent replaces the mechanical/conductor-based addressable system with an electronic display system. Instead of using physical conductors to activate specific reticle elements, the system uses electronic rendering on a display device, which eliminates the need for complex conductor networks while maintaining precise windage indication capabilities.
