Shooting Sports Sight Stray Light Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery and shooting sports sighting systems face accuracy issues due to unwanted stray light entering the field of view, which is exacerbated by changing lighting conditions, causing the point of impact to shift and affecting precision.
Innovation Solution
A shooting sports sight apparatus featuring a series of concentric rings within a sight housing that inhibits stray light by bouncing it away from the line of sight, with an interchangeable final baffle to optimize the aiming sight picture, preventing photons from entering the observable scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional sight housing is used without light management features, then the device complexity is low, but stray light enters the field of view causing accuracy to deteriorate
Solution Approach 1:
The sight housing is segmented into multiple functional zones using concentric rings and baffles. These segments divide the internal space to control light paths separately, with each ring and baffle serving as an independent light management element that blocks stray light while maintaining optical clarity for the intended field of view.
Solution Approach 2:
Concentric rings and baffles are introduced as intermediary elements between the external environment and the field of view. These intermediaries intercept and redirect stray light before it can reach the observer's eye, acting as mediators that filter unwanted light while allowing desired light paths to pass through.
2Adaptability or versatility
If lighting conditions change in the outdoor environment, then the adaptability of the sighting system to different environments is improved, but stray light angle changes cause accuracy to deteriorate
Solution Approach 1:
The sight housing incorporates adjustable components including interchangeable baffles and rings that can be configured based on lighting conditions. The system dynamically adapts to different outdoor lighting scenarios by allowing the observer to select appropriate baffle configurations that optimize performance for specific sun angles and light intensities.
Solution Approach 2:
The system changes physical parameters of light management by swapping baffles and rings with different geometries, apertures, and positions. Each configuration is optimized for specific lighting conditions, allowing the observer to adjust the optical parameters of the sight housing to match environmental conditions and maintain accuracy.
3Ease of operation
If the peep aperture is made larger to improve field of view, then the ease of operation is improved, but more stray light enters causing accuracy to deteriorate
Solution Approach 1:
The concentric rings and baffles create zones of different light management properties within the sight housing. The peep aperture area maintains larger opening for ease of use, while surrounding areas incorporate light-blocking structures with specific geometries designed to intercept stray light at different angles, allowing each zone to serve its specific function optimally.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively eliminates stray light, enhancing the accuracy of the sighting system by preventing light noise from contaminating the image scene, ensuring a clear and precise aiming experience across varying lighting conditions.
Implementation Method 1
At least one concentric ring provides a surface for stray light photons entering the first end of the sight housing to bounce in directions generally away from the line of sight

AI summary
A shooting sports sight apparatus to inhibit unwanted stray light of an observable scene. An example apparatus comprises a sight housing having a first end, a second end, an outer surface, and an inner surface. At least one concentric ring is positioned between the first end and the second end. At least one annular groove is defined between the first end of the sight housing and the concentric ring. The concentric ring provides a surface for stray light photons entering the first end of the sight housing to bounce in directions generally away from the line of sight into the annular groove, thereby inhibiting the stray light photons from entering field of regard (FOR) photons reaching the aft end of the sight housing which make up the observable scene where the second end has means for changing the baffle aperture diameter forming the final light baffle of the baffle assembly.
