Nested Annular Sight Ring for Peep Aperture Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archers face challenges in aligning the sight ring and peep aperture images due to variations in vision, stature, and ambient lighting conditions, with commercially available peep aperture sizes providing only approximate solutions, leading to difficulties in centering the images under different conditions.
Innovation Solution
An annular sight ring with nested, concentric, visually contrasting areas is introduced, allowing the archer to center a substantially circular border of at least one annular area within the peep aperture, ensuring image alignment regardless of varying field of view or ambient light conditions, by using a set of two or more annular contrasting areas on the rearward surface of the sight ring, which can be formed through stickers, paint, or other methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single sight ring with standard peep aperture is used, then the structure is simple and manufacturing is easy, but image alignment accuracy deteriorates under varying lighting conditions and for different archers
Solution Approach 1:
The sight ring is segmented into multiple concentric annular zones with alternating light and dark colors. Each zone provides a distinct visual reference that can be aligned with the peep aperture, allowing archers to select the most visible zone under different lighting conditions. This segmentation transforms a single uniform sight ring into a multi-functional alignment tool that maintains precision across varying environments.
2Adaptability or versatility
If peep aperture size is standardized, then manufacturing and inventory management are simplified, but adaptability to different archers' vision and stature deteriorates
Solution Approach 1:
The concentric annular zones transform a single standardized peep aperture into a multi-functional device that serves multiple archers with different vision requirements. Each archer can select the zone that provides optimal alignment visibility, making the standardized aperture adaptable to individual needs without requiring multiple aperture sizes. This universal design allows one size to fit all while maintaining precision.
3Measurement precision
If ambient lighting conditions vary, then outdoor shooting becomes more challenging, but the sight ring should maintain alignment accuracy across these conditions
Solution Approach 1:
The sight ring employs concentric annular zones with alternating light and dark colors (e.g., white and black) that create high visual contrast. This color alternation ensures that at least some zones remain clearly visible under varying ambient lighting conditions, whether bright sunlight, overcast skies, or dimmer indoor ranges. The contrasting colors enhance edge detection and alignment precision regardless of overall light levels.

AI summary
An archery sight includes an annular sight ring, one or more sight pins, and a set of two or more nested, annular, substantially concentric, visually contrasting areas on a rearward surface of the sight ring arranged substantially concentrically relative to the sight ring. One or more of the sight pins are visible through a central opening of an innermost annular colored area. With the bow held at full draw, the peep aperture and the central axis of the sight ring are substantially aligned along an intended sight line for the bow. Respective diameters of the peep aperture and the annular contrasting areas result, with an archer looking through the peep aperture along the intended sight line, in an observed image of a substantially circular border of at least one of the annular contrasting areas substantially coinciding with an observed image of the peep aperture.
