Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current archery equipment lacks precise visual indicators for alignment and aiming, leading to uncertainties in hitting the intended target, especially with single aperture peep sights that occlude the front sight fiber optic pin and lack clear centering verification.
Innovation Solution
The Optical Diffraction Alignment Lens, featuring a symmetric planar-array of multiple pin-hole apertures, forms a virtual aperture that presents a clear optical verification of alignment, eliminating the need for single aperture peep sights and providing unobstructed views for precise aiming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single aperture peep sight is used, then the device structure is simple, but the alignment precision is poor and the front sight fiber optic pin is occluded
Solution Approach 1:
The single aperture is segmented into multiple pin-hole apertures arranged in a symmetric planar array. This segmentation allows light from the fiber optic pin to pass through multiple small holes, creating a virtual aperture image that provides precise alignment verification without occluding the front sight, thereby resolving the contradiction between alignment precision and device simplicity.
Solution Approach 2:
A lens is introduced as an intermediary element to focus light from the fiber optic pin through the pin-hole apertures to form a virtual aperture image. This intermediary optical system enables precise alignment indication while maintaining a relatively simple overall device structure by leveraging optical principles rather than mechanical complexity.
2Loss of information
If a single aperture peep sight is used, then the device structure is simple, but the visual verification of alignment is unclear
Solution Approach 1:
The single aperture is divided into multiple pin-hole apertures that collectively form a virtual aperture image. This segmentation provides clear visual feedback for alignment verification by creating a defined image that indicates whether the archer is properly aligned with the target, eliminating the information loss associated with unclear alignment verification while avoiding complex device structures.
Solution Approach 2:
The optical system creates a virtual aperture image with distinct visual characteristics that provide clear alignment verification. The image formation through the pin-hole apertures and lens system produces a visually distinguishable pattern that clearly indicates alignment status, addressing the information clarity issue without requiring complex mechanical or electronic components.
3Area of moving object
If the aperture diameter is increased, then the field of view is improved, but the visual acuity and alignment precision decrease
Solution Approach 1:
The aperture is segmented into multiple small pin-hole apertures rather than using a single large aperture. This segmentation allows the system to provide a sufficient field of view through the array of holes while maintaining high alignment precision, as each small pin-hole acts as a precise optical reference point that does not sacrifice visual acuity for field of view.
Solution Approach 2:
The system transitions from a single two-dimensional aperture to a three-dimensional array of multiple pin-hole apertures with a lens. This dimensional change allows the system to simultaneously provide an adequate field of view through the spatial arrangement of multiple holes while maintaining precise alignment verification through the optical focusing capability of the lens system.

AI summary
The invention is an Optical Diffraction Alignment Lens, incorporating a symmetric planar-array of pin-hole apertures, installed in a split bowstring configuration replacing the conventional peep sight on a tuned compound bow with a front sight fiber optic pin, providing to the archer a virtual aperture through the fiber optic pin tip as a precise alignment and aiming system for the arrow flight path to target. The Optical Diffraction Alignment Lens, the center of which is positioned in the vertical plane centered on the arrow flight path and fixed relative to the arrow nock end, presents to the aiming eye of the archer, a well-defined virtual aperture image in the tip of the front fiber optic pin, as a centered point of alignment, that is centered by the archer in the line-of-sight which the archer aligns through the virtual aperture to the impact point on target.
