Rotating Bowstring Adjuster for Peep Sight Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archery bows, particularly compound bows, face challenges in maintaining synchronous cam rollover and proper peep sight alignment due to string and cable stretch, requiring frequent tuning and the use of a bow press for adjustments.
Innovation Solution
The development of a bowstring and cable adjuster system with rotatable elements that can be mounted directly to the bowstring and cables, allowing for adjustments in length and tension without disassembling the bow, and incorporating a peep sight for in-field alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional bow press adjustment method is used, then cam rollover synchronization can be achieved, but adjustment complexity and time consumption increase
Solution Approach 1:
The patent extracts the adjustment function from the complex bow press system and integrates it directly into the bowstring itself. The bowstring adjuster is a self-contained device that combines length adjustment, tension adjustment, and peep sight alignment functions into a single component mounted on the bowstring, eliminating the need for external bow press equipment.
Solution Approach 2:
The bowstring adjuster enables the archer to perform adjustments independently without requiring specialized equipment or technical expertise. The device includes intuitive adjustment mechanisms with indicators that allow the user to self-correct cam synchronization and peep sight alignment issues in the field.
2Reliability
If frequent tuning is performed to maintain proper bow performance, then shooting accuracy can be maintained, but time and effort requirements increase
Solution Approach 1:
The bowstring adjuster is pre-configured with indicators and adjustment mechanisms that guide the user through the tuning process. The device allows for quick visual assessment of bowstring length and peep sight alignment, enabling rapid adjustments without extensive measurement or calculation.
Solution Approach 2:
The adjuster device incorporates dynamic adjustment capabilities that allow for quick modification of bowstring length and peep sight orientation. The rotatable components and adjustable mechanisms enable the archer to adapt to changing conditions (string stretch, environmental factors) in minutes rather than hours.
3Measurement precision
If peep sight is mounted between bowstring strands, then proper alignment can be achieved, but rotation misalignment occurs due to string stretch
Solution Approach 1:
The peep sight is mounted on a rotatable carrier that can adjust its orientation independently of the bowstring's rotation. The device includes a locking mechanism that allows the peep sight to be positioned at the correct angle and then secured, preventing rotation even as the bowstring stretches or rotates during use.
Solution Approach 2:
The peep sight assembly is divided into separate functional components: the mounting carrier attached to the bowstring, the rotatable positioning mechanism, and the peep sight itself. This segmentation allows each component to perform its specific function - the carrier moves with the string, the mechanism compensates for rotation, and the peep sight maintains stable alignment.

AI summary
An archery bow adjuster includes first and second adjuster portions. The first portion is configured to mount to one of a bowstring and a cable. The second portion is configured to mount to the one of the bowstring and the cable. The first portion is rotatable relative to the second portion to adjust a length of the one of the bowstring and the cable of an archery bow.
