Archery Release Aid Trigger Mechanism with Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery release aids do not provide an optimal combination of precision, ease of use, and adjustable functionality, particularly in terms of trigger mechanisms and wrist support systems.
Innovation Solution
The proposed archery release aid features a trigger device with a pivotally mounted trigger and sear, a cocking spring for biasing the sear and trigger, a string hook with a reset spring, and a roller mechanism that allows for smooth bowstring release. Additionally, a C-shaped strap clamp secures the wrist strap to the trigger device, and a wrist support with a magnet holds the trigger device in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional trigger mechanism is used, then the release aid is simple and dependable, but the precision and consistency of the release are insufficient
Solution Approach 1:
The trigger mechanism is divided into separate functional components: a trigger lever for actuation, a sear for engagement and disengagement, and a roller for smooth release. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity and reliability.
Solution Approach 2:
The roller is configured to rotate during the release process, providing a dynamic element that ensures smooth and consistent bowstring release. This rotational movement enhances precision while maintaining the mechanical simplicity of the overall mechanism.
2Ease of operation
If a wrist trigger style release aid is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The wrist support, wrist strap clamp, and trigger device are merged into a single integrated unit. This combination provides the ease of operation of a wrist-trigger system while avoiding the complexity of separate components that would need to be assembled and coordinated.
3Adaptability or versatility
If adjustable functionality is added to the trigger mechanism, then adaptability is improved, but device complexity increases
Solution Approach 1:
The cocking spring is designed with adjustable tension, allowing users to modify the trigger pull weight according to their preferences or specific shooting conditions. This parameter adjustment provides adaptability while maintaining the mechanical simplicity of the spring-based system.

AI summary
An archery release aid is described. A trigger device for the archery release aid comprises a trigger pivotally mounted on a trigger pivot pin, the trigger movable between a cocked position and a fired position. A sear is pivotally mounted on a sear pivot pin and configured to interface with the trigger. A cocking spring is configured to bias the sear and the trigger in the cocked position. A string hook is pivotally mounted on a pivot pin. A reset spring is configured to bias the string hook in the cocked position. A roller is configured to rotate about its axis. In the cocked position the roller is retained between the sear and the string hook and in the fired position, the sear is rotated away from the roller, which allows the roller to translate and the string hook to release.
