Back Tension Archery Release Aid with Magnetic Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archers experience target panic due to the traditional two-stage process of drawing and releasing the bowstring, which can be exacerbated by the use of caliper or trigger-style releases, and there is a need for a back tension style release aid that minimizes unintentional releases and provides a smooth firing mechanism.
Innovation Solution
A back tension style release aid with a handle and release lever system that includes a magnetic attraction force and a spring pin mechanism, allowing manual rotation to release the bowstring, featuring a hook piece that automatically resets after release, and adjustable set screws for personalized fit and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional two-stage process with trigger or caliper release is used, then the archer can draw and release the bowstring, but the archer experiences target panic and unintentional releases
Solution Approach 1:
The patent replaces the traditional mechanical trigger or caliper release system with a magnetic field-based release mechanism. Magnets are positioned to create an attractive force that holds the release lever in the drawn position, and when the trigger is pulled, the magnetic holding force is overcome, allowing smooth release. This substitution eliminates the jerky mechanical engagement of traditional systems, reducing target panic and unintentional releases while maintaining operational reliability.
2Reliability
If a caliper or trigger style release is used, then the bowstring can be released, but the release mechanism may release unintentionally
Solution Approach 1:
The patent introduces a magnetic field as an intermediary force between the release lever and the trigger mechanism. The magnets create a holding force that prevents unintentional release during the draw phase, while still allowing controlled release when the trigger is deliberately pulled. This magnetic intermediary adds reliability without significantly increasing mechanical complexity, as the magnetic field acts as a non-contact holding mechanism.
3Reliability
If a back tension release with manual rotation is used, then target panic is reduced, but the release head assembly requires complex rotation mechanisms
Solution Approach 1:
The patent simplifies the back tension release mechanism by replacing complex rotational locking mechanisms with a magnetic field-based holding system. The magnets maintain the drawn position without requiring complex mechanical interlocks, and the trigger mechanism directly overcomes the magnetic force for release. This substitution maintains the target panic reduction benefits of back tension releases while significantly reducing the complexity of the release head assembly.

AI summary
A back tension archery release aid including a rotatable safety release lever. The safety release lever is engaged and operated by the outer fingers of an archer. Once an archer achieves full draw, the release lever is operated by the archer's outer fingers to lock a portion of a release head assembly in place. Further rotation of the release releases the bowstring and fires an arrow. Certain back tension release aid embodiments include magnets which assist in holding a sear and bridge together within the release head assembly prior to releasing an arrow and assist in resetting the release after an arrow is released.
