Archery Release Offset Jaw Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixed jaw archery releases cause 'bowstring fighting the gap' issues, leading to increased trigger sensitivity and erratic arrow flight due to the parallel alignment of jaw surfaces, which results in additional force required for trigger actuation and premature bowstring wear.
Innovation Solution
The archery release design features a fixed jaw and movable jaw with surfaces offset at a predetermined angle from the longitudinal axis, minimizing contact and interference during bowstring release, thereby reducing trigger jerk and improving arrow flight consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fixed jaw and movable jaw surfaces are aligned parallel to the longitudinal axis, then the release structure is simple and easy to manufacture, but the bowstring fights the gap causing increased trigger force requirement and trigger jerk
Solution Approach 1:
The patent applies asymmetry by offsetting the fixed jaw and movable jaw surfaces from parallel alignment with the longitudinal axis by a predetermined angle (0.1° to 30°). This asymmetric configuration prevents the bowstring from fighting the gap during trigger actuation, eliminating trigger jerk while maintaining manufacturing simplicity through straightforward angular positioning of jaw surfaces.
Solution Approach 2:
The patent changes the geometric parameter of jaw surface orientation from parallel (0°) to offset by a predetermined angle (0.1° to 30°) relative to the longitudinal axis. This parameter modification resolves the contradiction by allowing smooth trigger actuation without increasing manufacturing complexity, as the angular offset can be easily incorporated into jaw fabrication.
2Device complexity
If the fixed jaw surface is aligned parallel to the longitudinal axis, then the release structure is straightforward, but the bowstring prematurely wears where it engages the gap
Solution Approach 1:
The asymmetric offset of jaw surfaces (0.1° to 30° from parallel alignment) redistributes the contact points between the bowstring and jaw surfaces. This prevents concentrated wear at the gap edge by creating a more favorable contact geometry, thereby extending bowstring service life while maintaining straightforward release structure design.
Solution Approach 2:
By modifying the jaw surface orientation parameter from parallel to offset by a predetermined angle, the patent changes the wear pattern on the bowstring. This parameter change eliminates premature wear at the gap engagement point while keeping the overall release structure simple and easy to manufacture.
3Device complexity
If the movable jaw forward portion is aligned parallel to the longitudinal axis, then the jaw configuration is simple, but it obstructs the forward path of the bowstring causing erratic arrow flight
Solution Approach 1:
The patent applies asymmetry by offsetting the movable jaw forward portion (relative to the bowstring notch) from parallel alignment with the longitudinal axis by a predetermined angle. This asymmetric positioning removes the obstruction in the bowstring's forward path, preventing erratic arrow flight while maintaining simple jaw configuration through straightforward angular positioning.
Solution Approach 2:
The patent changes the orientation parameter of the movable jaw forward portion from parallel (0°) to offset by a predetermined angle (0.1° to 30°) relative to the longitudinal axis. This parameter modification eliminates the obstruction effect on bowstring travel, ensuring consistent arrow flight without increasing jaw configuration complexity.
4Reliability
If the fixed jaw and movable jaw are positioned to capture the bowstring effectively, then the release holds the bowstring securely, but additional force is required to actuate the trigger mechanism
Solution Approach 1:
The asymmetric offset of jaw surfaces (0.1° to 30° from parallel alignment) creates a more favorable mechanical advantage in the trigger mechanism. This configuration reduces the additional force required to actuate the trigger while maintaining secure bowstring capture, as the offset geometry reduces friction and resistance during jaw opening.
Solution Approach 2:
By modifying the jaw surface orientation parameter from parallel to offset by a predetermined angle, the patent reduces the force required for trigger actuation. This parameter change maintains reliable bowstring holding security while decreasing the additional force needed to overcome gap friction during release.

AI summary
An archery release including a release body having a longitudinal axis, a fixed jaw having a bowstring facing surface being offset at a first predetermined angle from the longitudinal axis, and a movable jaw. The moveable jaw can define a bowstring notch, and can include a surface forward of the notch which opposes the fixed jaw. The moveable jaw surface can be offset at a second predetermined angle from the longitudinal axis, and can be substantially parallel to and oppose the bowstring facing surface when the moveable jaw is in a closed position. The first predetermined angle and/or the second predetermined angle can be about 0.1° to about 30°, about 0.1° to about 5°, or about 3° offset from the longitudinal axis. A method also is provided for drawing and releasing a bowstring with the assistance of the release.
