Archery Release Length Adjuster With Offset Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery releases have limited length adjustment options due to identical hole spacing in multi-hole rigid adjusters, leading to a weak connection and restricted movement, which can result in an undesirable release body position, especially when not in use.
Innovation Solution
The archery release features a rigid length adjuster with offset holes in the sleeve and stem, allowing for precise adjustment and rotation about multiple axes, enabling infinite positioning and secure storage when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If identical hole spacing is used in sleeve and stem, then proper positioning is ensured, but the amount of overall length adjustment is limited
Solution Approach 1:
The patent applies asymmetry by using different hole spacing patterns in the sleeve versus the stem. The sleeve has holes spaced at a first pitch while the stem has holes spaced at a second pitch, where the pitches differ. This asymmetric hole spacing allows the fastener to engage different hole combinations, thereby increasing the overall length adjustment range while maintaining proper positioning through the threaded connection.
2Strength
If thin sleeves are used, then device complexity is reduced, but the connection between sleeve and stem becomes weak
Solution Approach 1:
The patent applies segmentation by dividing the adjustment mechanism into distinct functional components: the sleeve with its own hole pattern, the stem with its own hole pattern, and the fastener that engages both. This segmentation allows each component to be optimized independently - the sleeve can remain thin for low complexity while the threaded fastener provides the necessary connection strength through mechanical engagement with threaded holes in both the sleeve and stem.
3Ease of operation
If rigid attachment at pin is used, then structural stability is improved, but the release body cannot be precisely positioned according to archer's preference
Solution Approach 1:
The patent applies dynamics by making the release body positionable and adjustable rather than fixed. The length adjuster mechanism with multiple holes and a movable fastener allows the archer to dynamically adjust the distance between the release body and wrist strap to precise positions. The threaded connection provides stability when a position is selected, while the ability to move the fastener between holes provides adjustability.
4Adaptability or versatility
If rigid multi-hole adjuster is used, then manufacturing is simplified, but the release body is constrained to limited range of movement
Solution Approach 1:
The patent applies asymmetry in the hole spacing patterns to increase movement range. By having the sleeve holes spaced differently from the stem holes, the mechanism can achieve multiple discrete length adjustments beyond what identical spacing would allow. The threaded fastener moves between these asymmetrically spaced holes to achieve the desired range of motion while maintaining a relatively simple two-piece construction.

AI summary
An archery release including a release body, a wrist strap and a rigid length adjuster which enables multiple levels of adjustment to the distance between the wrist strap and the release body. The adjuster can be rotatable about two axes perpendicular to one another. The adjuster can include a connector that fixes the rotational orientation or the adjuster about the first axis. The adjuster can be rotated from an extended mode to a storage mode about the second axis. The adjuster can be further rotated about the first axis to engage an exterior contour of the adjuster against a ring associate with the wrist strap. This in turn arrests movement of the adjuster relative to the ring and strap, so the release body is in a stowed position proximate the wrist strap when the archery release is not in use. A method also is provided for operating an archery release.
