Bowstring Release Sear Mechanism for Adjustable Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bowstring releases do not effectively address bowstring release anticipation or anxiety, which can affect archery performance.
Innovation Solution
A bowstring release with a handle, jaw, and sear that emits a signal before releasing the bowstring, allowing adjustable rotation settings for precise release, and includes features like spring-biased jaws and adjustable thumb rest for user comfort and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional trigger mechanism is used for bowstring release, then the release mechanism is simple in structure, but the archer experiences anxiety and cannot accurately control the release timing
Solution Approach 1:
The sear mechanism is pre-configured with multiple detent positions that correspond to different release timing options. The archer selects and sets the desired release timing in advance by positioning the sear at the appropriate detent, allowing precise control of when the jaw will release the bowstring during the shot sequence.
Solution Approach 2:
The release mechanism transitions from a static trigger pull to a dynamic rotation-based system where the handle can be rotated to different positions. This dynamic adjustment allows the archer to control the release timing by rotating the handle to align the jaw with the desired release point in the sequence, eliminating anxiety through predictable, repeatable positioning.
2Reliability
If the jaw is spring-biased to automatically close and retain the bowstring, then the string retaining position is secure, but the trigger force required to open the jaw increases
Solution Approach 1:
The spring bias is pre-configured to automatically close the jaw and engage it with the sear at the appropriate detent position before the shot sequence begins. This preliminary action ensures the bowstring is securely retained in the designated position without requiring additional force from the archer during the shot.
Solution Approach 2:
The sear acts as an intermediary mechanism between the spring-biased jaw and the release trigger. The sear with its multiple detents mediates the force required to open the jaw, allowing the archer to control release timing by rotating the handle rather than directly overcoming the full spring bias force, thereby reducing the effective trigger force needed.
3Measurement precision
If multiple sear settings are provided for adjustable release timing, then the archer can control release timing precisely, but the device complexity increases
Solution Approach 1:
The sear mechanism is segmented into multiple discrete detent positions, each corresponding to a specific release timing option. This segmentation allows the archer to select precise release timing by positioning the sear at the appropriate detent, breaking down the continuous timing control into manageable, pre-defined intervals that are easy to select and reproduce.

AI summary
A bowstring release having a handle, a jaw, and a sear. The jaw is configured for drawing and releasing the bowstring. The sear includes a plurality of settings for adjusting the rotation of the handle at which the jaw releases the bowstring. While the bowstring is in the drawn configuration, the jaw and the sear are slidingly coupled and the jaw slides along a surface of the sear while the release is rotated. The bowstring is released when the jaw and the sear de-couple.
