Archery Hook Engager with Pivot and Gap for Sensitivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery release aids suffer from high frictional and vibrational feedback, lack micro adjustability, and safety features, leading to reduced sensitivity and action rate in releasing the bowstring.
Innovation Solution
The archery hook engager includes a bias interface portion, a pivotally coupled hook, and a motion portion with a gap to facilitate disengagement from the bowstring, along with a safety assembly that prevents unintentional releases, allowing for adjustable release points and reduced frictional feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hook is fixed rigidly to the carriage, then the structural strength is improved, but the sensitivity and rate of action of the release mechanism deteriorates
Solution Approach 1:
The hook is made pivotally coupled to the carriage instead of being rigidly fixed, allowing it to rotate freely about a pivot axis. This dynamic coupling enables the hook to move independently relative to the carriage during firing, improving sensitivity and rate of action while maintaining structural integrity through the pivot connection.
2Device complexity
If the sear position is fixed relative to the body, then the device complexity is reduced, but the micro adjustability for release point deteriorates
Solution Approach 1:
The sear is made movable relative to the body through a spring-loaded mechanism, allowing it to move in response to forces applied during setup and firing. This dynamic positioning enables micro-adjustability of the release point without requiring complex adjustment mechanisms, as the spring allows natural movement to fine-tune the sear position.
3Stability of the object's composition
If the pawl is locked in position during firing, then the stability of the mechanism is improved, but the frictional feedback and interference force increase
Solution Approach 1:
The harmful frictional engagement between the pawl and hook sear is eliminated by removing the pawl's locking function during firing. The pawl is designed to disengage from the hook sear when firing forces are applied, extracting the source of frictional feedback and interference forces while maintaining structural stability through the carriage and body framework.
Solution Approach 2:
The pawl is designed with dynamic movement capability, allowing it to rotate about its pivot and disengage from the hook sear during firing. This dynamic behavior reduces frictional feedback by allowing the pawl to move freely rather than maintaining rigid contact, while still providing stability when engaged during setup and non-firing conditions.
4Manufacturing precision
If the motion portion is tightly fitted to the stopper, then the manufacturing precision is improved, but the sensitivity and responsiveness of the release mechanism deteriorates
Solution Approach 1:
The motion portion is designed with intentional clearance relative to the stopper, allowing it to move freely within the defined space during firing operations. This dynamic clearance enables the motion portion to respond sensitively to firing forces without being constrained by tight tolerances, improving responsiveness while maintaining adequate manufacturing precision for proper alignment and function.

AI summary
An archery hook engager includes, in an embodiment, a first portion defining a first opening configured to receive a pivot member of an archery release device. The archery release device has a body, a carriage, and a hook pivotally coupled to the carriage. The pivot member is coupled to the carriage. The archery hook engager also includes a second portion configured to define a second opening that has an opening dimension. The second opening is configured to receive a stopper that is coupled to the body. The stopper includes a stopper dimension. There is difference between the opening dimension and the stopper dimension that results in a gap between the second portion and the stopper. Furthermore, the archery hook engager includes a hook interface portion configured to be engaged with a hook engagement portion of the hook.
