Compound Bow Cable Adjustment Assembly for Cam Timing Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The synchronization of cams in a compound bow is critical for optimal performance, but existing systems lack effective mechanisms to adjust and maintain proper timing, leading to degraded performance when synchronization is off.
Innovation Solution
A cable adjustment assembly with a lockable mechanism that allows for adjustable length of cable segments, enabling precise adjustment of cam timing by twisting and locking the cable segments relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable length is fixed, then manufacturing is simple, but cam timing synchronization cannot be adjusted leading to degraded performance
Solution Approach 1:
The cable system transitions from a fixed length to an adjustable length mechanism. The cable can be twisted and locked at different positions to change its effective length, allowing dynamic adjustment of cam timing synchronization while maintaining structural simplicity through a lockable mechanism.
Solution Approach 2:
The cable length parameter is made variable through a adjustment assembly that allows the cable to be twisted and locked at different positions. This changes the effective length of the cable to adjust cam timing, transforming a fixed parameter into an adjustable one to achieve proper synchronization.
2Reliability
If cam timing is not synchronized, then performance is degraded, but existing systems lack adjustment mechanisms
Solution Approach 1:
The adjustment assembly allows the user to independently adjust cable length and lock it in position without requiring additional tools or complex procedures. The mechanism serves itself by providing both the adjustment capability and the locking function in an integrated manner that is easy to operate.
Solution Approach 2:
The system provides dynamic adjustability for cam timing through a simple lockable mechanism. The cable can be easily twisted to change length and then locked to maintain the adjusted position, making cam timing synchronization accessible and easy to perform.
3Measurement precision
If cable segments are adjustable, then cam timing precision is improved, but device complexity increases
Solution Approach 1:
The cable length parameter is made variable through an adjustment assembly that allows precise control of cable length by twisting and locking at different positions. This enables precise adjustment of cam timing synchronization while maintaining relatively simple device architecture.
Solution Approach 2:
The cable is divided into adjustable segments that can be independently controlled in length. The adjustment assembly allows different cable segments to be tuned to achieve precise cam timing synchronization, with each segment's length being independently adjustable and lockable.

AI summary
A compound bow includes a cable assembly including an adjustment assembly. The adjustment assembly has a first unit and a second unit on a rotational axis of the cable assembly. A first cable segment has a terminal end rotationally fixed to the first unit. A second cable segment has a terminal end rotationally fixed to the second unit. The adjustment assembly includes a lock between the first unit and the second unit. The lock is movable between a locked position and an unlocked position. The first unit and the second unit are rotatable relative to each other about the rotational axis R of the adjustment assembly when the lock is in the unlocked position. The first unit and the second unit are fixed relative to each other about the rotational axis of the adjustment assembly when the lock is in the locked position.
