Trifurcated Cable Slider for Archery Bow Cam Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compound archery bow cable sliders cause dislocation of cable crossing from the bow centerline during the draw cycle, affecting cam timing and synchronization due to forced axial separation of power cables.
Innovation Solution
A trifurcated unitary cable slider design with an L-shaped and straight slot configuration allows power cables to maintain alignment with the bow centerline by enabling independent axial movement, preventing dislocation and ensuring constant cable angle with respect to pulleys throughout the draw cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cable slider fixes the cables in a spaced apart condition, then the cables are maintained separated from one another, but the cable crossing dislocates away from the bow centerline affecting cam timing
Solution Approach 1:
The cable slider is designed with a curved slot instead of a straight slot, allowing the cables to move dynamically along the curved path. This enables the cables to maintain proper spacing while their crossing point remains aligned with the bow centerline throughout the draw cycle, resolving the contradiction between stable cable spacing and precise cam timing
Solution Approach 2:
The curved slot geometry changes the positional parameters of the cables during movement. By designing the slot with specific curvature, the cable positions are adjusted dynamically to maintain both separation and centerline alignment, achieving both spacing stability and timing precision
2Reliability
If the cable slider restrains power cables between limits preventing contact, then cable separation is maintained, but cable crossing location moves during draw cycle
Solution Approach 1:
The curved slot enables dynamic cable positioning that adapts to the draw cycle. The cables are restrained to move only along the curved path, maintaining separation while allowing the crossing point to remain fixed at the centerline, thus achieving both reliable separation and precise crossing position
3Stability of the object's composition
If a unitary cable slider with fixed cable slots is used, then cable spacing is maintained, but the structure adds complexity to the slider design
Solution Approach 1:
The slider body is segmented into functional zones: a curved slot for cable movement, lateral walls for spacing, and a mounting portion for attachment. This segmentation allows each element to perform its specific function efficiently, maintaining cable spacing stability while keeping the overall structure relatively simple and manufacturable

AI summary
An archery bow cable slider includes a forward wall extending away from a base wall, a bifurcated wall extending away from the base wall including a rearward wall extending away from the base wall and an intermediate wall extending away from the rearward wall, and a throughbore extending through free ends of the forward, rearward, and intermediate walls. The base, forward, rearward, and intermediate walls establish a first slot having a laterally extending portion and an axially extending portion that extends substantially perpendicular to the laterally extending portion, and the rearward and intermediate walls establish a second slot that at least partially axially overlaps the first slot.
