Archery Bow Cable Guard Lateral Force Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery bows experience increased vibration and noise during shooting, which can be uncomfortable for archers and affect shooting performance.
Innovation Solution
The archery bow design incorporates a cable guard with a body portion and cable engaging portion that applies a lateral force to the cables, varying between brace and drawn conditions to reduce vibration and noise, and includes a vibration and noise suppressor to minimize oscillation and maintain cable tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional archery bows are used, then the bow structure is simple, but the bow produces increased vibration and noise during shooting
Solution Approach 1:
A cable guard is introduced as an intermediary component between the cable and the riser. The cable guard applies a lateral force to the cable that varies between brace and drawn conditions, serving as a mediator to reduce vibration and noise without requiring fundamental changes to the bow's core structure.
Solution Approach 2:
The cable guard is designed to provide dynamic lateral force that changes based on the bow's state (brace vs. drawn conditions). This dynamic adjustment allows the system to adapt to different shooting phases, reducing vibration and noise while maintaining structural simplicity.
2Stability of the object's composition
If cable tension is not controlled, then the bow structure is simpler, but oscillation increases reducing shooting performance
Solution Approach 1:
The cable guard acts as a mediator that indirectly controls cable tension through lateral force application. This approach maintains cable tension stability without requiring direct mechanical control mechanisms on the cable itself, thus avoiding increased complexity.
Solution Approach 2:
The cable guard changes the lateral position parameter of the cable dynamically between brace and drawn conditions. This parameter change allows the system to maintain optimal cable tension stability throughout the shooting process without adding complex control mechanisms.
3Object-affected harmful factors
If no cable lateral force is applied, then the cable guard structure is simpler, but vibration and noise increase
Solution Approach 1:
The cable guard applies lateral force at a specific local position on the cable rather than requiring a complex distributed system. This localized intervention effectively reduces vibration and noise while keeping the overall structure simple.
Solution Approach 2:
The cable guard modifies the lateral position parameter of the cable at a specific location. This localized parameter change is sufficient to reduce vibration and noise without requiring a complex overall structure.

AI summary
In some embodiments, an archery bow comprises a riser comprising a grip, a first limb and a second limb. A drawstring extends between the first limb and the second limb, for example extending between rotatable members supported by the limbs. A first cable, such as a power cable, also extends between the first limb and the second limb. A cable guard is attached to the riser, which comprises a body portion and a cable engaging portion. The cable guard biases a portion of the first cable in a direction away from the riser.
