Archery Bow Cable Protector for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Archery bow cables and strings often wear down due to repeated contact with bow components, leading to reduced longevity and performance.
Innovation Solution
A protector is integrated into the archery bow design, supported by the cable segment to prevent contact between the cable and rotatable members, utilizing a tubular or roller design that can rotate and distribute wear, with anchoring mechanisms to maintain position and prevent translation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable is positioned directly adjacent to the rotatable member to reduce structural complexity, then the device complexity is reduced, but the cable surface suffers wear from repeated contact
Solution Approach 1:
A protector is introduced as an intermediary component between the cable and the rotatable member. The protector prevents direct contact between the cable and the rotatable member during the draw cycle, thereby eliminating wear on the cable while maintaining the compact structural arrangement.
2Reliability
If a protector is added to prevent cable contact with the rotatable member, then the cable longevity is improved, but the device complexity increases
Solution Approach 1:
The protector is designed as a thin-walled tubular structure that fits over the cable. This flexible shell design provides wear protection while minimizing the increase in structural complexity and maintaining a compact overall device configuration.
3Reliability
If the protector is designed to contact the rotatable member to distribute wear, then the cable integrity is maintained, but the friction increases
Solution Approach 1:
The protector serves as a mediator that contacts the rotatable member instead of the cable. This transfers the frictional interaction to the protector, which can be replaced or maintained without affecting cable performance, while the cable itself remains free from direct contact and wear.
