Archery Bow Limb Bedding with Adhesive Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery bows experience limb shifting in limb pockets, leading to accuracy issues and changes in bow performance when reassembled, due to lack of secure fitment between the bow limbs and the limb pockets.
Innovation Solution
A bow limb retaining assembly that uses a retainer with adhesive composition between the limb pocket and bow limb, ensuring a custom fit and restricting lateral or pivoting movement, thereby maintaining the original configuration during disassembly and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a limb pocket is used to attach the bow limb to the bow handle, then the bow limb can be retained in the bow, but slight shifting of the limb in the limb pocket can occur resulting in less accuracy
Solution Approach 1:
The patent replaces the purely mechanical limb pocket retention system with a chemical bonding system using adhesive composition. The adhesive is applied between the limb pocket and the bow limb to create a fixed, non-shifting connection, eliminating the lateral movement problems inherent in mechanical friction-based retention while maintaining secure attachment.
Solution Approach 2:
The adhesive composition acts as an intermediary substance between the limb pocket and the bow limb. This intermediary material fills the interface gap and creates a bonded connection that prevents relative movement between the two components, thereby eliminating shooting accuracy issues caused by limb shifting.
2Ease of repair
If the bow is disassembled and reassembled, then servicing can be performed, but changes in the fitment between the limb pocket and the limb can lead to different shooting performance
Solution Approach 1:
The adhesive composition is applied in advance during the initial assembly or servicing to establish a precise, fixed configuration between the limb pocket and the bow limb. This preliminary bonding action ensures that when the bow is disassembled and reassembled, the components return to their original precise configuration, maintaining consistent shooting performance across multiple service cycles.
3Stability of the object's composition
If the limb is fully secured in place, then stability is improved, but any degree of freedom in the fitment can lead to changes when the bow is serviced
Solution Approach 1:
The patent replaces the mechanical fitment system that allows some degree of freedom with a chemical bonding system. The adhesive composition creates a rigid, fixed connection between the limb pocket and the bow limb, eliminating lateral movement and positioning changes that would occur during disassembly and reassembly, while still allowing the bow to be serviced when needed.
