C-Shaped Arrow Rest Frame with Flexible Retainer Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrow rests for archery equipment often fail to securely hold the arrow in place when the bow is tilted, leading to potential misfires if the arrow slips from the launching position, especially during hunting or bow fishing.
Innovation Solution
A C-shaped arrow rest frame with a flexible retainer pin and adjustable attachment mechanism that securely positions the arrow on the bow frame, ensuring it remains in place vertically or when tilted, using a combination of a frame attachment segment, guard segment, arrow support segment, and pin support segment to prevent arrow displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple arrow rest design is used, then the device complexity is reduced, but the arrow may slip from the launching position when the bow is tilted
Solution Approach 1:
The arrow rest is divided into multiple functional segments: a frame attachment segment for mounting to the bow, a guard segment for protecting the arrow, an arrow support segment for holding the arrow, and a pin support segment for securing the arrow in place. This segmentation allows each part to perform its specific function effectively while maintaining overall structural integrity and reliability.
Solution Approach 2:
A flexible retainer pin acts as an intermediary element between the pin support segment and the arrow. The pin extends into the frame opening and provides a reliable connection point that prevents the arrow from slipping, while the flexibility of the pin allows it to accommodate minor position adjustments and bow movements.
2Reliability
If the arrow rest is designed to securely hold the arrow when tilted, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The C-shaped arrow rest frame serves multiple functions simultaneously: it provides structural support for the arrow, acts as a mounting structure for attachment to the bow, incorporates a guard segment for protection, and includes a pin support segment for securing the arrow. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving reliable arrow retention.
3Reliability
If a flexible retainer pin is used, then the arrow position stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The retainer pin is designed with specific material properties and geometric parameters that optimize its performance. The flexibility of the pin is carefully controlled through material selection and cross-sectional dimensions, allowing it to reliably hold the arrow while remaining manufacturable using standard fabrication processes.
