Gated Archery Rest With Segmented Spring Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrow rests either fail to securely retain the arrow during drawing and shooting, leading to frictional losses and fletching contact issues, or suffer from excessive wear and loading difficulties due to brush materials.
Innovation Solution
A segmented ring-shaped arrow rest with three spring-loaded supports at 0, 120, and 240 degrees, featuring a pivotally attached gate that minimizes fletching contact and reduces friction, and a spring-loaded launcher system for secure arrow retention and easy loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brush bristles are used to support the arrow, then arrow containment is improved, but frictional losses and fletching contact increase
Solution Approach 1:
The arrow support is divided into multiple discrete prongs (typically three) arranged in a triangular pattern, rather than using continuous brush bristles. Each prong is a separate element that contacts the arrow at specific points, providing containment while minimizing surface area contact and thus reducing frictional losses and fletching wear.
Solution Approach 2:
The harmful brush material is completely removed from the design. Instead of using bristles that inherently create friction and wear, the invention extracts this element and replaces it with smooth, rigid prongs made of low-friction material that provide the necessary mechanical support without the detrimental frictional effects.
2Reliability
If spring-loaded supports are used, then arrow retention is improved, but device complexity increases
Solution Approach 1:
The arrow support prongs are designed to be movable rather than fixed, allowing them to flex and adapt to the arrow's position. The springs provide a dynamic retention mechanism that automatically adjusts to the arrow's insertion and shooting cycle, improving reliability without requiring complex mechanical structures.
Solution Approach 2:
The spring mechanism is integrated directly into the prong structure itself, combining the support function and the retention function into a single unified element. This merging eliminates the need for separate complex mechanisms while achieving both structural support and reliable arrow retention through the spring-loaded design.
3Reliability
If a gate is added to prevent arrow displacement, then arrow retention is improved, but ease of operation deteriorates
Solution Approach 1:
The gate is pre-positioned in an open state during the loading phase, allowing easy arrow insertion. After the arrow is loaded and positioned, the gate automatically closes or is closed to secure the arrow. This preliminary positioning of the gate in the appropriate state for each phase of operation resolves the contradiction between easy loading and secure retention.
Solution Approach 2:
The gate mechanism is designed to operate automatically or semi-automatically, utilizing the arrow's own insertion motion or the spring-loaded prongs' movement to trigger the gate's closing action. This self-service mechanism eliminates the need for separate manual operations to secure the arrow, maintaining ease of operation while improving retention.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides reduced frictional losses, improved accuracy by minimizing fletching contact, reduced wear, and easier loading with enhanced arrow retention, preventing arrow displacement during drawing and shooting.
Implementation Method 1
At least two pivoting arrow supports are pivotally attached to the ring and biased toward the shooting position of the center opening. The pivoting arrow supports are biased to capture the arrow against the fixed arrow support in the shooting position of the center opening.

AI summary
An arrow rest for retaining an arrow in a shooting position on an archery bow. The arrow rest includes a generally ring shaped structure surrounding a center opening. The ring structure includes a gap configured to receive the arrow in the center opening. A gate is pivotally attached to the ring structure and biased to extend across the gap in a closed position. At least one fixed arrow support is attached to the ring and extends into the center opening toward the shooting position. At least two pivoting arrow supports are pivotally attached to the ring and biased toward the shooting position of the center opening. The pivoting arrow supports are biased to capture the arrow against the fixed arrow support in the shooting position of the center opening and to rotate away from the shooting position when the arrow is launched from the archery bow.
