Gated Archery Rest With Pivotally Biased Arrow Supports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery rests either fail to securely hold the arrow, leading to potential falls during drawing or shooting, or they cause significant friction and wear on the arrow's fletching, affecting accuracy and requiring frequent replacement of materials.
Innovation Solution
A gated arrow rest with pivotally attached, radially extending supports that capture and secure the arrow, minimizing friction and wear while allowing easy loading and preventing arrow displacement, featuring an adjustable stop for customizable holding force and low-friction surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring-biased U-shaped trough rest is used, then the rest provides sufficient support and rigidity, but the arrow can easily fall off during drawing or shooting
Solution Approach 1:
The patent employs movable arrow supports that can shift position dynamically. The supports are mounted to move along the ring structure, allowing them to adapt to the arrow's position during loading and shooting. This dynamic capability enables the rest to securely hold the arrow while still permitting easy loading, as the supports can move out of the way during insertion and then engage to prevent the arrow from falling off.
2Reliability
If brush bristles are used to support the arrow, then good containment is provided, but significant frictional losses and fletching wear occur
Solution Approach 1:
The patent changes the material parameter of the arrow supports from soft brush bristles to hard, low-friction materials such as metal or hard plastic. This parameter change maintains the containment function while dramatically reducing frictional losses and fletching wear. The hard supports provide sufficient containment through their geometric arrangement and movement characteristics rather than through frictional engagement.
3Reliability
If brush material is used for arrow support, then containment is achieved, but the material is consumed during shooting requiring frequent replacement
Solution Approach 1:
The patent changes the material parameter from consumable brush material to durable, non-consumable hard materials. The metal or hard plastic supports do not wear down or deform during repeated use, eliminating the need for frequent replacement while maintaining effective arrow containment throughout the rest's service life.
4Loss of energy
If spaced apart support shoes with bristles are used, then frictional losses are reduced, but arrows can fall between the lower brushes or be expelled upward
Solution Approach 1:
The patent employs movable supports that can dynamically adjust their position. During normal shooting, the supports are spaced to minimize friction. However, when an arrow attempts to fall between the lower supports or be expelled upward, the movable supports can shift to close the gaps and engage the arrow, preventing it from leaving the rest. This dynamic response maintains both low friction and high reliability.
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 secure arrow retention with reduced frictional losses and fletching contact, enhancing accuracy and reducing wear on the arrow rest materials, making it easier to load and draw the bow without arrow loss.
Implementation Method 1
A gate is pivotally attached to the structure and biased to extend across the gap so the structure completely surrounds the opening when the gate is in the closed position
Implementation Method 2
At least one of the arrow supports is movably attached to the structure and is biased toward the shooting position. The movable arrow supports are biased to capture the arrow against the other arrow supports in the shooting position

AI summary
An arrow rest for retaining an arrow in a shooting position on an archery bow. The arrow rest includes a structure surrounding a opening. The structure including a gap configured to pass the arrow into the opening. A gate is pivotally attached to the structure and biased to extend across the gap in a closed position. The structure completely surrounds the opening when the gate is in the closed position. A plurality of arrow supports are attached to the structure and extend radially into the opening toward the shooting position. At least one of the arrow supports is pivotally attached to the structure and biased toward the shooting position. The arrow support is biased to capture the arrow against the other arrow supports in the shooting position and to be displaced away from the shooting position when the arrow is launched from the archery bow.
