Solution Overview

Problem

Conventional arrow rests often require complex and time-consuming mechanical adjustments to accommodate different arrow shaft diameters and fail to maintain the arrow shaft in a reliable position during launch, while also interfering with the fletching or vanes.

Innovation Solution

An arrow rest with a frame and vertical post that allows the arrow shaft to pass through, featuring adjustable spring arms and rigid members to maintain the arrow's position, minimizing friction and accommodating various diameters, and optionally using brushes or rollers for securement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional arrow rests use fixed supporting members to hold the arrow shaft, then the arrow shaft is maintained in position, but the fletching or vanes interfere with the supporting members during discharge

Engineering Contradiction:

Improvearrow shaft position stabilityVSAvoidfletching interference

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The arrow rest is divided into separate functional components: a frame structure that defines the opening and a distinct vertical post that contacts the arrow shaft. This segmentation allows the fletching to pass through the opening without interfering with the supporting members, as the contact point is elevated and separated from the discharge path.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The supporting surface is moved from a horizontal plane to a vertical dimension by extending the post upwardly from the frame. This vertical positioning allows the arrow shaft to be held at an elevated position where it does not conflict with the horizontally discharging fletching, resolving the interference problem while maintaining positional stability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If conventional arrow rests are designed for a specific arrow shaft diameter, then the arrow shaft is securely held, but mechanical adjustments are required when changing to different diameter arrow shafts

Engineering Contradiction:

Improvearrow shaft securingVSAvoidmechanical adjustment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The vertical post is designed with a conical or tapered surface that can accommodate arrow shafts of various diameters. The spring-loaded mechanism allows the post to flex and adapt to different shaft sizes, providing universal compatibility without requiring mechanical adjustments when changing arrow shafts.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The spring pressure and vertical post position are made variable to adapt to different arrow shaft diameters. The spring mechanism automatically adjusts the contact pressure and positioning based on the shaft diameter, eliminating the need for manual mechanical adjustments while maintaining reliable securing for various shaft sizes.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If conventional arrow rests use rigid supporting members, then the arrow shaft is firmly held, but friction and interference occur during arrow discharge

Engineering Contradiction:

Improvearrow shaft holdingVSAvoidfriction during discharge

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The vertical post is made flexible through spring loading, allowing it to dynamically adjust during the arrow discharge process. The spring mechanism permits the post to flex backward as the arrow is drawn and released, reducing friction and interference with the moving arrow shaft while maintaining firm holding during the loaded position.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The spring-loaded vertical post acts as a flexible supporting element that can deform elastically during arrow discharge. This flexibility reduces the frictional contact between the supporting member and the arrow shaft during motion, while still providing adequate holding force when the arrow is stationary in the loaded position.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

An arrow rest for an archery bow includes a frame and a vertical post extending upwardly from the frame so that the frame at least partially encircles the vertical post to form an arrow shaft pass-through. The arrow rest further includes a pair of spring arms, brushes and/or rollers extending generally toward the arrow shaft pass-through.
