Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing arrow rests for archery bows often fail to effectively stabilize the arrow shaft during drawing and release, leading to potential deviations from the desired flight path and lateral movement, which can affect accuracy and consistency.

Innovation Solution

A resilient, flexible sheet-based support piece is integrated into the arrow rest, extending radially across the frame to securely hold the arrow shaft in place, with pie-piece shaped flap pieces and radial extension slots aligning with the arrow's fletchings to minimize lateral movement and ensure proper alignment with the target path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fixed rigid arrow rest structure is used, then the arrow rest provides structural stability, but it fails to effectively stabilize the arrow shaft during drawing and release, allowing lateral movement

Engineering Contradiction:

Improvearrow shaft stabilizationVSAvoidarrow flight accuracy

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent applies the dynamics principle by replacing fixed rigid structures with resilient, flexible support pieces that can dynamically adapt to the arrow shaft's movement during drawing and release. The resilient material allows the support piece to move with the arrow while maintaining contact, providing continuous stabilization without restricting the drawing motion or allowing lateral escape.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the physical parameters of the support structure by using resilient, flexible sheet-based material instead of rigid fixed structures. This material property change enables the support piece to deform and conform to the arrow shaft's position changes during the draw cycle, maintaining effective stabilization throughout the motion range.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a resilient, flexible sheet-based support piece is used, then the arrow shaft is securely held in place with minimal lateral movement, but the structure becomes more complex

Engineering Contradiction:

Improvearrow shaft stabilizationVSAvoidarrow rest structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the flexible shells and thin films principle by using a resilient, flexible sheet-based support piece that can be formed into various configurations (including pie-piece shaped flaps and radial extensions). This flexible material provides effective arrow shaft stabilization while maintaining a relatively simple overall structure that can be manufactured as a single integrated component.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If the support piece extends radially across the frame, then the arrow shaft is prevented from laterally escaping, but the alignment with fletchings becomes more difficult to achieve

Engineering Contradiction:

Improvelateral containmentVSAvoidfletching alignment

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies the segmentation principle by dividing the radial support structure into multiple pie-piece shaped flap pieces that can independently align with specific fletching positions. This segmentation allows each flap to be positioned and shaped to match the arrow's fletching orientation, ensuring precise alignment while maintaining overall lateral containment through the complete radial extension.

Inventive Principle:

Principle #1Segmentation

AI summary

Certain embodiments of the present invention provide an arrow rest usable with an archery bow to support an arrow shaft in a ready-to-draw position during the draw and until the release of the arrow by an archer. The arrow rest preferably aligns an elongate axis of the arrow shaft in a desired path which the arrow follows during release from the bow and at least initially towards the target. In certain embodiments, the arrow rest includes a support frame mounted to an archery bow riser. At least one resilient, inwardly extending support piece made from a sheet-based material extends across the frame to radially support portions of the arrow shaft. In use, arrow rests according to preferred embodiments of the present invention preferably support the arrow in place and impede the arrow from laterally escaping from the arrow rest.
