Bowstring Dampener with Protruding Rib for Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery bows experience vibrations after releasing the bowstring, which can be transmitted to the archer, making it difficult to handle and aim accurately and can cause unwanted noise that alerts target game.
Innovation Solution
A vibration dampener is mounted to the archery bow, comprising an elongate member with a dampening element made of vibration-dampening material, featuring a curved contact face and a laterally protruding rib to engage the bowstring, providing multiple contact points for energy absorption and minimizing rebound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional bows are used without dampeners, then the bowstring can be released freely, but vibrations are transmitted to the archer making it difficult to handle and aim accurately and causing unwanted noise
Solution Approach 1:
The dampener serves as an intermediary device mounted between the bowstring and the bow limb. It includes a dampening element with a contact face that contacts the bowstring and a laterally protruding rib that engages the bowstring during release. This intermediary structure absorbs vibrations and reduces noise transmission to the archer while allowing the bowstring to function normally.
Solution Approach 2:
The dampening element is made of vibration dampening material with specific physical properties. The contact face has a non-flat vertical profile with an initial contact point closer to the bowstring than subsequent contact points, changing the geometric parameters to optimize vibration absorption during the bowstring's forward oscillation after release.
2Ease of operation
If a dampener is mounted to reduce vibrations, then handling and aiming accuracy improve, but the device complexity increases
Solution Approach 1:
The dampener is divided into distinct functional segments: an elongate member that attaches to the bow body, and a separate dampening element mounted to the proximal end. The dampening element itself is segmented into a contact face for bowstring contact and a laterally protruding rib for engagement. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure manageable.
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 effectively reduces bowstring vibrations, enhancing handling and aiming accuracy by absorbing energy and minimizing noise, allowing for more precise and stealthy archery.
Implementation Method 1
a dampening element made of a vibration dampening material mounted to the proximal end between the proximal end and the bowstring
Implementation Method 2
The dampening element includes a laterally protruding rib extending outward from the contact face along at least a portion thereof to engage the bowstring when the bowstring is released

AI summary
An archery bow comprises an archery bow body defining opposing limb tips and a bowstring extending between the limb tips. The archery bow includes an elongate member extending from the bow body, the elongate member having a length and a proximal end arranged adjacent the bowstring. Additionally, the archery bow includes a dampening element made of a vibration dampening material mounted to the proximal end between the proximal end and the bowstring, the dampening element having a contact face adapted to contact the bowstring. In certain embodiments, the dampening element includes a laterally protruding rib extending outward from the contact face along at least a portion thereof to engage the bowstring when the bowstring is released.
