Archery Bow Vibration Absorber with Adjustable Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration and noise dampening devices for archery bows are inflexible and cannot be adjusted to meet varying user needs or environments.
Innovation Solution
A vibration absorber comprising a hollow cylindrical cap with two elastic dampening plugs, which can be coupled together and adjusted by varying the number of weights and the length of a stabilizer, allowing for customizable elasticity between 25 to 60 Durometers to optimize shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed characteristic vibration absorbers are used, then vibration and noise are absorbed, but the device cannot be adjusted to meet varying user needs or environmental conditions
Solution Approach 1:
The vibration absorber employs adjustable weights that can be moved along the stabilizer bar to different positions, allowing the device to dynamically adapt its vibration absorption characteristics. This dynamic adjustment mechanism enables users to customize the vibration dampening properties without requiring a completely different device design, thus improving adaptability while controlling complexity.
Solution Approach 2:
The device allows users to change the distribution of weights along the stabilizer, effectively altering the mass distribution parameter of the vibration absorber. By adjusting the position and configuration of the weights, users can modify the natural frequency and damping characteristics of the system to match different shooting conditions and personal preferences, resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If multiple adjustable components are added to enable customization, then adaptability improves, but device complexity increases
Solution Approach 1:
The vibration absorber is divided into modular components including the stabilizer bar, multiple adjustable weights, and connection mechanisms. This segmentation allows users to independently adjust each weight's position along the stabilizer, providing fine-grained customization capability. The modular design enables adaptability through component arrangement rather than through complex integrated mechanisms, thus improving customization while managing overall device complexity.

AI summary
A vibration absorber for an archery bow including a hollow, elongated cap open at both ends, a first dampening plug inserted into one of the ends of the cap and a second dampening plug inserted to another end of the cap and coupled to the first dampening plug within the cap. Typically the cap is made from a stiff material and the first and second dampening plugs are made from elastic material with the same or different elasticities.
