Curved Bowstring Vibration Dampener with Nested Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery bows experience vibrations after releasing the bowstring, which can hinder accurate handling and aiming due to transmitted vibrations and unwanted noise that may alert game.
Innovation Solution
A vibration dampener comprising an elongate member with a vibration-dampening material mounted between the bowstring and the bow body, where the elongate member is angled and curved, and a tubular rod with a radially curved section, both designed to mitigate bowstring vibrations by displacing vector forces and using a nested mounting area for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional straight rod dampeners are mounted perpendicular to the bowstring, then the mounting is simple, but the vibration reduction effectiveness is limited
Solution Approach 1:
The dampener rod is curved along its length rather than being straight, allowing it to engage the bowstring at an effective angle for vibration reduction while maintaining a compact configuration that simplifies mounting on the bow body
Solution Approach 2:
The dampener transitions from a one-dimensional straight rod to a three-dimensional curved structure, enabling it to simultaneously achieve effective vibration dampening angles and compact mounting footprint by utilizing spatial curvature
2Reliability
If the dampener is positioned close to the bowstring for effective vibration reduction, then vibration dampening improves, but the risk of interference with arrow clearance increases
Solution Approach 1:
The curved dampener rod is nested within the arrow clearance path, positioning it close to the bowstring for effective vibration reduction while its curved geometry ensures it does not protrude into the arrow's launch path, eliminating interference
Solution Approach 2:
The dampener is strategically positioned only in the critical vibration zone near the bowstring while maintaining clearance from the arrow path through its curved geometry, achieving localized vibration control without compromising arrow clearance
3Reliability
If the elongate member is angled non-perpendicular to the bowstring axis, then vector forces are effectively displaced for better vibration control, but the mounting alignment becomes more difficult
Solution Approach 1:
The curved geometry of the dampener rod inherently guides its installation at the optimal angled orientation, with the curve's shape providing mechanical guidance that naturally aligns the dampener at the correct angle to the bowstring, simplifying mounting alignment
Solution Approach 2:
The dampener features an asymmetric curved profile with a specific orientation that provides built-in alignment cues during installation, ensuring correct angular positioning relative to the bowstring without requiring complex alignment procedures

AI summary
An archery bow comprises an archery bow body defining opposing limb tips, a bowstring extending between the limb tips along a bowstring axis, and an elongate member extending from the bow body, the elongate member having a length and a proximal end arranged adjacent the bowstring. The archery bow further comprises a dampening element made of a vibration dampening material mounted to the proximal end of the elongate member between the proximal end and the bowstring. The elongate member extends from the bow body along a first axis non-perpendicular to the bowstring axis. Additionally, the elongate member may be curved along at least a portion of its length. In certain embodiments, the archery bow body defines a nested mounting area configured as an open channel to receive a distal end of the elongate member.
