Irregular Rib Elastomeric Stabilizer for Broadband Vibration Dampening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery bow stabilizers are inefficient in dampening a wide range of vibrations and are not universally compatible with different types of bows, leading to reduced accuracy and discomfort for the shooter due to residual energy and vibration transmission.
Innovation Solution
The novel bow accessory features an elastomeric component with a rib configuration that has a margin-defining edge with an irregular profile, providing a stiff inner segment for high-frequency vibration dampening and a flexible outer segment for low-frequency dampening, allowing for multiple operating modes and effective vibration reduction across a broader frequency spectrum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional stabilizers with uniformly circular ribs are used, then the device complexity is reduced and manufacturing is easier, but the vibration dampening effectiveness across different frequency ranges is insufficient
Solution Approach 1:
The rib configuration is divided into different segments with varying properties: inner ribs with larger cross-sections for high-frequency dampening and outer ribs with smaller cross-sections for low-frequency dampening. This local differentiation optimizes vibration dampening across the entire frequency spectrum while maintaining a relatively simple overall structure.
Solution Approach 2:
The stabilizer's rib structure is segmented into multiple distinct ribs rather than using a uniform continuous structure. Each rib can be independently optimized for specific frequency ranges, allowing the system to address multiple vibration modes simultaneously without requiring a completely complex design.
2Reliability
If stabilizers are designed for specific bow types, then the vibration dampening performance is optimized for that specific application, but the adaptability to different bow types is reduced
Solution Approach 1:
The stabilizer is designed with a universal mounting interface and a rib configuration that can effectively dampen vibrations across various bow types including compound bows, recurve bows, and longbows. The multi-segment rib structure provides broad-spectrum vibration dampening that adapts to different bow characteristics without requiring custom design for each bow type.
3Stability of the object's composition
If long rodlike stabilizers are used to extend well in front of the bow, then the balance improvement is achieved, but the device length increases and may interfere with the shooter's stance or environment
Solution Approach 1:
The stabilizer uses a ribbed elastomeric structure that provides effective balance and vibration dampening with a more compact form factor compared to traditional long rodlike stabilizers. The rib configuration allows the stabilizer to achieve its stabilizing function with reduced length, minimizing interference with the shooter's stance and surrounding environment while maintaining bow balance.
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 significantly enhances vibration dampening efficiency, resulting in a quieter and smoother shooting experience, reduced bow movement, and improved balance, making it more effective than prior art stabilizers and compatible with a variety of bows.
Implementation Method 1
A superior, commercially available bow stabilizer of this type is illustrated in FIG. 1 and identified by reference character 20. Ribs 24a . . . g are located between an integral, stemmed, mushroom-shaped end member 30 and an integral, frustoconical end member 32. The vibrational are complex Ribs 24a . . . 24g effectively reduce these motions because they have multiple degrees of freedom which allow them to move universally; i.e., in any direction in a 360° (spherical) pattern.
Implementation Method 2
The novel, improved bow B/D accessories disclosed herein resemble prior art stabilizer 20 in that they have an elastomeric component which includes a set of axially aligned, annual ribs separated by integral stems and embraced by integral end pieces. However, the B/D accessories of the present invention are, significantly more effective in reducing vibration than the FIG. 1 type stabilizer 20
Implementation Method 3
The rib configuration which has a margin-defining edge with an irregular profile or, stated otherwise, a margin-defining edge which has a variable height relative to the axial centerline of the elastomeric component. The rib configurations of the present invention as described in the preceding paragraph produce ribs having a relatively stiff inner segment which efficiently dampens vibrations (including shock and sound) that have a high frequency and a more flexible outer segment which efficiently dampens vibrations which lower frequencies.

AI summary
B/D archery bow accessories which have an elastomeric vibration dampening component mounted on an elongated, rigid support. The elastomeric component has a set of integral vibration dampening elements such as ribs. The vibration dampening elements have irregular profile configurations which make these elements capable of dampening with high efficiency the sets of vibrational frequencies generated: (a) when an arrow is shot, and (b) during and after the ensuing lock-up. Vibration dampening efficiency may be promoted by making the elastomeric component from a material of the most optimal hardness that is practical and by employing end pieces at opposite ends of the elastomeric component.
