Solution Overview

Problem

Current bowstring weights, such as brass speed nocks and machined brass stacks, are difficult to install, costly, and do not effectively reduce string vibration and noise, posing safety risks and requiring additional noise-reducing measures.

Innovation Solution

A bowstring weight design featuring a metal sleeve encapsulated within a polymeric body that oscillates to dampen vibration and reduce noise, allowing for easier installation and centralized weight distribution without direct contact with the bowstring.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If multiple individual brass nocks or machined brass stacks are used to increase bowstring weight, then the arrow speed increases, but the installation difficulty and cost increase significantly

Engineering Contradiction:

Improvearrow speedVSAvoidinstallation ease

Core Design Contradiction:

SpeedVSEase of operation

Solution Approach 1:

The patent combines multiple individual brass nocks into a single integrated machined brass stack component. This merging eliminates the need to install multiple separate nocks individually, reducing installation complexity and time while maintaining the total weight required for arrow speed enhancement.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The machined brass stack serves multiple functions simultaneously: it provides the necessary weight for arrow speed, acts as a single installable unit simplifying the installation process, and eliminates the need for separate vibration dampening components by integrating damping features into the stack structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Speed

If multiple individual brass nocks are installed to achieve required weight, then the arrow speed increases, but the installation time and complexity increase

Engineering Contradiction:

Improvearrow speedVSAvoidinstallation time

Core Design Contradiction:

SpeedVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

3Speed

If brass speed nocks are installed to increase arrow speed, then the bow performance improves, but string vibration and noise are not reduced

Engineering Contradiction:

Improvearrow speedVSAvoidstring vibration and noise

Core Design Contradiction:

SpeedVSObject-generated harmful factors

Solution Approach 1:

The patent merges the weight function and vibration dampening function into a single integrated component. The machined brass stack includes embedded vibration dampening elements that work simultaneously with the weight function, eliminating the need for separate dampeners and reducing both string vibration and noise while maintaining arrow speed enhancement.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The machined brass stack incorporates composite construction, combining brass material for weight with integrated vibration dampening features. This composite approach allows the single component to provide both mass for speed enhancement and vibration reduction capabilities.

Inventive Principle:

Principle #40Composite materials

Core Design Contradiction:

SpeedVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

5Reliability

If brass nocks are crimped onto the bowstring to hold them in place, then the nocks remain secured, but the crimping process may alter or move previously placed nocks

AI summary

An archery bowstring weight is provided including a sleeve that is encapsulated and suspended at least partially within an overmolded polymeric body forming an exterior of the bowstring weight. The sleeve can be a metal body, such as a ring, that floats or moves inside the polymeric body when the bowstring vibrates to dampen vibration of the bowstring. The sleeve can be isolated or separated from the bowstring by an inner wall of the polymeric body that is disposed between the bowstring and the sleeve when the weight is installed on the bowstring. The oscillation of the sleeve inside the overmolded polymeric body also can attenuate string oscillation and reduce string noise. A related method is provided.
