Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Fall away arrow rests in bowhunting generate noise due to friction between the arrow and the rest, which can scare game and hinder hunting efforts.

Innovation Solution

A launcher rest apparatus comprising a sheet of materials adhered to a bow rest launcher, featuring a specific shape and configuration to reduce noise by minimizing friction between the arrow and the launcher during draw.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional arrow rest launcher is used, then the arrow is supported during bow firing, but noise is generated due to friction between the arrow and launcher

Engineering Contradiction:

ImprovenoiseVSAvoidarrow support function

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

A sheet material is introduced as an intermediary between the arrow and the launcher. This sheet is adhered to the launcher surface, allowing the arrow to slide over it with reduced friction and noise, while still maintaining proper arrow support and positioning during the firing process.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The friction parameter between the arrow and launcher is changed by applying a different material surface. The sheet material has different friction characteristics than the original launcher surface, reducing the friction force and consequently the noise generated during arrow sliding.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the arrow rest launcher surface is modified to reduce friction, then noise is reduced, but the durability of the launcher surface may be compromised

Engineering Contradiction:

ImprovenoiseVSAvoidlauncher surface durability

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

A composite structure is created by adhering a sheet material to the launcher surface. This combines the durability of the original launcher with the low-friction properties of the sheet material, achieving both noise reduction and surface durability.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The sheet material serves as a replaceable, sacrificial layer that protects the permanent launcher surface. When the sheet wears out, it can be replaced without damaging the underlying launcher structure.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
