Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing archery bow accessories, such as arrow rests and sights, are difficult to adjust, prone to misalignment, and lack convenient installation and removal, leading to performance instability and reduced shooting accuracy.

Innovation Solution

A bow accessory coupler with flexible clamp arms that securely attach to the bow riser using a dovetail-shaped rail, allowing vertical and lateral adjustment without direct contact with the riser, and a fastener for securing the position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a rigid mount with locking screw is used to attach sight to bow riser, then the sight can be vertically adjusted along groove, but the locking screw creates gap and point force causing instability and vibrations

Engineering Contradiction:

Improvevertical adjustment capabilityVSAvoidsight stability on riser

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent removes the locking screw and its associated groove from the mounting system. Instead, the flexible mount uses elastic deformation of its arms to engage with the riser, eliminating the source of gaps and point forces that caused instability and vibrations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs flexible arms made of elastomeric material that bend and deform elastically to engage with the bow riser. This flexibility allows the mount to conform to the riser surface while maintaining stable contact without creating gaps or concentrated point forces.

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If arrow rest is screwed onto bow riser using preexisting hole, then the arrow rest is securely attached, but it is difficult or cumbersome to adjust position after installation

Engineering Contradiction:

Improveattachment securityVSAvoidposition adjustability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent creates a dynamic mounting system where the flexible arms can be deformed to release or tighten the grip on the riser. By applying force to the arms, the user can easily adjust the position or remove the accessory, then release the force to secure it again, combining security with ease of adjustment.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the physical state of the mounting arms from rigid to flexible, allowing them to deform elastically. This parameter change enables the mount to transition between a secure locked state and an adjustable state by simply applying mechanical force to deform the arms.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If adhesive is used to attach arrow rest to bow, then installation is simple, but adhesion fails after prolonged use and wear and tear

Engineering Contradiction:

Improveinstallation simplicityVSAvoidattachment durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces the chemical bonding mechanism of adhesives with a mechanical attachment system using flexible arms that grip the riser physically. This mechanical system provides both simple installation (no adhesive application needed) and high reliability (positive mechanical grip that doesn't degrade over time).

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If arrow rest is kept installed during transportation, then it remains ready for use, but transportation forces cause orientation to become unintentionally changed or misaligned

Engineering Contradiction:

Improvereadiness for useVSAvoidorientation alignment

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The flexible arms can deform under transportation forces to absorb shocks and prevent misalignment, while maintaining secure attachment. This flexibility allows the mount to accommodate external forces without transferring them to the accessory orientation.

Inventive Principle:

Principle #30Flexible shells and thin films
