Solution Overview

Problem

Traditional archery lacks the ability to make aiming point adjustments while at full draw, as both hands are required to hold the bow, preventing supported shooting and accurate alignment.

Innovation Solution

A coupler that connects an archery bow to an adjustable firearm shooting support, allowing vertical and horizontal adjustments via a trigger mechanism, enabling sight alignment without removing hands from the bow or string, using a housing with an actuator lever and linkage to interact with the firearm support's trigger mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If both hands are used to hold the bow at full draw, then the bow remains stable and sight alignment is achieved, but the archer cannot make adjustments to the shooting support

Engineering Contradiction:
Improvesight alignment accuracyVSAvoidability to adjust support
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The coupler acts as an intermediary device between the bow and the shooting support. It includes a trigger mechanism that the archer can activate with one hand while maintaining full draw with both hands. The coupler translates the trigger activation into vertical movement of the shooting support, allowing sight alignment adjustments without releasing the bow string or handle.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the archer removes one hand from the bow to adjust the support, then the support can be repositioned, but full draw is lost and the shot becomes impossible

Engineering Contradiction:
Improveability to adjust supportVSAvoidmaintaining full draw
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The coupler is designed to be self-activating through the archer's existing full draw position. The trigger mechanism is positioned so that the archer's hand naturally contacts it during full draw, or can be activated with minimal movement that doesn't compromise the draw position. The system serves itself by using the archer's necessary holding position as the activation mechanism.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If a fixed shooting support is used, then the bow can be supported for accuracy, but the aiming point cannot be adjusted while at full draw

Engineering Contradiction:
Improveshooting accuracyVSAvoidadjustability of aiming point
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The shooting support is transformed from a fixed, static device to a dynamic, adjustable one. The coupler incorporates a trigger mechanism that allows the archer to dynamically adjust the vertical position of the support while maintaining full draw. This enables the aiming point to be adapted and fine-tuned without changing the fundamental supported shooting position.

Inventive Principle:
Principle #15Dynamics

AI summary

A coupler for interconnecting an archery bow and an adjustable firearm shooting support includes a housing with an actuator lever and a lower actuator extending respectively therefrom and being pivotally interconnected to opposite ends of a linkage. The firearm support is vertically adjustable and activated by a trigger mechanism whereby activation of the actuator lever causes the lower actuator to pivot outwardly into contact with the firearm support trigger to allow vertical adjustability of the bow and whereby deactivation of the actuator lever stabilizes movement of the bow into a support or rest position.
