Mouthpiece Bow String Release System for Accuracy

Solution Overview

Problem

Conventional bow string releases fail to completely prevent shaking and vibration when used, leading to reduced arrow accuracy and a high risk of accidental shooting due to their sensitivity.

Innovation Solution

A mouthpiece-type bow string release system that uses upper and lower mouthpieces with push and pressure receiving units to transmit a signal for controlled bow string release, minimizing accidental shooting by requiring successive engagement of switching elements for arrow release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional bow string release is used to minimize impact when releasing the bow string, then the shaking or vibration is reduced, but the structure becomes excessively sensitive causing accidental release

Engineering Contradiction:

Improveshaking or vibrationVSAvoidaccidental release

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The release trigger mechanism is divided into multiple independent components: a first trigger for initial engagement and a second trigger for final release. This segmentation allows the system to reduce sensitivity to accidental shocks while maintaining controlled release capability through sequential activation of distinct trigger elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system requires preliminary engagement of the first trigger before the second trigger can be activated. This preliminary action creates a staged release process where the bow string is initially secured by the first trigger, then requires a separate deliberate action on the second trigger to release, preventing accidental discharge from minor shocks.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If a user directly holds the bow string with hand to release it, then the structure is simple, but the accuracy rate is lowered due to unstable breathing or shaking

Engineering Contradiction:

ImprovestructureVSAvoidaccuracy rate

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The bow string release device serves as an intermediary mechanism between the user and the bow string. Instead of direct hand contact with the bow string, the user operates triggers that control release mechanisms (rollers and notches) which in turn release the bow string. This intermediary system eliminates the direct connection between user body movement and bow string release, thereby improving accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)
