Solution Overview

Problem

Cocking mechanisms for bow weapons often require users to re-grasp and reposition their hands, involving entire-body effort and specialist equipment, which is cumbersome and inefficient.

Innovation Solution

A foldable cocking mechanism with a trigger section and release section that can be folded with respect to an axis, allowing the user to change states without re-grasping, featuring a trigger element and rocker configuration that engages and separates to facilitate cocking without additional handles or grips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional cocking mechanism is used, then the weapon can be cocked, but the user must re-grasp and reposition their hands, involving entire-body effort and specialist equipment

Engineering Contradiction:
Improveease of cocking operationVSAvoidcomplexity of cocking mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cocking mechanism is divided into two distinct foldable sections: a trigger section containing the trigger element and a release section containing the rocker. These sections can be folded relative to each other about an axis, allowing the cocking action to be performed without re-grasping the weapon. The segmentation enables each section to be optimized for its specific function while working together as an integrated system.

Inventive Principle:
Principle #1Segmentation

2Loss of time

If the trigger section and release section are made foldable, then the user can change state without re-grasping, but the mechanism structure becomes more complex

Engineering Contradiction:
Improvetime for cocking actionVSAvoidstructural complexity of foldable mechanism
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The mechanism transitions from a static configuration to a dynamic one, where the trigger section and release section can fold relative to each other about an axis. This dynamic capability allows the mechanism to adapt between different operational states (cocked and uncocked) without requiring the user to release and re-grasp the weapon, thereby reducing the time lost during the cocking action.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the trigger element engages with the rocker in the firing state, then the weapon can be fired, but the mechanism must be carefully assembled and aligned

Engineering Contradiction:
Improvereliability of trigger mechanismVSAvoidease of assembling mechanism
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By segmenting the mechanism into distinct trigger and release sections that fold relative to each other, the assembly process can be simplified. Each section can be manufactured and tested independently, then assembled by establishing the foldable connection about the axis. This segmentation allows for easier alignment and assembly while maintaining the reliability of the trigger-rockor engagement in the firing state.

Inventive Principle:
Principle #1Segmentation
