Solution Overview

Problem

Conventional bows require extra steps and operations that interrupt shooting accuracy and pose safety risks, such as finger injury from the trigger mechanism.

Innovation Solution

A rapid repeating device with a control component that allows continuous shooting without removing the finger from the trigger, featuring a control handle unit that pivots to control the control component's movement, ensuring the trigger unit remains stationary, and includes safety mechanisms to prevent accidental arrow release.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional bow designs require pulling the trigger finger away from the trigger for each loading operation, then the loading mechanism can be operated, but the user's shooting accuracy is interrupted and finger injury risk increases

Engineering Contradiction:
Improveloading operationVSAvoidshooting accuracy and finger safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent extracts the loading operation from the trigger mechanism by introducing a separate control component with a control handle unit. This allows the loading function to be operated independently through a dedicated control component that moves along a guide rail, separating the loading action from the trigger pull action. The trigger unit remains stationary and dedicated solely to shooting activation, eliminating the need to remove fingers from the trigger during loading operations.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the bow's control functions into distinct components: the trigger unit for shooting activation and the control component with control handle unit for loading operations. This segmentation allows each component to perform its specific function independently - the trigger unit remains stationary for accurate shooting while the control component handles loading through its own dedicated control mechanism, preventing interference between functions.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If the trigger moves during operation in conventional bows, then the loading mechanism can function, but the user's finger may be caught between the trigger and trigger guard causing injury

Engineering Contradiction:
Improveloading mechanism functionVSAvoidfinger injury risk
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the loading control function from the trigger assembly by providing a separate control component with control handle unit. The trigger unit is designed to remain stationary during loading operations, with only the control component moving along the guide rail. This extraction eliminates the harmful movement of the trigger during loading, preventing finger pinching while maintaining full loading functionality through the dedicated control mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If extra steps are required for continuous shooting in conventional bows, then the bow can be reloaded, but the operation time increases and shooting flow is interrupted

Engineering Contradiction:
Improvecontinuous shooting capabilityVSAvoidoperation time between shots
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent enables continuous shooting by providing a dedicated control component with control handle unit that can operate independently and continuously for loading. The control component moves along a guide rail to access arrows in the arrow box and load them onto the bowstring without interrupting the shooting flow. The trigger unit remains stationary and ready for immediate activation, allowing the shooter to maintain continuous action without pausing to manipulate the trigger for loading purposes.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A rapid repeating device is provided. The rapid repeating device includes a main body including an arrow portion, a shooting portion with a bowstring component, and a trigger portion with a trigger unit. A control component is disposed in the arrow portion and partially located inside the main body and partially exposed outside the arrow portion. When the control component moves toward the shooting portion, the control component is away from the trigger unit, and when the control component moves away from the shooting portion, the control component movably abuts against the trigger unit. An arrow box is disposed on the top of the main body, and a plurality of arrows are disposed in the arrow box and one by one fall into the control component that is partially exposed outside the arrow portion.
