Crossbow Magazine Locking Lever and Magnetic Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crossbow designs require multiple steps and complex mechanisms for attaching and detaching magazines, which can lead to accidental ejection or misfiring, especially in stressful situations, and are difficult for individuals with limited fine motor skills.
Innovation Solution
A crossbow design featuring a locking lever with a pivotable actuating plate and magnetic engagement for quick and reliable magazine attachment and detachment, along with a safety device to prevent accidental firing, allowing single-handed operation even with gloves or cold hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism with multiple steps is used to secure the magazine, then the magazine attachment is more secure, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent replaces complex multi-step mechanical locking mechanisms with a simple lever-based release system. The lever (302) connects to the magazine retention member (301) and can be actuated by the shooter to quickly release the magazine without requiring multiple manual steps or fine motor skills, thus maintaining security while simplifying operation.
2Device complexity
If a small lever is used for magazine release, then the mechanism is compact, but it is difficult to operate with cold hands or while wearing gloves
Solution Approach 1:
The patent extends the lever (302) beyond the confines of the receiver (303) to protrude outward. This dimensional extension allows the shooter to access and actuate the lever with their fingers even when wearing gloves or having cold hands, while the lever remains connected to the compact retention mechanism inside the receiver.
3Productivity
If the magazine is easily removable, then magazine exchange is quick, but accidental ejection may occur
Solution Approach 1:
The patent designs the lever (302) and retention member (301) system so that the magazine remains securely held during normal operation without requiring active engagement. The retention member automatically maintains holding force, and only deliberate actuation of the lever releases the magazine, preventing accidental ejection while allowing quick intentional removal.
