Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for rifles are complex and require a power supply, making them unreliable for preventing unintended firing.
Innovation Solution
A mechanical safety device with an insert for the magazine well that includes a locking element engaging in a locking groove, a firing pin safety, and a trigger safety, operated independently of a power supply, preventing unauthorized use and firing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic security mechanisms with biometric sensors and electric drives are used, then the safety device can provide advanced authentication and control, but the device complexity increases and a power supply is required
Solution Approach 1:
The patent extracts the essential safety function from complex electronic systems and implements it through a simple mechanical locking element that can be removed or inserted into a locking groove, eliminating the need for power supplies and electronic components while maintaining reliable safety control
Solution Approach 2:
The patent employs a simple, inexpensive mechanical locking element that can be easily manufactured and replaced, providing reliable safety functionality without the cost and complexity of electronic systems
2Reliability
If electronic security mechanisms with biometric sensors and electric drives are used, then the safety device can provide advanced authentication and control, but the ease of operation decreases due to additional power supply requirements
Solution Approach 1:
The patent removes power supply requirements and electronic components from the safety mechanism, retaining only the essential mechanical locking and release functions, thereby simplifying operation while maintaining safety reliability
Solution Approach 2:
The mechanical locking element is designed to be manually operated without external power sources, allowing the user to directly control the safety function through simple manual insertion and removal actions
3Device complexity
If a mechanical lock with locking elements and locking grooves is used, then the device complexity decreases and no power supply is needed, but the reliability of preventing unintended firing must be ensured through proper mechanical design
Solution Approach 1:
The patent divides the safety mechanism into distinct functional segments: a locking element with locking projection, a magazine shaft with locking groove, and a trigger mechanism with safety cover, where each segment performs a specific safety function that collectively ensures reliable prevention of unintended firing
Solution Approach 2:
The patent applies different mechanical locking solutions to different critical locations: a locking element for the magazine shaft and a safety cover for the trigger mechanism, ensuring that each vulnerable point has appropriate mechanical protection tailored to its specific function
4Ease of manufacture
If an insert is used to block the magazine shaft, then the ease of manufacture increases and the device is simpler, but the ability to prevent magazine feeding and unauthorized use must be achieved through effective mechanical blocking
Solution Approach 1:
The patent designs the insert as a separate, independently manufacturable component with integrated locking elements that can be produced through simple manufacturing processes and then assembled into the magazine shaft, balancing ease of manufacture with effective blocking functionality
Solution Approach 2:
The insert acts as an intermediary component between the magazine shaft and the locking mechanism, providing a simple interface that enables reliable mechanical blocking while maintaining ease of manufacture and assembly
