Firearm Accessory Coupling with Resilient Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm accessory mounting systems require multiple steps and can loosen during operation, making them difficult to mount quickly with one hand and prone to unintentional detachment.
Innovation Solution
A coupling system with equal numbers of threaded and unthreaded portions, arranged at specific angles, and a resilient lock element with a protruding part that snaps into recesses to secure the connection, allowing for quick and secure attachment and detachment with one-hand axial and rotational movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional accessory mounting systems are used, then the accessory can be mounted on the firearm barrel, but the mounting process requires multiple steps and cannot be easily accomplished with one hand
Solution Approach 1:
The coupling device is divided into a female member with threaded portions and a male member with corresponding threads, allowing the accessory to be segmented into modular components that can be independently mounted and adjusted on the firearm barrel
Solution Approach 2:
The coupling device incorporates a resilient lock element that can dynamically transition between locked and unlocked states, enabling quick one-handed operation where the accessory can be rapidly mounted or dismounted by simply pushing the lock element to release the threading engagement
2Reliability
If traditional accessory mounting systems are used, then the accessory can be attached to the barrel, but the coupling may loosen unintentionally during operation
Solution Approach 1:
The resilient lock element is pre-positioned to engage with the threaded portions of the male and female members, creating a preliminary locking action that prevents unintentional loosening during firearm operation while maintaining the ability for intentional quick release when needed
Solution Approach 2:
The coupling device uses self-locking threaded portions where the threads themselves provide the locking mechanism, eliminating the need for separate locking components or complex fastening procedures while maintaining secure attachment during operation
3Reliability
If a secure locking mechanism is implemented, then the coupling prevents unintentional loosening, but the device complexity increases
Solution Approach 1:
The locking function is merged with the threading structure itself, where the threaded portions of the male and female members serve both the fastening and locking functions simultaneously, eliminating the need for separate locking mechanisms and reducing overall device complexity
Solution Approach 2:
The coupling device employs self-locking threaded portions that automatically secure the accessory during operation without requiring external locking components, and the resilient lock element serves multiple functions including positioning, locking, and enabling quick release, thereby simplifying the overall mechanism
