A T-shaped clamp device with a mounting base, pressure plate, cam member, and locking tab system that allows for adjustable clamping pressure and secure attachment to Picatinny or floating rail structures, featuring a pivoting cam mechanism and sliding locking tab for enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional clamp device is used for firearm mounting rail systems, then the accessory can be attached to the rail, but the attachment becomes unstable under recoil forces and misalignment occurs
Solution Approach 1:
The clamp device employs a dynamic cam mechanism that allows the pressure plate to pivot and adjust automatically under recoil forces. The cam body rotates within the arms, enabling the pressure plate to maintain optimal contact pressure with the rail surface during dynamic operation, preventing both detachment and misalignment under recoil conditions
Solution Approach 2:
The device changes the clamping pressure parameter dynamically through the cam mechanism. As the cam body rotates, it modifies the distance between the pressure plate and rail surface, automatically adjusting the clamping force to maintain stable attachment while preventing excessive pressure that could cause misalignment or damage to the rail system
2Reliability
If a simple clamp mechanism is used, then the device structure remains simple, but the clamping pressure becomes inconsistent leading to potential detachment
Solution Approach 1:
The cam mechanism provides dynamic adjustment of clamping pressure through rotational movement of the cam body within the arms. This simple rotational motion automatically compensates for variations in rail surface conditions and accessory positioning, ensuring consistent clamping pressure without requiring complex control systems or multiple adjustment mechanisms
Solution Approach 2:
The cam mechanism is designed to self-adjust the clamping pressure based on the natural rotation caused by attachment and detachment operations. The geometry of the cam body and arms creates an automatic pressure regulation system that maintains consistent clamping force without requiring external control inputs or complex feedback mechanisms
3Reliability
If a secure attachment system is implemented, then the accessory remains firmly attached during recoil, but the removal process becomes difficult and time-consuming
Solution Approach 1:
The cam mechanism enables easy removal by allowing the pressure plate to pivot outward when the cam body rotates to the release position. The same dynamic mechanism that provides secure attachment during firing automatically facilitates quick removal by reversing the cam rotation, eliminating the need for separate release mechanisms or excessive force to detach the accessory
4Reliability
If the pressure plate is fixed in position, then the manufacturing process remains simple, but the clamping pressure cannot be adjusted leading to instability
Solution Approach 1:
The pressure plate is designed to pivot on a pivot pin rather than being fixed, creating a simple hinge joint that allows automatic adjustment of clamping pressure. This pivot connection is manufactured as a basic mechanical joint requiring minimal assembly steps while enabling the pressure plate to adapt its position and maintain optimal contact pressure with the rail surface under various operating conditions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure, adjustable, and reliable attachment system that maintains accessory orientation and facilitates easy removal, addressing recoil-induced instability and misalignment issues while ensuring consistent clamping pressure.
Implementation Method 1
A cam member has a lever attached to a cam body, the cam body pivotally mounted between the first and second arms. The cam body bears against the pressure plate to cause sliding movement of the pressure plate in response to pivoting movement of the lever.
Implementation Method 2
A locking tab is slidably attached to the pressure plate, and is slidable between a locked position and an unlocked position. The locking tab has a lip engaging the cam member to prevent pivoting movement of the cam body out of a clamped position when the locking tab is in the locked position.
Implementation Method 3
A hook is disposed on a first transverse side of the mounting surface. The hook is configured to engage a first transverse side of the mounting structure.
