Attenuated Rail Grabber for Optical Sight Shock Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weapons, such as guns, generate severe shocks that can damage connected devices like optical devices due to the direct transmission of these shocks.
Innovation Solution
An attenuated rail grabber is mounted between the weapon and the optical device, comprising a rigid support member and spring features that allow relative movement, reducing shock transmission from 1500 to 400 g's.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid mounting structure is used to attach the optical device to the weapon, then the device is securely mounted and maintains alignment, but the optical device is directly exposed to severe shock from the weapon
Solution Approach 1:
The patent introduces a shock attenuator as an intermediary component between the rigid mounting structure and the optical device. This attenuator absorbs and dissipates shock energy, preventing direct transmission to the optical device while maintaining the security and alignment provided by the rigid mounting structure.
Solution Approach 2:
The shock attenuator is pre-installed in the mounting structure to cushion shock before it reaches the optical device. The attenuator is positioned to intercept and absorb shock waves generated by the weapon, protecting the optical device in advance from harmful shock exposure.
2Object-affected harmful factors
If a shock attenuator is added between the weapon and the optical device, then shock transmission is reduced, but the device complexity increases
Solution Approach 1:
The shock attenuator is merged with the mounting structure, combining the functions of shock attenuation and device mounting into a single integrated assembly. This integration reduces the number of separate components and simplifies the overall structure while maintaining shock protection capabilities.
Solution Approach 2:
The mounting structure is designed to serve multiple functions: providing secure mounting, maintaining alignment, and attenuating shock. By making the mounting structure multi-functional, the patent reduces the need for additional separate shock attenuation components, thereby reducing overall device complexity.
3Object-affected harmful factors
If a shock attenuator is added between the weapon and the optical device, then the optical device is protected from shock, but the system height increases
Solution Approach 1:
The shock attenuator is nested within the existing mounting structure, fitting into the available space without adding external protrusions. This nesting approach allows the attenuator to provide shock protection while maintaining a compact form factor and preventing increase in system height.
Solution Approach 2:
The shock attenuator is designed to operate in a dimension parallel to the mounting structure rather than adding height in the vertical dimension. By arranging the attenuator mechanism sideways or in-plane with the mounting structure, the patent provides shock protection without increasing the overall height of the system.
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 attenuated rail grabber effectively isolates the optical device from weapon shocks, protecting its functionality while maintaining boresight alignment and reducing wear, without adding height to the system.
Implementation Method 1
The attenuated rail grabber includes a first spring feature coupled to the rigid support member. The first spring feature includes a fore mounting tab having a fore fastener aperture. The attenuated rail grabber also includes a second spring feature coupled to the rigid support member. The second spring feature includes an aft mounting tab having an aft fastener aperture.
Implementation Method 2
The first spring feature and the second spring feature can allow for relative movement between the rigid support member and the weapon. The g load can be reduced from 1500 to 400 g's.
