Optical Device Mount Interface With Play Compensation and Secure Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current land helmet interfaces and imprinted elements often suffer from significant mechanical inequalities during assembly, leading to mechanical play that compromises the stability of optical devices like night vision goggles, causing disengagement and premature wear, and lacks universal compatibility with different manufacturers' products.
Innovation Solution
The introduction of an interface and imprinted element system that includes compensating means, such as adjustable blocks and screws, to accommodate mechanical play in multiple directions, ensuring stable positioning and compatibility with various imprinted elements, and enhanced locking mechanisms requiring dual actions for release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional land helmet interfaces are used without compensating means, then the device structure remains simple, but mechanical play occurs during assembly leading to instability of optical devices
Solution Approach 1:
The patent introduces adjustable compensating means (screws, blocks) that allow modification of geometric parameters of the interface assembly. These compensating means can be adjusted to change the position and orientation parameters, thereby compensating for mechanical inequalities and eliminating mechanical play between the interface and imprinted element.
Solution Approach 2:
The compensating means are designed to be self-adjusting, allowing the user to eliminate mechanical play through simple adjustment of the screws or blocks. The system serves itself by providing built-in compensation capability that activates when mechanical inequalities are detected, without requiring external intervention or complex control systems.
2Reliability
If traditional locking mechanisms are used, then the release operation is simple and quick, but unintentional release may occur during use
Solution Approach 1:
The locking mechanism transitions from a static single-action system to a dynamic two-action system. The release requires two distinct actions (such as pressing two buttons simultaneously or a button sequence), creating a dynamic control system that prevents accidental activation while maintaining ease of intentional release.
Solution Approach 2:
The system requires preliminary confirmation through a second action before releasing the lock. This preliminary action serves as a verification step that ensures the user intends to release the optical device, preventing unintentional release while keeping the actual release mechanism simple once confirmed.
3Adaptability or versatility
If interfaces are designed for specific manufacturers' imprinted elements, then precise fit is achieved, but compatibility with other manufacturers' products is lost
Solution Approach 1:
The interface is designed with universal compensating means that can accommodate variations in imprinted element dimensions and tolerances from different manufacturers. The adjustable blocks and screws provide a range of adjustment capabilities that allow the same interface to achieve precise fit with multiple types of imprinted elements, making the system universally compatible.
Solution Approach 2:
The interface is divided into modular components including separate compensating means that can be independently adjusted. This segmentation allows each component to be optimized for specific compatibility requirements while maintaining overall system versatility across different manufacturer specifications.

AI summary
The invention relates to an interface for connecting an optical device and a mobile support which cooperates securely with an imprinted element, the interface having a base arranged to be inserted into the imprinted element, the base being a hollow body. The base accommodates mechanical play compensating structures which are movably mounted within the hollow body so as to project and are arranged in order to bear against a wall of the imprinted element.
