Single-Actuation Goggle Mounting for 3-Axis Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional goggle assemblies require multiple adjustment mechanisms for rotational and translational movement, increasing training and setup time, weight, and complexity, necessitating a simpler and more efficient positioning system.
Innovation Solution
A single actuation goggle positioning mounting assembly that allows movement in three independent directions using a single mechanism, integrated with goggles or a helmet, utilizing sliding mechanisms, floating friction-based wire/brake mechanisms, or floating mechanical brake-based mechanisms to provide up/down, fore/aft, and tilt adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple adjustment mechanisms are used for each degree of freedom, then positioning precision is improved, but device complexity and weight increase
Solution Approach 1:
The patent combines multiple adjustment mechanisms into a single integrated mechanism that controls all three degrees of freedom (fore/aft, up/down, and tilt) through one actuator. This merging approach maintains positioning precision while reducing device complexity and weight by eliminating redundant mechanical components, adjustment interfaces, and control systems.
Solution Approach 2:
The single actuation mechanism is designed to perform multiple functions simultaneously, controlling fore/aft movement, up/down movement, and tilt adjustment through one universal interface. This multi-functional design reduces the number of components needed while maintaining the ability to precisely adjust goggles in all required directions.
2Adaptability or versatility
If multiple adjustment mechanisms are used for each degree of freedom, then positioning capability is improved, but training and setup time increase
Solution Approach 1:
By merging multiple adjustment mechanisms into a single actuation system, the patent reduces the number of adjustment interfaces from three separate mechanisms to one unified control. This simplification maintains full positioning capability while reducing training time needed to learn the adjustment system and decreasing setup time in the field.
Solution Approach 2:
The patent creates a homogeneous adjustment interface where a single type of actuator controls all positioning functions, rather than requiring users to learn and operate three different adjustment mechanisms. This uniformity reduces cognitive load and training requirements while maintaining comprehensive positioning capability.
3Measurement precision
If multiple adjustment mechanisms are used, then movement control precision is improved, but overall weight increases
Solution Approach 1:
The patent merges multiple separate adjustment mechanisms into a single integrated actuation system, eliminating redundant motors, gears, control electronics, and mounting hardware. This consolidation maintains movement control precision across all three degrees of freedom while significantly reducing the overall weight of the mounting assembly.
Solution Approach 2:
The patent extracts and removes unnecessary duplicate components from the system, keeping only the essential single actuation mechanism needed to control all positioning functions. This extraction of redundant elements reduces weight while preserving the ability to precisely control goggle movement in all required directions.
4Adaptability or versatility
If multiple adjustment mechanisms are used, then positioning flexibility is improved, but adjustment time in field increases
Solution Approach 1:
By combining multiple adjustment mechanisms into one unified actuation system, the patent enables all positioning adjustments (fore/aft, up/down, tilt) to be made through a single interface. This merging reduces the time required to adjust goggles in the field while maintaining full positioning flexibility, as users no longer need to sequentially operate three separate mechanisms.
Solution Approach 2:
The single actuation mechanism is designed to perform all necessary positioning adjustments through one preliminary action, rather than requiring multiple separate adjustment steps. This preliminary action approach allows users to quickly set up and adjust goggles in the field without the time-consuming process of operating multiple independent adjustment mechanisms.

AI summary
A mounting device having a mounting assembly for mounting a pair of goggles to a helmet is provided. The mounting assembly is configured to provide at least three degrees of freedom of movement using one or more actuation mechanisms for locking and unlocking a position of the mounting device. The number of actuation mechanisms is less than a number of degrees of freedom. In some aspects, the number of actuation mechanisms is one. A rotation base connects the mounting assembly to the helmet, and a goggle linkage connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism, and a floating friction brake mechanism, are provided.
