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, which complicates the positioning of head-mounted goggles.
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 significantly reducing device complexity and weight compared to having separate mechanisms for each degree of freedom
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 unified system. This multi-functional design eliminates the need for multiple specialized mechanisms while maintaining full positioning capability
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 controls the user must learn and manipulate. This simplification maintains full positioning capability while significantly reducing training requirements and setup time in the field
3Ease of operation
If multiple adjustment mechanisms are used for each degree of freedom, then positioning control is improved, but weight increases
Solution Approach 1:
The patent merges multiple separate adjustment mechanisms into a single integrated actuation system, which maintains full positioning control capability while significantly reducing the overall weight of the mounting assembly by eliminating redundant components
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 single actuation mechanism reduces training and setup time, minimizes weight, and simplifies the interface, enabling faster and more efficient positioning of goggles while maintaining three degrees of freedom.
Implementation Method 1
a floating friction-based wire/brake mechanism. When the single actuation mechanism is actuated, the goggles may undergo movement in three directions, namely up/down, fore/aft, and tilt
Implementation Method 2
the goggle positioning mounting assembly includes a sliding mechanism with a plurality of sliding elements. When the single actuation mechanism is actuated, the goggles may undergo movement in three directions
Implementation Method 3
the mounting assembly comprises a tension module comprising at least one spring and at least one wire

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.
