Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional goggle assemblies require multiple adjustment mechanisms, increasing training and setup time and overall weight, and are often manufactured separately from the goggle or helmet, leading to further delays.

Innovation Solution

A single actuation mechanism integrated into either the goggle or helmet allows for three degrees of freedom of movement (up/down, fore/aft, and tilt) using a sliding or floating friction-based mechanism, reducing the number of components and simplifying the adjustment process.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:

Improvepositioning precisionVSAvoidnumber of adjustment mechanisms

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple adjustment mechanisms into a single integrated positioning assembly that can adjust goggles in multiple directions (fore/aft, vertical, and rotation) using one mechanism rather than separate mechanisms for each degree of freedom

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The positioning assembly is designed to perform multiple adjustment functions simultaneously, allowing a single mechanism to control fore/aft movement, vertical positioning, and rotational adjustment of the goggles

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If multiple adjustment mechanisms are used for each degree of freedom, then positioning control is improved, but training and setup time increase

Engineering Contradiction:

Improvepositioning controlVSAvoidtraining and setup time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent integrates multiple adjustment functions into a single positioning assembly that requires only one mechanism to be operated, eliminating the need for users to learn and coordinate multiple separate adjustment mechanisms

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The positioning assembly is designed to be automatically integrated with the goggle and helmet systems, eliminating separate setup steps and allowing the device to be ready for use immediately upon assembly

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple adjustment mechanisms are used, then adjustment range is improved, but overall weight increases

Engineering Contradiction:

Improveadjustment rangeVSAvoidoverall weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent consolidates multiple adjustment mechanisms into a single lightweight positioning assembly that provides comprehensive adjustment capability across multiple degrees of freedom without the cumulative weight of separate mechanisms

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The positioning assembly is designed as a multi-functional unit that achieves broad adjustment range through integrated mechanical design rather than through multiple separate heavy mechanisms

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If goggle positioning assembly is manufactured separately from goggle or helmet, then manufacturing flexibility is improved, but integration time and setup delays increase

Engineering Contradiction:

Improvemanufacturing flexibilityVSAvoidintegration time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The patent integrates the positioning assembly directly into the goggle structure or helmet mounting system, creating a unified component that eliminates separate integration steps and reduces setup time

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The positioning assembly is pre-integrated with either the goggle or helmet during manufacturing, so that the integration work is completed beforehand and no additional assembly steps are required during field setup

Inventive Principle:

Principle #10Preliminary action

AI summary

A mounting device having a mounting assembly (20) for mounting a pair of goggles (30) to a helmet (10) 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 (302) connects the mounting assembly to the helmet, and a goggle linkage (307) connects the mounting assembly to the goggles. Various single actuation mechanisms, including a sliding mechanism, a friction-based wire/brake mechanism (50), and a floating friction brake mechanism, are provided.
