Modular HMD Goggle Assembly for Custom Fit and Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head mountable display systems lack modularity and customization options to accommodate user preferences and various use cases, leading to discomfort and limited functionality.
Innovation Solution
A modular ergonomic goggle system with interchangeable components such as facial engagements, securements, and front covers that can be mixed and matched to fit different user preferences and use scenarios, enhancing comfort and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed design of head mountable display is used, then manufacturing and inventory management are simplified, but user comfort and adaptability to different use cases deteriorate
Solution Approach 1:
The head mountable display system is divided into distinct modular components: a display unit and multiple interchangeable facial engagements. Each facial engagement can be selectively coupled to the display unit, allowing users to swap components based on different use cases and preferences without replacing the entire system, thus improving adaptability while managing complexity through standardized interfaces
Solution Approach 2:
The display unit is designed with universal mounting structures that can accommodate multiple types of facial engagements. This multi-functionality allows a single display unit to serve various purposes (e.g., different activities, different users) by simply changing the facial engagement component, resolving the contradiction between versatility and complexity
2Ease of operation
If interchangeable components are introduced, then customization and user comfort improve, but device complexity and number of parts increase
Solution Approach 1:
The system separates the facial engagement components from the display unit, allowing independent selection and replacement of facial engagements based on comfort preferences. This segmentation enables users to optimize comfort without affecting the core display functionality, managing the increase in component number through clear functional separation
Solution Approach 2:
Different facial engagements provide varying parameters for user interaction and comfort (e.g., different contact points, pressure distributions, field of view). By allowing users to select among pre-designed facial engagements with different parameters, the system achieves customization without requiring users to design components themselves, balancing comfort improvement with manageable complexity

AI summary
A head mountable display (HMD) can include a display unit, a facial engagement that can be selectively coupled to the display unit, and a securement that can be selectively coupled to the display unit. The facial engagement can be configured to engage a face of a user, such as to fit the HMD to the user's face. The securement can be configured to position the facial engagement against the user's face, such as to position the display unit for viewing by the user. A first coupling can removably couple the facial engagement to the display unit for modularity. A second coupling can removably couple the securement to the display unit for modularity. The display unit, a first facial engagement, a second facial engagement, a first securement, and a second securement can be mixed and matched to configure the HMD based on user preference, form factor, or use.
