Modular Head-Mountable Device Fit Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mountable devices require customization to fit different facial features, making them costly and impractical to tailor each device for individual users, as existing solutions lack modular adjustment capabilities to accommodate varying facial structures effectively.
Innovation Solution
The integration of modular assemblies, including a light seal module and a coupling module with adjustable features, allows for customizable fit adjustments without the need for extensive customization or a wide variety of sizes, enabling optimal alignment and comfort for users with diverse facial features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If head-mountable devices are customized to fit different facial features, then user comfort and fit quality improve, but manufacturing cost and device complexity increase
Solution Approach 1:
The head-mountable device is divided into multiple modular assemblies including a first assembly with adjustable features for facial feature adjustment, a second assembly for additional customization, and a third assembly completing the head-mounted structure. This segmentation allows individual modules to be adjusted independently to fit different facial features without requiring complete device customization.
Solution Approach 2:
The device incorporates adjustable features that allow dynamic modification of the modular assemblies during use. Users can adjust the position and configuration of the assemblies to adapt to different facial structures, enabling the device to change its form factor dynamically rather than requiring multiple fixed configurations.
2Adaptability or versatility
If multiple device sizes and configurations are produced to accommodate various facial structures, then adaptability improves, but manufacturing cost and inventory complexity increase
Solution Approach 1:
The modular assemblies are designed with universal interfaces and standardized components that can be configured in multiple ways to accommodate different facial structures. The same basic assemblies can serve multiple users with different face shapes by adjusting the configurable features, eliminating the need to manufacture separate devices for each facial type.
Solution Approach 2:
By segmenting the device into interchangeable modular assemblies, the system allows a single base unit to be paired with different configured assemblies or adjusted in various positions to fit different users, reducing the need for multiple complete device variants.
3Ease of manufacture
If fixed-size head-mountable devices are manufactured, then manufacturing simplicity is maintained, but fit quality and user comfort deteriorate for users with non-standard facial features
Solution Approach 1:
The modular assemblies incorporate adjustable features that enable the device to dynamically adapt its configuration to match different facial structures. Users can modify the position and orientation of assemblies during setup, allowing a single manufactured device to achieve proper fit for various face shapes without requiring multiple fixed-size variants.
Solution Approach 2:
The device allows adjustment of key geometric parameters such as assembly spacing, angle, and position to accommodate different facial dimensions. These parameter changes enable the same physical device to be optimized for different users through simple adjustments rather than manufacturing different sizes.

AI summary
A head-mountable device can include modules that provide fit adjustment capabilities when assembled together. By providing head-mountable devices with modular features, certain modules can provide fit adjustment capabilities without requiring other modules to be custom designed or available in a wide variety of sizes and/or shapes. For example, a light seal module that provides engagement of a user's face and transmits light from a display element can be coupled to an HMD module. The coupling module that couples the light seal to the HMD module can be provided in a wide variety of sizes and/or shapes to allow a user to select an appropriate one for optimal alignment of an HMD module. Additionally or alternatively, a light seal module can be provided with manual and/or automated adjustment capabilities to achieve the desired fit.
