Adjustable Facial Interface for Head-Mounted Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality headsets often fail to comfortably fit users with varying head or face shapes, and those who wear glasses, as they require replacement facial interface cushions for proper adjustment.
Innovation Solution
An adjustable facial-interface system for head-mounted displays, featuring a facial interface with a positioning abutment surface and a rotatable positioning member that can switch between extended and contracted holding positions, allowing for customizable fit without the need for replacement cushions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size facial interface cushion is used, then the structure is simple, but it cannot accommodate users with various head or face shapes or those who wear glasses
Solution Approach 1:
The patent applies the dynamics principle by making the facial interface cushion position adjustable through a movable cushion carrier that can be repositioned along the head-mounted display frame. This allows the cushion to dynamically adapt to different user face shapes and sizes, as well as accommodate glasses wearers, without requiring multiple replacement cushions. The adjustable mechanism enables the same cushion to serve multiple fitting purposes.
2Adaptability or versatility
If replacement facial interface cushions are required for proper adjustment, then the fit can be customized, but the device complexity and number of parts increase
Solution Approach 1:
The patent applies the universality principle by designing a single facial interface cushion that can be adjusted to fit multiple user types and face shapes. The cushion carrier mechanism allows one cushion to perform the function that would otherwise require multiple different-sized cushions, reducing the quantity of parts needed while maintaining fit customization capability.
3Adaptability or versatility
If the facial interface is fixed, then the structure is stable, but it cannot be adjusted for different users or accessories
Solution Approach 1:
The patent implements adjustability through a dynamic cushion carrier system that can be repositioned along the head-mounted display frame. This mechanical adjustment mechanism allows users to modify the cushion position to accommodate different face shapes, sizes, and accessories like glasses, while maintaining overall structural stability through the defined guide paths and mounting structures.

AI summary
A facial-interface system for a head-mounted display may include (1) a facial interface having a positioning abutment surface and (2) a facial-interface adjustment apparatus. The facial-interface adjustment apparatus may include a positioning member that is rotatable about a pivot, the positioning member comprising an extending surface and a contracting surface. The facial-interface adjustment apparatus may also include an actuation member that that is movable to rotate the positioning member about the pivot between (1) an extended holding position in which the extending surface of the positioning member faces and abuts the positioning abutment surface of the facial interface, and (2) a contracted holding position in which the contracting surface of the positioning member faces and abuts the positioning abutment surface of the facial interface. Various other systems, devices, and methods are also disclosed.
