Membrane-Covered Frame for Head-Mounted Display Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display housings often compromise between aesthetics and functionality, lacking lightweight and durable designs that effectively protect internal components while allowing for clear tracking of markers by cameras.
Innovation Solution
The use of a membrane-covered frame with a flexible membrane that encloses the housing assembly, featuring a contoured frame with loops and beams, providing a lightweight and aesthetically pleasing enclosure that maintains component protection and allows infrared transparency for tracking, with interchangeable membranes and frames for customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional rigid housing is used, then component protection is improved, but weight increases and aesthetics deteriorate
Solution Approach 1:
The patent applies a flexible membrane material to cover the frame structure, creating a lightweight enclosure that replaces traditional rigid housings. The membrane provides sufficient protection for internal components while dramatically reducing weight compared to solid housing materials, directly resolving the contradiction between protection and weight.
Solution Approach 2:
The housing assembly combines a rigid frame structure with a flexible membrane covering, creating a composite construction that leverages the strength of the frame for component protection while the thin membrane minimizes weight. This composite approach allows the housing to achieve both durability and lightness simultaneously.
2Reliability
If a solid housing enclosure is used, then component protection is improved, but infrared transparency for tracking deteriorates
Solution Approach 1:
The flexible membrane material is specifically selected to be translucent to infrared light, allowing tracking cameras to clearly detect markers through the housing. This thin film construction provides component protection while maintaining infrared transparency, eliminating the need for separate camera windows or openings in the housing.
Solution Approach 2:
The patent changes the optical parameters of the housing material by selecting a membrane that is translucent rather than opaque to infrared wavelengths. This parameter change allows the housing to simultaneously provide physical protection and maintain infrared transparency for accurate tracking without requiring additional modifications.
3Weight of moving object
If a lightweight membrane structure is used, then weight is reduced and aesthetics are improved, but manufacturing complexity increases
Solution Approach 1:
The housing is segmented into a separate frame structure and a removable membrane cover, allowing each component to be manufactured independently using optimized processes. The frame can be produced using standard fabrication methods while the membrane can be manufactured separately and then assembled, reducing overall manufacturing complexity despite the lightweight design.
Solution Approach 2:
The membrane cover serves multiple functions simultaneously: it provides structural enclosure, protects internal components, enables infrared tracking through its translucency, and offers aesthetic customization. This multi-functionality reduces the need for additional separate components, simplifying the overall assembly process despite the innovative design.
4Ease of manufacture
If a fixed housing design is used, then manufacturing is simplified, but adaptability for customization deteriorates
Solution Approach 1:
By separating the housing into a permanent frame and interchangeable membrane covers, the patent enables easy customization. Users can swap membranes with different colors, patterns, or material properties without replacing the entire housing or frame, providing high adaptability while keeping the base manufacturing process simple and standardized.
Solution Approach 2:
The housing design transitions from a static, fixed structure to a dynamic, reconfigurable system. The removable and interchangeable membrane covers allow the housing to adapt to different user preferences and requirements, enabling customization while maintaining a simple, standardized frame structure that is easy to manufacture.

AI summary
Technology is provided for a housing assembly with a membrane-covered frame for use with head mounted displays. The head mounted display includes a housing assembly having a frame. The frame includes a first loop structure, a second loop structure offset along a central axis from the first loop structure, and a plurality of beams extending between the first loop structure and the second loop structure. A flexible membrane extends around the frame to enclose the housing assembly and the components therein. One or more display devices are positioned within the housing assembly, and a strap assembly connects to the housing assembly for supporting the head mounted display on a user's head.
