Solution Overview

Problem

Existing head-mounted displays for augmented and virtual reality face challenges in sanitation and user size matching due to sensitive electronics and optics, making cleaning and adjustment difficult, especially in public settings where hygiene is a concern.

Innovation Solution

The system is divided into two sections, allowing the face-contacting section to be easily cleaned and sanitized separately from the section containing sensitive electronics and optics, with customizable frames to fit different users' sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the head mounted display is designed as a single integrated unit, then structural simplicity is maintained, but sanitation and cleaning become difficult due to sensitive electronics and optics

Engineering Contradiction:

Improvesanitation and cleaningVSAvoidsystem structure

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The head mounted display is divided into two separate sections: a face-contacting section (glasses portion) and an electronics section (headset portion). This segmentation allows the face-contacting section to be easily removed and cleaned independently without exposing sensitive electronics to water or cleaning agents, thereby resolving the sanitation difficulty while maintaining reasonable structural simplicity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a single common frame is used to fit different user sizes, then device simplicity is maintained, but adaptability to different users is reduced

Engineering Contradiction:

Improveuser size matchingVSAvoidframe adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame is segmented into interchangeable components that can be selected or adjusted to fit different user sizes and face shapes. This allows the system to adapt to various users without requiring complex mechanical adjustment mechanisms built into a single common frame, thereby improving adaptability while keeping the device relatively simple.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the face-contacting section remains attached to the electronics section, then structural integrity is maintained, but cleaning and sanitation are compromised

Engineering Contradiction:

Improvestructural integrityVSAvoidcontamination and hygiene

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system is segmented into detachable sections where the face-contacting portion can be separated from the electronics section. This allows the face-contacting section to be easily removed for cleaning and sanitation, eliminating the risk of contamination while maintaining structural integrity during normal use through secure connection mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The face-contacting section is extracted as a separate removable component from the electronics section. This extraction enables independent cleaning and sanitation of the face-contacting section without exposing sensitive electronics to water or cleaning agents, thereby protecting against contamination while maintaining structural integrity during operation.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A system is presented in which a head mounted display is realized in two sections such that a section that comes in contact with the human face may be cleaned and sanitized independently of a section with sensitive electronic and optical components.
