Solution Overview

Problem

Existing head-mounted display devices are cumbersome for storage and prone to damage from external light, which can cause burns to the display screen, making them inconvenient to store and potentially reducing their service life.

Innovation Solution

A head-mounted display device with an adjustable shielding portion that changes its positional relationship with the main body to enable both head-wearing and light-shielding functions, using a connecting rod group and elastic wearing portions to facilitate easy storage and protection of internal components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the head-mounted display device includes a main body and head-wearing components such as straps to fix it on the user's head, then the head-wearing function is achieved, but the device becomes cumbersome and occupies large space for storage

Engineering Contradiction:
Improvehead-wearing functionVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The shielding portion is designed to be foldable and can be nested against the main body when not in use, similar to a nested doll structure. This allows the head-wearing components to be compacted into a smaller volume for convenient storage while maintaining the full head-wearing function when deployed

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The shielding portion incorporates a foldable structure with connecting rods that allow dynamic adjustment between an extended position for head-wearing and a folded position for compact storage. This dynamic design enables the device to transition between functional and storage states, reducing storage volume while preserving reliability

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If external light照射 the display screen inside the main body after use, then the device can be stored openly, but the light causes burns to the display screen

Engineering Contradiction:
Improvestorage convenienceVSAvoidlight damage to display screen
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The shielding portion is designed to automatically or manually cover the display screen before the device is stored or placed in bright environments. This preliminary protective action prevents external light from reaching and damaging the display screen, eliminating the harmful effect while maintaining storage convenience

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The shielding portion acts as an intermediary barrier between external light and the display screen. When deployed, it physically blocks light paths to the screen; when folded, it allows normal operation. This mediator structure enables safe storage without requiring special storage conditions

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the shielding portion is always close to the main body to protect from light, then the display screen is protected, but the head-wearing function cannot be achieved

Engineering Contradiction:
Improvelight protectionVSAvoidhead-wearing function
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The foldable shielding portion can dynamically change its position between close to the main body (for protection) and extended away from the main body (for head-wearing). This dynamic positioning allows the device to switch between protective mode and functional mode, satisfying both requirements at different times

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shielding portion is segmented into multiple sections connected by connecting rods, allowing independent adjustment of each segment. This segmentation enables the shielding to cover the display screen when needed while still allowing the head-wearing components to be properly positioned for use

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is a head-mounted display device, including a main body portion with an ocular lens, and further including an adjustment assembly which is connected to the main body portion and is used for adjusting a positional relationship with respect to the main body portion, wherein the adjustment assembly includes a shielding portion; when the adjustment assembly is in a first operating state, the shielding portion is away from the main body portion for realizing a wearing function; and when the adjustment assembly is in a second operating state, the shielding portion is close to the main body portion for shielding the ocular lens, thereby realizing convenient and quick storage and safekeeping, and facilitating the prolonging of the service life of the head-mounted display device.
