Solution Overview

Problem

Users of head-mounted display devices for virtual reality face inconvenience when switching between virtual and real vision fields, as they must remove the device, which can damage glasses or skin and requires readjustment upon re-use.

Innovation Solution

A head-mounted display device with a connecting rod module and fixing rack system that allows the display module to be quickly removed and repositioned using a sliding mechanism with arc-shaped ribs and a torsion spring, enabling rapid transition between virtual and real vision fields without the need for device readjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user removes the head-mounted display device to switch between virtual and real vision fields, then the user can change the sight line, but the device must be taken off and readjusted each time, causing inconvenience and reducing usability

Engineering Contradiction:
Improveease of switching between virtual and real vision fieldsVSAvoidtime for device removal and readjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements a dynamic adjustment mechanism that allows the display module to move between a first position (covering eyes for virtual reality) and a second position (away from eyes for real vision). The connecting rod module with sliding member and arc-shaped rib enables rapid positional transition without removing the entire device, making the system adaptable to different usage states.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display device is segmented into a wearable device portion and a separately adjustable display module. This segmentation allows the display module to be independently positioned and adjusted relative to the wearable device, enabling quick switching between virtual and real vision fields without affecting the entire device structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the display module is fixedly attached to the wearable device, then the structure is simple, but the user cannot quickly switch between virtual and real vision fields

Engineering Contradiction:
Improveability to switch between virtual and real vision fieldsVSAvoidcomplexity of display module positioning mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms the fixed connection into a dynamic adjustable connection using the connecting rod module. The sliding member moving along the arc-shaped rib creates a mechanical linkage that provides multiple positions (first position for virtual reality, second position for real vision) while maintaining structural integration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connecting rod module acts as an intermediary mechanism between the wearable device and display module. It provides the necessary mechanical interface for positional adjustment, mediating between the fixed wearable device structure and the movable display module requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Speed

If the display module is rapidly removed and repositioned, then switching between virtual and real vision fields is convenient, but the mechanism becomes more complex

Engineering Contradiction:
Improvespeed of switching between virtual and real vision fieldsVSAvoidcomplexity of connecting rod module
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The connecting rod module with sliding member and arc-shaped rib creates a dynamic mechanical system that enables rapid positioning. The arc-shaped rib guides the sliding member along a predetermined path, allowing quick transition between positions through simple sliding motion rather than complex multi-step adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The arc-shaped rib introduces a curved geometric element that guides the sliding member's motion path. This curved geometry simplifies the adjustment mechanism by providing a predetermined rotational arc path, enabling rapid positioning without complex control systems.

Inventive Principle:
Principle #14Spheroidality (Curvature)
