Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing head-mountable display systems face challenges in providing immersive virtual and mixed reality experiences due to limitations in display configuration, user comfort, and effective light management, particularly in blocking external light from reaching the user's eyes.

Innovation Solution

A head-mountable display device with a housing featuring a front and rear opening, multiple display screens oriented in different directions, securement straps with electronic components, and a flexible textile material securement band, along with a light seal to block external light, and an adjustment mechanism for positioning the display screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If multiple display screens are added to provide immersive virtual and mixed reality experiences, then the display quality and immersion are improved, but the device complexity and structural configuration increase

Engineering Contradiction:

Improvedisplay qualityVSAvoiddisplay configuration

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The display system is divided into multiple independent display screens (first display screen, second display screen, third display screen) that can be separately configured and positioned. Each display screen is part of a modular display assembly that can be independently adjusted relative to the housing and to each other, allowing complex display configurations to be managed through modular segmentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces spatial arrangement in multiple dimensions by positioning display screens at different orientations and locations. The first display screen is oriented to project light in a first direction while the second and third display screens are oriented to direct light in a second direction opposite the first direction, creating a multi-dimensional display configuration that enhances immersion.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If display screens are positioned close to the user's eyes for immersion, then the virtual reality experience is improved, but external light may interfere with the display

Engineering Contradiction:

ImproveimmersionVSAvoidexternal light interference

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent addresses the harmful effect of external light by introducing a light seal that blocks external light from reaching the user's eyes. This light seal converts the potential harm of external light interference into a beneficial feature by actively preventing it, thereby enhancing the immersive display experience without compromising visibility.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Ease of operation

If securement straps with electronic components are added to provide customizable fit, then user comfort is improved, but the device complexity increases

Engineering Contradiction:

Improveuser comfortVSAvoidsecurement mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The securement straps are designed with multi-functionality, integrating both the securement function and electronic component housing into a single structure. The first securement strap and second securement strap each include electronic components, allowing the same structural element to serve both mechanical (securement) and electronic functions, thereby reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the securement function with electronic component integration by incorporating electronic components directly into the securement straps. The first securement strap includes a first electronic component and the second securement strap includes a second electronic component, combining what would traditionally be separate elements into unified structures.

Inventive Principle:

Principle #5Merging (Combining)

4Object-affected harmful factors

If a light seal is added to block external light, then light management is improved, but the device complexity and material requirements increase

Engineering Contradiction:

Improvelight blockingVSAvoidlight management structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The light seal is implemented as a flexible structure that can conform to the housing geometry while effectively blocking external light. This flexible approach allows the light seal to be integrated into the existing device structure without requiring complex rigid frameworks, reducing overall device complexity while maintaining effective light management.

Inventive Principle:

Principle #30Flexible shells and thin films
