Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional head-mounted displays (HMDs) obstruct the user's view of the real-world environment, making it difficult to interact with real-world objects, and existing diffusion models lack effective methods for ensuring privacy and computational efficiency in image generation.

Innovation Solution

The HMD device provides a substantially unobstructed view of the real-world environment by positioning the display unit in the top portion of the user's field of view and using a housing that allows for interaction with both virtual and real-world objects, while the improved diffusion models employ differential privacy and retrieval-augmentation techniques to train high-quality text-to-image generative models.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display unit is positioned to cover the user's field of view for immersive virtual reality, then the virtual reality experience is improved, but the user's ability to view and interact with the real-world environment deteriorates

Engineering Contradiction:

Improvevirtual reality immersionVSAvoidinteraction with real-world objects

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically switches between immersive VR mode and augmented reality mode based on user interaction needs. The display unit can transition from covering the entire field of view to providing unobstructed views of the real world, allowing users to interact with real-world objects while maintaining VR functionality when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The field of view is segmented into different zones: a top portion for virtual content display and a bottom portion for unobstructed real-world viewing. This spatial segmentation allows simultaneous access to both virtual and real-world environments without requiring full immersion or complete removal of the device.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If conventional diffusion models are used for image generation, then computational simplicity is maintained, but privacy protection and computational efficiency deteriorate

Engineering Contradiction:

Improvemodel simplicityVSAvoidprivacy protection

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

A retrieval-augmented generation component is introduced as an intermediary between the diffusion model and the output. This intermediary retrieves relevant information from a database and guides the diffusion process, enabling privacy protection through differential privacy mechanisms while maintaining computational efficiency and high-quality image generation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Illumination intensity

If the display unit obstructs the user's view for virtual content delivery, then virtual content visibility is improved, but real-world object interaction deteriorates

Engineering Contradiction:

Improvevirtual content visibilityVSAvoidreal-world interaction

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The display unit alternates between providing full virtual content coverage and providing unobstructed real-world views. This periodic switching allows users to maintain awareness of the real environment for interaction while periodically accessing immersive virtual content, balancing both requirements.

Inventive Principle:

Principle #19Periodic action

AI summary

A method for improved heat discharge may include sensing a temperature value of a battery circuit; activating a heat dissipation element within the battery circuit when the temperature value reaches a threshold; discharging heat from the battery circuit via the activated heat dissipation element; and deactivating the heat dissipation element when the temperature value falls below the threshold.
