Solution Overview

Problem

Current VR training systems lack the ability to provide realistic tactile and environmental interaction, limiting the effectiveness of training scenarios, particularly in environments requiring physical interaction with virtual structures.

Innovation Solution

An XR training server that generates and displays XR training data, incorporating preprocessor, content producer, and interaction part to create realistic training scenarios with interactive virtual objects and environments, using template data with assigned attribute information to simulate physical interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If VR provides only visual and auditory stimulation, then the training can be simplified and safer, but the completeness of training is reduced because users cannot interact with structures

Engineering Contradiction:
Improvetraining safetyVSAvoidtraining completeness
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces traditional mechanical physical contact with haptic feedback technology. The haptic feedback device generates tactile sensations through controlled vibration and force, allowing users to perceive and interact with virtual structures without actual physical contact. This substitution maintains safety while restoring training completeness through realistic tactile interaction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the parameter of interaction from purely sensory (visual/auditory) to multi-sensory by introducing tactile feedback. The haptic feedback device modifies the physical state of the user's hand through vibration frequency and force magnitude, enabling realistic interaction with virtual objects and structures during training.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If VR uses only audio-visual stimulation, then the system complexity is reduced, but the ability to simulate physical interactions with structures is lost

Engineering Contradiction:
Improvesystem complexityVSAvoidinteraction realism
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent substitutes complex mechanical interaction systems with a haptic feedback-based virtual interaction system. Instead of requiring physical structures for training, the system uses virtual structures combined with haptic feedback to simulate physical interactions, reducing overall system complexity while maintaining interaction realism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a copy of physical interaction through haptic feedback. The haptic feedback device reproduces tactile sensations such as texture, temperature, and force, allowing users to perceive virtual structures as if they were real objects, thereby maintaining interaction realism without requiring actual physical structures.

Inventive Principle:
Principle #26Copying

3Manufacturing precision

If XR training data is generated using template data with attribute information, then the training scenario realism is improved, but the data processing complexity increases

Engineering Contradiction:
Improvetraining scenario realismVSAvoiddata processing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary processing by converting real-world images into template data with assigned attribute information before generating training scenarios. This pre-processing step extracts essential features and assigns properties to objects, simplifying the subsequent scenario generation process while maintaining high realism in the training scenarios.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the data processing into distinct stages: image acquisition, template data generation with attribute assignment, and training scenario creation. This segmentation allows each stage to be optimized independently, reducing overall processing complexity while maintaining training scenario realism through structured data handling.

Inventive Principle:
Principle #1Segmentation
