Solution Overview

Problem

Current VR training methods for construction sites are costly, require specific locations, and can only train one person at a time, as they necessitate expensive equipment installation and sequential training due to the limitations of HMD terminals.

Innovation Solution

A VR video management system that allows simultaneous training of multiple users using HMD terminals synchronized with a manager terminal, enabling real-time control and management of VR videos without the need for separate equipment, allowing training anywhere without a dedicated space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional VR training equipment is installed, then immersive training experience is improved, but installation cost and device complexity increase

Engineering Contradiction:
Improveimmersive training experienceVSAvoidtraining equipment installation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses video recording technology to capture real-world training scenarios and creates virtual replicas that can be viewed through HMD terminals. This copying approach eliminates the need for complex physical VR training equipment while maintaining immersive training experience, as the virtual environment is created by recording and replaying real-world events rather than requiring sophisticated virtual reality hardware infrastructure.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical VR training equipment with a video-based system. Instead of using complex motion capture, virtual reality engines, and specialized hardware, the system uses simple video recording and playback mechanisms to achieve training objectives. This substitution dramatically reduces device complexity and installation requirements while maintaining training effectiveness.

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

2Reliability

If HMD terminals are used for sequential training, then training depth is improved, but training time increases

Engineering Contradiction:
Improvetraining depthVSAvoidtraining time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the training process into multiple parallel sessions that can occur simultaneously. By recording different training scenarios and making them available through HMD terminals, multiple trainees can engage with training content at the same time rather than sequentially. This segmentation of training content into independent video modules enables parallel processing of training, significantly reducing total training time while maintaining depth through comprehensive video coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent enables continuous training by allowing multiple trainees to simultaneously view training videos through HMD terminals. The video recording system captures training events continuously, and the playback system can operate continuously for multiple users without interruption. This eliminates the idle time between sequential trainings and maintains continuous useful action throughout the training period.

Inventive Principle:
Principle #20Continuity of useful action

3Reliability

If dedicated training space is required, then training safety is improved, but adaptability decreases

Engineering Contradiction:
Improvetraining safetyVSAvoidtraining location flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates virtual copies of training environments through video recording, allowing trainees to experience safe training scenarios without being physically present in dedicated training spaces. The recorded videos capture safety-critical events and procedures that can be reviewed safely in any location, eliminating the need for specialized training facilities while maintaining training safety standards.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent transitions training from a physical spatial constraint to a temporal and digital dimension. Instead of requiring a specific physical location for training, the system uses video recording to capture training events and delivers them through HMD terminals. This dimensional shift from physical to digital space allows training to occur anywhere, greatly enhancing adaptability while maintaining safety through controlled video playback.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
