Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional training methods are used, then workers can learn from skilled workers by watching and learning, but it takes a long time to train new workers and skilled workers are insufficient
Solution Approach 1:
The patent creates a virtual copy of the secondary battery production plant using VR technology. This virtual replica allows trainees to practice operations and defect handling in a simulated environment that perfectly mirrors the real production line, eliminating the need for extended on-the-job training while maintaining skill acquisition effectiveness
Solution Approach 2:
The system enables trainees to perform preliminary training in the virtual environment before entering the actual production line. By pre-training on various operations and defect scenarios in the VR simulation, workers acquire necessary skills in advance, reducing the time needed for on-job training and minimizing disruption to actual production
2Ease of operation
If workers are trained on general operation methods, then they can operate the plant, but they cannot immediately respond to various defect situations
Solution Approach 1:
The VR training system dynamically adjusts the training scenarios based on the trainee's progress and performance. The system transitions from basic operation training to increasingly complex defect scenarios, allowing workers to develop both operational skills and adaptability to various malfunction situations in a progressive manner
Solution Approach 2:
The system changes multiple parameters simultaneously including defect types, operational conditions, and scenario complexity. This multi-parameter variation exposes trainees to diverse situations, enhancing their ability to respond to unexpected defects while maintaining operational competence
3Productivity
If the number of production plants is increased, then secondary battery production capacity increases, but the number of skilled workers becomes remarkably insufficient
Solution Approach 1:
By creating virtual copies of production plants, the system allows multiple trainees to simultaneously practice on identical production line configurations. This eliminates the bottleneck where only one trainee can be trained on the actual production line at a time, enabling parallel training across multiple virtual instances
Solution Approach 2:
The VR training system serves multiple functions: it trains new workers, provides refresher training for existing workers, and allows practice of rare defect scenarios without affecting actual production. This multi-functionality maximizes the utility of training resources and accelerates worker preparation

AI summary
Systems and methods for executing a virtual reality (VR)-based simulation for secondary battery production are disclosed. One method includes receiving a gaze direction and gaze location of a user identified from a HMD. Content associated with a secondary battery production apparatus corresponding to the received gaze direction and gaze location is displayed on an area of a display of the HMD. User behavior information indicating a motion of the user determined from at least one of the HMD or a controller associated with the HMD is obtained. The content associated with the secondary battery production apparatus is executed based on the obtained user behavior information.
