Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If workers are trained through traditional on-the-job learning by watching experienced workers, then workers can learn practical skills, but training takes too much time and is difficult to scale due to busy production schedules
Solution Approach 1:
The patent creates a virtual copy of the roll press apparatus and production environment through 3D modeling and digital twin technology. This virtual replica allows workers to practice operations and defect responses without occupying actual production time, enabling skill development parallel to production activities.
Solution Approach 2:
The simulation system enables workers to perform preliminary training on defect scenarios and operational procedures before encountering actual production issues. Workers can practice responding to various defect conditions in the virtual environment, preparing them in advance for real-world situations without delaying production.
2Productivity
If more skilled workers are hired to meet production demand, then production capacity increases, but labor costs and management complexity increase
Solution Approach 1:
The simulation system enables workers to self-train on defect scenarios and operational procedures without requiring extensive instructor time. Workers can independently practice and improve their skills through the virtual environment, reducing the need for additional trained supervisors and instructors.
Solution Approach 2:
The virtual simulation system serves multiple functions: training new workers, upskilling existing workers, documenting standard procedures, and providing a platform for defect scenario practice. This multi-functionality consolidates what would otherwise require multiple separate training programs and personnel.
3Ease of operation
If general factory operation training is provided to workers, then workers understand basic procedures, but they cannot immediately respond to various defect situations that occur during factory operation
Solution Approach 1:
The simulation system provides specialized training modules for specific defect scenarios and operational situations. Rather than generic training, workers can practice responding to particular defect conditions they may encounter, developing targeted skills for specific situations while maintaining basic operational knowledge.
4Manufacturing precision
If a digital twin virtual model of the roll press is created for prediction and diagnosis, then processing quality and fault detection improve, but system complexity and computational requirements increase
Solution Approach 1:
The patent creates a virtual copy of the roll press apparatus that mirrors the physical system's geometry, materials, and processes. This digital twin enables virtual experimentation and parameter optimization without modifying the actual equipment, improving processing quality through simulation-based insights while avoiding complex hardware modifications.
