Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If workers are trained in a general method of operating a factory, then basic operational skills are improved, but the ability to respond to troubleshooting situations remains insufficient

Engineering Contradiction:
Improvebasic operational skillsVSAvoidtroubleshooting response ability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system pre-prepares multiple troubleshooting scenarios and presents them to workers before actual factory operations. Workers practice handling various abnormal situations in advance through the simulation system, which provides guided troubleshooting processes and immediate feedback, thereby improving their ability to respond to real-world problems when they occur.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If more skilled workers are trained to meet production demand, then productivity is improved, but training time and resources are consumed

Engineering Contradiction:
Improveproduction capacityVSAvoidtraining time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system creates a virtual copy of the factory environment and equipment, allowing workers to practice operations and troubleshooting without consuming actual production time. The simulation replicates real factory scenarios including normal operations and abnormal situations, enabling efficient skill development that directly transfers to the real factory setting.

Inventive Principle:
Principle #26Copying

3Ease of operation

If workers are trained through observation of experienced workers, then skill transfer is improved, but training efficiency decreases due to busy production schedules

Engineering Contradiction:
Improveskill transfer qualityVSAvoidtraining efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system replaces the mechanical process of observational learning with an automated simulation system that provides structured training scenarios, step-by-step guidance, and immediate feedback. This substitution allows workers to learn at their own pace without disrupting production schedules, while the system automatically manages multiple trainees simultaneously.

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