Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators manually monitor environmental conditions during offshore wind turbine maintenance, then they can detect hazards, but they may miss critical dangers due to distraction or delayed reaction
Solution Approach 1:
The patent introduces wearable electronic devices as an intermediary between the environment and the operator. These devices include sensors that detect environmental conditions (wind speed, wave height, temperature, etc.) and AR displays that present this information to the operator. This intermediary system ensures continuous monitoring without requiring operator attention, solving the contradiction between manual monitoring reliability and information loss.
Solution Approach 2:
The patent replaces manual visual monitoring with automated sensor-based detection systems. Environmental parameters are continuously measured by sensors integrated into the wearable device, and critical information is automatically presented through AR displays. This substitution eliminates human reaction delays and distraction issues while maintaining situational awareness.
2Productivity
If operators focus on maintenance operations, then productivity is maintained, but safety awareness of environmental hazards may be compromised
Solution Approach 1:
The patent segments the safety monitoring function from the maintenance operation function. The wearable device independently handles environmental monitoring and hazard detection, allowing operators to focus on maintenance tasks. Safety information is delivered through AR displays that present only critical alerts, ensuring both productivity and safety reliability are maintained simultaneously.
3Reliability
If comprehensive environmental monitoring is implemented across the entire work field, then all hazards are detected, but system complexity and cost increase
Solution Approach 1:
The patent implements monitoring at the local level by placing sensors and AR displays directly on the operator. Instead of deploying a comprehensive field-wide monitoring network, the system focuses on providing personalized environmental information to each operator based on their specific location and task. This local quality approach achieves hazard detection completeness while minimizing system complexity.
