Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement methods with multiple sensors and repeated measurements are used, then measurement precision can be improved, but measurement time and productivity deteriorate significantly
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated robotic system. The robot arm mechanically positions sensors and acoustic cameras to multiple locations without human intervention, while software algorithms automatically process measurements to identify vibration and noise sources. This substitution of manual operations with automated systems resolves the contradiction by maintaining measurement precision through systematic multi-position data collection while dramatically improving productivity through automation.
Solution Approach 2:
The system performs preliminary actions by pre-programming measurement locations and paths on the robot arm before actual measurements begin. The software pre-calculates optimal sensor positions and acoustic camera angles, allowing the system to efficiently execute measurements without real-time manual planning. This preliminary preparation enables rapid automated measurements while ensuring comprehensive data collection for accurate source identification.
2Productivity
If automated robotic measurement systems are used, then productivity and measurement speed are improved, but device complexity increases
Solution Approach 1:
The robotic measurement system is designed with multi-functionality to handle both vibration sensor measurements and acoustic camera measurements using the same robot arm and control software. The system can switch between different measurement tasks and sensor types without requiring separate dedicated systems. This universality reduces device complexity by consolidating multiple measurement functions into a single integrated platform while maintaining high productivity through automation.
3Measurement precision
If comprehensive vibration and acoustic measurements are taken at multiple positions, then measurement precision and source identification accuracy are improved, but loss of time increases due to repeated manual measurements
Solution Approach 1:
The automated robotic system performs continuous measurements across multiple positions without interruption or manual reconfiguration. The robot arm continuously moves sensors and acoustic cameras through pre-programmed paths, collecting vibration and acoustic data at all required locations in a single uninterrupted sequence. This continuous operation eliminates the time losses associated with manual setup and repositioning while maintaining comprehensive data collection for accurate source localization.
Solution Approach 2:
The system replaces manual measurement repetition with automated robotic repetition. Instead of manually moving sensors and repeating measurements over multiple days, the robot arm automatically positions and measures at all required locations in one continuous operation. The software automatically processes the comprehensive dataset from all positions to identify vibration and noise sources, resolving the time loss issue while maintaining the precision benefits of multi-position measurements.
