Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple state quantities are monitored to improve abnormality detection accuracy, then the reliability of abnormality detection is improved, but the device complexity increases due to multiple sensors and threshold settings
Solution Approach 1:
The patent combines multiple state quantity monitoring functions into a single integrated display device that shows all parameters (vibration, temperature, pressure, flow rate, rotational speed, current) on one screen. This merging approach maintains comprehensive monitoring capability while simplifying the overall system architecture by consolidating display and control functions.
Solution Approach 2:
The display device is designed with multi-functionality, serving as both a monitoring display and a threshold setting device. It can display multiple state quantities simultaneously and allows users to set and adjust thresholds for each parameter, eliminating the need for separate specialized devices for each function.
2Adaptability or versatility
If thresholds are customized for each user's management level and installation conditions, then the adaptability of the system is improved, but the ease of operation deteriorates due to the need for site-specific threshold setting
Solution Approach 1:
The threshold values are made dynamically adjustable by users through the display device interface. Instead of fixed predetermined thresholds, the system allows real-time modification of threshold values based on user needs and installation conditions, enabling flexible adaptation without complex reconfiguration procedures.
Solution Approach 2:
The system enables users to independently set and adjust their own threshold values directly through the display device without requiring external configuration or specialized setup procedures. This self-service capability allows end users to customize monitoring parameters according to their specific management levels and operational requirements.
3Device complexity
If traditional separate display methods are used for each state quantity, then the device complexity is reduced, but the loss of information occurs as users cannot easily correlate multiple parameters
Solution Approach 1:
The patent merges multiple separate state quantity displays into a single integrated visual interface showing all parameters simultaneously. This allows users to see vibration, temperature, pressure, flow rate, rotational speed, and current values together on one screen, preserving the simplicity of a single display device while eliminating information loss through correlated parameter visualization.
Solution Approach 2:
The system transitions from one-dimensional separate displays to a multi-dimensional integrated display that presents multiple state quantities in a unified spatial arrangement. This dimensional change allows simultaneous visualization of multiple parameters and their interrelationships without requiring multiple separate devices or complex data correlation processes.
