Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable calibration apparatus is used for field calibration, then mobility and ease of operation are improved, but measurement precision and calibration accuracy deteriorate
Solution Approach 1:
The calibration apparatus integrates multiple calibration functions (voltage, current, resistance, frequency, temperature, pressure, flow, level, pH, dissolved oxygen, conductivity, TDS, salinity, ORP measurement, and simulation) into a single portable device. This multi-functionality allows the apparatus to maintain high measurement precision across various calibration tasks while preserving mobility, eliminating the need for multiple specialized instruments in the field.
2Adaptability or versatility
If multiple I/O channels are integrated into the portable apparatus, then functionality and versatility are improved, but device complexity increases
Solution Approach 1:
The portable calibration apparatus incorporates multiple independent input/output channels that can be individually configured and controlled. Each channel is segmented to handle specific measurement or simulation functions, allowing the system to manage complexity through modular design while maintaining high versatility. The channels can be independently activated based on calibration needs, reducing operational complexity despite the multi-functional capability.
3Productivity
If advanced calibration features like synchronized command execution and data storage are added, then calibration capability and productivity are improved, but ease of operation deteriorates
Solution Approach 1:
The calibration apparatus incorporates automatic configuration and execution capabilities that reduce manual intervention. The system can automatically configure calibration procedures, execute synchronized commands across multiple channels, and store calibration data without requiring complex manual setup by the user. This self-service functionality maintains advanced calibration capabilities while simplifying the user interface and ease of operation.
