Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensor designs with specific electronic connections are used, then each sensor can be precisely calibrated for its specific application, but the equipment complexity increases and sensor replacement requires recalibration by skilled technicians
Solution Approach 1:
The system divides the measurement equipment into modular sensor cartridges that can be independently replaced. Each cartridge contains a sensor and its specific electronic board, separating the sensor module from the main equipment body. This allows individual sensor replacement without affecting other components, reducing overall equipment complexity while maintaining calibration precision through module-level optimization.
Solution Approach 2:
The equipment employs a universal cartridge interface that can accommodate different sensor types through standardized mechanical and electrical connections. The central electronic board automatically recognizes and adapts to various sensor cartridges, enabling one equipment unit to perform multiple measurement functions without requiring recalibration by skilled technicians, thus reducing device complexity while maintaining precision.
2Manufacturing precision
If sensors are fixed in specific locations within the equipment, then each sensor can be optimized for its specific measurement function, but sensor replacement and maintenance become difficult and time-consuming
Solution Approach 1:
Sensors are packaged in discrete, removable cartridges that can be easily extracted and replaced. The cartridge design separates the sensor from the main equipment body, allowing field technicians to perform maintenance without complex disassembly procedures, significantly improving ease of repair while maintaining installation precision through standardized interfaces.
Solution Approach 2:
Sensors are pre-assembled and pre-calibrated in cartridge form at the factory before deployment. This preliminary preparation ensures optimal installation precision when the cartridge is installed, while also enabling quick replacement in the field without requiring on-site calibration procedures, thus improving both manufacturing precision and ease of repair.
3Adaptability or versatility
If multiple different sensor types are integrated into the equipment, then the equipment can measure various environmental parameters, but the equipment dimensions become very large
Solution Approach 1:
The equipment uses a universal cartridge interface that allows a single equipment unit to accommodate multiple different sensor types. Instead of integrating all sensors simultaneously, the system provides versatility through interchangeable cartridges, maintaining a compact equipment volume while enabling measurement of various environmental parameters through selective cartridge installation.
Solution Approach 2:
The sensor configuration is made dynamic through interchangeable cartridges rather than fixed integrations. Users can adapt the equipment to different measurement needs by swapping cartridges, providing high adaptability without requiring all sensors to be present simultaneously, thus maintaining compact equipment dimensions while supporting versatile measurement capabilities.
4Measurement precision
If sensors are recalibrated in the laboratory or using mobile laboratories, then measurement precision is maintained, but the time and cost of maintenance increases significantly
Solution Approach 1:
Sensors are pre-calibrated and pre-configured in cartridge form at the factory before deployment to the field. This preliminary calibration ensures measurement precision is established upfront, eliminating the need for time-consuming on-site recalibration procedures. When sensors need maintenance, the entire pre-calibrated cartridge is replaced as a unit, maintaining precision while minimizing calibration time and cost.
Solution Approach 2:
The system enables field technicians to perform sensor replacement and basic maintenance without requiring specialized calibration equipment or expert intervention. The standardized cartridge interface and automatic sensor recognition allow the equipment to serve itself through simple cartridge swaps, maintaining measurement precision while dramatically reducing the time and resources required for maintenance compared to traditional laboratory recalibration methods.
