Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If measuring devices are designed to handle multiple measurement conditions, then adaptability improves, but device complexity increases
Solution Approach 1:
The measuring device is divided into separate functional modules: sensor units that generate primary signals and transmitters that process these signals. This segmentation allows each module to be independently optimized and replaced based on specific measurement requirements, improving adaptability without increasing overall system complexity.
Solution Approach 2:
The transmitter is designed as a universal processing unit that can handle primary signals from different types of sensor units through standardized interfaces. This multi-functionality allows a single transmitter to support multiple measurement conditions and sensor types, enhancing adaptability while maintaining simple sensor unit designs.
2Measurement precision
If measuring devices are highly specialized for specific conditions, then measurement precision improves, but ease of operation deteriorates
Solution Approach 1:
By separating the specialized sensing function from the general processing function, sensor units can be highly specialized for specific measurements while transmitters provide standardized processing. This allows precise measurements through specialized sensors while maintaining ease of operation through standardized transmitter interfaces.
Solution Approach 2:
Sensor units are designed to be self-contained with all necessary sensing elements and signal generation capabilities, requiring minimal configuration when replaced. The standardized interfaces enable plug-and-play operation, improving ease of replacement and calibration while maintaining measurement precision through specialized sensor design.
3Reliability
If calibration and replacement are performed frequently, then measurement reliability improves, but loss of time increases
Solution Approach 1:
The separable sensor unit and transmitter design allows sensor units to be quickly replaced without affecting the transmitter or requiring complex recalibration. This reduces downtime significantly while maintaining measurement reliability through easy replacement of potentially faulty sensor units.
Solution Approach 2:
Sensor units can be designed as disposable or easily replaceable components that are replaced rather than repaired. This approach reduces the time and complexity associated with calibration and maintenance, improving overall system availability while maintaining measurement reliability through fresh sensor units.
4Ease of manufacture
If equipment is standardized and modularized, then ease of manufacture improves, but device complexity increases
Solution Approach 1:
The system is divided into standardized sensor units and transmitters with well-defined interfaces. This segmentation enables independent manufacturing and testing of each module, simplifying production processes while the standardized interfaces reduce the overall system complexity by providing clear integration rules.
Solution Approach 2:
The transmitter is designed as a universal platform that can process signals from various sensor types through standardized interfaces. This multi-functionality reduces the need for multiple specialized transmitter models, simplifying manufacturing and inventory management while maintaining the benefits of modular design.
