Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the sensing part and processing part are releasably connected to allow replacement of worn sensing parts, then the costly electronics can be reused, but the sensing part needs to be recalibrated each time when connected to another processing part and historical data is lost
Solution Approach 1:
The identification means in the sensing part and identification recognition means in the processing part establish the connection and retrieve calibration data before the sensing part is actually used for measurement. This preliminary recognition action ensures that calibration parameters are transferred automatically when the sensing part is coupled to the processing part, eliminating the need for manual recalibration and preventing loss of historical data.
2Ease of repair
If the sensing part and processing part are releasably connected to allow replacement of worn sensing parts, then the costly electronics can be reused, but the sensing part needs to be recalibrated each time when connected to another processing part
Solution Approach 1:
The system performs automatic calibration data retrieval and transfer through the identification means and recognition means. When a sensing part is coupled to a processing part, the processing part automatically recognizes the sensing part's identification, retrieves the corresponding calibration parameters from stored data, and configures itself without requiring manual recalibration operations by the user.
3Adaptability or versatility
If sensors are designed with integrated electronics in the sensor itself for field work, then the sensor does not require a separate analyzer, but the entire sensor including costly electronics must be replaced when worn
Solution Approach 1:
The sensor system is divided into two separable parts: a sensing part that contains the electrode and identification means, and a processing part that contains the electronics including data processing unit, memory, power supply, and communication interface. This segmentation allows the durable processing part to be reused while only the worn sensing part needs replacement, combining field work capability with cost-effective maintenance.
4Reliability
If the processing part is dedicated to a specific sensing part with calibration parameters stored in memory, then the sensor functionality is optimized, but the sensing part cannot be exchanged with another sensing part without recalibration
Solution Approach 1:
The processing part is designed with universal capability to work with different sensing parts through the identification means system. The processing part can recognize multiple sensing parts, retrieve their specific calibration parameters from stored data, and automatically configure itself for each sensing part type, thus maintaining optimized functionality while enabling exchangeability between different sensing parts.
