Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the electrode sensor is integrally configured by burying the pair of applying electrodes into the sensor main body, then the structure is simplified and manufacturing is easier, but cleaning becomes difficult and requires replacement of the entire sensor
Solution Approach 1:
The electrode sensor is divided into separate components: the sensor main body and the applying electrodes. The applying electrodes are no longer buried within the sensor main body but are positioned externally, allowing them to be cleaned or replaced independently without affecting the sensor main body structure.
2Ease of manufacture
If the electrode sensor is integrally configured, then manufacturing cost is reduced, but replacement of electrodes requires replacing the entire sensor increasing cost
Solution Approach 1:
By separating the applying electrodes from the sensor main body, the system allows selective replacement of only the electrodes when needed, rather than replacing the entire sensor assembly. This reduces costs and enables adaptation to different measurement requirements.
Solution Approach 2:
The applying electrodes are made replaceable and interchangeable, allowing the system to adapt to different measurement conditions by swapping electrodes with different properties (e.g., different materials, surface treatments) while keeping the sensor main body.
3Adaptability or versatility
If the applying electrodes are made replaceable, then cleaning and adaptation to different liquid samples becomes easier, but device complexity increases
Solution Approach 1:
The applying electrodes are separated from the sensor main body and can be independently replaced. This segmentation enables easy adaptation to different liquid samples by swapping electrodes with appropriate surface treatments or materials without complicating the overall device structure.
