Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temperature sensor is used to monitor the joining agent temperature, then temperature control is enabled, but measurement accuracy deteriorates due to sensor contamination
Solution Approach 1:
A shielding device is introduced as an intermediary between the sensor and the contamination source (joining agent). The shielding device includes a barrier fluid outlet that dispenses a protective fluid barrier, preventing contamination from reaching the sensor while allowing temperature measurement to continue accurately
Solution Approach 2:
The sensor is extracted from the direct contact zone with the joining agent by positioning it upstream of the coating material, and the shielding device extracts the harmful contamination factor by creating a protective barrier that separates the sensor from the contaminating environment
2Measurement precision
If the sensor is positioned close to the joining agent for accurate measurement, then measurement precision improves, but sensor contamination increases
Solution Approach 1:
The shielding device acts as a mediator that enables close positioning of the sensor to the joining agent while preventing contamination. The barrier fluid creates an intermediate protective layer that allows accurate measurement without direct exposure to harmful contaminants
Solution Approach 2:
The shielding device is activated before contamination can occur, creating a protective barrier in advance. The barrier fluid outlet dispenses protective fluid that preemptively shields the sensor from contamination while enabling immediate accurate measurement
