Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single temperature sensor is used to reduce cost, then device complexity and cost are reduced, but measurement precision and reliability of temperature decay detection deteriorate
Solution Approach 1:
The single temperature sensor is functionally segmented into multiple detection zones through the auxiliary aperture system. The auxiliary aperture directs water flow to specific locations around the sensor, creating virtual multiple sensing points that monitor different regions of the tank independently, thereby maintaining measurement precision while using only one physical sensor.
Solution Approach 2:
The auxiliary aperture acts as an intermediary element that redirects water flow to enhance temperature sensor detection capability. By positioning the auxiliary aperture to direct cool water flow across the sensor location, it mediates between the single sensor limitation and the need for accurate temperature decay monitoring across different tank zones.
2Device complexity
If temperature sensors are positioned to monitor general tank temperature, then device complexity is minimized, but detection of flow events and temperature decay accuracy deteriorates
Solution Approach 1:
The auxiliary aperture is pre-configured to redirect water flow to specific locations around the temperature sensor before measurement occurs. This preliminary action of directing cool water across the sensor ensures that when flow events occur, the sensor is positioned to capture temperature changes at the most informative location, enhancing flow event detection without adding complexity.
Solution Approach 2:
The temperature monitoring system applies local quality by concentrating detection effort at strategically selected locations. The auxiliary aperture directs water flow to create localized temperature variations around the sensor, allowing the single sensor to detect flow events and temperature decay with high accuracy by monitoring specific critical zones rather than attempting uniform whole-tank monitoring.
