Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual sensor uses a real sensor and processing module without quality maintenance mechanisms, then the system structure is simple, but the quality of input data cannot be maintained
Solution Approach 1:
The system performs preliminary actions by extracting multiple candidate devices before quality issues arise. The extraction unit identifies alternative devices in advance, and the switching unit prepares to switch if quality degradation occurs, preventing quality maintenance problems before they happen.
Solution Approach 2:
The session control apparatus acts as an intermediary between the processing module and multiple candidate devices. It manages the relationships and switching between devices, providing quality maintenance functionality without requiring the processing module itself to be complex.
2Reliability
If the system continuously monitors and switches devices to maintain data quality, then the quality of input data is maintained, but the system complexity increases
Solution Approach 1:
The system implements self-service by having the extraction unit automatically identify candidate devices and the switching unit autonomously switch between devices based on quality conditions. This automated self-management maintains data quality without requiring complex external control mechanisms.
3Reliability
If multiple candidate devices are extracted and switched to maintain quality, then the quality of input data is maintained, but the device management complexity increases
Solution Approach 1:
The system uses feedback mechanisms where the quality of input data from devices is continuously monitored, and this feedback information drives the switching decisions. The extraction unit and switching unit respond to quality feedback by selecting appropriate candidate devices, maintaining quality automatically.

AI summary
A session control apparatus, a session control method, and a session control program may maintain a quality of input data output to a processing module. The processing module has a defined condition regarding a quality of the input data. The session control apparatus includes an extraction unit, a selection unit, and a switching unit. The extraction unit extracts a plurality of candidates of devices. The selection unit selects at least one device from the plurality of candidates of devices. The switching unit switches the device that outputs the input data to the processing module to the at least one device selected by the selection unit. Each of the plurality of candidates of devices outputs input data satisfying the condition.
