Innovation Solution
A sensor system that includes a first sensor device and a second sensor device, where the first sensor device transmits calibration information to the second sensor device, allowing for accurate calibration of environmental measurements, even in indoor spaces, and provides rewards for successful calibration, ensuring accurate data transmission and customer convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensors perform self-calibration in indoor settings, then calibration can be performed without external equipment, but measurement accuracy deteriorates due to difficulty of self-calibration in controlled environments
Solution Approach 1:
The patent introduces a server as an intermediary that receives calibration information from multiple sensors and distributes it to other sensors. This mediator enables indirect calibration where sensors calibrate themselves using data from other sensors rather than requiring external calibration equipment, thus maintaining ease of operation while improving measurement precision through cross-sensor validation.
Solution Approach 2:
The system implements feedback by having sensors transmit their calibration information to a server, which then uses this information to improve the calibration of other sensors. The calibration information flows back to sensors, creating a continuous improvement loop that enhances measurement accuracy over time while maintaining the self-calibration capability.
2Measurement precision
If multiple sensors transmit calibration information to a server, then calibration accuracy improves through data aggregation, but system complexity increases due to additional communication infrastructure
Solution Approach 1:
The server performs multiple functions: it receives calibration information from sensors, processes and aggregates this data, and distributes calibrated information back to sensors. It also provides reward management for calibration participation. This multi-functionality consolidates complex operations into a single centralized component, improving calibration accuracy without proportionally increasing overall system complexity.

AI summary
There is provided a sensor system including a reward transmission unit which transmits a reward for calibration by a calibration unit. The calibration unit calibrates an environmental measurement value of a measurement target that is measured by a second environmental sensor, based on first calibration information for calibrating an environmental measurement value of a measurement target that is measured by a first environmental sensor. The sensor system may further include: a first sensor device having a calibration information transmission unit which transmits the first calibration information; and a second sensor device having a receiving unit which receives the first calibration information that is transmitted by the calibration information transmission unit, and the calibration unit.
