Engineering Contradiction Analysis
1Productivity
If a sensor is integrated into a portable electronic device for real-time air quality monitoring, then the monitoring capability and data transmission are improved, but the device complexity and power management requirements increase
Solution Approach 1:
The sensing device is divided into distinct functional modules: sensor module for detection, microprocessor module for data processing, power controller module for power management, and data transceiver module for communication. Each module performs a specific function, allowing the system to achieve real-time monitoring capability while maintaining manageable complexity through modular design.
Solution Approach 2:
The modular sensing device is designed to be universally applicable in portable electronic devices for air quality monitoring. The integrated modules work together to provide comprehensive functionality including sensing, processing, power management, and data transmission, making the device suitable for various portable applications without requiring separate specialized components.
2Ease of operation
If the sensing device is equipped with its own power source, then the device can operate independently, but the installation space and device size increase
Solution Approach 1:
The power source function is extracted from the sensing device itself and provided externally through the power supply device. The power controller module in the sensing device manages power reception and distribution without requiring an internal power source, thereby reducing the installation space while maintaining independent operation capability through external power connection.
Solution Approach 2:
The power controller module acts as an intermediary between the external power supply device and the internal components (sensor, microprocessor, data transceiver). It receives power from the external source and distributes it to various components, enabling the sensing device to operate independently in terms of power management while avoiding the need for an internal power source that would increase device volume.
3Measurement precision
If the monitored data is transmitted to a cloud database for data integration, then the data accuracy and notification mechanism are improved, but the energy consumption and communication requirements increase
Solution Approach 1:
The microprocessor processes monitored data into output data before transmission to the cloud database. This preliminary processing ensures data accuracy and readiness for cloud integration, reducing the need for repeated transmissions and associated energy consumption. The data is prepared in advance for efficient cloud database reception and processing.
Solution Approach 2:
The system establishes a feedback mechanism where the cloud database receives processed output data, performs data integration and analysis, and can send control commands back to the sensing device through the data transceiver. This feedback loop improves measurement precision by enabling remote calibration and maintenance while optimizing energy consumption through intelligent data management and selective transmission based on cloud analysis.

AI summary
A driving and information transmitting system for a sensing module includes a sensing device, a power supply device and a connection device. The sensing device includes a sensor, a microprocessor, a power controller and a data transceiver. The power supply device transfers an energy to the power controller, thereby enabling the sensor. After a monitored data sensed by the at least one sensor is transmitted to the microprocessor, the monitored data is processed into an output data by the microprocessor. After the output data is received by the data transceiver, the output data is transmitted from the data transceiver to the connection device. After a control command from the connection device is received by the data transceiver, the control command is transmitted to the microprocessor to control the sensor.
