Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple remote sensors are deployed for data collection, then measurement coverage and data quality are improved, but the system's ability to distinguish and process signals from individual sensors deteriorates
Solution Approach 1:
The system divides the signal transmission and identification process into segments by assigning unique identification codes to each remote sensor. The base unit receives and processes these segmented signals with their associated identification codes, enabling distinction between multiple sensors without requiring complex signal routing or manual configuration.
2Ease of operation
If remote sensors are made detachable and integratable with the main unit, then operational flexibility and ease of use are improved, but device complexity increases
Solution Approach 1:
The base unit is designed with universal functionality to operate both with and without remote sensors attached. It can process signals from wired sensors, wireless sensors, or no sensors at all, and can function as a standalone meter or as part of an expanded remote sensing system. This multi-functionality reduces the need for multiple specialized devices while maintaining operational flexibility.
3Ease of operation
If wireless transmission is used for remote sensors, then ease of deployment and mobility are improved, but power consumption increases
Solution Approach 1:
The wireless remote sensors are designed to transmit data periodically rather than continuously, and can enter low-power sleep modes between transmissions. This periodic operation reduces overall power consumption while still providing adequate monitoring coverage, allowing battery-powered sensors to operate for extended periods without replacement or recharging.

AI summary
A multisensory meter system is disclosed. The system comprises one main unit and a plurality of remote units. Each remote unit has at least a sensor to measure a physical parameter and wirelessly transmit the measured parameter as a signal to the main unit. The main unit and the remote units have an interface that allows at least one the remote units to be attached to the main unit. When attached, the main unit and the remote unit function as a single meter, and the main unit is capable of receiving signals from the other remote units. In one embodiment, the main unit and the remote units form a mesh network to transmit and receive signals, wherein each remote unit receives signals and transmits said signals. The mesh network may also contain relays. The remote units may measure a number of physical parameters such as relative humidity, temperature, vibration, moisture, electrical current, air speed, voltage and rotational speed. The signals may contain a unique identifier or code, and may be broadcast in unique frequencies.
