Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wired environmental sensors transmit data directly to remote servers, then data transmission is achieved, but transmission efficiency is poor and bandwidth is wasted in remote areas
Solution Approach 1:
The patent introduces a gateway device as an intermediary between wired environmental sensors and remote servers. The gateway collects data from multiple sensors, performs local processing and filtering, then transmits only essential processed data to remote servers via NB-IoT wireless communication. This mediator approach reduces unnecessary data transmission and optimizes bandwidth usage in remote areas.
Solution Approach 2:
The system segments the data transmission process into two stages: local data collection and processing at the gateway, then selective transmission to remote servers. This segmentation allows preprocessing of sensor data locally, filtering out redundant information before wireless transmission, thereby improving transmission efficiency and reducing bandwidth consumption.
2Adaptability or versatility
If multiple sensor protocols are supported, then versatility is improved, but device complexity increases
Solution Approach 1:
The gateway device is designed with universal multi-functionality to support multiple sensor communication protocols (RS232, RS485, SDI-12, Modbus, BACnet) and multiple wireless transmission methods (NB-IoT, LTE, Wi-Fi, Ethernet). This universal design allows a single device to handle diverse sensor types and communication requirements without requiring separate specialized devices for each protocol.

AI summary
Various arrangements involving environmental sensor gateways are presented. Wire terminals of the environmental sensor gateway may be connected with wires that are electrically connected with environmental sensors. Multiple communication interface protocols used by the environmental sensors connected via the wires may be determined. One or more operator-specific applications may be executed. Each operator-specific application may be mapped to a corresponding environmental sensor. Environmental sensor measurements may be received from the environmental sensors via the wire terminals. Based on a wire terminal through which an environmental sensor measurement is received, the environmental sensor measurement may be processed using an operator-specific application. The environmental sensor measurement may be processed using the operator-specific application.
