Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless sensors are used, then wireless communication capability is provided, but device size becomes large and reliability decreases under high shock or vibration
Solution Approach 1:
The sensor system is divided into separate functional modules: a sensing element module and a communications module. The sensing element can be a simple pressure sensor or temperature sensor, while the communications module handles all wireless communication functions including Bluetooth and beacon protocols. This segmentation allows each module to be optimized independently, resulting in a smaller overall device size while maintaining reliability.
Solution Approach 2:
The communications module is designed to perform multiple functions: it can operate in traditional wireless sensor mode for point-to-point communication, and simultaneously function as a beacon for broadcasting data to multiple devices. This multi-functionality eliminates the need for separate beacon hardware, reducing device size while maintaining reliability through proven communication protocols.
2Duration of action of moving object
If traditional wireless communication protocols are used, then data transmission is achieved, but battery life is limited and data transmission efficiency is reduced
Solution Approach 1:
The sensor implements periodic data transmission with configurable intervals, allowing the device to enter low-power sleep modes between transmissions. The beacon functionality enables continuous data availability without requiring the radio to remain constantly active for pairing and handshaking, significantly extending battery life while maintaining data transmission efficiency through scheduled updates.
Solution Approach 2:
The system incorporates feedback mechanisms where the sensor monitors battery status, signal strength, and data freshness, then dynamically adjusts transmission intervals and power levels. This feedback-driven optimization ensures efficient battery usage while maintaining adequate data transmission rates for the application requirements.
