Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If measurement data are transmitted wirelessly in real-time, then remote monitoring capability is improved, but data loss occurs due to communication instability
Solution Approach 1:
The sensor amplifier stores measurement data in its internal memory before transmission to the main body unit. This preliminary storage ensures that even if wireless transmission fails or data are lost during communication, the original data remain preserved and can be transmitted later, thereby maintaining data completeness while enabling remote monitoring.
Solution Approach 2:
The sensor amplifier acts as an intermediary device between the sensor and the main body unit. It receives measurement data from the sensor, stores it temporarily in its memory, and then transmits it to the main body unit via wireless communication. This intermediary role allows the system to maintain remote monitoring capability while protecting against data loss during transmission.
2Productivity
If measurement data are continuously transmitted wirelessly, then real-time data availability is improved, but power consumption increases
Solution Approach 1:
Instead of continuously transmitting data, the sensor amplifier accumulates measurement data in its memory and transmits them periodically or in batches to the main body unit. This periodic transmission approach maintains real-time data availability while significantly reducing the frequency of wireless communication operations, thereby lowering power consumption and extending battery life.
3Device complexity
If multiple measurement devices operate independently, then device simplicity is improved, but synchronization between devices deteriorates
Solution Approach 1:
The main body unit serves as a central coordinator that receives data from multiple sensor amplifiers and provides feedback control signals back to them. This feedback mechanism enables the independently operating devices to synchronize their measurements by receiving timing instructions from the central unit, thereby maintaining both device simplicity and measurement synchronization.
4Device complexity
If all data processing is performed at the main body unit, then device complexity at sensor level is reduced, but communication load and power consumption increase
Solution Approach 1:
The data processing function is segmented and distributed between the sensor amplifier and the main body unit. The sensor amplifier performs preliminary processing such as analog-to-digital conversion and basic signal conditioning, while the main body unit handles more complex analysis. This segmentation reduces the communication load by transmitting only processed data rather than raw signals, thereby reducing power consumption while maintaining simple sensor-level devices.
