Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used to transmit syringe pump operation data, then the device complexity is reduced and ease of operation is improved, but data security is compromised due to potential hacking and unauthorized access
Solution Approach 1:
A radio frequency (RF) identification tag is introduced as an intermediary carrier to store and transmit syringe pump operation data. The RFID tag acts as a secure intermediary between the syringe pump and external devices, enabling wireless data access while maintaining security through controlled authentication mechanisms. This resolves the contradiction by allowing ease of wireless operation while preventing unauthorized access through the intermediary's security features.
2Ease of operation
If an app is used to control the syringe pump, then ease of operation is improved, but device complexity increases due to additional control components and software integration
Solution Approach 1:
The control functionality is extracted from the syringe pump itself and relocated to an external mobile device application. The syringe pump retains only essential execution functions, while the app handles user interface, parameter setting, and control logic. This extraction reduces the complexity of the syringe pump's control system while maintaining ease of operation through the mobile app interface.
3Measurement precision
If real-time monitoring of syringe pump data is implemented, then measurement precision is improved, but loss of time increases due to continuous data processing and transmission
Solution Approach 1:
Instead of continuously transmitting raw data streams, the system creates periodic snapshots or summaries of syringe pump operation data and stores them on RFID tags. Mobile devices can then copy and analyze these data copies as needed, achieving real-time monitoring capability without the continuous time loss associated with constant data transmission and processing. The copying approach allows on-demand data retrieval and analysis.

AI summary
A radio frequency operation data control method, an apparatus, and a syringe pump are disclosed. The method includes: when a radio frequency operation task is triggered, controlling a syringe pump to open at least one perfusion channel to perform perfusion operation; in a dual control mode, when the temperature values of multiple sites of a radio frequency operation object exceed a temperature protection range, controlling the syringe pump to open or close some or all of the perfusion channels, and / or to adjust the flow rates of some or all of the perfusion channels; when the flow rates reach a temperature-control limit, if the temperature values still exceed the temperature protection range, adjusting the radio frequency output power; and when the impedance values of multiple sites exceed a preset impedance protection range, controlling the syringe pump to adjust the flow rates of some or all of the perfusion channels. The present invention can improve the timeliness, accuracy and pertinence of liquid perfusion during the radio frequency operation.
