Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional infusion systems are used, then basic infusion functionality is provided, but precision and flexibility of infusion therapy is limited
Solution Approach 1:
The system is divided into separate functional modules: an infusion device for fluid delivery, a two-way communication device for data exchange, and a server system for remote monitoring and control. This segmentation allows each component to be optimized independently while maintaining overall system precision without excessive complexity.
Solution Approach 2:
The infusion device incorporates multiple functions including programmable infusion rates, time sequences, basal rate delivery, bolus administration, and integrated communication capabilities. This multi-functionality achieves precise and flexible infusion therapy while reducing the need for multiple separate devices.
2Loss of information
If remote monitoring and control capabilities are added, then clinician oversight and payer monitoring are improved, but device complexity increases
Solution Approach 1:
A two-way communication device serves as an intermediary between the infusion device and the server system. This intermediary handles all data exchange, allowing the infusion device to maintain relatively simple architecture while still enabling comprehensive remote monitoring and control through the communication bridge.
Solution Approach 2:
The system implements bidirectional communication with feedback loops where the infusion device sends operational data to the server, and the server sends control instructions back to the infusion device. This feedback mechanism enables real-time monitoring and adjustment without requiring complex embedded intelligence in the infusion device itself.
3Adaptability or versatility
If programmable rates and time sequences are implemented, then infusion flexibility is improved, but device complexity increases
Solution Approach 1:
The controller is pre-programmed with infusion rates, time sequences, basal rates, and bolus parameters before operation. This preliminary configuration allows the system to execute complex infusion regimens with simple operational input, achieving high flexibility without requiring complex real-time decision-making logic during operation.

AI summary
A system for infusing liquid to a body includes an infusion device, a network interface with a cell phone and wireless link and a network server system capable of communication with the infusion device through the network interface. The server system has access to a file of information specific to the controller for the infusion device. The infusion device includes a source of infusion fluid, a delivery port, a pump between the source of infusion fluid and the delivery port and a controller capable of programmable pump rate and sequence. A method for infusing liquid to a body includes controlling infusion using a programmable controller, establishing a file of information specific to the controller accessible to an extended area network server system and remotely transmitting commands to the controller. The information specific to the controller in the file is amended from a control terminal remote from the body. Operating instructions responsive to the updated information in the file are provided over an extended area network to a programmable two-way communication device. The device is capable of communication with the controller to forward operating commands. Requests for a bolus or a basal rate change are made through input to the two-way communication device which responds with commands transmitted over the wireless link to the controller consistent with the operating instructions from the server system. Network access through a monitoring terminal to the incidents of amending information specific to the controller is used for generating payments for the incidents of amending information specific to the controller accessed by the monitoring terminal.
