Problem
Conventional external infusion pumps face concerns regarding the security and accuracy of wireless communications, as they are susceptible to interception and manipulation, potentially leading to harmful medication delivery errors.
Innovation Solution
The system employs RFID tags with unique codes on remote controllers and infusion pumps for secure pairing, verifying device identification and ensuring accurate signal transmission by requiring proximity for information exchange, thereby confirming the authenticity and intention of medication delivery instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If radio frequency communication is used between remote controller and infusion pump, then wireless control capability is improved, but security against interception and manipulation deteriorates
Solution Approach 1:
The system performs preliminary pairing between the remote controller and infusion pump before actual medication delivery operations. During this pairing phase, the devices exchange and verify unique identification codes through RFID tags, establishing a trusted relationship in advance. This preliminary action ensures that only authenticated devices can communicate, preventing subsequent interception and manipulation attacks.
Solution Approach 2:
The patent introduces RFID tags as intermediary components that facilitate secure identification and verification between the remote controller and infusion pump. These tags store unique codes and enable close-proximity authentication, acting as a mediator that verifies device identities before allowing RF communication to proceed, thus enhancing security without compromising wireless control functionality.
2Ease of operation
If device pairing is simplified, then ease of operation is improved, but risk of incorrect pairing increases
Solution Approach 1:
The system employs visual indicators (such as LED lights or display icons) that change color or state to indicate pairing status. During the pairing process, these visual cues guide users through the steps and confirm successful pairing, making the process intuitive and reducing the risk of incorrect pairing while maintaining simplicity.
Solution Approach 2:
The patent replaces complex manual pairing procedures with automatic RFID-based identification and verification. When devices are brought into close proximity, the system automatically exchanges identification codes and establishes pairing without requiring users to manually input codes or navigate complex menus, thereby simplifying operation while ensuring accuracy through automated verification.
3Reliability
If proximity requirement is enforced for pairing, then security is improved, but device complexity increases
Solution Approach 1:
The system enables self-service pairing through automatic RFID authentication when devices are brought into close proximity. The unique identification codes are automatically exchanged and verified without requiring user intervention or complex configuration steps. This self-service mechanism enhances security through proximity enforcement while keeping the user-facing process simple and intuitive.
