Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual blocking and unblocking methods are used, then device security is maintained through basic password protection, but the process is time-consuming and prone to being bypassed in time-pressured environments
Solution Approach 1:
The system performs preliminary authentication by storing authorized mobile device identifiers in advance. When a mobile device approaches the medical device, the system automatically recognizes it and prepares for rapid unblocking without requiring manual password entry, thus resolving the contradiction between security and time efficiency.
Solution Approach 2:
The patent replaces the mechanical/manual password entry system with an automated wireless communication-based authentication system. The mobile terminal communicates wirelessly with the medical device to automatically authenticate and unlock, eliminating the need for manual keyboard input and significantly reducing the time required for blocking and unblocking operations.
2Ease of operation
If manual password entry is required for blocking and unblocking, then basic access control is implemented, but the process becomes complex and user-unfriendly in daily routine operations
Solution Approach 1:
The system enables self-service authentication where the mobile device automatically presents its stored credentials to the medical device. The authentication process occurs without user intervention in the blocking/unblocking action itself, making the process extremely simple while maintaining security through pre-configured authorized device identifiers.
Solution Approach 2:
The mobile terminal acts as an intermediary between the user and the medical device authentication system. It stores authorized identifiers and automatically communicates them to the medical device, simplifying the user interaction to merely presenting the device while maintaining robust security through the intermediary's pre-configured credentials.
3Productivity
If automated wireless authentication is implemented, then rapid and user-friendly access is achieved, but the system complexity increases with additional communication protocols and authentication mechanisms
Solution Approach 1:
The system uses universal wireless communication protocols (such as Bluetooth or NFC) that are already integrated in modern mobile devices. This allows the authentication system to leverage existing multi-functional communication capabilities of smartphones, minimizing additional hardware complexity while achieving rapid authentication and improving operational efficiency.

AI summary
Automatically blocking and/or unblocking a computer-supported medical device in a system includes the medical device and a mobile terminal. The mobile terminal comprises a first wireless communication device, and the medical device comprises a second wireless communication device. The medical device is automatically shifted from a blocked state into an unblocked state, if when the first communication device establishes a wireless connection with the second communication device and the signal strength of a signal of from the first communication device to the second communication device exceeds a first threshold. The medical device is automatically shifted from an unblocked state into a blocked state when the first communication device establishes a wireless connection with the second communication device and the signal strength of a signal from the first communication device to the second communication device falls below a second threshold and/or the wireless connection is interrupted for longer than a predetermined time interval.
