Innovation Solution
A medical device control system utilizing Bluetooth Low Energy (BLE) modules, radio transmitter modules in the form of badges worn by staff, and a control device that detects and verifies identification features via signal strength and optional password entry to quickly authorize operators, enabling simplified and secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex registration procedure is implemented for authorizing operators, then security and authorization control are improved, but the time required for registration and system accessibility deteriorate in emergency situations
Solution Approach 1:
The system performs preliminary actions by storing identification features of authorized personnel in advance in the control device. During emergency situations, the system only needs to detect and match these pre-stored identification features rather than performing a full registration procedure, thus maintaining security while enabling rapid access.
Solution Approach 2:
The invention extracts the essential authorization element (identification feature) from the complex registration procedure. Instead of requiring full credential verification, the system isolates and uses only the critical identification feature for quick authentication, reducing registration time while maintaining authorization control.
2Adaptability or versatility
If traditional control panels or remote controls are used for medical devices, then device control functionality is maintained, but system complexity and the number of physical control devices increase
Solution Approach 1:
The mobile computing device serves multiple functions: it acts as both the control interface for medical devices and the authorization medium through its identification feature. This universal approach eliminates the need for separate remote controls or control panels, reducing the number of physical devices while maintaining control functionality.
Solution Approach 2:
The system introduces a wireless communication intermediary that enables the mobile computing device to communicate with the control device without requiring physical control panels or remote controls. This intermediary layer allows versatile control access while minimizing the number of physical control devices needed.
3Speed
If immediate operation of medical devices is enabled in emergency situations, then operational speed and responsiveness are improved, but security and authorization verification may be compromised
Solution Approach 1:
The system performs preliminary authorization setup by storing identification features of authorized personnel in advance. During emergencies, this pre-configured data enables rapid verification that maintains both speed and security, as the system only needs to detect and match the identification feature against pre-stored authorized identifiers.
Solution Approach 2:
The invention applies partial action by using only the essential identification feature for authorization verification in emergency situations, rather than performing complete multi-factor authentication. This partial verification approach maintains adequate security while enabling rapid operational responsiveness.
