Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing patient healthcare devices lack efficient and secure methods for remote provisioning, configuration, and modification of APIs, particularly in environments where device location and user context are dynamic, such as healthcare settings.
Innovation Solution
A system utilizing a gateway device with NFC capabilities that operates as different 'state machines' based on location, time, and NFC data to manage API provisioning and updates, allowing for secure and context-aware management of patient and caregiver interactions, enabling unique user interfaces and access levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gateway device operates as different state machines based on location, time, and NFC data to manage API provisioning, then security and context-aware management are improved, but device complexity increases
Solution Approach 1:
The gateway device is divided into multiple state machines (patient state machine, caregiver state machine, administrator state machine), each handling specific user roles and contexts. This segmentation allows the system to provide role-specific functionality and security rules without requiring a single complex monolithic structure, resolving the contradiction by organizing complexity into manageable, specialized segments.
Solution Approach 2:
The gateway device dynamically transitions between different state machines based on real-time inputs including NFC data, location information, and time. This dynamic behavior allows the system to adapt its security profile and functionality according to the current context, improving security through context-aware access control while managing complexity through event-driven state transitions rather than static complex logic.
2Ease of operation
If NFC data is read and processed to determine user context and location, then ease of operation is improved, but loss of information increases due to dynamic environment factors
Solution Approach 1:
The system performs preliminary actions by reading and processing NFC data early in the interaction flow, before the user needs to access healthcare functionality. This preliminary processing establishes the user's identity, role, and contextual information in advance, allowing the gateway to pre-determine the appropriate state machine and security profile. This prevents information loss by ensuring all necessary contextual data is captured and processed before it becomes relevant for authentication and access control.

AI summary
Technologies for management of patient healthcare include a gateway device to read near field communication data from a near field communication device, determine a user associated with the near field communication device based on the near field communication data, receive sensor data from one or more sensors communicatively coupled to the gateway device and associated with a patient in response to a determination that the user is the patient, and store the received sensor data to a data storage of the gateway device.
