Dynamic Announcement Timing for Implantable Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Implantable medical devices, lacking a physical user interface, face challenges in establishing wireless communication connections due to the absence of a tactile interface for initiating announcement or advertising modes, which are typically required for creating communication links with external devices.
Innovation Solution
Incorporating a wireless communication interface with an announcement timing control module that dynamically adjusts the frequency of announcement signals based on detected environmental and operational factors, such as heart activity and battery charge level, to facilitate connection establishment without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If implantable medical devices use traditional announcement modes requiring user interface input, then connection establishment can be initiated, but the device cannot be accessed without physical interaction
Solution Approach 1:
The device automatically initiates announcement modes and establishes wireless communication connections without requiring physical user interface input. The system monitors environmental conditions and autonomously determines when to transmit announcement signals, enabling external devices to connect and communicate with the implantable medical device without physical access or manual activation.
Solution Approach 2:
The device pre-configures announcement parameters and maintains readiness to initiate connections. When environmental conditions are favorable (such as presence of external devices within range), the system proactively transmits announcement signals before explicit user commands would be possible, ensuring connection establishment is always available.
2Loss of time
If the device continuously transmits announcement signals to facilitate connection, then connection time is reduced, but power consumption increases
Solution Approach 1:
The announcement transmission frequency is dynamically adjusted based on real-time environmental monitoring. The system increases transmission frequency when external devices are detected within communication range, reducing connection time. When no external devices are present, the system reduces or suspends transmissions to conserve battery power, creating an adaptive balance between connection speed and energy consumption.
Solution Approach 2:
Instead of continuous transmission, the system uses periodic announcement signals with variable intervals. The transmission schedule adapts based on environmental conditions, using shorter intervals when connections are needed and longer intervals or idle periods when power conservation is prioritized, optimizing the trade-off between connection availability and energy usage.
