EEG Assembly Alerting via NFC Link and External Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing EEG assembly systems face challenges in maintaining a reliable and user-friendly alerting mechanism, particularly due to power consumption issues with wireless communication and periods of downtime when operating without an external device, and the lack of a ready means for visual presentation of relevant information.
Innovation Solution
The method employs an external device with near-field magnetic communication (NFC) for establishing a wireless connection with an EEG assembly, using inductive short-range communication to transmit data messages and provide alerts, ensuring reliable and user-friendly alerting by positioning the device close to the EEG assembly and utilizing presentation means for information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wireless communication is used to transmit EEG data and alerts, then information can be presented to the user, but power consumption increases
Solution Approach 1:
The system uses periodic wireless communication only when needed (during alerts or data synchronization) rather than continuous transmission. The EEG assembly transmits data periodically to the external device, and wireless communication is activated on-demand for alert presentation, reducing overall power consumption while maintaining information delivery capability.
Solution Approach 2:
The patent separates the power-consuming wireless communication and presentation functions into an external device, while the implanted EEG assembly retains only minimal communication capabilities. This extraction of heavy power-consuming components to the external device significantly reduces the power burden on the implanted system.
2Use of energy by moving object
If the EEG assembly operates without an external device, then power consumption is reduced, but alerting reliability decreases due to periods of downtime
Solution Approach 1:
The external device acts as an intermediary that stores EEG data locally and presents alerts when the user is within range. This mediator approach allows the implanted assembly to operate in low-power mode while the external device ensures alerting reliability by buffering and presenting information when communication is possible.
Solution Approach 2:
The external device preliminarily receives and stores EEG data and alert information when available, so that alerts can be presented later when the user is within range. This preliminary action ensures that no alert information is lost due to periods when the external device is not nearby, maintaining reliability while allowing the implanted device to conserve power.
3Loss of information
If an external device is used for alert presentation, then information can be displayed visually, but device complexity increases
Solution Approach 1:
The external device is designed to perform multiple functions: it serves as a data receiver, storage unit, alert presenter, and communication interface. By making the external device multi-functional, the patent avoids adding separate dedicated components for each function, thereby managing system complexity while achieving comprehensive information presentation capability.
