Wearable Defibrillator Alerts for Resolved System Issues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable cardioverter defibrillators (WCDs) provide excessive and disruptive feedback to users, which can be distracting and unassuring, particularly when system issues are resolved or functioning properly.
Innovation Solution
The WCD system incorporates adjustable LED illumination patterns, display brightness control, and customizable alerts to optimize user feedback, ensuring discreet and confident operation by providing positive feedback on system status and issue resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the WCD system provides continuous feedback to users about system status, then users are kept informed about system operation, but users experience excessive and disruptive feedback that is distracting and unassuring
Solution Approach 1:
The patent applies local quality by differentiating feedback delivery based on the specific system state. Different feedback modalities are used for different conditions: subtle haptic feedback for normal operation, visual feedback through LEDs for system events, and auditory feedback only when necessary. This localized approach ensures information is provided without creating excessive disruption, as each feedback type is applied only where and when it is most appropriate for the specific system state.
Solution Approach 2:
The patent implements dynamics by making the feedback system adaptive and configurable. Users can adjust feedback sensitivity and enable/disable specific feedback types through programming interfaces. The system dynamically adjusts feedback delivery based on user preferences and current operational context, transforming a static feedback mechanism into a flexible, user-adapted system that reduces unnecessary disruption while maintaining essential information delivery.
2Loss of information
If the WCD system provides detailed feedback about system issues and resolutions, then users are kept informed about system status, but users experience unnecessary distractions that reduce confidence
Solution Approach 1:
The patent applies partial action by providing feedback selectively rather than continuously. The system determines whether feedback is necessary based on the significance of the system event. Minor issues may receive subdued feedback, while critical issues receive more prominent attention. This partial feedback approach avoids information overload and unnecessary distractions, allowing users to maintain confidence by receiving only the essential information needed for system monitoring without being overwhelmed by excessive details.
3Loss of information
If the WCD system uses multiple feedback modalities (LED, display, audio, vibration), then comprehensive system status is communicated, but the feedback becomes excessive and disruptive
Solution Approach 1:
The patent applies segmentation by dividing the feedback system into distinct, independent modalities (haptic vibration, visual LED, visual display, auditory output). Each modality can be independently controlled and configured. This segmentation allows the system to activate only the necessary feedback channels for each specific system event, providing comprehensive status communication while avoiding the disruption that would result from activating all modalities simultaneously for every event.
Solution Approach 2:
The patent implements multi-functionality by designing a unified feedback control system that manages multiple feedback modalities through a single configurable interface. The programming interface allows users to configure feedback behavior that applies across all modalities consistently, while the system intelligently selects which modalities to activate based on the event type and user preferences. This universal control mechanism ensures comprehensive status communication without the chaos of uncoordinated multi-modal feedback.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The optimized feedback mechanisms enhance user confidence in the WCD's operation by clearly communicating system status and issue resolution without unnecessary distractions, promoting a more reliable and user-friendly experience.
Implementation Method 1
The one or more LEDs may include at least two LEDs and the processor may illuminate the two or more LEDs in a sequential, syncing pattern
Implementation Method 2
The alert may include one of emitting a tone, changing display content, illuminating at least one LED, emitting a vibration pattern

AI summary
In one embodiment, a method to alert a user of a wearable cardioverter defibrillator (WCD) is described. The method includes determining when a system issue is resolved and issuing an alert when the system issue is resolved. In some embodiments, the method may detect the system issue and issuing a system alert based at least in part on the system issue. The method may then monitor a status of the system issue. In some instances, the method may detect an abnormality in system operation sand determine a severity rating for the abnormality. The method may determine if the abnormality satisfies a time duration threshold based at least in part on the severity rating.
