Wearable Defibrillator Tapping Interaction via Motion Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable defibrillator systems require precise dexterity and direct access for patient interaction, which can be challenging in stressful situations, especially for those with mobility or hearing impairments, and do not preserve patient dignity.
Innovation Solution
A wearable defibrillation system incorporating a motion sensor that allows patients to respond with simple tapping motions, eliminating the need for precise button pressing and enabling communication through vibrations or sounds, allowing for conscious feedback without direct access to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional button-based interaction is used in wearable defibrillator systems, then precise control and direct access are required, but this increases the difficulty of operation for patients in stressful situations and those with mobility impairments
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a motion sensing system that detects taps on the wearable device's housing. The motion sensor converts mechanical tap movements into electrical signals, eliminating the need for precise button manipulation while maintaining patient control over shock delivery.
Solution Approach 2:
The motion sensor acts as an intermediary between the patient's physical actions and the defibrillator's shock delivery system. Instead of requiring direct contact with buttons, the sensor mediates the interaction by detecting tap motions and translating them into control signals, thereby reducing the dexterity requirements.
2Reliability
If buttons are provided for patient interaction, then precise control is achieved, but this increases device complexity and cost while requiring direct access that may compromise patient dignity
Solution Approach 1:
The patent extracts the button mechanism from the device entirely and replaces it with a motion sensing system. The physical buttons are removed, and their control function is achieved through motion sensors that detect taps on the housing, thereby simplifying the device structure while maintaining patient control capabilities.
Solution Approach 2:
Instead of using physical buttons, the system uses motion sensors to detect and copy the intent behind button presses. The sensor captures the motion pattern of a tap and translates it into the equivalent control signal, preserving the patient's control without requiring the physical button component.
3Reliability
If the patient must directly access the device for interaction, then control is precise, but this compromises patient dignity and privacy in stressful situations
Solution Approach 1:
The patent moves the interaction interface from a direct tactile dimension (buttons requiring hand contact) to a distant motion detection dimension. The motion sensor detects taps from a distance, allowing patients to interact with the device without direct contact, thereby preserving dignity and privacy while maintaining responsiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances patient interaction in stressful situations by reducing dexterity requirements, preserving dignity, and accommodating individuals with mobility or hearing impairments, while providing a reliable means to cancel unnecessary shocks.
Implementation Method 1
The motion sensor registers the tapping, and interprets it as a reply from the patient
Implementation Method 2
The output device emits a sound or a vibration for the patient
Data Source
AI summary
A wearable defibrillation system includes an output device and a motion sensor. The output device emits a sound or a vibration for the patient, who responds by deliberately tapping the system. The motion sensor registers the tapping, and interprets it as a reply from the patient. The reply can be that the patient is conscious, or convey data that the patient enters by tapping the right number of times, or that the patient wants attention, and so on. Since the patient does not need direct access to the wearable defibrillation system for tapping it, he or she can wear it under their other garments, which helps preserve their dignity and privacy.
