AR/VR Scaffold for Wearable Medical Device Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable medical devices, such as wearable cardioverter defibrillators, face challenges in achieving a precise and comfortable fit due to one-size-fits-all designs that do not account for individual body shapes and anatomy, leading to potential discomfort, reduced wearability, and inaccurate data collection.
Innovation Solution
The implementation of a customizable scaffold or platform using augmented and virtual reality (AR/VR) technologies to assist in the fitting of wearable devices, allowing for AI-guided customization and optimal placement of electrodes and sensors based on user-specific needs and health status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one-size-fits-all or predetermined sizes are used for wearable devices, then manufacturing complexity is reduced and ease of manufacture is improved, but fitting precision and data quality deteriorate
Solution Approach 1:
The wearable device incorporates adjustable components that allow dynamic modification of the scaffold geometry to match individual body contours. The framework includes movable elements and adjustable fastening mechanisms that enable real-time customization during patient application, transforming a static one-size-fits-all design into a dynamic adaptive system.
Solution Approach 2:
The scaffold structure implements local quality variations through region-specific padding, contouring, and support elements tailored to different anatomical areas. Different portions of the wearable device have customized properties (firmness, shape, support level) matched to local body geometry requirements, allowing precise fitting while maintaining overall structural integrity.
2Reliability
If customizable fitting is implemented to improve fit precision and comfort, then data quality and patient compliance are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The wearable device is divided into modular scaffold segments that can be independently adjusted, positioned, or configured. This segmentation allows customization of individual regions without redesigning the entire device, managing complexity through modularity while achieving precise anatomical matching for reliable data collection.
Solution Approach 2:
The device includes pre-configured adjustment mechanisms, pre-positioned sensors, and pre-formed scaffold structures that are prepared in advance for easy customization during application. This preliminary preparation reduces the complexity of the fitting process by providing ready-to-use components that require minimal assembly or adjustment by the user.
3Duration of action of moving object
If extended wear period is implemented for continuous monitoring, then diagnostic reliability and prognostic accuracy are improved, but patient comfort and wear compliance deteriorate due to poor initial fit
Solution Approach 1:
The wearable device allows adjustment of multiple parameters including scaffold tension, sensor pressure, fastening force, and positioning depth to optimize comfort for extended wear. These parameter modifications enable the device to maintain both diagnostic accuracy and patient comfort over prolonged periods by fine-tuning physical characteristics to individual tolerance levels.
4Object-affected harmful factors
If physical contact during fitting is reduced to minimize contaminant transfer, then infection risk is reduced, but fitting precision and customization capability deteriorate
Solution Approach 1:
The device incorporates digital body scanning or template-based sizing systems that create virtual models of patient anatomy for fitting purposes. This copying approach allows precise measurement and customization without direct physical contact between the fitter and patient, maintaining fitting precision through digital or indirect measurement methods while eliminating contaminant transfer risks.
