Patient Interface 3D Scan Data Collection with Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data collection methods for patient interface device selection and customization often compromise patient privacy, as 3D scans containing personal information are transmitted to different parties for analysis, leading to potential leaks and discomfort due to improper fitting.
Innovation Solution
A 3D data collection method with privacy protection involves obtaining a 3D scan locally, receiving an avatar template and control point registration data from an external site, identifying and adjusting control points on the scan, and transmitting an adjusted, unrecognizable avatar template back to the external site for device selection or customization, ensuring privacy and proprietary information protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D scan data is transmitted to external parties for analysis, then device selection and customization accuracy is improved, but patient privacy and data security deteriorate
Solution Approach 1:
The patent extracts only the essential geometric features and measurements from the 3D scan data, separating them from the full detailed scan. This allows external parties to receive sufficient information for accurate device selection while the complete private data remains securely stored locally on the patient's device
Solution Approach 2:
The patent divides the data processing into segments: local processing of full 3D scans for privacy preservation, and selective transmission of extracted feature data for external analysis. This segmentation enables both privacy protection and accurate device customization
2Reliability
If full 3D scan data is stored locally, then patient privacy is protected, but device customization accuracy may deteriorate
Solution Approach 1:
The patent introduces an intermediary process that extracts essential geometric features from the local 3D scan data. This intermediary step creates a simplified representation that maintains customization accuracy while enabling secure external collaboration without exposing full private data
3Manufacturing precision
If detailed 3D scan data is shared externally, then device fitting accuracy is improved, but patient comfort and trust deteriorate
Solution Approach 1:
The patent extracts only the necessary geometric measurements and features required for accurate device fitting, leaving the detailed personal identifiable information stored locally. This extraction approach enables precise customization while maintaining patient comfort and trust through privacy preservation

AI summary
A 3D data collection method with privacy protection includes obtaining a 3D scan of at least a portion of a patient, receiving an avatar template and control point registration data, identifying control points on the 3D scan based on the control point registration data, adjusting the avatar template to coincide control points on the avatar template with control points on the 3D scan, and transmitting the adjusted avatar template.
