Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If trained experts are used to evaluate Parkinson's disease and monitor motor skills, then measurement precision is improved, but productivity is worsened due to limited frequency of assessments
Solution Approach 1:
The system enables self-monitoring of motor skills and PD symptoms through automated analysis of touchscreen gesture data. Users independently perform assessments by interacting with the touchscreen device, eliminating the need for trained experts to conduct each evaluation while maintaining measurement quality through algorithmic analysis of gesture geometry and timing patterns.
Solution Approach 2:
The patent replaces the mechanical system of expert evaluation with an automated computational system that analyzes touchscreen gesture data. Machine learning algorithms process gesture geometry, timing, and kinematic features to detect PD symptoms and monitor motor skill development, substituting human expert analysis with automated pattern recognition.
2Measurement precision
If trained experts conduct evaluations, then measurement precision is improved, but loss of time is worsened due to limited availability
Solution Approach 1:
The system enables users to conduct self-assessments at any time using touchscreen devices, eliminating waiting times for expert availability. The automated analysis immediately processes gesture data and provides feedback, allowing continuous monitoring without time loss between expert evaluations.
Solution Approach 2:
The system enables continuous assessment by analyzing touchscreen gesture data whenever users interact with the device during daily activities. This creates an ongoing monitoring process rather than discrete periodic evaluations, eliminating gaps in assessment coverage and ensuring continuous tracking of motor symptoms.
3Productivity
If touchscreen gesture analysis is implemented, then productivity is improved through frequent data collection, but device complexity is worsened
Solution Approach 1:
The system leverages the existing touchscreen device for multiple purposes: standard user interactions and motor skill assessment. The same touchscreen interface used for reading, emailing, and browsing also captures gesture data for PD monitoring and motor skill evaluation, eliminating the need for separate dedicated assessment devices and reducing overall system complexity.
Solution Approach 2:
The system utilizes the touchscreen device's existing sensors and processing capabilities to perform self-analysis of gesture data. The device automatically captures touch coordinates, timing, and gesture geometry, then applies machine learning algorithms to extract motor skill metrics, eliminating the need for external complex analysis hardware or manual measurement tools.
