Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring patient recovery from musculoskeletal injuries lack objective and accurate measures of range of motion, relying on subjective pain estimation and lacking data-driven approaches to predict recovery time and treatment effectiveness.
Innovation Solution
Development of wearable electronic devices integrated into eyeglass frames that use sensors like accelerometers, magnetometers, and gyroscopes to objectively measure cervical range of motion, track progress over time, and provide data for personalized physical therapy regimes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If subjective pain estimation is used to gauge recovery progress, then the method is simple and easy to implement, but the measurement accuracy and objectivity deteriorate
Solution Approach 1:
The patent replaces the subjective mechanical assessment method (pain estimation) with an electronic sensing system using accelerometers, magnetometers, and gyroscopes to objectively measure cervical range of motion. This substitution transforms the measurement from subjective patient reporting to objective sensor-based data collection, resolving the contradiction between ease of operation and measurement accuracy.
2Device complexity
If no database of historical movement data is available, then the system remains simple, but the ability to predict recovery time and treatment effectiveness deteriorates
Solution Approach 1:
The patent implements preliminary data collection and storage functionality, creating a database of historical movement data before it is needed for predictions. The system is designed to accumulate recovery data over time and use this pre-collected information to predict recovery timelines and treatment effectiveness, eliminating the need for complex real-time analysis while maintaining predictive capability.
3Measurement precision
If comprehensive movement data is collected to accurately diagnose injuries, then the measurement precision improves, but the device complexity and data processing requirements increase
Solution Approach 1:
The patent merges multiple sensing functions (accelerometer, magnetometer, gyroscope) into a single integrated wearable device. By combining these sensors and their data processing capabilities into one unified system worn by the patient, the device achieves comprehensive movement data collection for accurate diagnosis while maintaining relative simplicity through integration rather than multiple separate devices.
