Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rehabilitation methods for patients with inner ear balance system damage lack the ability to quantify head, eye, and postural movements during exercises, making it difficult to assess the recovery of head-eye coordination and balance function.
Innovation Solution
A system and method that concurrently measures eye movement and postural sway using a combination of eye movement tracking devices, head position detection devices, and postural sway detection devices, with data processing to determine gaze direction and postural sway, providing quantitative scores for patient assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional rehabilitation methods are used for head-eye coordination exercises, then patients can perform the exercises, but there is no way to quantify the head, eye, and postural movements to determine if patients are regaining functionality
Solution Approach 1:
The patent combines multiple measurement functions into a single integrated system. The eye movement tracking device, head position detection device, and postural sway detection device are merged into one system that simultaneously measures multiple parameters (eye position, head orientation, and postural sway) during head-eye coordination exercises, providing comprehensive quantification without requiring separate measurement systems for each parameter.
Solution Approach 2:
The measurement system is designed to perform multiple functions: tracking eye movement, detecting head position, and measuring postural sway. This multi-functional approach allows a single system to provide comprehensive quantification of all relevant movements during rehabilitation exercises, eliminating the need for multiple specialized devices and simplifying the overall measurement process.
2Loss of information
If multiple devices are used to measure eye movement, head position, and postural sway simultaneously, then comprehensive quantification is achieved, but the device complexity and difficulty of operation increase
Solution Approach 1:
The patent merges multiple detection devices into a single integrated measurement system that simultaneously captures eye movement, head position, and postural sway data. This integration eliminates the need for operators to manage separate devices for each measurement type, reducing operational complexity while maintaining comprehensive data collection.
Solution Approach 2:
The system provides real-time feedback by processing and analyzing the combined data from all sensors simultaneously. The data processing device receives signals from eye tracking, head detection, and postural sway sensors, then provides integrated feedback on patient performance, making the system easier to operate by automatically synthesizing information from multiple sources rather than requiring manual integration by the operator.
3Reliability
If conventional rehabilitation methods are used, then therapy can be administered, but there is no objective documentation of patient performance before, during, and after therapy
Solution Approach 1:
The measurement system provides continuous objective documentation of patient performance throughout the entire therapy process. By continuously tracking eye movement, head position, and postural sway before, during, and after therapy sessions, the system creates an unbroken record of patient progress, eliminating gaps in documentation and providing reliable longitudinal data for assessing rehabilitation effectiveness.
Solution Approach 2:
The system establishes a feedback loop that continuously monitors and records patient performance metrics. The data processing device analyzes measurements in real-time and provides objective feedback on patient status, creating a reliable documentation system that automatically tracks progress without requiring manual intervention, thereby reducing the perceived complexity while enhancing reliability.
4Measurement precision
If a comprehensive measurement system is implemented to assess medical conditions like TBI or concussion, then proper treatment can be determined, but the cost and complexity of the system increase
Solution Approach 1:
The patent combines multiple measurement capabilities into a single integrated system designed specifically for assessing medical conditions like TBI or concussion. By merging eye tracking, head detection, and postural sway measurement into one system, the patent achieves comprehensive and accurate medical assessment while reducing the overall complexity compared to using separate specialized devices for each measurement type.
