Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional concussion testing methods (Impact Test) are used, then measurement precision is maintained, but device portability and testing speed deteriorate
Solution Approach 1:
The patent extracts the core measurement function from the complex traditional testing system. By isolating the visual motion detection threshold measurement as a standalone portable test, the system achieves concussion detection capability without requiring the full traditional testing equipment, thus improving portability while maintaining essential diagnostic accuracy
Solution Approach 2:
The patent creates a simplified copy of the concussion detection function. Instead of using the complete traditional Impact Test system, it implements a portable version that copies the essential measurement capability (visual motion detection) to detect concussion indicators, achieving portability while preserving diagnostic relevance
2Measurement precision
If traditional concussion testing methods are used, then measurement precision is maintained, but testing time increases
Solution Approach 1:
The patent extracts only the essential visual motion detection component from the full 30-minute traditional testing protocol. This extracted sub-test can be completed in significantly less time while still providing meaningful concussion detection data, thus reducing testing time while maintaining measurement precision for the specific function performed
Solution Approach 2:
The patent implements a streamlined version of concussion testing that skips unnecessary steps of the traditional protocol. By focusing directly on visual motion detection threshold measurement and using automated computer-based presentation, the system rushes through the essential measurement in less time while maintaining diagnostic accuracy
3Measurement precision
If traditional concussion testing methods are used, then measurement precision is maintained, but ease of operation deteriorates
Solution Approach 1:
The patent implements a computer-based automated system that performs the measurement without requiring a qualified professional to conduct the full traditional test. The system guides the patient through visual motion detection tasks and automatically processes results, making the test self-administerable or easily administered by non-specialists while maintaining measurement precision
Solution Approach 2:
The patent creates a simplified copy of the professional testing process that can be administered more easily. By copying only the essential visual detection tasks into an automated computer-based format, the system removes barriers to operation while preserving the core measurement capability
Data Source
AI summary
A patient's visual motion detection threshold is measured by displaying on a display screen a fixation target on a background image. The characteristics of a threshold wave pattern displayed against the background image is adjusted while displaying the fixation target. An indication is received when the threshold wave pattern becomes visible to the patient while adjusting the characteristics of the threshold wave pattern. The patient's measured visual motion detection threshold is established based on receiving the indication.
