Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining color discrimination, such as the Farnsworth Munsell 100 hue test, are inefficient and prone to errors due to manual transcription and scoring processes, and existing automated solutions are costly and inaccurate.
Innovation Solution
The use of caps with unique passive resonant circuits and a positioning tray with an energizing circuit that selectively energizes each cap, allowing for accurate detection of cap positions using a single detector, regardless of cap orientation, and automatic data recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual transcription and scoring methods are used, then device complexity is reduced, but productivity and measurement precision deteriorate
Solution Approach 1:
The patent replaces manual mechanical transcription and scoring processes with an automated optical detection system. The system uses cameras to capture cap positions and computer vision algorithms to automatically determine color discrimination results, eliminating the need for manual copying of cap arrangements onto scoring sheets and manual calculation of errors.
Solution Approach 2:
The patent creates a digital copy of the cap arrangement through image capture. The scoring system generates a digital representation of the subject's cap arrangement and automatically compares it against the correct sequence, replacing the manual process of transcribing physical cap positions onto paper scoring sheets.
2Measurement precision
If manual scoring is performed, then device complexity is reduced, but measurement precision and reliability deteriorate
Solution Approach 1:
The patent replaces manual visual inspection and transcription with automated optical detection and image processing. The system captures images of cap arrangements, automatically identifies cap positions and orientations, and calculates discrimination scores through computer algorithms, eliminating human error in the scoring process.
Solution Approach 2:
The system provides automatic feedback by comparing the captured cap arrangement against the correct sequence and immediately generating a scored result. The system can identify and flag potential errors in cap placement and provide real-time validation of the subject's color discrimination performance.
3Measurement precision
If multiple detectors are used for each cap, then measurement precision improves, but device complexity and cost increase
Solution Approach 1:
The patent uses a single camera system to perform multiple functions: capturing the entire cap arrangement, identifying individual cap positions, determining cap orientations, and verifying cap identification. This multi-functional approach replaces what would traditionally require multiple specialized detectors, reducing system complexity while maintaining comprehensive detection capabilities.
Solution Approach 2:
The patent transitions from point-detection to area-detection by using a camera that captures the entire arrangement space. Instead of requiring multiple detectors positioned at specific locations, the system uses a single imaging device to observe the whole scene and computationally identifies cap positions through image processing algorithms.
