Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current otoscope devices are limited in allowing untrained individuals to accurately capture high-quality images of the tympanic membrane, and there is a need for methods to guide users in image acquisition and analysis, especially for diagnosing ear-related ailments like acute otitis media, which can be challenging due to visual overlap with other conditions.
Innovation Solution
The development of methods and apparatuses that utilize a handheld imaging device connected to a mobile telecommunications device, which includes algorithms for detecting and analyzing the tympanic membrane by extracting feature values, estimating probabilities, and identifying the membrane region within images, allowing for guided image acquisition and comparison with a database for diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a standard otoscope is used for visual inspection, then the tympanic membrane can be examined, but it requires an experienced physician and is difficult for untrained individuals to perform accurately
Solution Approach 1:
The patent introduces an automated image analysis system as an intermediary between the user and the diagnosis process. The system includes algorithms that automatically detect the tympanic membrane, extract features, and compare images against a database, eliminating the need for user expertise in interpretation while maintaining diagnostic accuracy
Solution Approach 2:
The system enables untrained users to perform self-diagnosis through automated guidance. The apparatus provides real-time feedback during image capture, automatically processes the images, and delivers diagnostic results without requiring user expertise, allowing individuals to examine their own ears or their children's ears
2Ease of operation
If a handheld imaging device is used to allow untrained users to capture images, then ease of operation improves, but image quality and diagnostic reliability deteriorate
Solution Approach 1:
The system incorporates real-time feedback mechanisms that guide users during image capture. The automated analysis provides immediate feedback on image quality and proper positioning, allowing untrained users to capture diagnostic-quality images without requiring expertise in otoscopy techniques
Solution Approach 2:
The patent replaces the mechanical skill of manual otoscopy interpretation with automated digital image processing. Algorithms automatically detect anatomical structures, extract diagnostic features, and compare images against a reference database, substituting human expertise with computational analysis to maintain reliability while improving accessibility
3Productivity
If visual inspection methods are used, then the examination can be performed, but it is challenging to diagnose conditions like acute otitis media due to visual overlap with other conditions
Solution Approach 1:
The system transforms the diagnosis from qualitative visual assessment to quantitative parameter analysis. Multiple image features are extracted and measured, including color values, texture characteristics, and anatomical dimensions, providing objective data that distinguishes between conditions with similar visual appearances
Solution Approach 2:
The patent adds multiple dimensions to the diagnosis by analyzing images across different parameter spaces. Instead of relying on single visual impressions, the system evaluates multiple extracted features simultaneously and compares results against a comprehensive database, enabling differentiation of conditions that appear similar in standard visual inspection
