Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical coherence tomography (OCT) systems require multiple instruments for various ophthalmic diagnostic tests, which are typically administered in medical facilities by professionals, limiting accessibility and convenience.
Innovation Solution
Integration of an OCT device with display, input, and central processor to perform a range of ophthalmic tests in a single, self-administerable or layperson-assisted instrument, enabling scans and analyses of anterior and posterior eye regions, and outputting diagnostic reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate instruments are used for various ophthalmic diagnostic tests, then measurement precision and diagnostic capability are maintained, but device complexity increases and accessibility decreases
Solution Approach 1:
The patent combines multiple separate ophthalmic diagnostic instruments into a single integrated system that performs OCT imaging, visual acuity testing, and other ophthalmic examinations through a unified platform with shared optical paths and processing systems
Solution Approach 2:
The integrated ophthalmic testing system is designed to perform multiple diagnostic functions including OCT scans of anterior and posterior eye regions, visual acuity measurements, and other ophthalmic tests through a single versatile instrument that serves various diagnostic purposes
2Adaptability or versatility
If multiple separate instruments are used for ophthalmic tests, then comprehensive diagnostic coverage is achieved, but ease of operation deteriorates due to requiring multiple devices
Solution Approach 1:
The system merges multiple diagnostic functions into one unified instrument that can perform OCT imaging, visual acuity testing, and other ophthalmic examinations through a single operational interface and integrated hardware platform
Solution Approach 2:
The integrated system provides universal ophthalmic diagnostic capability, allowing a single instrument to perform comprehensive eye examinations including anterior segment imaging, posterior segment imaging, and functional vision tests through multiple operational modes
3Measurement precision
If OCT scans are administered in medical facilities by professionals, then measurement precision is maintained, but accessibility and convenience worsen
Solution Approach 1:
The integrated ophthalmic testing system enables self-administered OCT scans and other eye examinations by patients without requiring professional administration, through automated guidance interfaces and simplified operational procedures that maintain diagnostic quality
Solution Approach 2:
The system provides universal accessibility for ophthalmic testing by combining professional-grade diagnostic capabilities with user-friendly operation, allowing both self-administered and professionally-assisted examinations through the same integrated platform
