Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate instruments are used for various ophthalmic diagnostic tests, then measurement precision and diagnostic capability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple separate ophthalmic diagnostic instruments into a single integrated optical coherence tomography system that can perform anterior segment imaging, posterior segment imaging, and various functional tests (such as corneal topography, intraocular pressure measurement, and visual field testing) using a unified platform, thereby reducing the number of instruments from multiple separate devices to one consolidated system
Solution Approach 2:
The OCT system is designed with universal multi-functionality to perform diverse ophthalmic diagnostic tests including structural imaging of the anterior and posterior eye segments, functional assessments, and various specialized measurements, allowing a single device to replace multiple specialized instruments while maintaining comprehensive diagnostic capabilities
2Measurement precision
If multiple separate instruments are used for various ophthalmic diagnostic tests, then diagnostic capability is improved, but ease of operation deteriorates
Solution Approach 1:
By merging multiple diagnostic functions into one instrument, the system eliminates the need for patients to undergo multiple separate tests using different devices, allowing comprehensive eye examinations to be completed in a single session using one unified interface, thereby significantly improving convenience for both patients and practitioners
Solution Approach 2:
The multi-functional OCT system provides a universal platform that handles various diagnostic procedures through a single user interface and操作流程, enabling laypersons to assist with or self-administer comprehensive eye tests without needing to operate multiple different instruments, thus enhancing ease of operation
3Measurement precision
If OCT systems are administered in medical facilities by professionals, then measurement precision is improved, but accessibility and convenience deteriorate
Solution Approach 1:
The integrated OCT system is designed to enable self-service functionality where patients can perform portions of their own eye examinations or receive assistance from laypersons, reducing the mandatory requirement for professional administration while maintaining adequate measurement quality for screening and monitoring purposes, thereby improving accessibility to eye care
