Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic examination methods are inefficient in quickly and accurately determining eye diseases due to reliance on expensive equipment and fixed examination positions, leading to poor examination environments and potential optical interference errors.
Innovation Solution
A head-mounted display device with a virtual reality-based system that optically separates the left and right eye areas, allowing for digital ophthalmic examinations without specific equipment, enabling objective and automatic data collection and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional eye examination equipment is used, then examination accuracy can be maintained, but examination speed and efficiency deteriorate due to manual analysis requirements
Solution Approach 1:
The patent replaces manual mechanical examination processes with an automated head-mounted display system that captures ocular images and automatically analyzes them using image processing algorithms, eliminating the need for manual image analysis while maintaining diagnostic accuracy
Solution Approach 2:
The system enables self-examination functionality where the head-mounted device automatically performs image capture, processing, and analysis without requiring external examination equipment or manual intervention, allowing rapid consecutive examinations
2Stability of the object's composition
If fixed examination equipment is used, then examination stability is maintained, but examination environment quality deteriorates due to restricted patient movement
Solution Approach 1:
The patent transitions from fixed stationary examination equipment to a dynamic head-mounted display system that moves with the patient, allowing examinations to be performed in various positions and environments while maintaining measurement stability through the device's integrated sensor system
Solution Approach 2:
The head-mounted display device serves multiple functions including image capture, optical axis alignment, and stabilization, making it adaptable to various examination scenarios and patient positions without requiring specialized fixed equipment
3Measurement precision
If conventional examination setup is used, then optical measurement can be performed, but optical interference errors increase due to lack of proper isolation
Solution Approach 1:
The patent divides the examination field into separate left and right eye areas using optical isolation structures within the head-mounted display, preventing cross-contamination of light between eyes and eliminating optical interference that would affect measurement accuracy
Solution Approach 2:
The patent introduces optical isolation elements as intermediary structures between the light source and the ocular structures being examined, blocking stray light and reflections that would cause optical interference while allowing the necessary examination light to pass through
