Innovation Solution
An ophthalmologic system that includes an ophthalmologic apparatus with a measurement unit, a display imaging device, and a terminal device connected via a network, allowing transmission of non-image information and capturing of entire screen images for integration and remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all measurement information including images is transmitted to the remote terminal, then the completeness of examination data is improved, but the network load and processing time increase significantly
Solution Approach 1:
The patent segments measurement information into two categories: image information (captured by the display imaging device) and non-image information (measurement data from the measurement unit). This segmentation allows selective transmission of only necessary data to the remote terminal, reducing network load and processing time while maintaining examination completeness.
Solution Approach 2:
The patent extracts only the essential non-image measurement information from the complete measurement data set for transmission to the remote terminal. By taking out only the critical numerical data and parameters needed for remote diagnosis, the system minimizes data transmission volume and processing requirements while preserving medical examination value.
2Speed
If image information from the display screen is captured and transmitted, then real-time visual feedback is improved, but the data transmission volume and network bandwidth requirements increase
Solution Approach 1:
The patent uses a display imaging device to capture images of the display screen, creating a visual copy of the measurement results for transmission to the remote terminal. This copying approach provides real-time visual feedback to the remote examiner without requiring transmission of the full-resolution original measurement data, thus reducing network bandwidth requirements while maintaining diagnostic capability.
3Adaptability or versatility
If the examiner operates the apparatus remotely from a different location, then infection prevention and telemedicine capability are improved, but the ease of operation and real-time control are reduced
Solution Approach 1:
The patent implements a feedback mechanism where measurement information and display screen images are continuously transmitted from the ophthalmologic apparatus to the remote terminal. This real-time feedback loop allows the remote examiner to monitor measurement progress and results, enabling effective remote operation despite the physical separation between examiner and apparatus.
Solution Approach 2:
The patent introduces a terminal device as an intermediary between the remote examiner and the ophthalmologic apparatus. This intermediary receives measurement information and display images, presents them to the examiner, and transmits operational commands back to the apparatus, thereby enabling remote operation while maintaining ease of use through a user-friendly interface.
