Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical stereoscopic observation devices face challenges in maintaining the display of 3D images when there is a break in one of the transmission channels connecting the imaging sections to the image processing device, disrupting the acquisition of viewpoint images and hindering the user's ability to observe a 3D image effectively.
Innovation Solution
A medical stereoscopic observation device that acquires signals from multiple imaging sections via different transmission channels and switches between them for control purposes based on the state of the transmission channels, ensuring continuous observation even if one channel fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple imaging sections are connected via separate transmission channels to capture viewpoint images for 3D display, then the quality of stereoscopic observation is improved, but the reliability of the system deteriorates when one transmission channel fails
Solution Approach 1:
The transmission cable is divided into multiple independent transmission channels (first transmission channel and second transmission channel), each carrying signals from different imaging sections. This segmentation allows the system to isolate failures to specific channels while maintaining others, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The system dynamically changes the operational state of transmission channels by switching between the first and second channels based on detection results. When a channel fails, the system transitions to using the alternative channel, maintaining continuous operation and improving reliability without requiring redundant complete system duplication.
2Duration of action of moving object
If the system switches between transmission channels upon failure detection, then continuous observation capability is maintained, but the complexity of signal switching control increases
Solution Approach 1:
The detection section continuously monitors the transmission channels in advance to detect failures before they disrupt observation. The switching section is pre-configured to alternate between channels, so when a failure is detected, the system can immediately switch to the备用 channel, maintaining continuous observation without requiring complex real-time decision-making.
Solution Approach 2:
The detection section provides feedback about the state of transmission channels to the switching section. This feedback mechanism enables automatic channel switching based on real-time channel conditions, simplifying the control logic while ensuring continuous observation capability through closed-loop control.
