Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video signals are transferred using cables in endoscope systems, then signal transmission reliability is ensured, but cable installation becomes cumbersome and operational flexibility is reduced
Solution Approach 1:
The patent replaces the mechanical cable-based video signal transmission system with a wireless transmission system. The wireless transmitter and receiver eliminate the need for physical cable connections between the endoscope system and monitors, thereby improving ease of operation and reducing cable installation complexity while maintaining signal transmission reliability through standardized wireless communication protocols.
2Adaptability or versatility
If multiple monitors are arranged according to operator's standing position changes, then adaptability to different observation positions is improved, but cable management becomes more complex
Solution Approach 1:
The wireless transmission system allows monitors to be freely positioned around the operating area without being constrained by cable routing. Each monitor equipped with a wireless receiver can independently receive video signals from the wireless transmitter, enabling flexible repositioning according to the operator's standing position changes during surgery without increasing cable management complexity.
3Manufacturing precision
If high-definition 3D video signals with ancillary information are transmitted, then observation quality is improved, but transmission bandwidth requirements increase
Solution Approach 1:
The wireless transmission system segments the high-definition 3D video signal into standard SDI signal formats with ancillary information channels. By utilizing established SDI signal standards, the system efficiently packages video data with metadata (such as 3D format information) in dedicated ancillary data sections, achieving high observation quality without proportionally increasing overall transmission bandwidth requirements.
