Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching and setting adjustment are used when transitioning between internal and external light sources, then device complexity is reduced, but ease of operation deteriorates and productivity decreases
Solution Approach 1:
The video processor automatically detects connection status of light guides and determines which light source to use without manual intervention. The system self-adjusts illumination settings based on detected external light source characteristics, eliminating the need for operator involvement in light source switching and parameter adjustment.
Solution Approach 2:
The system continuously monitors connection status through connection detectors and receives feedback about external light source characteristics via communication. Based on this feedback, the video processor dynamically adjusts illumination settings and switches between light sources automatically, creating a closed-loop control system.
2Productivity
If automated light source determination is implemented, then ease of operation improves and productivity increases, but device complexity increases
Solution Approach 1:
The video processor integrates multiple functions into a single device: it processes endoscopic images, detects light guide connections, communicates with external light sources, determines appropriate illumination settings, and automatically switches between light sources. This consolidation eliminates the need for separate manual control mechanisms while achieving automated operation.
3Adaptability or versatility
If communication with external light source device is added, then adaptability improves, but device complexity increases
Solution Approach 1:
A communication controller acts as an intermediary between the video processor and external light source devices. This dedicated component handles all communication protocols, data exchange, and coordination, allowing the video processor to adapt to different external light sources without increasing overall system complexity.

AI summary
A video processor that is connectable to an endoscope and an external light source device that supplies illumination light to a light guide of the endoscope includes: a connection detector that detects a presence/absence of connection between the video processor and the light guide of the endoscope; an internal light source unit that supplies the illumination light to the light guide of the endoscope; a communication controller that performs communication with the external light source device, and obtains device data of the external light source device; and a utilized light source determination unit that determines a light source that supplies the illumination light to the light guide of the endoscope in accordance with a detection result of the connection detector or a state of obtainment of the device data of the communication controller.
