Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of illumination angle and slit width is performed when switching front lenses, then the separation state between illumination and observation light can be achieved, but the setup time is prolonged and the operation becomes complex
Solution Approach 1:
The control unit stores optimal illumination angle and slit width settings for each front lens type in advance. When a front lens is selected, the system automatically retrieves and applies the pre-stored settings, eliminating the need for manual adjustment and reducing setup time while ensuring reliable light separation.
Solution Approach 2:
The system detects which front lens is currently installed and automatically adjusts illumination parameters based on this information. This feedback mechanism ensures the correct separation state is achieved without manual intervention, resolving the contradiction between reliability and time loss.
2Reliability
If manual adjustment of illumination parameters is performed, then the separation state between illumination and observation light can be achieved, but the ease of operation is reduced
Solution Approach 1:
The system performs self-adjustment by automatically detecting the installed front lens and setting the illumination angle and slit width without operator intervention. This eliminates the complexity of manual adjustment while ensuring reliable light separation, directly resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The control unit receives feedback about the installed front lens and automatically configures the illumination system accordingly. This automated feedback loop ensures reliable separation state while greatly improving ease of operation.
3Measurement precision
If different front lenses are used for different observation positions, then the observation quality is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it detects the installed front lens, retrieves the appropriate settings, and automatically adjusts the illumination parameters. This multi-functionality allows the system to handle different front lenses and observation positions without increasing physical device complexity, while maintaining high observation quality.
Solution Approach 2:
The system uses feedback from the front lens identification to automatically configure optimal settings for different observation positions. This intelligent feedback mechanism enables high-quality observation across multiple positions without requiring complex manual configuration procedures.
4Productivity
If automatic adjustment based on identification information is implemented, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The control unit automatically detects which front lens is installed and retrieves the corresponding optimal settings from stored data. This automated feedback-based adjustment system significantly improves productivity by eliminating manual setup time, while the complexity added is minimal and confined to the control system.
Solution Approach 2:
Optimal illumination parameters for different front lenses are pre-calculated and stored in the control unit. This preliminary preparation enables rapid automatic adjustment when lenses are switched, greatly improving productivity without requiring complex real-time calculations or additional hardware.

AI summary
Provided is an operation microscope apparatus for easily and speedily obtaining a suitable separation state between illumination light and observation light in a case where a front lens is replaced by another one. An illumination optical system includes a slit plate in which slit holes having different slit widths are formed. Each of a plurality of front lens having different refractive powers is integrally formed with corresponding one of storing sections. One of the storing sections is attached to an elevation regulating member. The elevation regulating member includes micro-switches. Each of the storing sections includes a protruding portion for turning on corresponding one of the micro-switches at the time of attachment. A control unit sets an illumination angle of the illumination light and a slit width of a slit based on a detection signal from a micro-switch which becomes an on state.
