Engineering Contradiction Analysis
1Adaptability or versatility
If semiconductor light sources with different wavelength characteristics are combined to produce various types of illumination light, then the adaptability to different observation purposes is improved, but the device complexity increases
Solution Approach 1:
The illumination device is divided into a fixed portion containing control circuits and a detachable light source module. This segmentation allows the light source module to be easily replaced or reconfigured for different observation purposes without modifying the complex control system, thus improving adaptability while managing device complexity.
Solution Approach 2:
The control circuit is designed to universally control multiple types of light sources (first and second light sources with different wavelength characteristics) through a standardized interface. The control circuit determines driving conditions based on characteristic information stored in storage units, enabling one control system to handle multiple light source configurations for various observation purposes.
2Adaptability or versatility
If multiple light sources with different wavelength characteristics are combined, then the illumination light characteristics can be optimized for various observation methods, but the difficulty of controlling and coordinating the light sources increases
Solution Approach 1:
The control circuit reads characteristic information (such as wavelength characteristics) from storage units associated with each light source, and based on this feedback information, automatically determines appropriate driving conditions for each light source. This feedback mechanism simplifies the control coordination by using stored characteristic data to guide the control decisions.
Solution Approach 2:
Characteristic information of each light source is pre-stored in storage units before operation. This preliminary action of storing wavelength and other characteristic data allows the control circuit to quickly determine driving conditions without real-time complex calculations, reducing control coordination difficulty while maintaining optimized illumination characteristics.
3Ease of operation
If a detachable light source module is used to supply light to the illumination device, then the ease of operation and maintenance is improved, but the reliability of light source connection may deteriorate
Solution Approach 1:
The light source module is designed as a nested structure where the light sources and their characteristic information storage are integrated within a single detachable module that connects to the main illumination device. This nesting ensures that when the module is connected, all components (light sources and their control data) are properly aligned and connected, maintaining reliability while enabling easy replacement.
