Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slit lamp microscope is operated remotely for telemedicine, then the accessibility to medical care is improved, but the operation difficulty increases and image quality deteriorates
Solution Approach 1:
The slit lamp microscope performs self-adjustment of illumination angle and photographing angle through automated control mechanisms, eliminating the need for remote operator intervention in complex manual adjustments. The system automatically optimizes imaging parameters based on detected eye position and orientation.
Solution Approach 2:
The system incorporates feedback mechanisms that detect the current state of the eye being examined and automatically adjust illumination and photographing angles to maintain optimal imaging conditions. This closed-loop control ensures consistent image quality regardless of operator skill level.
2Adaptability or versatility
If manual adjustment of illumination and photographing angles is used, then the flexibility in observation is improved, but the examination time increases
Solution Approach 1:
The illumination source and photographing optical system are configured to dynamically adjust their angles automatically during the examination process. The system can rapidly change between different observation angles and focal positions without requiring manual repositioning, thereby maintaining observational flexibility while significantly reducing examination time.
Solution Approach 2:
The system pre-configures multiple illumination and photographing angle positions that are optimized for different anatomical structures of the eye. During examination, the system automatically selects and transitions between these pre-optimized configurations based on the current observation requirements, eliminating the need for time-consuming manual adjustments.
3Measurement precision
If detailed corner angle observation is performed, then the diagnostic accuracy is improved, but the complexity of the apparatus increases
Solution Approach 1:
The corner angle observation function is achieved by segmenting the overall imaging system into distinct illumination and photographing subsystems with independently adjustable angles. This segmentation allows each subsystem to be optimized for its specific function while maintaining overall system manageability, achieving high diagnostic accuracy without excessive complexity.
