Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If auxiliary information is superimposed on digital images, then diagnostic support is provided, but color reproducibility and dynamic range deteriorate
Solution Approach 1:
The patent introduces an optical superimposition system as an intermediary between the digital image data and the user's eye. The system projects auxiliary information optically onto the real image formed by the microscope objective, allowing both the original optical image quality and digital processing benefits to coexist without compromising color reproducibility or dynamic range
Solution Approach 2:
The patent transitions from two-dimensional digital image superimposition to three-dimensional optical space superimposition. By projecting auxiliary information at specific spatial positions in the optical path, the system achieves precise overlay without the quality degradation inherent in digital processing
2Loss of information
If projection device is incorporated in observation device, then auxiliary information can be displayed, but device complexity increases significantly
Solution Approach 1:
The patent designs the optical superimposition system to serve multiple functions: it can display auxiliary information, maintain the original optical image quality, and work with existing microscope configurations. The system uses the existing objective lens and eyepiece rather than requiring separate dedicated components
Solution Approach 2:
The system leverages the existing optical path and image formation capabilities of the observation device to achieve superimposition. The objective lens and eyepiece serve dual purposes: forming the real image and enabling optical superimposition of auxiliary information without requiring entirely new hardware
3Measurement precision
If auxiliary information is superimposed on optical image, then diagnostic accuracy is improved, but user equipment must be altered
Solution Approach 1:
The patent uses the real image formed by the objective lens as an intermediary carrier. Auxiliary information is optically superimposed on this real image, which then serves as the basis for what the user perceives through the eyepiece. This approach improves diagnostic accuracy while avoiding direct modification of the user's eyepiece or observation equipment
4Ease of manufacture
If wearable device is used for superimposition, then auxiliary information can be output without altering observation device, but relative position accuracy must be maintained
Solution Approach 1:
The patent incorporates position detection mechanisms that continuously monitor the relative position between the wearable device and the observation device. This feedback information is used to dynamically adjust the superimposition position, ensuring accuracy even as the user moves or adjusts their position during observation
