Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital magnification is used to increase total imaging scale, then image magnification is improved, but light sensitivity is not enhanced and no additional image information is provided
Solution Approach 1:
The system dynamically adjusts the optical imaging scale as a manipulated variable in response to changing light conditions. By modifying the optical magnification parameter based on detected light intensity, the system ensures sufficient light reaches the detector while maintaining appropriate image scale, thereby improving light sensitivity without sacrificing magnification quality
Solution Approach 2:
The system implements feedback control by continuously monitoring light intensity and adjusting the optical imaging scale accordingly. The control unit receives light intensity signals and modifies the optical magnification to maintain optimal imaging conditions, ensuring that light sensitivity is enhanced while preserving image information quality
2Measurement precision
If optical imaging scale is increased to improve image detail, then measurement precision is improved, but light sensitivity deteriorates
Solution Approach 1:
The optical imaging scale is made dynamic rather than fixed. The system continuously adapts the optical magnification based on real-time light intensity measurements, allowing the imaging scale to vary within an optimal range that balances image detail quality with sufficient light sensitivity for the imaging detector
Solution Approach 2:
The system changes the optical imaging scale parameter in response to light intensity variations. By adjusting this parameter dynamically, the system maintains optimal image detail while ensuring adequate light sensitivity, resolving the contradiction between these two requirements
3Measurement precision
If maximum optical magnification is utilized, then image detail is improved, but automatic adaptation to light conditions is lost
Solution Approach 1:
The system employs feedback control where light intensity measurements automatically trigger adjustments to the optical imaging scale. This feedback mechanism enables the system to adapt to varying light conditions while maintaining optimal image detail, eliminating the need for manual intervention
Solution Approach 2:
The system performs self-adjustment by automatically modifying the optical imaging scale based on detected light intensity. The control unit autonomously manages the balance between image detail and light sensitivity without requiring user input, enabling the system to serve itself in adapting to changing imaging conditions

AI summary
A microscopy method is for producing an electronic image of an object, wherein the object is imaged with an adjustable optical imaging scale on an image detector. The method includes: selecting a parameter for the electronic image, wherein the parameter can be influenced by the optical imaging scale and differs from the image field dimensions, and setting a setpoint value range for the parameter, setting a total imaging scale for the electronic image, wherein adjusting or controlling the parameter of the electronic image is implemented such that, at the same time, the parameter of the electronic image lies in the specified setpoint value range with a tolerance and the set total imaging scale is obtained, wherein the optical imaging scale forms a basis for a manipulated variable of the adjustment or closed-loop control and a digital image magnification is carried out on the basis of the set total imaging scale.
