Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a movable section is added to increase enlargement ratio, then imaging detail capability is improved, but structural stability deteriorates
Solution Approach 1:
The optical device is divided into fixed and movable sections, allowing the enlargement ratio to be adjusted by moving specific lens groups while keeping other parts stable. This segmentation enables detailed imaging without compromising overall structural stability.
Solution Approach 2:
A spacer body is introduced to define a predetermined distance between the image sensor and the fixed section, adding a dimensional constraint that stabilizes the optical path. This allows the movable section to adjust focus and enlargement while maintaining consistent imaging geometry.
2Measurement precision
If lighting is optimized for specific applications, then image quality is improved, but adaptability to different samples deteriorates
Solution Approach 1:
The lighting system is designed with multiple light sources positioned at different angles, allowing it to function effectively for various sample types including reflective surfaces, transparent samples, and rough textures. The diffusers further enhance this universality by scattering light to create optimal illumination conditions for diverse imaging applications.
3Illumination intensity
If light sources are added to illuminate samples, then visibility of sample details is improved, but light reflection on reflective surfaces worsens
Solution Approach 1:
Different light sources are positioned at specific angles tailored to the imaging requirements. For reflective surfaces, lights are positioned to minimize direct reflection into the sensor, while for rough surfaces, more direct illumination is provided. This localized optimization of lighting quality enhances visibility without excessive reflection.
Solution Approach 2:
Diffusers are introduced as intermediary elements between the light sources and the sample. These diffusers scatter the light before it reaches the sample, reducing harsh reflections while maintaining adequate illumination. This intermediary layer softens the light interaction with reflective surfaces.
4Measurement precision
If sample preparation is performed to ensure adequate observation, then analysis quality is improved, but processing costs and time worsen
Solution Approach 1:
The optical device employs adjustable parameters including movable lens sections for focus control, variable lighting angles, and configurable diffuser positions. These parameter adjustments allow the system to adapt to different sample conditions without requiring physical sample preparation, maintaining high analysis quality while eliminating preparation time.
