Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If automated sperm motility testing devices are used, then measurement precision and consistency are improved, but device complexity and cost increase
Solution Approach 1:
The patent creates an optical copy of the microscopic view by using a camera to capture images of the sperm sample. The camera module records visual information that replicates what would be seen through a microscope, allowing automated analysis without requiring complex microscope optics. This copying approach maintains measurement precision while simplifying the device structure.
Solution Approach 2:
The patent replaces the mechanical/optical microscope system with an electronic imaging system. Instead of using complex lens systems and optical pathways to magnify and view sperm motion, the invention uses a camera module with basic optics to capture images that are then processed electronically. This substitution reduces mechanical complexity while maintaining the ability to measure sperm motility accurately.
2Measurement precision
If expensive microscope systems are used for sperm assessment, then measurement precision is improved, but ease of operation and accessibility worsen
Solution Approach 1:
The patent implements automated image processing and analysis that performs sperm counting and motility assessment without requiring user expertise. The system automatically captures images, processes them through algorithms, and generates results, making the device self-sufficient in performing complex analytical tasks. This eliminates the need for trained personnel to operate or interpret results from expensive microscope systems.
Solution Approach 2:
The patent changes the operational parameters from manual microscope adjustment and visual assessment to automated electronic capture and digital analysis. By transforming the measurement process into electronic parameters (image data, pixel analysis, automated counting), the system becomes easier to operate while maintaining precision, as the automated processing removes the need for skilled manual operation.
3Measurement precision
If traditional laboratory-based sperm testing is used, then measurement precision is maintained, but ease of operation and convenience worsen due to laboratory requirements
Solution Approach 1:
The patent makes the sperm testing device universal by enabling it to function in multiple settings - both laboratory and home environments. The simplified optical system using a camera module rather than requiring specialized laboratory microscopes allows the device to be deployed anywhere with basic lighting conditions. This multi-functionality maintains measurement precision while enabling convenient home use for privacy and accessibility.
Solution Approach 2:
The patent employs a simplified, lower-cost optical system that can be manufactured more economically than traditional microscope systems. By using a camera module with basic lenses instead of complex microscope optics, the device becomes affordable for home use while still providing accurate fertility assessments. The reduced cost enables widespread distribution and home-based testing without compromising measurement precision.
