Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional laboratory-based semen analysis methods are used, then measurement precision and reliability are improved, but device complexity and cost increase, making them inaccessible for home-based evaluation
Solution Approach 1:
The patent replaces complex mechanical microscopy systems with a smartphone-based optical system. The smartphone camera captures images of sperm samples, and image processing algorithms automatically analyze sperm motility, concentration, and morphology. This substitution of mechanical imaging equipment with digital imaging and computational analysis dramatically reduces device complexity and cost while maintaining evaluation accuracy.
Solution Approach 2:
The patent uses digital image copying and processing to replace direct physical measurement. Instead of requiring complex laboratory instruments to directly measure sperm parameters, the system captures visual copies of sperm samples and uses image processing algorithms to extract quantitative data. This copying approach simplifies the physical measurement process while maintaining precision through computational analysis.
2Measurement precision
If traditional laboratory-based semen analysis methods are used, then measurement precision is improved, but loss of time increases due to the need for clinical visits and laboratory processing
Solution Approach 1:
The patent enables self-service semen analysis by providing all necessary tools and instructions for home-based testing. Users can perform the entire evaluation process themselves using a smartphone and simple sample collection procedures, eliminating the need to visit clinics or laboratories. The system includes automated image capture, processing, and result interpretation, allowing individuals to independently complete the full analysis workflow.
Solution Approach 2:
The patent performs preliminary image capture and initial analysis actions at the point of sample collection (home setting) rather than requiring subsequent laboratory processing. By completing the evaluation actions immediately at the time of sample collection, the system eliminates delays associated with transporting samples to laboratories and waiting for processing results.
3Reliability
If traditional laboratory-based semen analysis methods are used, then reliability is improved, but ease of operation deteriorates, making them inaccessible for home-based use
Solution Approach 1:
The patent replaces complex mechanical operation requirements with simple digital image capture. Instead of requiring users to operate sophisticated microscopy equipment, the system only requires taking photographs of the sample using a smartphone camera. The complex analysis operations are automated through image processing algorithms, making the system both reliable and easy to operate for laypeople.
Solution Approach 2:
The patent is designed specifically for self-service operation by individuals without medical training. The system provides intuitive instructions, automated image processing, and clear result interpretation, enabling users to perform reliable semen analysis independently at home. This self-service design eliminates the need for professional laboratory technicians while maintaining evaluation reliability through standardized computational analysis.
