Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If chemical analysis is used to identify pills, then identification accuracy is improved, but time consumption and cost increase significantly
Solution Approach 1:
The patent replaces the mechanical/chemical analysis system with an optical imaging system. Instead of using chemical reagents and manual examination, the system uses digital images captured by cameras to identify pills. This substitution dramatically reduces identification time while maintaining accuracy, as the optical system can process multiple pill characteristics simultaneously without the time-consuming steps of chemical preparation and analysis.
Solution Approach 2:
The patent creates digital copies (images) of pills for identification purposes. Instead of analyzing the physical pill through chemical methods, the system captures digital images that replicate the pill's visual characteristics. These copies can be stored, transmitted, and analyzed without affecting the original pill, enabling rapid identification while preserving the physical evidence.
2Measurement precision
If chemical analysis is used to identify pills, then identification accuracy is improved, but the pill is destroyed during analysis
Solution Approach 1:
The patent creates digital copies (images) of pills for identification purposes. Instead of analyzing the physical pill through chemical methods, the system captures digital images that replicate the pill's visual characteristics. These copies can be stored, transmitted, and analyzed without affecting the original pill, enabling rapid identification while preserving the physical evidence.

3Productivity
If automated optical identification system is implemented, then identification speed and automation are improved, but system complexity increases
Solution Approach 1:
The patent implements a multi-functional system where a single device performs multiple operations: capturing images from multiple angles, rotating the pill, providing illumination, and transmitting data. By integrating these functions into one automated system, the patent achieves high identification speed without proportionally increasing complexity, as the same hardware components serve multiple purposes in the identification process.
4Measurement precision
If multiple images from different angles are captured, then identification accuracy is improved, but data transmission requirements increase
Solution Approach 1:
The patent extracts only the essential identification features from the captured images rather than transmitting the complete image data. By identifying and transmitting only the critical characteristics needed for pill identification (such as shape, color, markings, and scoring), the system maintains high identification accuracy while significantly reducing the data transmission volume and storage requirements.
