Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated systems are used to process pharmaceutical containers, then productivity is improved, but measurement precision deteriorates due to difficulty in detecting and measuring container dimensions
Solution Approach 1:
The patent introduces an intermediary measurement system consisting of optical sensors and cameras that indirectly measure container dimensions by detecting light reflections and shadows as containers pass through the measurement zone. This intermediary approach enables automated high-speed processing while maintaining measurement precision through optical field interactions rather than direct mechanical contact.
Solution Approach 2:
The patent replaces traditional mechanical measurement systems with optical and electromagnetic sensing systems. Instead of using physical probes or contact-based measurement devices that would slow down processing, the system uses optical sensors, cameras, and electromagnetic fields to detect container dimensions, labels, and codes at high speeds without mechanical contact.
2Measurement precision
If multiple sensors are used to detect container dimensions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent designs measurement sensors that perform multiple functions simultaneously. The same optical sensors and cameras used for dimension detection also capture images for label verification, code scanning, and container identification. This multi-functionality reduces overall system complexity while maintaining high measurement precision through a unified sensing platform.
Solution Approach 2:
The patent combines multiple measurement and detection functions into integrated sensor assemblies. Instead of separate systems for dimension measurement, label detection, and code scanning, the system merges these functions into coordinated optical sensor arrays and imaging systems that operate simultaneously, reducing device complexity while enhancing overall measurement capability.
3Reliability
If container validation is performed by comparing dimensions with reference dimensions, then reliability is improved, but loss of time increases due to validation processing
Solution Approach 1:
The patent stores reference dimension data and validation criteria in advance during system setup and container registration phases. When containers are processed, the pre-stored reference data enables immediate comparison and validation without real-time database queries or complex calculations, significantly reducing validation time while maintaining high reliability through predetermined accuracy thresholds.
Solution Approach 2:
The patent implements a streamlined validation process that skips unnecessary processing steps by using real-time optical measurement and immediate comparison with pre-stored reference dimensions. The system rapidly validates containers by comparing key dimensional parameters without full sequential checking of all possible attributes, enabling fast throughput while maintaining reliability through targeted validation of critical dimensions.
