Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple detecting units are arranged at regular intervals to detect media thickness, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The media detection process is segmented into multiple measurement points arranged at regular intervals along the transfer path. Each detecting unit measures a specific segment of the media, and the control unit integrates these segmented measurements to determine overall authenticity, thereby improving measurement precision without requiring all detectors to operate simultaneously
Solution Approach 2:
The detecting units are arranged to measure different portions of the media as it moves through the transfer path. The system dynamically captures thickness information at multiple positions along the media's path, allowing comprehensive detection while maintaining a manageable number of sensors by utilizing the media's motion
2Reliability
If detecting units are positioned at multiple locations along the transfer path, then reliability of authenticity determination is improved, but device complexity increases
Solution Approach 1:
The authenticity verification process is divided into multiple detection stages, with each detecting unit responsible for verifying a specific portion of the media at a specific location. The control unit synthesizes results from these segmented verification stages, improving overall reliability while keeping each individual detecting unit's function simple and well-defined
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit receives detection results from multiple detecting units positioned along the transfer path and uses this feedback to make comprehensive authenticity determinations. The feedback loop allows the system to cross-validate measurements from different positions, enhancing reliability without requiring overly complex individual detectors
