Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image analysis is performed with high accuracy and comprehensive examination, then measurement precision is improved, but analysis time increases causing sorting to become unsuccessful and productivity to decrease
Solution Approach 1:
The system performs preliminary actions by calculating the required analysis time before image analysis begins, and suspends conveyance in advance to ensure the analysis can be completed without affecting productivity. This allows comprehensive image examination to be performed accurately while maintaining efficient sorting operations.
Solution Approach 2:
The conveyance system dynamically adjusts by suspending transfer medium conveyance based on the calculated analysis time requirements. This dynamic control ensures that the analysis can be completed with sufficient time while maintaining optimal productivity by only suspending when necessary.
2Reliability
If uniform paper interval is set to avoid unsuccessful sorting, then sorting reliability is improved, but paper productivity decreases due to reduced conveyance speed
Solution Approach 1:
The system performs preliminary calculation of the required paper interval based on analysis time requirements before conveyance begins. By determining the appropriate interval in advance, the system ensures reliable sorting while maintaining optimal productivity without needing to reduce conveyance speed uniformly.
Solution Approach 2:
The system changes the paper interval parameter dynamically based on the specific analysis time requirements for each image. This allows the paper interval to be optimized for each individual case, ensuring reliable sorting without unnecessarily reducing overall productivity.
3Measurement precision
If analysis time is extended to handle complex image data, then measurement precision is improved, but loss of time increases affecting overall efficiency
Solution Approach 1:
The system performs preliminary calculation of the required analysis time based on image data complexity before analysis begins. This allows the system to prepare appropriately by suspending conveyance for the exact duration needed, ensuring high examination accuracy without unnecessary time loss.
Solution Approach 2:
The system uses feedback from the image data characteristics to determine the appropriate analysis time required. This feedback mechanism allows the system to adjust analysis time dynamically based on actual image complexity, ensuring sufficient time for accurate analysis of complex images while avoiding unnecessary delays for simpler images.
