Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual counting of pleats is used, then the process is simple and requires minimal equipment, but the counting is time-consuming and prone to errors
Solution Approach 1:
The patent replaces the manual mechanical counting process with an automated optical sensing system. Sensors detect the passage of pleats through the corrugated material, automatically recording the count without human intervention. This substitution eliminates both the time consumption and human error associated with manual counting while maintaining measurement accuracy.
2Reliability
If manual counting of pleats is used, then the equipment required is minimal, but the operation is tedious and error-prone
Solution Approach 1:
The pleat counting system is designed to operate autonomously without requiring manual intervention. The sensors automatically detect pleats as they pass through the material, the system self-records the counts, and the data is automatically processed. This self-service capability eliminates the tedious nature of manual counting while ensuring reliable and accurate results.
3Productivity
If automated sensor-based pleat detection is implemented, then counting accuracy and productivity are improved, but device complexity increases
Solution Approach 1:
The patent employs sensors that serve multiple functions: detecting the presence of pleats, determining their passage timing, and providing data for count calculation. This multi-functionality reduces the need for separate dedicated components for each task, thereby limiting the increase in device complexity while maintaining high productivity and accuracy.
