Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple photographing units are used to detect overlapping sheets from multiple angles, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The detection system is divided into multiple photographing units, each responsible for capturing images from specific angles (vertical and side directions). This segmentation allows comprehensive detection of overlapping sheets while maintaining manageable complexity through modular architecture
Solution Approach 2:
The system transitions from single-view detection to multi-dimensional detection by adding vertical and side photographing angles. This dimensional expansion enables accurate detection of overlapping sheets that cannot be detected from a single perspective
2Reliability
If images are captured and analyzed in real-time during transport, then overlapping sheets are detected promptly, but processing time increases
Solution Approach 1:
The system captures images at multiple predetermined angles and positions during the transport process, performing detection actions in advance before the sheets reach the stacking position. This allows timely identification and response to overlapping conditions
Solution Approach 2:
The photographing units continuously capture images during the transport process, maintaining constant monitoring of sheet positions. This continuous detection ensures no overlapping events are missed while enabling real-time intervention

AI summary
An object overlap detection apparatus includes one or more photographing units configured to photograph objects from multiple angles. A determining unit is configured to determine whether there are overlapping objects by analyzing an image obtained by photographing the objects in a vertical direction using the one or more photographing units. The determining unit is also configured to determine whether there are overlapping objects by analyzing an image obtained by photographing a side of using the one or more photographing units. A controller is configured to receive information indicating whether the objects overlap from the determination units and to control one or more of an alarm signal, an operation of the photographing units, and transport of the objects.
