Engineering Contradiction Analysis
1Productivity
If voice prompt method is used to move the to-be-recognized object, then the object can reach the target distance, but multiple movements are required resulting in low recognition efficiency
Solution Approach 1:
The patent replaces the voice prompt method (acoustic field) with a wind pressure generator (aerodynamic field) to directly move the to-be-recognized object. The wind pressure generator produces directed airflow that physically propels the object to the target distance, eliminating the need for multiple back-and-forth movements and significantly improving recognition efficiency.
Solution Approach 2:
The patent employs a wind pressure generator that utilizes pneumatic principles to generate controlled airflow. The generator creates positive pressure to push the object forward and negative pressure (suction) to pull it backward, enabling precise and efficient positioning at the target distance with minimal movements.
2Length of moving object
If the to-be-recognized object is far away from the recognition device, then movement distance can be large, but the captured image becomes dark and small reducing recognition accuracy
Solution Approach 1:
The patent implements a feedback mechanism where the recognition device continuously monitors the distance to the to-be-recognized object and adjusts the wind pressure generator's output accordingly. This closed-loop control ensures the object is positioned at the optimal target distance, maintaining high recognition accuracy by preventing the object from being too far or too close.
Solution Approach 2:
The system dynamically adjusts the wind pressure based on real-time distance measurements. The wind pressure generator can switch between positive pressure (for approaching) and negative pressure (for retreating), enabling precise dynamic positioning of the object at the optimal recognition distance.
3Length of moving object
If the to-be-recognized object is close to the recognition device, then the captured image can be bright and complete, but over-exposure occurs reducing recognition accuracy
Solution Approach 1:
The feedback mechanism monitors when the object approaches too close to the recognition device and automatically activates the wind pressure generator to create negative pressure (suction), pulling the object back to the optimal target distance. This prevents over-exposure and maintains recognition accuracy.
Solution Approach 2:
The system dynamically responds to distance changes by switching the wind pressure generator to negative pressure mode when the object is too close, creating a balanced dynamic positioning system that maintains the object at the optimal recognition distance regardless of initial position.
