Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single sensor is provided close to the binding machine to detect reinforcing bars, then the binding position can be determined, but sensor detection errors occur due to the movement of the binding machine during binding work
Solution Approach 1:
The patent divides the detection function into multiple sensors (first sensor, second sensor, third sensor, fourth sensor) positioned at different locations. Each sensor detects reinforcing bars from different perspectives, and their results are combined to determine binding positions, eliminating the reliance on a single sensor that would be affected by machine movement.
Solution Approach 2:
The patent positions sensors in multiple spatial dimensions (apart from each other along different directions) rather than concentrating them in one location. This multi-dimensional arrangement allows the system to detect reinforcing bars from various angles and positions, compensating for the binding machine's movement during operation.
2Reliability
If multiple sensors are positioned apart from each other to eliminate detection errors, then detection reliability improves, but device complexity increases
Solution Approach 1:
The multiple sensors serve universal detection functions - each sensor can detect both first reinforcing bars (extending in the first direction) and second reinforcing bars (extending in the second direction). This multi-functionality reduces the need for specialized sensors for different purposes, simplifying the overall system design despite using multiple sensors.
Solution Approach 2:
The control device processes detection results from all sensors and uses this feedback information to accurately determine binding positions. The system continuously monitors reinforcing bar positions through multiple sensors and adjusts binding operations accordingly, creating a closed-loop control system that manages complexity through intelligent processing.
