Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature measurement device is installed on the leveler, then the temperature can be measured during operation, but the leveler blocks the measurement and the high temperature of the leveler makes installation inconvenient
Solution Approach 1:
The patent introduces an unmanned aerial vehicle (UAV) as an intermediary carrier to mount the temperature measurement device. The UAV flies above the leveler to measure the temperature of the steel plate surface without being blocked by the leveler structure, thus resolving the contradiction between measurement accessibility and measurement accuracy.
2Ease of operation
If the temperature measurement device is installed away from the leveling area, then the device can operate freely, but the temperature measurement accuracy decreases
Solution Approach 1:
The patent employs a dynamic measurement approach where the UAV flies at adjustable heights and positions above the leveling area. The system dynamically adjusts the measurement position to optimize both accessibility and accuracy, using real-time position control to maintain optimal measurement conditions while keeping the device operationally free.
3Manufacturing precision
If the leveling time is extended to ensure adequate heating, then the leveling effect improves, but the temperature may become too high or exceed requirements
Solution Approach 1:
The patent implements a feedback control system where the UAV continuously measures the steel plate temperature during the leveling process. The measured temperature data is fed back to the control system, which adjusts the leveling time and heating parameters in real-time to maintain the temperature within the optimal range, thus improving leveling quality while preventing overheating.
