Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a laser beam is used to remove material from the workpiece, then material removal is achieved, but the laser beam deviates from the intended path due to reflections and refractions at the material surface
Solution Approach 1:
The patent introduces a monitoring camera as an intermediary device to capture images of the material surface and calculate the actual position of the laser beam. This intermediary system detects deviations caused by reflections and refractions, allowing the control system to compensate for these errors and maintain cutting precision.
2Ease of operation
If the focus position of the laser beam is fixed, then the system is simple to operate, but the laser beam may focus inside or outside the workpiece depending on material variations
Solution Approach 1:
The patent implements an automated feedback system where the monitoring camera captures images of the cut surface, and the control system calculates the actual focus position based on these images. This feedback loop automatically adjusts the focus position to account for variations in material thickness and properties, eliminating the need for manual focus adjustment while maintaining high precision.
3Manufacturing precision
If manual focus adjustment is required for different materials, then focus precision can be optimized, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent enables the system to automatically determine and adjust the focus position based on real-time images captured by the monitoring camera. The control system performs calculations to identify the optimal focus position without requiring manual intervention, allowing the system to adapt to different materials automatically while maintaining precision.
4Device complexity
If the laser beam path is not monitored, then the system is simpler, but the actual cutting position deviates from the intended path
Solution Approach 1:
The patent introduces a monitoring camera that continuously captures images of the laser beam position and material surface. The control system processes these images to calculate the actual beam position and compares it with the intended path, providing feedback that enables real-time compensation for deviations caused by reflections and refractions.
5Ease of operation
If focus position is not adjusted for material variations, then the operation is simpler, but the cut quality deteriorates when the beam focuses inside or outside the workpiece
Solution Approach 1:
The system automatically adjusts the focus position by capturing images of the cut surface with the monitoring camera and calculating the optimal focus point based on the material's actual properties. This self-adjusting mechanism maintains high cut quality across different materials without requiring manual focus adjustment, preserving operational simplicity.

AI summary
A structure body cutting system (1) includes a cutter system (2) mounted on a cutting side trailer (20) and configured to cut a blade (8) to be cut, and a feeder system (5) mounted on a feeding side trailer (50) and configured to send out the blade (8) to the cutter system (2). The blade (8) is placed so as to straddle between the cutter system (2) and the feeder system (5). The feeder system (5) sends out the blade (8) to the cutter system (2) as the feeding side trailer (50) comes close to the cutting side trailer (20). The cutter system (2) cuts the blade (8) into a plurality of cut segments by cutting the blade (8) sent out from the feeder system (5) .
