Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the tool holder structure moves in a straight line along the weld seam to remove inner burrs, then the burr removal process can be performed, but burr accumulation occurs on the tool holder structure, reducing accuracy and stability
Solution Approach 1:
The patent introduces a rotating mechanism that enables the tool holder structure to move in a circular or curved path rather than a straight line. This curved motion pattern prevents burrs from accumulating in the same location, thereby maintaining removal accuracy and stability while continuing to effectively remove inner burrs from the weld seam
2Ease of manufacture
If a scraper is used to remove inner burrs from longitudinally welded pipes, then burr removal is achieved, but burrs accumulate on the scraper, affecting removal effectiveness
Solution Approach 1:
By implementing circular motion through the rotating mechanism, the scraper continuously changes its position relative to the weld seam. This prevents burrs from accumulating on the scraper surface, maintaining consistent scraping effectiveness and preventing the degradation of removal performance
Solution Approach 2:
The patent incorporates a liquid spraying system that uses fluid pressure to spray cooling liquid onto the scraper and weld seam area. This hydraulic mechanism helps flush away accumulated burrs from the scraper surface, preventing burr buildup and maintaining removal effectiveness
3Productivity
If the scraper is used continuously for burr removal, then productivity is maintained, but the scraper overheats and performance deteriorates
Solution Approach 1:
A liquid spraying system is integrated into the tool holder structure, using hydraulic pressure to deliver cooling liquid directly to the scraper and friction points. This continuous fluid flow removes heat generated during operation, preventing thermal degradation while maintaining continuous productivity
Solution Approach 2:
The cooling system utilizes the phase transition properties of liquid (evaporation and cooling effect) to absorb and remove heat from the scraper during continuous operation, preventing temperature buildup and performance deterioration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure effectively disperses burrs with cooling water, prevents accumulation, maintains scraper performance, and extends its lifespan, while ensuring precise and stable burr removal without damaging the weld seam.
Implementation Method 1
a nozzle for spraying liquid is arranged on the tool base... when the nozzle can perform an inner burr removal operation of a longitudinally welded pipe by the scraper, cooling water is sprayed at a position of the scraper
Implementation Method 2
rollers for reduced friction
