Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual methods are used to remove burrs, then labor flexibility is maintained, but production efficiency is low and labor consumption is high
Solution Approach 1:
The patent replaces manual mechanical burr removal with an automated milling device that uses a grinding ejector pin machine. The device features an automatic feeding mechanism that feeds multiple raised floors into position, and an automated milling cutter that removes burrs from the legs and intersecting ribs without manual intervention, thereby dramatically improving production efficiency while reducing labor consumption.
Solution Approach 2:
The milling device is divided into functional segments: a feeding mechanism that handles multiple raised floors, a milling mechanism with rotating cutters, and a control system. This segmentation allows each component to be optimized independently and enables automated batch processing of multiple raised floors simultaneously, resolving the contradiction between automation and productivity.
2Productivity
If automated milling is implemented, then production speed increases, but device complexity increases
Solution Approach 1:
The milling device is designed as a multi-functional integrated system that combines feeding, positioning, and milling operations in a single machine. The grinding ejector pin machine can process multiple raised floors in sequence with automatic feeding, and the milling mechanism can handle various burr configurations on different parts of the raised floors (legs and intersecting ribs), thereby achieving high production speed without proportionally increasing device complexity.
3Productivity
If multiple milling devices are arranged in matrices, then batch processing capability increases, but spatial requirements and device complexity increase
Solution Approach 1:
The patent arranges multiple milling devices in a compact matrix configuration where devices are nested or closely integrated within the same machine footprint. The feeding mechanism feeds raised floors into positions for multiple milling cutters that operate simultaneously or in rapid sequence, enabling batch processing of multiple raised floors without requiring proportional increases in spatial arrangement, thereby improving productivity while controlling the area occupied.
