Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple machining heads are used to improve production efficiency, then machining efficiency is improved, but installation space expands
Solution Approach 1:
The patent transitions from horizontal arrangement of multiple machining centers to a vertical arrangement where machining heads are stacked in the height direction. This dimensional change allows multiple machining operations to be performed simultaneously without increasing the horizontal footprint of the machine tool, thus improving productivity while minimizing installation space expansion.
2Productivity
If multiple machining heads are used to improve production efficiency, then machining efficiency is improved, but machining accuracy deteriorates
Solution Approach 1:
The patent divides the machining system into independent machining head units, each capable of performing precise machining operations. Each machining head is equipped with its own control system and positioning mechanisms, allowing independent operation and maintenance of machining accuracy for each head while collectively improving productivity through parallel processing.
Solution Approach 2:
The machining heads are designed with universal functionality to perform various machining operations (milling, drilling, tapping, etc.) using different tools. This multi-functionality allows a single machining head to replace multiple specialized machines, maintaining machining accuracy across diverse operations while improving overall system productivity.
