Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple machining heads are used to improve production efficiency, then machining efficiency is improved, but installation space expands

Engineering Contradiction:
Improvemachining efficiencyVSAvoidinstallation space
Core Design Contradiction:
ProductivityVSArea of stationary object

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If multiple machining heads are used to improve production efficiency, then machining efficiency is improved, but machining accuracy deteriorates

Engineering Contradiction:
Improvemachining efficiencyVSAvoidmachining accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
