Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional milling tool systems are used, then the structure is simple and easy to manufacture, but the system is not robust to adapt to oscillation of the machined part, causing errors in machining
Solution Approach 1:
The patent applies dynamics by making the tool assembly movable and adjustable rather than fixed. The tool can oscillate or adapt to oscillations of the workpiece through controlled motion, allowing the system to respond dynamically to machining conditions and maintain precision despite workpiece movement or vibration.
Solution Approach 2:
The patent changes physical parameters by introducing oscillatory motion capabilities to the tool assembly. The tool can apply oscillation or adapt to oscillation with controlled amplitude and frequency, transforming a static machining system into one that can dynamically adjust its motion parameters to compensate for workpiece oscillation and maintain machining accuracy.
2Extent of automation
If multiple arm robotic tool systems are used, then automation extent is improved, but the interchangeability of arm tip tools is limited, requiring complicated steps for tool replacement
Solution Approach 1:
The patent applies universality by designing a standardized tool assembly with a universal interface that can be attached to different robotic arms. The tool assembly includes a base portion with a standardized interface that accommodates various tool types (milling tools, welding tools, material printing tools), allowing the same tool assembly to perform multiple functions across different robotic systems without complicated replacement procedures.
Solution Approach 2:
The patent applies segmentation by dividing the tool system into separate modular components: a base portion with the standardized interface and interchangeable tool portions. This segmentation allows the tool assembly to be easily disassembled and reconfigured, enabling quick replacement of different tool types while maintaining the automated robotic operation capability.
