Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detecting assemblies are used to detect errors in multi-axis machine tools, then detection capability is provided, but the structure becomes complicated making assembly and disassembly difficult
Solution Approach 1:
The detecting assembly is divided into separate functional modules: a detector unit with mounting frame containing light sources and sensors, a lens device with spherical lens, and a computer system. This segmentation allows each module to be independently assembled, tested, and replaced, simplifying the overall assembly process while maintaining detection capability.
Solution Approach 2:
The detecting assembly is designed with universal mounting capabilities that can be attached to different machine tool configurations (spindle, turntable, or both). The modular design with standardized mounting frames allows the same detector unit to serve multiple detection purposes across different axes and machine types, reducing the need for multiple specialized assemblies.
2Reliability
If conventional detecting assemblies are used to detect errors in multi-axis machine tools, then detection capability is provided, but the cost and time of detecting errors increase
Solution Approach 1:
The detector is pre-assembled with the mounting frame, light sources, and sensors in a factory setting before deployment. This preliminary assembly ensures proper alignment and calibration are already established, so when the detector is installed on the machine tool, no extensive on-site assembly or calibration is needed, significantly reducing detection time.
Solution Approach 2:
The invention replaces complex mechanical measuring mechanisms with an optical detection system using light sources, spherical lens, and sensors. This substitution eliminates the need for cumbersome mechanical fixtures and manual measurement procedures, enabling faster automated error detection while maintaining high precision.
3Reliability
If conventional detecting assemblies are used to detect errors in multi-axis machine tools, then detection capability is provided, but assembly and disassembly become difficult and inconvenient
Solution Approach 1:
The detecting assembly is divided into separate functional modules: a detector unit with mounting frame containing light sources and sensors, a lens device with spherical lens, and a computer system. This segmentation allows each module to be independently assembled, tested, and replaced, simplifying the overall assembly process while maintaining detection capability.
Solution Approach 2:
The detector incorporates self-aligning features through its optical design, where the spherical lens and sensor array automatically establish proper detection geometry when mounted. This self-service capability reduces the need for complex manual alignment procedures during assembly and disassembly, making the process more convenient and less skill-dependent.
