Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If roundness measurement and surface roughness measurement are performed as independent measurements, then each measurement can be conducted with dedicated measurement conditions, but the measurement workload increases and measurement efficiency decreases
Solution Approach 1:
The patent combines roundness measurement and surface roughness measurement into a single integrated measurement process. The measurement conditions setting unit uses data from roundness measurement to automatically determine appropriate conditions for surface roughness measurement, allowing both measurements to be performed efficiently in one operation rather than as separate independent measurements.
Solution Approach 2:
The patent performs roundness measurement first to establish measurement conditions for subsequent surface roughness measurement. The measurement conditions setting unit utilizes the data acquired from roundness measurement (such as workpiece geometry and surface characteristics) to pre-determine optimal sampling intervals, measurement ranges, and other parameters before conducting surface roughness measurement, thereby streamlining the overall process.
2Measurement precision
If measurement conditions are set manually based on operator experience, then measurement accuracy can be maintained, but the burden on the operator increases and consistency decreases
Solution Approach 1:
The patent implements an automated measurement conditions setting system that uses data from roundness measurement to automatically determine appropriate conditions for surface roughness measurement. The measurement conditions setting unit functions autonomously to select sampling intervals, measurement ranges, and other parameters based on the acquired data, eliminating the need for manual operator intervention and ensuring consistent, accurate measurements without relying on operator experience.
Solution Approach 2:
The system uses data acquired from roundness measurement as feedback to automatically adjust and set measurement conditions for surface roughness measurement. The measurement conditions setting unit analyzes the roundness measurement data (including workpiece geometry and surface characteristics) and uses this information to optimize measurement parameters, creating a closed-loop system that improves both accuracy and ease of operation.
3Device complexity
If data from roundness measurement is not utilized for surface roughness measurement, then each measurement remains independent and simple, but measurement efficiency and data utilization are reduced
Solution Approach 1:
The patent makes the roundness measurement data serve multiple purposes: it is used not only for roundness evaluation but also as the basis for setting measurement conditions for surface roughness measurement. This multi-functional use of the same data reduces redundant measurements and optimizes the overall measurement process, improving efficiency without significantly increasing system complexity.
