Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually compare stored measurement data with reference data on a PC, then comparison accuracy is maintained, but time consumption increases significantly
Solution Approach 1:
The patent combines the measurement device with reference data storage and processing capabilities, merging previously separate functions (measurement, data storage, reference data access, and comparison) into a single integrated system. This allows users to compare measurement results with reference data directly on the device without manual data transfer to a PC, maintaining comparison accuracy while significantly reducing time consumption.
2Manufacturing precision
If users store and manually transfer measurement data to a PC for comparison, then data processing thoroughness is ensured, but operational complexity increases
Solution Approach 1:
The measurement device performs data processing and comparison operations autonomously without requiring user intervention to transfer data to external equipment. The device automatically stores measurement results, retrieves reference data, processes the comparison, and presents the results, thereby ensuring thorough data processing while greatly improving operational convenience.
3Adaptability or versatility
If reference data is stored externally on a PC, then data storage flexibility is maintained, but device functionality is limited
Solution Approach 1:
The measurement device is designed with multi-functional capabilities, incorporating not only measurement functions but also reference data storage, retrieval, and automated comparison processing. This universal design allows the device to perform previously separate functions (measurement, data management, and analysis) within a single system, enhancing functionality while maintaining storage flexibility through integrated memory and reference data bases.
