Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional ruler is used for measurement, then the reading process is simple and familiar to users, but the measurement accuracy is low and additional professional tools are required
Solution Approach 1:
The patent combines a conventional ruler with digital measurement components (linear displacement sensor, angular displacement sensor, gravity acceleration sensor, and digital display module) into a single integrated device. This merging allows the ruler to perform both traditional length measurement and professional angle measurement functions, eliminating the need for separate professional angle measuring tools while maintaining the familiar ruler form factor that users already know how to use
2Measurement precision
If a professional angle measuring tool is used, then the measurement accuracy is high, but the operation becomes more complex and time-consuming
Solution Approach 1:
The ruler is designed with multi-functionality, serving both as a traditional length measurement tool and as a professional angle measuring device. The integrated sensors (linear displacement sensor for horizontal movement, angular displacement sensor for rotation, and gravity acceleration sensor for orientation) enable the single device to perform multiple measurement functions, eliminating the need to switch between different specialized tools and simplifying the operational process
3Measurement precision
If digital sensors and display modules are integrated into the ruler, then the reading accuracy and convenience are improved, but the device complexity increases
Solution Approach 1:
The measurement system employs self-service through automatic detection and display. The sensors (linear displacement sensor, angular displacement sensor, gravity acceleration sensor) automatically detect measurement parameters without manual intervention, and the digital display module automatically presents the results. This automation eliminates the need for manual reading and calculation processes, compensating for the increased component complexity with gains in operational simplicity and reading accuracy
