Engineering Contradiction Analysis
1Measurement precision
If traditional dimensioning methods are used in online commerce, then measurement accuracy is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces complex mechanical measurement systems with an electronic handheld device equipped with acceleration sensors. The device uses sensor data processing and integration algorithms to calculate path lengths, substituting traditional mechanical calipers or tape measures with electronic sensing and computational methods, thereby maintaining measurement accuracy while reducing device complexity
Solution Approach 2:
The handheld device performs self-measurement by using its own acceleration sensors to track its movement along the path. The device independently calculates velocity and position by integrating sensor data, eliminating the need for external measurement equipment or complex setup procedures, thus improving ease of operation without sacrificing measurement precision
2Measurement precision
If traditional dimensioning methods are used in online commerce, then measurement accuracy is improved, but ease of operation worsens
Solution Approach 1:
The handheld device autonomously performs measurements by using its built-in acceleration sensors to track its own movement. The device automatically integrates sensor data to calculate velocity and position, and computes path lengths without requiring user intervention in the calculation process, making the operation simple and accessible to average users while maintaining high measurement accuracy
Solution Approach 2:
The patent replaces manual measurement techniques with electronic sensing and automated computation. The acceleration sensors continuously track device movement, and integrated algorithms automatically calculate path lengths, eliminating the need for users to manually read scales or perform calculations, thereby significantly improving ease of operation while preserving measurement precision
3Ease of operation
If acceleration sensor integration is used to measure path length, then ease of operation is improved, but measurement precision worsens
Solution Approach 1:
The system continuously monitors acceleration sensor data and uses integration algorithms to calculate velocity and position in real-time. By continuously processing sensor feedback and updating position calculations, the system compensates for accumulated errors and maintains measurement accuracy throughout the measurement process, ensuring reliable results even with the simplicity of the operation
Solution Approach 2:
The patent employs multiple integration steps (acceleration to velocity, velocity to position) and processes data over multiple time intervals to improve measurement accuracy. By performing excessive computational steps and processing more data than the minimum required, the system achieves higher precision measurements while keeping the user interface simple and easy to operate
