Engineering Contradiction Analysis
1Productivity
If multiple data conversion and transfer steps are used in the standard measurement system, then comprehensive data collection is achieved, but the process becomes time-consuming and inefficient
Solution Approach 1:
The patent replaces manual mechanical operations (operator moving with measurement device, manual data transfer) with automated electronic systems. Sensors continuously acquire data and transfer it automatically to the additional computer via wireless communication, eliminating the need for manual data collection and transfer operations.
Solution Approach 2:
The measurement device is pre-configured with multiple sensors (microphone, thermocouple, pressure sensor, accelerometers) before the test flight. This preliminary setup enables simultaneous acquisition of multiple parameters without requiring sequential manual measurement operations during the flight.
2Measurement precision
If manual measurement and data transfer operations are performed, then data accuracy can be maintained, but the complexity of the system increases
Solution Approach 1:
The patent merges multiple measurement functions (acoustic, thermal, pressure, vibration) into a single integrated measurement device. This consolidation maintains comprehensive data collection capabilities while reducing system complexity compared to using separate manual measurement tools for each parameter.
Solution Approach 2:
The measurement device performs self-service by automatically acquiring, processing, and transmitting data without requiring continuous manual intervention. The device autonomously manages the measurement process, reducing the operational complexity for the operator while maintaining data accuracy.
