Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If discrete point measurements are taken at various locations along the beam at discrete times, then rigidity distribution can be measured, but the measurement process becomes time-consuming and prone to human errors
Solution Approach 1:
The sensor unit continuously moves along the beam to perform measurements at multiple locations without interruption, eliminating the need to reset and reposition between discrete measurement points. This continuous scanning approach maintains measurement accuracy while dramatically reducing total measurement time.
Solution Approach 2:
The measurement system transitions from static discrete-point measurements to dynamic continuous scanning. The sensor unit is designed to move dynamically along the beam, allowing rapid data collection at multiple locations in sequence, thereby reducing measurement time while maintaining precision through automated positioning and data recording.
2Measurement precision
If discrete point measurements are taken at various locations along the beam, then rigidity distribution can be determined, but the set-up steps become complex and prone to human errors
Solution Approach 1:
The sensor unit is designed as a multi-functional device that simultaneously performs positioning, curvature measurement, and data recording. This universal design consolidates multiple separate setup steps into a single integrated unit, reducing complexity while maintaining measurement precision through coordinated operation of all components.
Solution Approach 2:
The measurement system is designed to automatically position the sensor unit and record measurements without requiring manual intervention for each discrete point. The automated scanning and data collection processes eliminate human error in setup and measurement, while the system self-calibrates and self-documents the rigidity distribution along the beam.
3Loss of information
If multiple discrete measurements are taken along the beam, then complete rigidity distribution data can be obtained, but the process requires frequent repositioning and setup adjustments
Solution Approach 1:
The sensor unit performs continuous measurement along the entire length of the beam in a single scanning operation, eliminating the need to stop, reposition, and re-setup between measurement locations. This ensures complete rigidity distribution data is captured while greatly simplifying the operational process.
Solution Approach 2:
The measurement system employs dynamic scanning where the sensor unit moves continuously along the beam, automatically capturing data at all necessary locations without manual repositioning. This dynamic approach maintains complete data coverage while making the measurement process much simpler and more operator-friendly.
