Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately and efficiently measure the structural parameters of corrugated pipes, particularly in terms of layer thicknesses and structure widths, especially when dealing with pipes of varying diameters and structure widths.
Innovation Solution
A THz measuring device employing a THz transceiver unit with an upstream lens, utilizing a frequency modulated continuous wave (FMCW) radar, emits a convergent THz beam with a focal length to measuring distance ratio of at least 60% and a convergence angle of 1° to 5°, allowing for precise measurement of corrugated pipes without the need for active focusing or adjustment of the measuring distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional measuring device is used, then it can measure corrugated pipes, but it requires active focusing or adjustment of measuring distance for pipes of different diameters
Solution Approach 1:
The patent applies parameter changes by using a THz transceiver with a fixed focal length that is specifically chosen to be at least 60% of the measuring distance. This parameter relationship creates a beam geometry that naturally adapts to different pipe diameters without requiring active focusing mechanisms. The beam's convergence characteristics, determined by the focal length to measuring distance ratio, automatically adjust the measurement capability across various pipe sizes.
2Measurement precision
If a narrow beam is used to resolve waves and valleys, then measurement precision improves, but the device complexity increases due to focusing requirements
Solution Approach 1:
The patent achieves a narrow beam for resolving waves and valleys by optimizing the focal length parameter relative to the measuring distance. By setting the focal length to be at least 60% of the measuring distance, the system creates a beam geometry that naturally converges to provide the necessary spatial resolution. This eliminates the need for complex active focusing mechanisms while maintaining the ability to clearly separate and detect adjacent waves and valleys on the corrugated pipe surface.
3Measurement precision
If multiple transceiver units are used to cover different areas, then measurement completeness improves, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single transceiver unit that can measure corrugated pipes of various diameters and structures. The transceiver is equipped with a lens having a focal length that is at least 60% of the measuring distance, creating a beam geometry that adapts to different measurement scenarios. This universal design eliminates the need for multiple specialized transceiver units, reducing system complexity while maintaining measurement completeness across different pipe types.
