1Object-affected harmful factors
If radar data analysis is used to determine component composition, then non-destructive assessment is enabled, but measurement precision is limited compared to destructive methods
Solution Approach 1:
The patent replaces destructive mechanical drilling and physical inspection with electromagnetic radar wave-based detection. The radar sensor emits electromagnetic signals that penetrate building components and reflect off internal structures, allowing composition determination without mechanical contact or damage to the component.
Solution Approach 2:
The patent analyzes changes in radar signal parameters (reflection coefficients, signal strength, time of flight) to infer compositional information. By measuring how electromagnetic waves interact with different materials and layer structures, the system determines component composition through parameter analysis rather than direct physical examination.
2Device complexity
If simple object pinpointing is used, then device complexity is reduced, but information completeness about component structure is insufficient
Solution Approach 1:
The patent extends the functionality of the radar locating device beyond simple object detection to include component composition analysis. The same radar sensor and signal processing system that locate objects are also used to analyze reflection patterns that reveal layer structures, material types, and thickness measurements, enabling multiple functions from a single device.
Solution Approach 2:
The patent uses the reflected radar signals as feedback to infer compositional information. By analyzing the characteristics of reflected waves (strength, timing, pattern), the system continuously refines its understanding of the component structure, transforming the feedback from simple object detection data into detailed compositional information.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables non-destructive determination of building component structures, facilitating accurate assessment and identification of potential issues, enhancing safety and reducing repair costs.
Implementation Method 1
The sensor is, in particular, a radar sensor. The radar sensor can be used by emitting electromagnetic waves and receiving the reflected waves.
Implementation Method 2
If an object is located near the sensor, a portion of the emitted waves is reflected by the object and directed back to the sensor.
Implementation Method 3
The sensor then preferably detects the reflected waves and can determine the positions and sizes of objects based on the travel time and strength of the reflected signals.
Implementation Method 4
determining a permittivity and thickness of at least one layer of the component based on the detected at least one reflection
