Solution Overview
Problem
Current detection devices for electromagnetic signals face challenges in increasing dynamic range, leading to overloading of receiver regions when detecting signals with varying intensities, especially in applications with strong background noise and objects of differing reflectivities.
Innovation Solution
Incorporating a diffraction element that splits incident electromagnetic signals into multiple components, each directed to separate receiver regions, preventing overloading and allowing for a broader range of detectable signal intensities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single receiver region is used to detect electromagnetic signals, then the device structure is simple, but the receiver gets overloaded when detecting strong signals and cannot detect weak signals effectively
Solution Approach 1:
The receiver is divided into multiple receiver regions (first receiver region and second receiver region) that are spatially separated. The diffraction element splits the incident electromagnetic signal into multiple components that are directed to different receiver regions, allowing simultaneous detection of strong and weak signals without mutual interference or overload.
2Reliability
If the receiver detects all signal intensities without division, then the device structure is simple, but the dynamic range of detection is limited
Solution Approach 1:
The signal detection process is segmented into multiple parallel paths. Strong signal components are directed to one receiver region while weak signal components are directed to another receiver region, enabling the system to simultaneously detect signals across a wide dynamic range without saturation or loss of sensitivity.
Solution Approach 2:
A diffraction element is introduced as an intermediary component between the incident signal and the receiver regions. This diffraction element splits the electromagnetic signal into multiple components with different intensities and directs them to appropriate receiver regions, effectively expanding the detectable dynamic range.
3Productivity
If strong echo signals are detected directly, then the detection process is simple, but the receiver regions become overloaded and cannot detect weak signals
Solution Approach 1:
The receiver is segmented into multiple regions that can independently process different signal intensities. By directing strong echo signal components to one receiver region and weak components to another, the system maintains high detection capability across the full range of signal intensities without overload or accuracy loss.
Solution Approach 2:
Different receiver regions are optimized for detecting different signal intensities. The first receiver region is suited for strong signals while the second receiver region is suited for weak signals, allowing each region to operate in its optimal performance range and maintain high detection accuracy for all signal levels.
