Radio Wave Sensor Alignment from Outside the Target Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio wave sensors face challenges in accurately adjusting their radiation direction, especially when installation requires entering difficult-to-access target areas, such as roads with vehicle traffic, necessitating the closure of the area for reference object placement.
Innovation Solution
A method and device for installing a radio wave sensor that utilizes a reference object positioned outside the target area, allowing for adjustment of the radiation direction without requiring workers to enter the target area, using a sighting device and controller to align the radiation direction with a reference object, and adjusting the elevation angle based on reflection power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a reference object is installed inside the target area for accurate radiation direction adjustment, then the adjustment precision is improved, but the installation complexity and safety risks increase due to the need to enter difficult-to-access areas like roads with vehicle traffic
Solution Approach 1:
The patent introduces a reference object installed outside the target area as an intermediary for adjustment. This reference object serves as a mediator that allows workers to adjust the radiation direction from a safe, accessible location without needing to enter the dangerous target area, thereby resolving the contradiction between adjustment precision and installation complexity/safety
Solution Approach 2:
The reference object is installed in advance outside the target area before the actual radiation direction adjustment takes place. This preliminary action prepares the adjustment reference in a safe location, eliminating the need for workers to enter the target area during the adjustment process, thus reducing installation complexity and safety risks while maintaining adjustment precision
2Measurement precision
If the target area is closed for reference object installation, then the adjustment accuracy is improved, but the loss of time and productivity increase due to road closure
Solution Approach 1:
By using a reference object installed outside the target area as an intermediary, the patent eliminates the need to close the target area for adjustment operations. Workers can perform accurate radiation direction adjustment from a safe, accessible location, thereby maintaining adjustment accuracy while avoiding the productivity loss associated with road closure
Solution Approach 2:
The reference object is preliminarily installed outside the target area before adjustment operations begin. This preliminary positioning allows subsequent adjustment work to be performed without closing the target area, thus maintaining both adjustment accuracy and installation efficiency by avoiding road closure
3Measurement precision
If workers enter the target area for reference object placement, then the radiation direction can be accurately adjusted, but the safety risks and operational difficulty increase
Solution Approach 1:
The patent uses a reference object installed outside the target area as an intermediary tool. This intermediary allows workers to perform radiation direction adjustment from a safe, accessible location without entering the dangerous target area, thereby achieving both accurate adjustment and ease of operation
Solution Approach 2:
Instead of installing the reference object inside the target area (the conventional approach), the patent inverts the approach by installing it outside the target area. This inversion allows workers to operate from a safe location while still achieving accurate radiation direction adjustment, thus improving both safety and operational ease
