Adjustable Reflective Panel Fence for Electromagnetic Wave Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic wave reflecting devices face challenges in easily adjusting the position or angle of the reflective panel with respect to incident electromagnetic waves, particularly in environments with restricted space or frequent layout changes.
Innovation Solution
The electromagnetic wave reflecting device includes a reflective panel, a frame to hold the panel, and a leg portion that supports the frame. A movable part allows for easy adjustment of the panel's position or angle, with the leg portion extending in a direction intersecting the reflective surface, providing stability and ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specular reflector with a large area is used to improve reflection efficiency, then the gain and propagation environment are improved, but the device becomes difficult to move and adjust due to its size and weight
Solution Approach 1:
The reflective panel is divided into multiple smaller panels that can be independently adjusted. Each panel is held by a frame and supported by a leg portion, allowing individual positioning and angle adjustment without moving the entire large structure. This segmentation enables easy reconfiguration while maintaining overall reflection efficiency.
Solution Approach 2:
The leg portion is designed to be movable relative to the frame, enabling dynamic adjustment of the reflective panel's position and angle. The movable part allows the panel to be repositioned according to different base station locations and reflection requirements, transforming a static large reflector into a dynamically adjustable system.
2Adaptability or versatility
If a metasurface reflector is used to control reflection angle, then the reflection direction can be precisely controlled, but the reflector requires microfabrication and has size restrictions limiting its area
Solution Approach 1:
Instead of using a single large metasurface panel requiring microfabrication, the system uses multiple smaller conventional reflective panels. Each panel can be manufactured separately with standard techniques, avoiding the complexity of large-area microfabrication while achieving similar reflection control through geometric arrangement.
Solution Approach 2:
The patent transitions from controlling reflection through surface geometry (metasurface approach) to controlling reflection through spatial arrangement and panel orientation. By adjusting the position and angle of multiple panels in three-dimensional space, the system achieves reflection angle control without requiring sub-wavelength surface structures.
3Adaptability or versatility
If the installation location or layout is frequently changed, then adaptability to different environments is improved, but the reflector itself needs to be moved which is difficult for large reflectors
Solution Approach 1:
The reflective system is segmented into multiple smaller panels that can be independently moved and repositioned. When relocation is needed, individual panels or small groups can be moved separately rather than moving a single large reflector, significantly improving movability and installation flexibility.
Solution Approach 2:
The movable leg portion enables dynamic repositioning of each reflective panel. This dynamic capability allows the system to be quickly reconfigured for different installation locations and layouts, providing high adaptability without the logistical challenges of moving large fixed reflectors.
