Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent reflecting surfaces (IRS) designed for wireless communication apparatuses are visually non-transparent, compromising aesthetic design and limiting their application scenarios due to their opaque nature, which obstructs the background and compromises the original appearance.
Innovation Solution
Integrate a transparent reflecting surface assembly onto a display panel, comprising a functional layer with reflecting units and a shielding layer, both of which are transparent, connected to a control circuit that can change the electrical load of the reflecting units, enhancing wireless communication performance while maintaining transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional intelligent reflecting surfaces are used, then wireless communication performance is improved, but visual transparency deteriorates
Solution Approach 1:
The patent changes the material parameters of the reflecting surface assembly by using transparent conducting oxide layers instead of traditional metal foils. This allows the surface to maintain electrical conductivity for wireless communication while achieving optical transparency. The control circuit adjusts the electrical load of reflecting units to optimize both communication performance and visual properties.
Solution Approach 2:
The patent employs composite material structures combining transparent conducting oxide layers with transparent substrates. This composite approach integrates the electrical functionality needed for wireless communication with the optical properties required for visibility, creating a multi-functional reflecting surface assembly.
2Illumination intensity
If transparent materials are used for the reflecting surface, then visual appearance is improved, but wireless signal reflection capability deteriorates
Solution Approach 1:
The patent adjusts the electrical parameters of the transparent conducting oxide layers through control circuits that modify the electrical load of individual reflecting units. This dynamic parameter adjustment enables the transparent material to achieve sufficient signal reflection capability when needed while maintaining its transparent appearance during normal operation.
