Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in collective housing, such as apartment buildings, face challenges in effectively transmitting millimeter waves due to high attenuation through window glass, leading to inadequate signal strength and coverage within rooms.
Innovation Solution
A communication system utilizing a radio wave focusing plate installed on a veranda to focus millimeter waves from a base station onto the boundary between the exterior and interior, enhancing signal strength and coverage by directing the waves through a metamaterial or dielectric lens to a focal point within the room.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If millimeter waves are transmitted through window glass in collective housing, then communication coverage can be provided, but signal strength is severely attenuated and inadequate
Solution Approach 1:
A radio wave focusing plate is introduced as an intermediary component between the base station and the terminal apparatus. This focusing plate receives millimeter waves from the base station, focuses them through optical concentration, and directs the concentrated waves through the window glass into the room, thereby mediating the harmful attenuation effect of the glass
Solution Approach 2:
The system changes the directional parameters and concentration parameters of radio waves. By adjusting the focusing plate's orientation and using optical concentration, the radio wave density and directionality are modified to penetrate the window glass more effectively, transforming the propagation parameters to overcome the glass barrier
2Speed
If wired optical line connections are used for high-speed communication, then communication speed is improved, but installation complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical wired optical line connection system with a wireless radio wave transmission system. By using electromagnetic waves and optical focusing instead of physical cable infrastructure, the system achieves high-speed communication while eliminating the complexity of wired installation
3Reliability
If fixed wireless access utilizing public LTE is used, then communication coverage is provided, but signal attenuation through building materials reduces effectiveness
Solution Approach 1:
Instead of attempting uniform signal distribution, the system applies local quality enhancement by concentrating radio waves at specific focal points within the room. The focusing plate creates localized high-density wave regions where terminal apparatus are likely to be positioned, providing effective communication in those specific locations while acknowledging attenuation in other areas
