Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems fail to establish direct and reliable communication between multiple devices within shielded rooms or across multiple closed spaces, particularly in environments like flying objects where electromagnetic wave reflectors hinder communication and require detouring communication lines around obstacles like fuel tanks, exposing them to high temperatures and external noise.
Innovation Solution
A wireless communication system utilizing a leaky transmission line with leakage parts and antennas within shielded rooms, allowing direct two-way communication without an access point, and integrating the leaky transmission line and power supply line within the flying object's structure to penetrate through barrier walls and maintain communication across internal spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired communication line is provided between devices at front and rear of a flying object, then communication can be established, but the communication line must detour around components like fuel tank and engine, exposing it to high temperatures and external electromagnetic noises
Solution Approach 1:
The patent transitions from wired communication (physical dimension) to wireless communication (electromagnetic wave dimension). By using wireless stations that transmit and receive electromagnetic waves, the communication system eliminates the need for physical communication lines that would be exposed to harmful environmental factors, while maintaining reliable communication between devices on the flying object.
Solution Approach 2:
The patent introduces wireless stations as intermediary devices that facilitate communication between front and rear devices without direct physical connection. These wireless stations transmit signals through electromagnetic waves, acting as mediators that eliminate the need for exposed communication lines while enabling reliable data transmission across the flying object.
2Reliability
If wireless communication is performed in shield rooms with electromagnetic wave reflectors, then communication can be attempted, but the reflectors block and hinder the wireless communication signals
Solution Approach 1:
The patent converts the harmful effect of electromagnetic wave reflection into a beneficial one by strategically placing wireless stations and reflectors. Instead of allowing reflections to block communication, the system uses controlled reflections to redirect and distribute electromagnetic waves throughout the shield room, ensuring coverage in areas that would otherwise be dead zones while maintaining communication reliability.
Solution Approach 2:
The patent applies different properties to different parts of the shield room by strategically positioning wireless stations and electromagnetic wave reflectors in specific locations. Each wireless station is placed to cover specific zones, and reflectors are positioned to redirect waves to particular areas, creating localized communication zones that overcome the blocking effects of the shield room structure.
3Reliability
If access points are used to enable wireless communication in shield rooms, then communication can be facilitated, but the system complexity increases and direct two-way communication between devices is not achieved
Solution Approach 1:
The patent enables devices to perform wireless communication directly with each other without requiring external access points or base units. Each wireless station independently transmits and receives signals, allowing devices to self-communicate peer-to-peer. This eliminates the need for complex centralized infrastructure while maintaining reliable communication capability within shield rooms.
