Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Directional communication media, while offering large capacity and low delay, are susceptible to shielding and disturbance due to their directionality, and existing technologies fail to provide robustness in network configurations that adapt to node subscription and position changes.
Innovation Solution
A communication system comprising multiple communication apparatuses and a control apparatus that manage and control connections, enabling scanning for connection candidates, establishing connections, and reestablishing broken connections to maintain a stable meshed network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If directional communication media are used to achieve large capacity and low delay, then communication capacity and speed are improved, but the network becomes susceptible to shielding and disturbance due to directionality
Solution Approach 1:
The patent implements dynamic connection management where the control apparatus continuously monitors connection status and automatically reestablishes broken connections. The system adapts to changing network conditions by dynamically adjusting connection routes and reconfiguring the meshed network topology when directional communication links are blocked or disturbed, thereby maintaining network robustness while utilizing high-capacity directional communication media.
2Speed
If directional communication media are used, then communication speed is improved, but adaptability to node position changes and shielding conditions deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the control apparatus monitors connection status, detects broken links due to shielding or node movement, and automatically triggers reconnection procedures. The system receives feedback about network conditions and adapts by reestablishing connections through alternative paths in the meshed network, thereby maintaining adaptability to position changes while utilizing high-speed directional communication.
Solution Approach 2:
The patent changes the operational parameters of the communication system by implementing automatic connection management and reconfiguration capabilities. When directional communication links are blocked or nodes move, the system modifies connection parameters, switches to alternative routes, and adjusts network topology dynamically, enabling adaptability to changing conditions while maintaining high communication speeds through directional media.
3Device complexity
If manual connection management is used, then device complexity is reduced, but network stability and automatic recovery from connection breaks deteriorates
Solution Approach 1:
The patent implements self-service automation where the control apparatus autonomously monitors connection status, detects broken links, and automatically reestablishes connections without requiring manual intervention. The system performs self-diagnosis and self-repair by automatically configuring alternative routes in the meshed network, thereby maintaining high network stability while keeping device complexity manageable through automated rather than manual processes.
