Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently managing data transmission and communication relay devices, particularly in the context of data transmission via relay devices and access points, where existing technologies do not effectively adapt to varying communication states and security levels, leading to inefficiencies and increased costs.
Innovation Solution
A communication control system and method that employs a communication terminal with multiple relay modes (first, second, and third modes) to adapt to the state of communication with an information management device, selecting the appropriate mode based on factors like memory availability, communication quality, and security levels, thereby optimizing data transmission and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted via relay devices and access points using existing communication systems, then data transmission can be performed, but communication efficiency is reduced and costs increase due to inability to adapt to varying communication states and security levels
Solution Approach 1:
The communication terminal dynamically switches between three relay modes (first mode with immediate transmission, second mode with temporary storage and delayed transmission, third mode with security verification) based on real-time communication state and security level requirements. This dynamic adaptation optimizes communication efficiency while reducing unnecessary costs associated with overly secure or inefficient transmission methods
Solution Approach 2:
The system changes transmission parameters including relay mode selection, data storage duration, and security verification levels based on communication state assessments. By adjusting these parameters dynamically, the system achieves optimal balance between communication efficiency and cost effectiveness
2Adaptability or versatility
If existing communication systems are used without adaptive relay modes, then simple data transmission is possible, but the system cannot adapt to varying communication states and security levels
Solution Approach 1:
The relay function is segmented into three distinct modes (first mode for immediate transmission, second mode for temporary storage, third mode for security-verified transmission). This segmentation allows the system to adapt to different communication states while keeping each mode's logic relatively simple and manageable
Solution Approach 2:
The communication terminal continuously assesses communication state and security level requirements, then provides feedback to select the appropriate relay mode. This feedback mechanism enables automatic adaptation without requiring complex manual configuration or control
3Reliability
If security verification is always performed before data transmission, then security risks are minimized, but communication speed and efficiency are reduced
Solution Approach 1:
Security verification is dynamically applied based on assessed security level requirements. The third mode performs security verification before transmission when high security is needed, while the first mode transmits immediately when security requirements are lower, thus maintaining both security and speed efficiency
Solution Approach 2:
The system changes the security verification parameter based on communication state and required security levels. By adjusting this parameter dynamically, the system achieves optimal balance between security reliability and transmission speed
