Portable Terminal Automatic IP Setting via Cable Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable communication terminal devices frequently need to reset their IP addresses when moved, as they lack automatic network address setting capabilities, especially when not using DHCP servers due to security concerns.
Innovation Solution
A portable communication terminal apparatus connected to a router via a cable, equipped with a detector to read identifying information, such as RFID tags or measure cable length, and a storage system to store IP addresses, automatically sets a network IP address based on detected cable information, ensuring seamless internet connectivity across different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If DHCP server is used for automatic IP address setting, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent introduces a cable with embedded identification information as an intermediary between the network and the terminal device. This cable acts as a trusted mediator that carries authentication data, allowing the terminal to obtain IP address information automatically without relying on a DHCP server, thus resolving the security concern while maintaining ease of operation
Solution Approach 2:
The identification information is pre-stored in the cable before connection. By performing the authentication preparation in advance (embedding ID info in cable), the system eliminates the need for real-time DHCP server communication, providing automatic IP assignment while enhancing security through pre-established trust
2Reliability
If manual IP address setting is used, then security is improved, but ease of operation is worsened
Solution Approach 1:
The terminal device automatically performs IP address configuration by reading identification information from the connected cable itself. The system serves itself by extracting network configuration data from the cable's embedded information, eliminating manual setting requirements while maintaining security through the cable's inherent authentication mechanism
3Adaptability or versatility
If IP address is reset when moving, then adaptability is improved, but loss of time is worsened
Solution Approach 1:
The terminal device automatically reconfigures its IP address by reading identification information from the cable at each new location. This self-service mechanism eliminates manual intervention and reduces reconfiguration time, allowing rapid adaptation to different network environments while maintaining security through automatic authentication via the cable's embedded data
