Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current telephone systems face difficulties in quickly and efficiently changing installation status during telephone exchanges, requiring manual intervention to update management tables and MAC addresses of IP telephones.

Innovation Solution

A telephone system that includes a management table managing telephone identification information, accommodation position information, and extension numbers, allowing for automatic identification and rewriting of data during exchanges by searching based on provided identification and accommodation position information, enabling automatic data transfer without manual changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual changes are made to update management tables during telephone exchange, then telephone exchange can be performed, but the process requires significant time and effort

Engineering Contradiction:

Improvetelephone exchange speedVSAvoidtime required for manual updates

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The exchange automatically performs telephone exchange operations by detecting changes in telephone identification information and accommodation position information from registration requests, eliminating the need for manual intervention in updating management tables. The system serves itself by autonomously completing the exchange process based on received registration data.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The exchange updates the management table in advance by processing registration requests that contain new telephone identification information and accommodation position information before the actual telephone exchange is completed. This preliminary update ensures that when the exchange occurs, all necessary data is already prepared and configured.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If manual intervention is used to update management tables, then telephone exchange can be completed, but the operation becomes complex and labor-intensive

Engineering Contradiction:

Improveease of telephone exchangeVSAvoidcomplexity of management table updates

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The exchange automatically detects when telephone identification information or accommodation position information changes in the management table by processing registration requests. The system autonomously determines when an exchange has occurred and updates the necessary data without requiring manual intervention, thereby simplifying the operation while managing complexity internally.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The exchange monitors registration requests for changes in telephone identification information and accommodation position information, using this feedback to automatically detect telephone exchanges and update the management table accordingly. This continuous monitoring and automatic response mechanism simplifies operation by eliminating manual steps.

Inventive Principle:

Principle #23Feedback

3Extent of automation

If automatic identification and data rewriting are implemented, then telephone exchange becomes quick and automated, but the system complexity increases

Engineering Contradiction:

Improveautomation of telephone exchangeVSAvoidcomplexity of exchange system

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The exchange automatically identifies telephone exchanges by detecting changes in telephone identification information and accommodation position information from registration requests. The system autonomously rewrites management table data without external intervention, achieving high automation while containing complexity within the exchange's internal processing logic.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The exchange performs multiple functions through a single automated process: it detects telephone exchanges, updates telephone identification information, updates accommodation position information, and rewrites management tables all in one integrated operation. This multi-functionality achieves comprehensive automation without proportionally increasing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system includes: a first telephone; a relay that manages first accommodation position information of the first telephone; and an exchange that includes a management table that manages second telephone identification information, second accommodation position information of a second telephone connected to the relay, and an extension number of each of a plurality of the second telephones, receives first telephone identification information and the first accommodation position information, when the first telephone identification information does not match with any one of the second telephone identification information registered, and the first accommodation position information matches with one of the second accommodation position information in the management table, changes second telephone identification information corresponding to the matched second accommodation position information to the first telephone identification information, and uses an extension number corresponding to the matched second accommodation position information as an extension number of the first telephone.
