Solution Overview

Problem

Current telephone switching systems lack effective methods for detecting and preventing illegal use, such as unauthorized international calls, and often require manual intervention to adjust settings, which can lead to impaired usability and increased administrative burdens.

Innovation Solution

A telephone switching system comprising a switchboard and a management terminal that detects illegal events, generates notification emails, and allows for automatic setting changes based on reply emails, enabling administrators to easily regulate operations without manual user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If access from the Internet is restricted too strictly to prevent illegal use, then system security is improved, but usability for legitimate use is impaired

Engineering Contradiction:
Improvesystem securityVSAvoidusability for legitimate use
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by detecting predetermined events (illegal use patterns) and proactively notifying administrators before significant damage occurs. The telephone switchboard automatically detects abnormal access patterns, generates notification emails, and enables pre-configured automatic responses to block illegal calls before they can cause substantial harm, while maintaining open access for legitimate users.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring telephone switchboard operations, detecting illegal use patterns, and automatically adjusting blocking rules based on detected events. The system provides real-time feedback to administrators through email notifications and automatically modifies operation conditions based on detected illegal activities, thereby maintaining security without manually restricting legitimate access.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If manual intervention is required to change settings for regulating operations, then control precision is improved, but administrative burden increases

Engineering Contradiction:
Improvecontrol precisionVSAvoidadministrative burden
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The telephone switchboard performs self-service by automatically detecting predetermined events (illegal use patterns), generating notification emails, and executing pre-configured automatic responses without requiring continuous manual intervention. The system autonomously monitors operations, identifies illegal activities, and implements blocking actions based on predetermined rules, significantly reducing administrative burden while maintaining precise control through automated event detection and response execution.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Administrators perform preliminary actions by pre-configuring operation conditions and automatic responses before illegal events occur. When illegal use is detected, the system automatically executes the pre-set responses, eliminating the need for administrators to manually analyze and respond to each incident in real-time, thereby reducing administrative burden while maintaining precise control over telephone operations.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automatic response is implemented based on detected events, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improveresponse efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements automatic responses through feedback loops where the telephone switchboard monitors operations, detects predetermined illegal events, sends notifications to administrators, and automatically executes pre-configured blocking actions. This automated feedback mechanism significantly improves response efficiency by eliminating manual intervention delays, while the complexity is managed through standardized event detection rules and pre-configured response templates.

Inventive Principle:
Principle #23Feedback

AI summary

A telephone switching system capable of enabling an administrator to easily change the setting when an illegal outgoing call is detected and the illegal outgoing call is regulated is provided. A telephone switchboard includes a detection section for detecting an occurrence of a predetermined event, an e-mail creation section for creating a notification mail in which a content of the detected event is described, and a transmitting section for transmitting the notification mail, and the management terminal includes a receiving section for receiving the notification mail, an e-mail creation section for creating a reply mail corresponding to the notification mail, and a transmitting section for transmitting the reply mail. Further, the telephone switchboard further includes a receiving section for receiving the reply mail, and a setting section for setting an operation condition for a predetermined operation performed by the telephone switchboard based on the reply mail received.
