Solution Overview

Problem

Conventional office extension systems incur high telephone fees due to long-distance calls, and the cost-saving methods, such as upgrading to network extension systems, are expensive and not widely adopted by companies.

Innovation Solution

A communication method and system that uses a switch device to establish network connections between telephone lines and a cloud server, allowing for cost-effective telephone calls by routing communication requests through a series of switch devices and exchange devices, thereby reducing the need for expensive network extension system upgrades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If companies upgrade to network extension systems to save telephone fees, then telephone cost is reduced, but construction cost becomes very expensive

Engineering Contradiction:
Improvetelephone feeVSAvoidconstruction cost
Core Design Contradiction:
Loss of energyVSEase of manufacture

Solution Approach 1:

The patent segments the communication system into multiple functional components: PBX (private branch exchange) for internal routing, switch devices for connection management, and cloud servers for external communication. This segmentation allows companies to adopt network-based communication without building a complete network extension system, reducing construction costs while maintaining fee savings.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces switch devices and cloud servers as intermediary components between the PBX and external networks. These intermediaries enable network-based communication to be established without requiring companies to build their own complete network extension infrastructure, thus reducing the construction cost barrier while still achieving telephone fee savings.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If companies use conventional office extension systems, then construction cost is low, but telephone fee is high

Engineering Contradiction:
Improveconstruction costVSAvoidtelephone fee
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent creates a universal communication architecture where the PBX can serve dual purposes: traditional telephone routing and network-based communication. The switch devices and cloud servers provide multi-functional services, enabling companies to maintain low construction costs while reducing telephone fees through network-based calling.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of energy

If companies limit the time of telephone calls to save costs, then telephone fee is reduced, but communication efficiency is compromised

Engineering Contradiction:
Improvetelephone feeVSAvoidcommunication efficiency
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent replaces the mechanical/time-based cost control mechanism with a network-based routing mechanism. Instead of limiting call duration to save costs, the system uses switch devices and cloud servers to route calls through network connections that charge lower rates, allowing unlimited or extended communication without compromising efficiency while reducing costs.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed are a communication method and a communication system. The method includes the following steps: a first communication device sends a communication request signal and a second identification code corresponding to a second communication device to a first switch device via a first exchange device by means of telephone connection; the first switch device sends the communication request signal and the second identification code to a second switch device via a cloud server by means of network connection; the second switch device sends the communication request signal to the second communication device via a second exchange device by means of telephone connection; when the second communication device confirms the communication request signal, a communication connection is set up between the first communication device and the second communication device via the first switch device, the cloud server and the second switch device.
