Solution Overview

Problem

The testing process for electronic devices in IP phone systems is complex and time-consuming, requiring multiple peripheral devices to be connected and disconnected from the IP phone host to generate various power commands, making it difficult to determine if the device correctly controls DVI and USB ports.

Innovation Solution

A testing apparatus comprising a power supply, a power generating jig, and an IP phone simulator is used to connect to the electronic device, providing different power commands via a 1-wire signal line to determine if the device correctly controls its signal ports, eliminating the need for an IP phone host and simplifying the testing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple peripheral devices are connected and disconnected from the IP phone host to generate various power commands, then the testing process can determine if the device correctly controls ports, but the testing process becomes complex and time-consuming

Engineering Contradiction:
Improvetesting accuracyVSAvoidtesting process complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts the IP phone host from the testing system and replaces it with a dedicated testing apparatus. The testing apparatus includes a power supply unit, control unit, and interface unit that can independently generate and transmit power commands to the electronic device being tested, eliminating the need for an IP phone host and multiple peripheral devices in the testing process

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a testing apparatus as an intermediary between the power supply and the electronic device. The testing apparatus includes a control unit that generates power commands and transmits them through the 1-wire interface, serving as a mediator that simplifies the testing process while maintaining testing accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple peripheral devices are connected and disconnected from the IP phone host to generate various power commands, then the testing process can determine if the device correctly controls ports, but the testing process becomes time-consuming

Engineering Contradiction:
Improvetesting accuracyVSAvoidtesting time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-configuring the testing apparatus with a library of power commands that correspond to different power consumption scenarios. The control unit can directly transmit these pre-prepared power commands to the electronic device without requiring manual connection and disconnection of peripheral devices, significantly reducing testing time while maintaining comprehensive testing coverage

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent ensures continuity of useful action by enabling the testing apparatus to continuously transmit power commands through the 1-wire interface without interruption. The control unit can sequentially send multiple power commands to test different scenarios without requiring physical reconfiguration, maintaining continuous testing flow and reducing overall testing time

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If an IP phone host is used for testing electronic devices, then the device can be tested in a real system environment, but the testing process requires complex setup with multiple peripheral devices

Engineering Contradiction:
Improvetesting environment realismVSAvoidtesting setup complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the testing function into independent modules within the testing apparatus. The power supply unit, control unit, and interface unit are separated into distinct functional blocks, allowing the testing apparatus to be configured independently without requiring a complete IP phone host system. This modular approach maintains testing realism while reducing overall setup complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a simplified copy of the IP phone host's power command generation capability. The testing apparatus includes a control unit that replicates the essential function of generating and transmitting power commands through the 1-wire interface, providing a functional copy that maintains testing validity without requiring the actual IP phone host and its complex peripheral connections

Inventive Principle:
Principle #26Copying
