Solution Overview

Problem

Existing file transmission systems face challenges in converting audiovisual or text files between different electronic devices due to inconsistent coding formats, leading to resource-intensive codec conversions that are not feasible for devices with limited operational capability or storage space, such as mobile phones.

Innovation Solution

A file conversion system comprising a receiving module, conversion module, database module, and transmission module that records the format profile of the receiving end and converts files to a supported format before transmission, allowing efficient file sharing across devices with varying capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If codec conversion is performed to enable file compatibility across different electronic devices, then file adaptability is improved, but system resource consumption increases

Engineering Contradiction:

Improvefile compatibilityVSAvoidsystem resource consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by performing codec conversion at the file providing end before transmission, rather than at the receiving end. The conversion module converts the file format in advance based on the receiving device's capabilities, so that the converted file can be directly played without requiring additional system resources at the receiving device.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If codec conversion is performed on devices with limited operational capability, then file format compatibility is improved, but device performance deteriorates

Engineering Contradiction:

Improveformat compatibilityVSAvoiddevice performance

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent moves the conversion operation to the file providing end, which has sufficient processing capability. The conversion is completed before transmission, so devices with limited operational capability only need to receive and play the already-converted file, avoiding performance deterioration.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If file conversion is performed at the receiving end, then format compatibility is improved, but storage space requirements increase

Engineering Contradiction:

Improveformat supportVSAvoidstorage space

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent performs conversion at the file providing end before transmission, so the receiving device only needs to store the final converted file in its supported format. There is no need to store multiple version copies of the same file in different formats, thus reducing storage space requirements at the receiving end.

Inventive Principle:

Principle #10Preliminary action

AI summary

A file conversion system is capable of transmitting via a network a file provided by a file providing end in a format supported by a file receiving end to the file receiving end. The file conversion system includes a receiving module for receiving the file provided by the file providing end; a conversion module for converting the format of the file provided by the file providing end into a format supported by the file receiving end; a database module for recording a profile of the file receiving end, with the profile including the format supported by the file receiving end; and a transmission module for transmitting the file to the file receiving end via the network. If the format of the file is not supported by the file receiving end, the conversion module may, in accordance with the profile of the file receiving end, convert the format of the file into the format supported by the file receiving end so as to allow the transmission module to transmit the file to the file receiving end.
