Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional VoIP call services limit users to selecting pre-provided sound sources for ringtone and ringback tones, restricting the use of personalized or directly edited sound sources.

Innovation Solution

A method and system that allows users to select and play back directly edited sound sources as ringtone or ringback tones by storing them on a terminal or web server, enabling streaming playback or stopping playback in response to a VoIP server reply during a call setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users select from pre-provided sound sources, then the system operation is simple, but the user customization capability is limited

Engineering Contradiction:

Improveuser customization capabilityVSAvoidsystem operation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system allows users to edit and prepare their custom sound sources in advance through a user terminal before the actual call. The edited sound source is stored and ready for use, so that during the call, the system only needs to retrieve and play the pre-prepared custom sound source, maintaining simple real-time operation while achieving high customization capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A server acts as an intermediary between the user terminal and the VoIP call system. The user edits sound sources on their terminal, the server stores and manages these custom sound sources, and then provides them to the call system when needed. This intermediary architecture separates the complex customization process from the simple call operation, allowing users to customize without complicating the real-time call operation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If pre-editing sound sources is required, then sound source quality is improved, but the service response time is increased

Engineering Contradiction:

Improvesound source qualityVSAvoidservice response time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

Users edit and prepare their custom sound sources in advance through a user terminal before the actual call. The edited sound source is stored on the server or user device, so that during the call, the system only needs to retrieve and play the pre-prepared custom sound source, eliminating real-time processing delays while maintaining high sound quality

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the user's custom sound source and stores it on the server. During the call, the server retrieves and plays this pre-stored copy instead of processing the original file in real-time. This copying mechanism allows the system to benefit from pre-editing quality while avoiding the time penalty of real-time processing during the call

Inventive Principle:

Principle #26Copying
