Solution Overview

Problem

The complexity of setting audio signal parameters for various output devices and applications leads to incomplete individualization, resulting in poor sound or speech comprehension, as users face difficulties in optimizing settings across multiple devices and scenarios, and manufacturers incur additional costs in providing comprehensive user interfaces.

Innovation Solution

A system comprising an output device, a data storage, and an administration device that searches for and transfers stored parameter values similar to those set by the user, allowing for automatic optimization of audio signal output across different devices and scenarios, considering user preferences and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If comprehensive parameter settings are provided for each output device and application, then optimal listening experience is achieved, but device complexity and manufacturing costs increase significantly

Engineering Contradiction:

Improveindividualization of audio settingsVSAvoiduser interface complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

A server acts as an intermediary between users and multiple output devices. The server stores user profiles with individualized audio parameters and automatically retrieves and applies appropriate settings based on the output device being used, eliminating the need for complex user interfaces on each device while maintaining comprehensive individualization

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

User profile data is copied and transferred from the server to multiple output devices. Instead of implementing complex setting mechanisms in each device, the system creates copies of optimized parameter sets stored centrally on the server and distributes them to various devices, reducing individual device complexity while preserving full functionality

Inventive Principle:

Principle #26Copying

2Ease of operation

If users manually optimize parameters for each device and application, then optimal sound quality is achieved, but user time and effort increase enormously

Engineering Contradiction:

Improveparameter setting processVSAvoidtime for individualization

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

User profiles with optimized audio parameters are created and stored in advance on the server. When a user accesses any output device, the system automatically retrieves the pre-configured profile and applies the appropriate settings without requiring the user to spend time on manual optimization, thus eliminating time loss while maintaining ease of operation

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If simplified parameter settings are implemented to reduce complexity, then manufacturing costs decrease, but listening experience and speech comprehension deteriorate

Engineering Contradiction:

Improveimplementation costVSAvoidsound quality

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The server intermediary provides comprehensive audio processing capabilities that would be too complex for individual devices. It implements advanced signal processing algorithms and stores detailed user profiles, then transmits processed audio signals to simplified output devices, enabling high-quality sound reproduction without requiring complex manufacturing in each device

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces mechanical/physical complexity in output devices with digital/software-based solutions on the server. Instead of implementing complex hardware circuits and user interfaces in each device, the system uses software-based audio processing and parameter management on the server, reducing manufacturing costs while maintaining or improving sound quality through flexible digital signal processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

What is described is a system for outputting audio signals having a first output device for outputting audio signals having predeterminable parameter values of a first set of settable parameters, a data storage for storing parameter values, and an administration device. Thus, the administration device accesses the data storage and searches for stored parameter values for a set of parameters which is equal or similar to the first set of parameters. In addition, in case of having found stored parameter values, the administration device transfers the parameter values and/or parameter values determined therefrom to the first output device.
