Solution Overview

Problem

Existing mixing technologies require users to pause gameplay and use a mouse to adjust sound volumes and settings, disrupting the gaming experience and causing discomfort for viewers.

Innovation Solution

A mixing device with intuitive physical knobs and LEDs that allow users to adjust sound settings directly on the device, enabling volume and acoustic effect changes without interrupting gameplay or requiring a mouse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users adjust sound settings using application software with mouse operations, then sound setting precision is improved, but operation complexity and interruption of gameplay increase

Engineering Contradiction:
Improvesound setting precisionVSAvoidoperation simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the mechanical mouse operation system with a direct physical control system. The mixing device uses physical knobs that directly adjust sound parameters without requiring mouse operations or screen interactions. This substitution eliminates the need for complex graphical interface operations while maintaining precise sound control through tactile feedback and direct mechanical adjustment.

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

Solution Approach 2:

The patent introduces a physical mixing device as an intermediary between the user and the sound system. This intermediary device with physical knobs and displays serves as a mediator that translates user intentions directly into sound parameter adjustments without requiring interaction with the application software interface, thereby simplifying operations while maintaining precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If users adjust sound settings during gameplay through application interface, then sound setting flexibility is improved, but gameplay continuity deteriorates

Engineering Contradiction:
Improvesound setting flexibilityVSAvoidgameplay interruption time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by providing all sound adjustment controls directly on the mixing device itself, rather than requiring users to switch to an application interface. The physical knobs and immediate feedback mechanisms allow users to make sound adjustments without pausing gameplay or navigating away from the game screen, thus maintaining gameplay continuity while preserving sound setting flexibility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mixing device serves itself by having all necessary sound control functions integrated into the device. The physical knobs, displays, and control mechanisms are self-contained, allowing users to adjust sound settings independently without needing to interact with the application software or pause the game. This self-service capability eliminates gameplay interruptions while maintaining full sound adjustment flexibility.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If physical controls are added to the mixing device, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improvecontrol intuitivenessVSAvoiddevice structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the mixing device into distinct functional modules, each with its own physical controls and displays. The device is segmented into sections for different sound parameters (volume, bass, treble, etc.), with dedicated knobs and indicators for each. This modular segmentation makes the device easier to operate by allowing users to focus on individual controls while managing the overall complexity through organized functional separation.

Inventive Principle:
Principle #1Segmentation

AI summary

A mixing device is provided. The mixing device includes: an input unit, inputting sounds; multiple output units, outputting the sounds; a sound setting operator, setting a sound setting value that is a setting value relating to the sounds; a selection operator, selecting the output unit of a target for setting the sound setting value; a setting value acquisition means, acquiring the sound setting value set by the sound setting operator with respect to the output unit selected by the selection operator; and a mixing means, for each of the output units, mixing the sounds input at the input unit based on the sound setting value corresponding to the output unit and being the sound setting value acquired by the setting value acquisition means.
