Solution Overview

Problem

Existing voice-based devices struggle to adjust output volume dynamically in response to user voice inputs, leading to potential surprises from loud outputs or inadequate hearing from soft outputs, requiring manual adjustments.

Innovation Solution

A user command processing system that adjusts output volume based on input voice volume, keyword utterance duration, ambient noise, and preset volume control parameters, allowing for real-time adaptation of sound output levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the output volume is preset at a significantly high level, then the audio content can be heard clearly, but the user or people around may be surprised or disturbed by the loud sound

Engineering Contradiction:

Improveoutput volumeVSAvoiduser surprise or disturbance

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The system measures the input volume of the user's voice and uses this feedback to automatically adjust the output volume. The voice input measuring unit quantifies the volume of the user's voice, and the output volume is set based on this measurement, creating a closed-loop feedback system that adapts to user behavior patterns.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system serves itself by automatically adjusting its own output volume based on the characteristics of the user's input voice. No manual intervention is required - the system autonomously determines the appropriate output level by analyzing the input voice volume and applying predefined relationships or machine learning models.

Inventive Principle:

Principle #25Self-service

2Object-affected harmful factors

If the output volume is preset at a significantly low level, then the sound is pleasant to hear, but the user may not properly hear the audio or answer

Engineering Contradiction:

Improveuser comfortVSAvoidoutput volume

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The system continuously monitors the user's voice volume and adjusts the output volume in real-time based on this feedback. When the user speaks loudly, the output volume increases; when the user speaks softly, the output volume decreases, ensuring optimal audibility while maintaining comfort.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The output volume is not fixed but dynamically adjusted based on the user's voice characteristics. The system adapts the output volume in real-time according to the measured input voice volume, creating a dynamic response that matches user behavior and environmental conditions.

Inventive Principle:

Principle #15Dynamics

3Illumination intensity

If the output volume is manually adjusted after the user hears the sound, then the volume can be optimized, but the user experience is degraded due to the delay and additional操作步骤

Engineering Contradiction:

Improveoutput volumeVSAvoiduser convenience

Core Design Contradiction:

Illumination intensityVSEase of operation

Solution Approach 1:

The system performs preliminary action by automatically setting the appropriate output volume before the user needs to hear the audio content. By measuring the user's voice volume in advance and pre-adjusting the output volume accordingly, the system eliminates the need for manual adjustment and ensures optimal volume from the start.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system serves itself by automatically adjusting its output volume without requiring user intervention. The volume control function is self-executing, based on the measured characteristics of the user's voice input, thereby improving ease of operation by eliminating manual adjustment steps.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If the output volume is automatically adjusted based on input voice volume, then the user experience is improved, but the device complexity increases due to additional measuring and control units

Engineering Contradiction:

Improveautomatic volume controlVSAvoidsystem structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The voice input measuring unit serves multiple functions: it measures the volume of the user's voice for output volume control, and can also be used for other voice-based processing tasks. This multi-functionality reduces the need for separate dedicated components, thereby mitigating the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The volume measurement and output control functions are merged into an integrated system. The same voice input measuring unit that captures voice characteristics is directly coupled with the output volume control mechanism, eliminating the need for separate independent components and reducing overall system complexity.

Inventive Principle:

Principle #5Merging (Combining)
