Solution Overview

Problem

Existing audio processing devices fail to dynamically adapt and optimize audio signal distribution among multiple devices based on their proximity and positioning, leading to suboptimal sound reproduction and spatial rendering.

Innovation Solution

An audio processing device with a detection module that uses Zigbee, Wi-Fi, or Bluetooth technology to detect nearby devices, pair them, and dynamically adjust audio signal distribution based on distance and relative positioning, allowing for adaptive specialization of audio functionality among devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If multiple audio processing devices are used in proximity, then sound power and spatial rendering are enhanced, but automatic adaptation and optimization of audio signal distribution based on device positioning are not achieved

Engineering Contradiction:
Improvesound powerVSAvoidautomatic adaptation to device positioning
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts audio signal distribution based on real-time detection of device proximity and positioning. Audio processing devices automatically adjust their functionality and signal routing according to the number and relative positions of nearby devices, transforming a static system into a dynamic one that responds to environmental changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The detection module continuously monitors the presence and positioning of nearby audio processing devices, providing feedback information about device proximity. This feedback enables the system to automatically optimize audio signal distribution and specialization of functionality based on the current spatial configuration of devices.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If manual configuration of audio signal distribution is implemented, then control precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvecontrol precisionVSAvoidease of configuration
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The audio processing device automatically detects nearby devices and configures audio signal distribution without requiring manual user intervention. The system performs self-configuration by detecting device proximity through the detection module and automatically optimizing signal routing and functionality specialization, eliminating the need for manual setup while maintaining precise control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection of device proximity and positioning before audio playback begins. By pre-configuring the audio signal distribution based on detected device positions, the system ensures optimal sound reproduction from the start without requiring users to manually adjust settings during operation.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If fixed functionality assignment is used, then device complexity is reduced, but adaptability to different spatial configurations deteriorates

Engineering Contradiction:
Improvefunctional configurationVSAvoidadaptation to number of devices
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system transitions from fixed functionality assignment to dynamic functionality specialization. Audio processing devices automatically adjust their operational roles and signal distribution based on the number and positioning of nearby devices, enabling the same hardware to adapt to various spatial configurations without increasing physical complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Each audio processing device is designed with universal capabilities to perform multiple functions. Through automatic detection and dynamic configuration, devices can specialize in different roles (e.g., primary audio source, supplementary speaker, spatial effect processor) based on the detected spatial arrangement, allowing a single device type to serve multiple purposes in different configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
