Solution Overview

Problem

Home audio speakers often struggle with limited low-frequency reproduction capabilities and require complex settings adjustments, which non-technical users find difficult to optimize, especially when speakers are moved within a room.

Innovation Solution

A networked speaker system that uses processor-executed algorithms to model and configure speaker settings, including equalization and location adjustments, to enhance low-frequency performance by distributing bass frequencies across multiple speakers based on their characteristics and locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple speakers are used to improve low-frequency reproduction, then bass performance is enhanced, but system complexity increases

Engineering Contradiction:
Improvelow-frequency reproduction capabilityVSAvoidspeaker system configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically performs speaker configuration, equalization, and positioning without requiring manual user input. The processor autonomously models speaker configurations, evaluates bass performance criteria, and adjusts parameters based on speaker characteristics and locations, eliminating the need for users to manually optimize settings.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts speaker parameters including equalization settings, volume levels, and frequency distribution based on modeled configurations. By automatically varying these parameters to satisfy bass frequency criteria, the system optimizes low-frequency reproduction without increasing user-configurable complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If automatic configuration is implemented to simplify user operation, then ease of operation improves, but processing time increases

Engineering Contradiction:
Improveuser configuration difficultyVSAvoidconfiguration setup time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system pre-establishes a comprehensive set of speaker configurations and equalization parameters before actual use. By pre-modeling multiple arrangements and preparing optimization algorithms in advance, the system can quickly determine the best configuration without requiring time-consuming real-time analysis during setup.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback loops where the processor evaluates bass frequency performance criteria against modeled configurations and automatically adjusts parameters. This iterative feedback process efficiently converges on optimal settings, reducing setup time while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback
