Solution Overview

Problem

Consumer-based HVAC equipment noise interferes with home entertainment devices due to its intermittent operation, requiring frequent manual volume adjustments by users.

Innovation Solution

A system and method for automatically controlling the volume of home entertainment devices by detecting the activation or deactivation of HVAC components using a thermostat or portable electronic device, which sends volume control signals to adjust the volume accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If HVAC components are operated to heat or cool the residence, then temperature regulation is achieved, but audio interference is generated that disrupts home entertainment devices

Engineering Contradiction:
Improvetemperature regulationVSAvoidaudio interference
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The system proactively increases the volume of home entertainment devices before HVAC components are activated, based on predictive detection of upcoming HVAC operation. This preliminary volume adjustment ensures that entertainment audio remains audible despite the impending noise from HVAC equipment, resolving the contradiction by preparing the system in advance rather than reacting after interference occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors HVAC component status and dynamically adjusts entertainment device volume in real-time based on detected HVAC operation. This feedback mechanism allows the system to respond to actual HVAC activity, automatically increasing volume when HVAC components are running and decreasing it when they are off, thereby maintaining temperature regulation while mitigating audio interference.

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If users manually adjust the volume of home entertainment devices to compensate for HVAC noise, then audio quality is maintained, but user convenience deteriorates due to frequent adjustments

Engineering Contradiction:
Improveaudio qualityVSAvoiduser convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system enables home entertainment devices to automatically adjust their own volume based on detected HVAC operation, eliminating the need for manual user intervention. The thermostat or controlling device monitors HVAC status and autonomously sends volume control signals to entertainment devices, allowing the system to self-regulate audio quality without requiring users to repeatedly manually adjust volumes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements automatic feedback-based volume control where the thermostat detects HVAC component activation and automatically adjusts entertainment device volume accordingly. This eliminates manual adjustment operations while maintaining audio quality, as the system continuously monitors HVAC status and responds autonomously, thereby improving ease of operation without sacrificing audio performance.

Inventive Principle:
Principle #23Feedback

3Object-affected harmful factors

If the volume of home entertainment devices is increased to overcome HVAC noise, then audio clarity is improved, but noise pollution increases when HVAC is not operating

Engineering Contradiction:
Improveaudio clarityVSAvoidnoise pollution
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The system dynamically adjusts the volume of home entertainment devices based on real-time HVAC operational status. When HVAC components are active, the system increases entertainment volume to maintain audio clarity. When HVAC components are inactive, the system automatically decreases entertainment volume to normal levels, preventing excessive noise pollution. This dynamic adjustment resolves the contradiction by making volume adaptable to environmental conditions rather than fixed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the volume parameter of home entertainment devices in response to HVAC operational states. Volume is increased only when HVAC noise is present and decreased when HVAC is off, optimizing audio clarity during HVAC operation while minimizing noise pollution during normal operation. This parameter adjustment based on environmental conditions resolves the contradiction between maintaining audio quality and preventing excessive noise.

Inventive Principle:
Principle #35Parameter changes
