Solution Overview

Problem

Conventional audio devices, such as televisions, require user intervention to adjust volume levels based on different listening locations with varying acoustic properties, leading to inconsistent audio experiences.

Innovation Solution

The system learns user volume preferences based on historical data from various listening locations and automatically adjusts the device volume using wireless signal strength to determine the user's location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual volume adjustment is required for different listening locations, then the device can adapt to varying acoustic properties, but user convenience deteriorates due to required user intervention

Engineering Contradiction:

Improvevolume adaptation to listening locationVSAvoiduser convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects user location using wireless signal strength and retrieves pre-stored volume preferences for that location, eliminating the need for manual volume adjustment. The device serves itself by autonomously adapting volume based on acoustic properties of different listening areas.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Volume preferences for various listening locations are stored in advance in the database. When the user moves to a known location, the system retrieves the pre-stored volume setting immediately, avoiding real-time manual adjustment and enabling instant adaptation.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If automatic volume adjustment based on location is implemented, then user convenience improves, but device complexity increases due to additional sensors and processing

Engineering Contradiction:

Improveuser convenienceVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system uses an existing wireless communication infrastructure (Wi-Fi signals) as an intermediary to determine user location. Instead of adding dedicated sensors, the device leverages signal strength from existing wireless communications to infer user position and retrieve appropriate volume settings.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The wireless communication port, originally designed for data transmission, is also utilized for location detection by analyzing signal strength. This multi-functional use of existing components avoids adding dedicated hardware while enabling automatic volume adjustment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If volume preferences are stored for multiple locations, then adaptability to different acoustic environments improves, but data storage requirements increase

Engineering Contradiction:

Improvevolume preference storageVSAvoiddata storage

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system stores volume preferences specifically organized by location identifiers in the database. Each location has its own optimized volume setting stored locally, allowing the device to retrieve the appropriate setting based on current position without storing all possible configurations globally.

Inventive Principle:

Principle #3Local quality

AI summary

Systems and methods for automatically adjusting device volume based on learned volume preferences are disclosed herein. A first device receives a wireless signal from a second device. A signal strength of the wireless signal is determined, and a location of the second device is determined based on the signal strength of the wireless signal. Historical volume level data for the first device is retrieved from memory. A target volume level for the first device is determined based on the location of the second device and the historical volume level data. A volume setting of the first device is automatically adjusted to the target volume level.
