Solution Overview

Problem

Users of display devices like televisions often face confusion when internal speakers are disabled after connecting external sound systems, leading to a frustrating experience as they may not know how to enable the internal speakers or the external system, resulting in no sound when trying to adjust the volume.

Innovation Solution

A processor-based system that determines if the internal speaker is disabled and the external sound system is unavailable, prompting the user with an option to enable the internal speaker, thereby allowing audio to be played through the internal speaker if the external system is not functioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the internal speaker is disabled when an external sound system is connected, then the external sound system can be used, but the user experiences confusion and cannot hear sound when trying to adjust volume

Engineering Contradiction:
Improveexternal sound system compatibilityVSAvoiduser confusion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system provides visual feedback through an on-screen prompt that informs users when the internal speaker is disabled and offers an option to re-enable it. This feedback mechanism resolves the user confusion by clearly communicating the current audio output state and providing actionable guidance.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically detects when no external sound system is available and self-corrects by prompting the user to enable the internal speaker, allowing the device to serve itself in restoring audio functionality without requiring user knowledge of the disablement cause.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the internal speaker remains enabled by default, then users can always hear sound, but external sound systems cannot be properly utilized

Engineering Contradiction:
Improveaudio availabilityVSAvoidexternal sound system usage
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the audio output configuration based on the connection status of external sound systems. When an external system is detected, the internal speaker is disabled; when not detected, the system prompts to enable it, making the audio configuration adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display device is designed to support multiple audio output modes (internal speaker and external sound system) universally. The system can switch between these modes based on connectivity, ensuring both internal and external audio paths remain viable options for different user scenarios.

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

3Reliability

If the system automatically enables the internal speaker when external system is unavailable, then audio functionality is restored, but user control and choice are reduced

Engineering Contradiction:
Improveaudio functionalityVSAvoiduser control
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Instead of directly enabling the internal speaker without user input, the system introduces an intermediary prompt that mediates between the detected external system unavailability and the actual enabling action. This prompt preserves user control while guiding them toward restoring audio functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A display device has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to make a first determination that an internal display device speaker is disabled. A second determination that an external sound system is unavailable is established. A prompt is provided in response to the first determination and the second determination. The prompt includes an option to enable the internal display device speaker.
