Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

When a third electronic device is connected to an electronic device while a second electronic device is playing multimedia content, the specialized functions of the second device, such as noise-canceling or ambient light adjustments, can disrupt the user's experience, leading to inconvenience.

Innovation Solution

A method is provided to control a content playing device that identifies and connects a third electronic device, determines the presence of specialized functions in the second device, and either plays the content on the third device or deactivates these functions to maintain a consistent user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a third electronic device is connected to an electronic device while a second electronic device plays multimedia content, then the third device can seamlessly play the content, but the specialized functions of the second device (noise-canceling, ambient light adjustments) disrupt the user's experience

Engineering Contradiction:

Improveseamless content playback across devicesVSAvoiduser experience disruption from specialized functions

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection to identify when a third device is connected while content is playing on a second device. Before the specialized functions can disrupt the user experience, the system proactively deactivates noise-canceling and ambient light adjustments on the second device, preventing the harmful effect rather than correcting it afterward.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The electronic device (first device) acts as an intermediary that coordinates between the second device (playing content) and the third device (newly connected). It monitors the playback state and controls the specialized functions of the second device based on the presence of the third device, mediating the interaction to prevent user experience disruption.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If specialized functions like noise-canceling are activated in the second electronic device, then audio quality is improved, but these functions continue to affect the user's senses even when content plays on the third device

Engineering Contradiction:

Improveaudio quality from specialized functionsVSAvoidresidual effect on user's sight, touch, and hearing

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system implements feedback by continuously monitoring which device is currently playing content. When the third device is detected as the active playback device, the system responds by deactivating the specialized functions on the second device, creating a feedback loop that adapts the audio processing to the current playback state and eliminates residual harmful effects on the user's senses.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The specialized functions are made dynamic rather than static. The noise-canceling and ambient light adjustments are automatically activated or deactivated based on real-time conditions - specifically, whether the second device or third device is playing content. This dynamic adaptation ensures audio quality when needed while preventing sensory disruption when not needed.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If the second electronic device maintains active specialized functions during content playback, then the function settings are preserved, but the user experiences inconvenience from continuous activation

Engineering Contradiction:

Improvefunction setting consistencyVSAvoiduser convenience during device switching

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

AI summary

A method of controlling a content playing device and an electronic device performing the method are provided. The method of controlling a content playing device includes playing content on a second electronic device connected to an electronic device, identifying, by the electronic device, a third electronic device and connecting the electronic device to the third electronic device, determining whether a specialized function related to playing the content is present among functions of the second electronic device, and playing the content, played on the second electronic device, on the third electronic device.
