Solution Overview

Problem

Users often forget to take regular breaks while using earphones to prevent hearing damage, as existing multimedia players require manual monitoring of playback time, which is ineffective when not using earphones.

Innovation Solution

A multimedia playing system with an audio outputting device equipped with a distance detector that generates a signal when in use, transmitting this signal to the multimedia player to track usage time and prompt the user to take a break after exceeding a 30-minute threshold.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the total time period is displayed on the screen or toolbar, then the user can see the playback time, but the user still forgets to monitor it and take breaks

Engineering Contradiction:

Improvetime period informationVSAvoiduser monitoring effort

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system provides active feedback by detecting when the earphone is worn (via distance detector) and automatically monitoring the usage time. When the threshold is exceeded, the system generates a prompt event to alert the user, creating a closed-loop feedback mechanism that eliminates the need for manual monitoring while ensuring timely break reminders.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The multimedia player automatically performs the monitoring function without requiring user intervention. The distance detector and controller work together to self-monitor the earphone usage time and automatically generate alerts when necessary, making the system serve itself rather than relying on user attention.

Inventive Principle:

Principle #25Self-service

2Device complexity

If manual monitoring of playback time is required, then the system structure remains simple, but the effectiveness of hearing protection is reduced

Engineering Contradiction:

Improvesystem structureVSAvoidhearing protection effectiveness

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent replaces manual mechanical monitoring (user visually checking the screen) with an automated sensing system. The distance detector uses optical or electromagnetic fields to detect the presence of the ear on the earphone, and the controller automatically tracks time and generates alerts, substituting human action with automated electronic detection and control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The distance detector serves multiple functions: it detects whether the earphone is being worn, triggers the timing mechanism, and provides the basis for generating alerts. This multi-functional component reduces the need for separate sensors while improving the reliability of hearing protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of information

If the playback time display is always visible, then the time information is continuously available, but it becomes meaningless when not using earphones

Engineering Contradiction:

Improvetime information availabilityVSAvoidcontextual relevance

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The monitoring system dynamically activates based on the detected context. The distance detector determines whether the earphone is currently being worn, and the timing and alert functions are dynamically enabled or disabled accordingly. This makes the system adaptive to different usage contexts, ensuring time tracking is only active when relevant.

Inventive Principle:

Principle #15Dynamics

AI summary

A multimedia playing system includes an audio outputting device and a multimedia player. The audio outputting device includes a connecting plug and a distance detector. The distance detector generates a distance detecting signal if the distance detector detects the presence of a nearby object. The multimedia player is communicated with the audio outputting device through the connecting plug so as to transmit an output audio signal to the audio outputting device. The distance detecting signal is transmitted to the multimedia player through the connecting plug. The multimedia player generates a prompt event to the audio outputting device if the time duration of continuously receiving the distance detecting signal exceeds a time threshold.
