Solution Overview

Problem

Conventional headsets do not provide a clear visual indication of whether the user is listening to an audio signal, making it difficult for others to determine if the user can hear external noises or comments.

Innovation Solution

A headset with flashing LEDs that vary in intensity, frequency, and pattern based on the audio signal characteristics, including a control circuit to manage different operation modes such as normal and saturation modes, and a microphone for sound detection in night use mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional headsets are used without visual indicators, then the device structure remains simple, but others cannot determine if the user is listening to audio signals

Engineering Contradiction:
Improvevisual indication of audio signal statusVSAvoidheadset structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies color changes by using LEDs that emit different colors or flash patterns to indicate audio signal status. The LEDs are integrated into the headset structure and respond to audio signals by changing their optical properties, providing visual feedback without significantly complicating the overall device design.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent utilizes parameter changes by varying the intensity, frequency, and pattern of LED flashes based on audio signal characteristics such as volume and rhythm. The control circuit dynamically adjusts these parameters to provide meaningful visual indication of the audio status while maintaining a relatively simple headset structure.

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If LEDs are added to indicate audio signal status, then visual feedback is provided, but energy consumption increases

Engineering Contradiction:
Improvevisual feedback of listening statusVSAvoidheadset energy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent applies periodic action by making the LEDs flash in rhythm with the audio signal rather than remaining continuously illuminated. This periodic activation synchronized with the audio beats provides visual feedback while significantly reducing overall energy consumption compared to continuous operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent implements dynamics by making the LED intensity and flash patterns variable based on audio signal characteristics. The control circuit dynamically adjusts LED operation parameters such as brightness and flash frequency according to the audio volume and rhythm, optimizing energy usage while maintaining effective visual communication.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple operation modes are implemented, then functionality is enhanced, but control circuit complexity increases

Engineering Contradiction:
Improveoperation modesVSAvoidcontrol circuit
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the control circuit to handle multiple operation modes (normal mode, saturation mode, night use mode) using a single integrated system. The same control circuit adapts its behavior based on detected conditions such as audio volume thresholds and ambient light levels, providing multiple functions without requiring separate dedicated circuits for each mode.

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

AI summary

A headphone system is provided with two earbud headphones and a control module, each fitted with a plurality of light emitting diodes (LEDs). The LEDs may be of many different colors and flash to the beat of the music. Patterns, colors, and intensity may be adjusted based on a user's preferences. The intensity, frequency, and light patterns of the LEDs may change when a threshold level is reached.
