Headset Cord Illumination for Dual-Angle Status Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio headsets struggle to display status information in a way that is visible both to the wearer and to others around them, as status lights on ear-level modules or in-line controllers are often obscured.
Innovation Solution
An audio headset with an illumination source, such as a string of LEDs or a light pipe, is integrated along a segment of the cord, allowing both the wearer and nearby individuals to see status semaphores through a controller that detects control signals and produces light patterns or color combinations indicating the headset's status, such as incoming calls, active calls, or streaming audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If status lights are placed on the ear level module, then the wearer can see the status, but people around the wearer cannot see the status
Solution Approach 1:
The patent extends the status indication from a single point (ear level module) to a linear distribution along the cord. By placing multiple illumination sources at different positions along the cord, the system creates multiple viewing planes and angles, allowing both the wearer and people around to see status indicators simultaneously from different spatial perspectives.
Solution Approach 2:
The patent divides the status indication function into multiple segments along the cord. Instead of a single status light, multiple illumination sources are distributed along different segments of the cord, each capable of displaying status information. This segmentation allows different portions of the cord to be visible to different observers simultaneously.
2Loss of information
If status lights are placed on an in-line controller or light module on a cord, then the status can be seen from a distance, but the lights may be obscured below a desk or in other positions
Solution Approach 1:
The patent divides the status indication function into multiple segments along the cord. Instead of a single status light, multiple illumination sources are distributed along different segments of the cord, each capable of displaying status information. This segmentation allows different portions of the cord to be visible to different observers simultaneously.
Solution Approach 2:
The patent makes different parts of the cord have the same functional property (status indication capability) rather than concentrating it in one location. Each segment of the cord with an illumination source can independently display status, ensuring that if one segment is obscured, other segments remain visible from different angles and positions.
3Loss of information
If multiple illumination sources are distributed along the cord, then visibility to both wearer and others is improved, but the device complexity increases
Solution Approach 1:
The cord serves multiple functions: it transmits audio signals, power, and now also serves as a distributed display medium for status indication. By making the cord itself a multi-functional element that can display status along its length, the patent avoids adding separate display components and reduces overall system complexity.
Solution Approach 2:
The patent merges the status indication function with the existing cord structure. Instead of adding separate display devices or modules, the illumination sources are integrated directly into the cord, combining the functions of signal transmission and visual status indication in a single integrated system.

Function Achieved in This Case
Enables clear and visible status indication for both the wearer and surrounding people, enhancing usability and communication in various settings.
Implementation Method 1
An illumination source, such as a string of LEDs or a light pipe with emission surfaces, is disposed along a segment of the cord
Data Source
AI summary
A headset includes an ear level module including a speaker and a receiver which drives the speaker. A cord configured to carry control signals and audio signals for the receiver is connected to the headset. An illumination source is disposed along a segment of the cord spanning a range selected to be visible to the wearer and persons near the wearer. The cord includes a plurality of wires configured to carry audio signals and control signals, and one or more wires connected to the illumination source configured to carry light control signals from a controller. The controller includes circuitry responsive to control signals transmitted on the cord to provide light control signals to cause the illumination source to produce status semaphores indicating status of use of the headset.
