Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling and interacting with wearable audio output devices, such as headphones and earbuds, are cumbersome, inefficient, and limited, particularly in terms of audio routing, volume control, and energy consumption, especially in battery-operated devices.
Innovation Solution
Implementing improved methods and interfaces for wearable audio output devices and charging cases that include touch-sensitive surfaces, display devices, and graphical user interfaces, allowing for efficient audio routing, volume adjustment, and power conservation through reduced user inputs and enhanced feedback mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the entire display screen is lit to display visual elements, then the user can see status information, but energy is wasted
Solution Approach 1:
The patent applies local quality by illuminating only specific portions of the display screen rather than the entire screen. The display controller selectively activates individual display elements or regions based on the information that needs to be conveyed, thereby reducing overall energy consumption while maintaining necessary visual feedback functionality.
2Ease of operation
If conventional control methods are used for audio output devices, then basic functions can be operated, but the control process is cumbersome and inefficient
Solution Approach 1:
The audio output device case provides self-service functionality by directly controlling audio routing and volume without requiring a companion device. The case itself becomes the control interface, detecting user inputs through its interface elements and automatically adjusting audio parameters, thereby eliminating the need for additional devices and reducing operational time.
Solution Approach 2:
The display screen serves multiple functions: it displays status information, provides visual feedback for audio routing modes, and shows volume level indicators. This multi-functionality consolidates what would otherwise require separate indicators or interfaces into a single universal display element, improving ease of operation.
3Device complexity
If limited control inputs are provided at the audio output device case, then the device structure remains simple, but the user cannot control volume or audio routing
Solution Approach 1:
The display screen acts as an intermediary that communicates audio routing mode information to the user. Rather than requiring complex physical controls for each audio source, the display visually indicates the current audio routing state, and simple interface elements can trigger routing changes. This mediator approach provides versatile control capability while maintaining relatively simple device structure.

AI summary
An audio output device case includes a display device. While the display device is disabled, the display device and an exterior of the audio output device case meet similarity criteria. The audio output device case detects an occurrence of a first event. In response to detecting the occurrence of the first event and in accordance with a determination that the display device is disabled, the display device is enabled. A dynamic visual element corresponding to the first event is displayed via a first portion of the display device. The dynamic visual element changes over time. While the display device is enabled, a second portion of the display device, distinct from the first portion of the display device, and the exterior of the audio output device case meet the similarity criteria.
