Display Device Volume Adjustment via Hearing Aid Bluetooth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adjusting the volume of hearing aids are inconvenient, requiring users to remove the hearing aid to operate volume adjustment buttons or establish a connection using a separate remote control.
Innovation Solution
A display apparatus with a user interface, communicator, and processor that receives volume adjustment instructions, adjusts its own volume, establishes a Bluetooth connection with a hearing aid, and adjusts the hearing aid's volume based on ambient sound levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If volume adjustment buttons on the hearing aid are used, then volume control is achieved, but the hearing aid must be removed from the ear for operation which reduces convenience
Solution Approach 1:
The patent introduces a display apparatus as an intermediary device that receives volume adjustment instructions and transmits control signals to the hearing aid via Bluetooth connection. This mediator enables volume adjustment without requiring the user to physically interact with the hearing aid itself, resolving the contradiction by providing remote control capability while maintaining the hearing aid in place in the ear.
Solution Approach 2:
The display apparatus serves multiple functions: it acts as both a display device and a remote control for the hearing aid. By integrating volume adjustment capability into the display apparatus, the system eliminates the need for separate control mechanisms and provides a unified interface for controlling both devices, thereby improving operational convenience.
2Ease of operation
If a separate hearing aid remote control is used, then volume adjustment is possible, but establishing a connection between the remote control and hearing aid adds operational complexity
Solution Approach 1:
The patent merges the functions of the display apparatus and the hearing aid remote control into a single integrated system. The display apparatus directly communicates with the hearing aid through established Bluetooth connectivity, eliminating the need for a separate remote control device and its associated connection establishment process. This consolidation reduces operational complexity while maintaining volume adjustment functionality.
3Device complexity
If the display apparatus controls only its own volume, then simple control is maintained, but the hearing aid volume cannot be adjusted remotely
Solution Approach 1:
The display apparatus is enhanced to perform dual functions: controlling its own volume and remotely controlling the hearing aid volume. By receiving volume adjustment instructions and transmitting appropriate control signals to the hearing aid, the display apparatus becomes a multi-functional device that addresses both control needs without significantly increasing system complexity.
Solution Approach 2:
The system implements feedback mechanisms where the display apparatus receives volume adjustment instructions, processes them, and transmits control signals to the hearing aid. The hearing aid responds to these commands, and the system monitors the volume changes to ensure proper execution. This feedback loop enables reliable remote control functionality while maintaining system simplicity.

AI summary
The present disclosure provides a display device and a volume adjustment method. The display device includes: a display, a user interface, a communicator, a memory, and at least one processor. The at least one processor is configured for: receiving a first volume adjustment instruction; adjusting the volume of the display device according to the first volume adjustment instruction, and acquiring a first volume value and a second volume value where the display device has established a Bluetooth connection with a hearing aid supporting a HAS; and when determining according to the first volume value and the second volume value that a condition for adjusting the volume of the hearing aid is met, acquiring the loudness of ambient sounds; generating a second volume adjustment instruction according to the loudness of the ambient sounds; and sending the second volume adjustment instruction to the hearing aid by means of the Bluetooth connection.
