Collar-Clipped TWS Hearing Aid Charging Case for Independent Earbud Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TWS Bluetooth hearing aids are designed as integrated structures for both ears, requiring simultaneous use and are bulky, making them inconvenient to carry.
Innovation Solution
A TWS Bluetooth hearing aid with a housing that secures on the wearer's collar via a clamping mechanism, featuring a clamping mechanism with a buckle ring and rotating rod, magnetic attraction, and a charging mechanism with telescopic columns and springs to allow independent use and charging of each earphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If TWS Bluetooth hearing aids are designed as integrated dual-ear structures, then both ears can be used simultaneously for stereo sound, but the device becomes bulky and inconvenient to carry
Solution Approach 1:
The patent divides the hearing aid system into separate left and right earphone units that can be used independently. Each earphone contains its own microphone, battery, and control circuitry, allowing them to function as standalone mono hearing aids or combine for stereo mode, thus reducing the bulk of each individual unit while maintaining stereo capability
2Adaptability or versatility
If TWS Bluetooth hearing aids require simultaneous use on both ears, then stereo functionality is achieved, but usability becomes limited when only one ear needs assistance
Solution Approach 1:
Each earphone is designed as an independent functional unit with complete hearing aid capabilities including microphone, amplifier, battery, and Bluetooth module. This segmentation allows users to wear one or both earphones based on their needs, providing flexibility for mono or stereo usage scenarios
Solution Approach 2:
The earphones are designed to serve multiple functions: they can be used individually as mono hearing aids, paired together for stereo sound, or used as wireless audio devices. The universal design allows a single device to adapt to various usage scenarios without requiring different equipment
3Reliability
If a clamping mechanism is added to fix the housing on the wearer's collar, then the hearing aid can be worn more securely, but the device structure becomes more complex
Solution Approach 1:
A clamping mechanism serves as an intermediary component between the housing and the wearer's collar. This separate clamping device attaches to the housing and then secures to the collar, providing reliable fixation without requiring the housing itself to be structurally modified for clamping integration
4Reliability
If magnetic attraction pieces are added to fix the earphone in the connecting slot, then charging contact reliability is improved, but the device becomes more complex
Solution Approach 1:
Magnetic attraction pieces are introduced as intermediary elements between the earphone and the connecting slot. These magnets create an attractive force that automatically draws the earphone into proper alignment with the charging contacts, ensuring reliable electrical connection without requiring complex mechanical alignment mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables clear hearing by converting external speech into information transmitted via Bluetooth, allows independent wearing, and enhances charging effectiveness through magnetic fixation and electrical energy transfer.
Implementation Method 1
a magnetic attraction piece is provided on a bottom wall of the connecting slot at one side thereof. The magnetic attraction piece attracts a magnetic piece on a lower part of the earphone so as to fix the earphone in the connecting slot through magnetic attraction.
Implementation Method 2
a torsion spring is arranged on a middle part of the rotating rod. Two ends of the torsion spring are fixed to the buckle ring and the pressing plate, respectively. When the pressing plate is acted on by an external force to rotate outward, the torsion spring acts on the buckle ring, and when the external force is removed, the torsion spring returns pushes the pressing plate to move towards the side wall of the housing.
Implementation Method 3
a spring is provided on a bottom wall of the telescopic groove. A telescopic column is arranged partly inside the spring. An upper part of the telescopic column extends through an opening of the fixed column in communication with the telescopic groove and has a contact point at a distal end and contactable with an electrode piece on a bottom end of the earphone to achieve electrical energy transfer.

AI summary
A TWS Bluetooth hearing aid includes a housing. Connecting slots are formed in an upper part of the housing at two sides thereof. Each connecting slot has an inlet, in which an earphone is receivable such that a bottom end of the earphone contacts a charging connection mechanism. A clamping mechanism is arranged on one side of an external wall of the housing, and a hearing microphone is arranged on an opposite side of the external wall. The hearing microphone is connectable to the earphone via Bluetooth. The housing is selectively fixed to a wearer's collar through the clamping mechanism, and external speech is receivable by the hearing microphone arranged on the housing to convert into information that is then transmitted via Bluetooth to the earphone to be played back so as to make it easier for the wearer to hear the speech clearly.
