Monaural Wireless Headset Concha Hook Secure Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monaural wireless headsets face challenges in providing both comfortable wearing and secure holding, with conventional designs often compromising on sound quality, ease of use, or requiring customization for each user.
Innovation Solution
A monaural wireless headset design featuring a cylindrical main body and a rod-shaped microphone boom with a rechargeable lithium-ion battery, where the microphone and speaker are positioned to fit comfortably within the ear's concha, allowing for adjustable fit and secure placement using an elastic earbud and support surface, ensuring balanced weight distribution and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic bracket is used to surround the outer ear for secure holding, then the headset can be held securely, but the wearing comfort deteriorates
Solution Approach 1:
The invention removes the elastic bracket that surrounded the outer ear and replaces it with a hook that engages with the concha. This extracts the uncomfortable element while preserving the secure holding function through the hook's engagement mechanism with the concha's anatomical structure.
Solution Approach 2:
The invention introduces a hook as an intermediary element that connects the headset to the concha. This hook acts as a mediator that provides secure holding through mechanical engagement with the concha's structure, avoiding direct pressure on the outer ear while maintaining reliability.
2Ease of operation
If an elastic member pressing against the inner wall of the concha is used for wearing comfort, then the wearing comfort improves, but the secure holding deteriorates
Solution Approach 1:
The invention removes the elastic member that pressed against the inner wall of the concha and replaces it with a hook structure. This extraction eliminates the comfort-security trade-off by using a different mechanical principle (hook engagement) that provides both comfort and secure holding simultaneously.
Solution Approach 2:
Instead of using pressure against the concha wall for holding, the invention inverts the approach by using a hook that engages with the concha's external structure. This inversion allows the headset to be held securely through mechanical interlocking rather than pressure, improving both security and comfort.
3Reliability
If the speaker driver extends into the concha for sound quality, then the sound quality improves, but the device complexity increases
Solution Approach 1:
The invention segments the housing into distinct functional portions: a main body containing electronics and a separate speaker driver portion that extends into the concha. This segmentation allows the speaker driver to be positioned for optimal sound quality while keeping the main body structure simple and suitable for mass production.
Solution Approach 2:
The invention applies local quality by giving the speaker driver portion a specific shape optimized for extending into the concha, while the main body maintains a simpler cylindrical shape. This localized optimization allows sound quality improvement without increasing overall device complexity, as only the speaker portion has the specialized geometry.
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
The headset achieves improved comfort and secure holding without compromising sound quality or manufacturing complexity, allowing for mass production without individual customization, while maintaining an acceptable operating time and ease of use.
Implementation Method 1
a rechargeable lithium-ion battery
Implementation Method 2
an elastic earbud with a support surface adapted to abut an inwardly inclined surface portion of an antitragus crest when the headset is in the wearing position

AI summary
The present invention relates to a monaural wireless headset (20) that may e.g. be connected to a mobile phone by means of a Bluetooth connection. The present invention provides a monaural wireless headset (20) comprising a housing (21) with a main body (22) and a microphone boom (23), a microphone (27), a wireless transceiver (28), a speaker driver (39) and a rechargeable battery (29). The monaural wireless headset (20) is adapted to be arranged at an ear (1) of a user in a wearing position wherein at least a portion of the main body (22) resides on the inwards side of the crest (7) of the ear's antitragus (6) and wherein the microphone boom (23) at least partly extends outside the ear's pinna (1) towards the user's mouth. The microphone (27) is arranged in the microphone boom (23) and is adapted to receive a voice signal from the user and provide a microphone signal to the wireless transceiver (28) in dependence on the voice signal. The wireless transceiver (28) is adapted to transmit a wireless output signal in dependence on the microphone signal. Furthermore, the wireless transceiver (28) is adapted to receive a wireless input signal and provide an audio output signal to the speaker driver (39) in dependence on the wireless input signal. The speaker driver (39) is arranged and adapted to transmit a sound signal into the ear (1) in dependence on the audio output signal, and the rechargeable battery (29) is adapted to provide electric power to the wireless transceiver (28) and the speaker driver (39). The monaural wireless headset (20) is characterized in that the speaker driver (39) and the rechargeable battery (29) are arranged in the main body (22) in such a way that the speaker driver (39) and at least a portion of the rechargeable battery (29) reside on the inwards side of the crest (7) of the antitragus (6) when the monaural wireless headset (20) is in the wearing position. This may provide a monaural wireless headset (20) that allows a comfortable wearing and a secure holding of the headset (20) when in use.
