Elastic Headset Frame with Adjustable Contact Microphone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headsets using bone conduction technology face challenges in ease of wear due to inflexible designs that do not accommodate varying head sizes and shapes, leading to discomfort and inconvenience during use.
Innovation Solution
A headset design featuring a frame with elasticity that supports bone conduction speakers and contact type microphones, with movable parts that adjust the distance between the microphones and the frame, allowing for flexible positioning and easy wear by rotating or sliding mechanisms to accommodate different head sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the headset uses a fixed rigid structure, then the manufacturing precision is improved, but the adaptability to different head sizes and shapes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by introducing a movable part that can change position along the frame. This allows the distance between the contact type microphone and the frame to be adjusted, enabling the headset to adapt to different head sizes and shapes while maintaining structural integrity through the elastic frame
Solution Approach 2:
The patent applies parameter changes by modifying the distance parameter between the contact type microphone and the frame. The movable part enables this distance to be changed, allowing the headset to accommodate varying head dimensions while maintaining proper contact for voice signal acquisition
2Ease of operation
If the headset uses a flexible adjustable design, then the ease of wear is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the headset into distinct functional modules: an elastic frame, a contact type microphone, and a movable part. This modular segmentation allows the movable part to provide adjustment functionality for ease of wear while keeping the overall structural complexity manageable through clear functional separation
3Measurement precision
If the contact type microphone is positioned close to the frame, then the voice signal quality is improved, but the ease of wear deteriorates
Solution Approach 1:
The patent applies dynamics by making the microphone position adjustable rather than fixed. The movable part enables the microphone to be positioned close to the frame for optimal voice signal quality when needed, while allowing the headset to be worn more comfortably by adjusting the distance when ease of wear is the priority
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
