Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-ear headsets with boom microphones suffer from instability and user discomfort due to inadequate stabilization mechanisms, leading to unwanted modulation of the microphone signal during user movement.
Innovation Solution
A stabilized headband with pivot and rotation mechanisms, featuring contoured pads that are pivotably and rotatably coupled to the headband, providing improved alignment and stability of the microphone relative to the user's mouth, while distributing clamping force for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional in-ear headsets are used without stabilization mechanisms, then the device structure is simple, but the microphone position becomes unstable during user movement causing signal modulation
Solution Approach 1:
The headband incorporates dynamic stabilization mechanisms including a rotation mechanism that allows the boom microphone to rotate about a rotation axis, and a pivot mechanism with hinge joint that enables pivoting about a hinge axis. These dynamic mechanisms allow the microphone to maintain stable positioning relative to the user's mouth during movement, resolving the contradiction between stability and complexity by introducing controlled degrees of freedom rather than rigid fixation.
Solution Approach 2:
The stabilization system is segmented into distinct functional components: the rotation mechanism with rotating member and retaining pin, the pivot mechanism with hinge joint, and the boom assembly. This segmentation allows each component to perform its specific stabilization function independently, managing overall system complexity through modular design while achieving cumulative stability effects.
2Stability of the object's composition
If rigid stabilization mechanisms are added to maintain microphone position, then position stability improves, but user comfort decreases due to increased clamping force
Solution Approach 1:
The pivot mechanism incorporates a spring element that dynamically adjusts the clamping force parameter based on user head movements and headset weight. The spring provides compliant stabilization, maintaining microphone position stability while automatically modulating the clamping force to remain within comfortable ranges for the user, thus resolving the contradiction between stability and comfort through parameter adaptation.
3Adaptability or versatility
If the headband uses fixed pads, then the structure is simpler, but the pads cannot adapt to different user head shapes causing discomfort
Solution Approach 1:
The side pads are dynamically coupled to the headband through the pivot mechanism, allowing them to pivot about the hinge axis in response to user head shape variations. This dynamic coupling enables the pads to automatically adapt their position and orientation to different users without requiring complex adjustment mechanisms, achieving adaptability through motion rather than mechanical complexity.

AI summary
A stabilized headband may include a pivot mechanism. The pivot mechanism may be configured so that at least one pad is pivotable about at least one pivot axis and disposed between the at least one pad and one of first and second ends of the headband. The stabilized headband may further include a rotation mechanism. The rotation mechanism may be configured so that the at least one pad is rotatable about at least one rotation axis and disposed between the at least one pad and the one of the first and second ends of the headband.
