Wearable Display Speaker Positioning via Slidable Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic displays often fail to provide satisfactory viewing and sound due to inconsistent head sizes among users, as existing technologies lack effective size adjustments for secure and comfortable fit.
Innovation Solution
A wearable electronic display system featuring a flexible band with slidable mounts for adjustable speaker positioning and a resilient forehead support, allowing for customizable fit to various head sizes, with speakers mounted below the band and angled stems for optimal ear alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If speakers are fixed rigidly to the wearable display, then structural stability is improved, but adaptability to different head sizes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the speaker mounting structure adjustable rather than fixed. The speakers can be repositioned along the headband to different locations, allowing the wearable display to adapt to various head sizes and shapes while maintaining stable speaker positioning during use.
Solution Approach 2:
The patent segments the speaker mounting system into independent adjustable components. Each speaker is mounted on a separate adjustable mechanism that allows independent positioning, enabling customization for different users' head dimensions while maintaining overall structural integrity.
2Reliability
If the flexible band constrains the head significantly, then securement is improved, but comfort deteriorates
Solution Approach 1:
The patent applies local quality by making the flexible band selectively constraining only in specific regions where securement is needed, while remaining non-constraining in other regions to maintain comfort. The band is designed to flex and adapt locally to different head shapes without applying excessive pressure across the entire head.
3Manufacturing precision
If slidable mounts have large dimensions, then speaker positioning precision is improved, but the amount of flexible band constrained increases
Solution Approach 1:
The patent introduces an intermediary slidable mount mechanism that enables precise speaker positioning without requiring large dimensions. The slidable mount acts as a mediator between the flexible band and the speaker, providing accurate positioning through a compact design that minimizes the amount of flexible band consumed.
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 a secure, comfortable, and adjustable fit for users of different head sizes, ensuring optimal viewing and sound quality by minimizing the flexible band's constraint on the head and allowing for precise speaker placement.
Implementation Method 1
A resilient forehead support can extend from the eyewear display rearwardly for providing support against the user's forehead. The forehead support can include a rubber member having elongate lateral slots for providing flexibility to the forehead support to adjust to different head sizes.
Implementation Method 2
Each slidable mount can include a narrow flattened post having a slot through which the flexible band extends. The speakers can be slidably attached below the flexible band by a slidable mount, capable of sliding forwardly and rearwardly on the flexible band for adjusting the at least one speaker to the user's ears.
