Flexible Stem Head-Worn Display for Adjustable Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-worn display apparatus with rigid stems fail to accommodate different head sizes, leading to discomfort and improper fit, as they do not allow for adjustment without compromising the alignment and position of digital imagery.
Innovation Solution
The use of adjustable stems that can flex or deform relative to the image source and frame, allowing for a customizable fit without altering the position of the image generator, coupled with connectors and locators to maintain precise imagery alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid stems are used in head-worn display apparatus, then the alignment and position of digital imagery is maintained, but the device cannot accommodate different head sizes leading to discomfort and improper fit
Solution Approach 1:
The stem is divided into multiple segments that can flex relative to each other, allowing the stem to bend and adapt to different head sizes while keeping the image generator portion rigid to maintain proper alignment and position of digital imagery
Solution Approach 2:
The stem transitions from a completely rigid structure to a dynamic structure with flexible portions that can bend and adjust, enabling the device to adapt to different users while maintaining image alignment through the rigid connected portions
2Ease of operation
If adjustable stems are used to accommodate different head sizes, then user comfort is improved, but the alignment and position of digital imagery may be compromised
Solution Approach 1:
The stem is segmented into flexible and rigid portions, where the flexible segments provide adjustability for user comfort while the rigid segments ensure precise manufacturing tolerances are maintained for image alignment
Solution Approach 2:
Different portions of the stem have different mechanical properties - the distal portions are flexible to provide comfort adjustment, while the proximal portions connected to the image generator are rigid to maintain precise alignment and position
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 comfortable fit for extended periods by accommodating various head sizes while maintaining the precise alignment and position of digital imagery, enhancing user comfort and usability.
Implementation Method 1
a stem having a first end and a second end, the first end of the stem to couple to the housing of the image generator and the second end of the stem to project from the image generator, the stem having a non-flexed position and a flexed position, at least a portion of the stem between the first end and the second end is to move relative to the housing of the image generator when the stem moves between the non-flexed position and the flexed position

AI summary
Methods, apparatus, and articles of manufacture are disclosed. An example head-worn display apparatus includes a frame to support a lens and a housing having an image generator. The housing couples the image generator to the frame and is to project an image adjacent the lens. The apparatus includes a stem having a first end and a second end. The first end of the stem is to couple to the housing of the image generator and the second end of the stem to project from the image generator. The stem has a non-flexed use position and a flexed use position, where at least a portion of the stem between the first end and the second end is to move relative to the housing of the image generator when the stem moves between the non-flexed position and the flexed position while a position of the image generator remains in a fixed relationship relative to the frame.
