Augmented Reality Eyewear With Adjustable Temple Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays for medical interventions cause wearer fatigue and discomfort due to uneven weight distribution and pressure points, limiting their usability for extended periods.
Innovation Solution
A head-mounted display device with adjustable straps and temple housings, a see-through display assembly with adjustable tilt angles, and detachable lens assemblies, designed to distribute weight more evenly and allow for customizable fit and comfort, including features like a pantoscopic tilting assembly and detachable lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If head-mounted display uses fixed weight distribution structure, then device structure is simple, but wearer experiences fatigue and discomfort during extended use
Solution Approach 1:
The patent implements dynamic weight distribution through adjustable temple arms that can be positioned at multiple locations along their length. The temple arms include adjustment mechanisms allowing them to be moved between different positions to redistribute weight away from the nose and forehead, adapting the weight distribution to different wearers' anatomical features and comfort preferences.
Solution Approach 2:
The head-mounted display is segmented into modular components including adjustable temple arms, repositionable display units, and separate lens assemblies. This segmentation allows independent adjustment of each component to optimize overall comfort and fit for the wearer.
2Ease of operation
If head-mounted display has fixed pressure distribution, then device structure is simple, but creates pressure points on wearer's face
Solution Approach 1:
The temple arms are designed with dynamic adjustability, allowing them to be repositioned along their length to change the contact points and pressure distribution on the wearer's face. This dynamic repositioning capability enables the system to adapt to different facial geometries and reduce concentrated pressure points.
Solution Approach 2:
The patent applies local quality by providing specific adjustment mechanisms at particular locations on the temple arms, allowing localized modification of pressure distribution at key contact points on the wearer's face while maintaining simplicity in other areas.
3Adaptability or versatility
If head-mounted display is not adjustable, then device structure is simple, but cannot accommodate different wearer preferences and anatomical features
Solution Approach 1:
The head-mounted display incorporates dynamic adjustability in multiple components including temple arms that can be repositioned, display units that can be independently adjusted, and lens assemblies that can be customized. These dynamic adjustment capabilities enable the system to adapt to different wearers' anatomical features and preferences.
Solution Approach 2:
The adjustable mechanisms are designed to serve multiple functions: accommodating different head sizes, adjusting for specific anatomical features, customizing weight distribution, and adapting to different usage scenarios. This multi-functionality is achieved through integrated adjustment mechanisms that provide versatile customization capabilities.
4Adaptability or versatility
If display tilt angle is fixed, then device structure is simple, but cannot accommodate different wearer anatomical features and viewing preferences
Solution Approach 1:
The display units are equipped with adjustable tilt mechanisms that allow them to be positioned at different angles relative to the wearer's face. This dynamic adjustability enables optimization of viewing angles for different anatomical features and viewing preferences while maintaining a relatively simple overall structure through modular design.
