Retention Member for Head-Mounted Lens System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal video or image displays, such as head-mounted and heads-up displays, often obstruct the wearer's vision outside the screen, lack comfort and flexibility, and may not accommodate individuals with ocular disorders or corrective lenses, potentially causing vision difficulties and UV exposure risks.
Innovation Solution
A lens system with a retention member featuring a convexly curved lens mounting surface and channel design for secure attachment to a head-wearable device, allowing for removable lenses that provide protection and correction, and integration with a display system that maintains visibility of surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If head-mounted displays are used to present images, then image display functionality is achieved, but the wearer's vision outside the screen is obstructed
Solution Approach 1:
The display system is segmented into separate functional zones: a transparent display region for presenting images and a clear peripheral region for viewing surroundings. This segmentation allows simultaneous image display and environmental visibility without mutual interference.
Solution Approach 2:
Different optical properties are applied to different regions of the display: the central display area uses transparent materials with specific optical characteristics for image presentation, while the peripheral areas maintain high transparency for unobstructed viewing of the environment.
2Ease of operation
If conventional displays are used, then passive reception and presentation of information is achieved, but adaptability for persons with ocular diseases or corrective lenses is limited
Solution Approach 1:
The display device is designed with universal compatibility features, including adjustable optical parameters and interchangeable lens elements, enabling it to function effectively for users with various ocular conditions, whether they wear corrective lenses or not. The system can adapt to different visual requirements.
Solution Approach 2:
The display system incorporates dynamic adjustment capabilities, allowing optical properties such as focal length, magnification, and field of view to be modified in real-time to accommodate different users and their specific ocular requirements, making the device adaptable rather than static.
3Ease of manufacture
If head-mounted displays are used, then image presentation is achieved, but comfort and flexibility are limited
Solution Approach 1:
The display incorporates flexible transparent materials and thin-film structures that can conform to the user's head and face contours, providing a comfortable fit. The flexible nature of these materials allows for adjustable positioning and reduced pressure points, enhancing wearability.
Solution Approach 2:
The display transitions from a rigid, fixed-structure approach to a multi-dimensional flexible configuration that can adapt to different head shapes and sizes. The flexible materials enable the display to bend and conform in multiple directions, improving comfort without sacrificing functionality.

AI summary
According to aspects of the disclosure, a lens system may include lenses and a retention member. The lenses may be removably secured to a lens mounting surface of the retention member by one or more fixation elements. The retention member may also include a channel to receive a headband portion of a head wearable device.
