Supplemental Lens Mounting for Vision-Corrected Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted devices struggle to accommodate users with visual defects such as myopia, hyperopia, or astigmatism, as their optical systems often fail to provide clear focus on displayed content.
Innovation Solution
A head-mounted device with a non-removable lens system that supports removable supplemental lenses, which can be magnetically coupled and adjusted to correct for individual visual defects, using stored information like eyeglass prescriptions and optical characteristics to customize the display for each user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed optical system with non-removable lenses is used in head-mounted devices, then the device structure is simple and manufacturing is easy, but users with visual defects cannot focus properly on displayed content
Solution Approach 1:
The optical system is divided into two separate lens components: a fixed non-removable lens and a removable supplemental lens. This segmentation allows the device to maintain a simple base structure while enabling customization through the addition of corrective lenses for users with visual defects.
Solution Approach 2:
The optical system transitions from a static fixed lens configuration to a dynamic configurable system where supplemental lenses can be added or removed based on the user's visual needs, allowing the device to adapt to different users without redesigning the entire optical system.
2Reliability
If custom lenses are manufactured for each user's specific visual prescription, then visual clarity is improved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The lens system is segmented into a standardized base lens that is mass-producible and a customizable supplemental lens component. This allows the majority of the optical system to be manufactured efficiently while only the supplemental portion requires customization for each user's prescription.
Solution Approach 2:
The supplemental lens component is designed with a universal interface and standardized mounting mechanism that can accommodate different optical prescriptions. This universal design allows a single lens holder structure to serve multiple users with different visual needs, reducing manufacturing complexity while maintaining customization capability.
3Adaptability or versatility
If removable supplemental lenses are added to accommodate different users, then adaptability to individual visual needs is improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The lens system allows dynamic reconfiguration by enabling users to remove and install supplemental lenses as needed. The magnetic coupling mechanism provides a simple, tool-free method for users to change lenses, maintaining ease of operation while achieving adaptability to different visual prescriptions.
Solution Approach 2:
A magnetic coupling mechanism serves as an intermediary between the lens holder and supplemental lenses, providing automatic alignment and secure attachment. This intermediary simplifies the user interaction by eliminating the need for complex alignment procedures or specialized tools, making lens changes intuitive and easy.
4Ease of operation
If magnetic coupling structures are used to attach supplemental lenses, then ease of installation is improved, but reliability of lens attachment may be compromised
Solution Approach 1:
The magnetic coupling acts as an intermediary attachment mechanism that balances ease of installation with secure retention. The magnetic force provides sufficient holding strength to keep lenses firmly in place during normal use while allowing simple removal when needed, achieving both operational ease and attachment reliability.

Implementation Method 1
Magnetic coupling structures or other engagement structures may be used to removably couple the supplemental lens system to the head-mounted device
Implementation Method 2
This information be stored in the removable supplemental lens system using bar codes or other optically readable patterns, programmable memory, or other data storage. A memory reader, gaze tracking system, or other sensor may be used in retrieving the stored information.

AI summary
A head-mounted device may have a display that displays content for a user. Head- mounted support structures in the device support the device on the head of the user. A non- removable lens system may be supported by the head-mounted support structures. The head- mounted support structures may be configured to receive a removable supplemental lens system. The removable supplemental lens system may be used to customize the head- mounted display to accommodate the user's vision. Information such as information on the optical characteristics of the removable supplemental lens system and the user' s eyeglass prescription may be stored in the removable supplemental lens system using bar codes, text, programmable memory, or other data storage. When the removable supplemental lens system is installed in the head-mounted device, control circuitry in the head-mounted device may retrieve the stored information. A gaze tracker system or other sensors may be used in retrieving the stored information.
