Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted devices lack efficient mechanisms for accommodating user-specific vision correction needs and secure, wireless communication with removable lenses.
Innovation Solution
Incorporation of near-field communications antennas in both the head-mounted device and removable vision correction lenses, allowing for secure data exchange and adjustment of display content based on user-specific vision correction information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If near-field communications antennas are incorporated in removable vision correction lenses, then wireless communication capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the communication system into separate segments: the vision correction lens contains its own near-field communication antenna and can communicate wirelessly with the head-mounted device. This segmentation allows the lens to be independently configurable and adaptable while maintaining a relatively simple overall system architecture where each component performs a specific function.
2Adaptability or versatility
If vision correction information is stored and transmitted in the vision correction lenses, then user-specific customization is improved, but information security requirements increase
Solution Approach 1:
The patent introduces the head-mounted device as an intermediary between the vision correction lens and the user/environment. The lens transmits vision correction information wirelessly to the head-mounted device, which then processes and uses this information to customize the display. This intermediary architecture enables secure information handling and processing while maintaining user-specific customization capabilities.

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 secure, wireless communication for user-specific adjustments to display content, enhancing user experience by accommodating individual vision needs and improving device functionality.
Implementation Method 1
The antennas may be formed from coils that surround corrective lens elements in the vision correction lenses. In the head-mounted device, antennas may be formed from coils surrounding the lenses in the optical modules and/or may include other coil(s).
Data Source
AI summary
A head-mounted device may have a head-mounted housing. The head-mounted housing may have displays that display images for a user through lenses. The displays and lenses may be mounted in left and right optical modules. Attachment structures such as magnets may be used to removably attach left and right vision correction lenses to the left and right optical modules, respectively. The images may be viewed from eye boxes through the vision correction lenses while the head-mounted device is being worn by the user. The vision correction lenses and the head-mounted device may be provided with near-field communications antennas. The antennas may be formed from coils that surround corrective lens elements in the vision correction lenses. In the head-mounted device, antennas may be formed from coils surrounding the lenses in the optical modules and/or may include other coil(s).
