Removable Light Seal With Vision Correction Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, such as head-mounted devices, face challenges in customizing display and lens configurations to accommodate different user interpupillary distances and vision corrections, leading to discomfort and ineffective image presentation.
Innovation Solution
A head-mounted device with adjustable optical assemblies and a custom-fit removable light seal that includes vision correction lenses, where motors or cooperative mechanical structures adjust the spacing between optical assemblies based on user-specific interpupillary distance information, ensuring precise alignment and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed optical assembly spacing is used, then device structure is simple, but it cannot accommodate different user interpupillary distances
Solution Approach 1:
The patent implements dynamic adjustability of the optical assemblies through motors that can change the spacing between assemblies based on detected interpupillary distance, transforming a static structure into a dynamically adaptable one
Solution Approach 2:
The system uses sensors or wireless transceivers to detect interpupillary distance information and feeds this data back to the motor control system, which then automatically adjusts the optical assembly spacing to match the user's specific measurement
2Adaptability or versatility
If removable light seal with vision correction lenses is added, then vision correction capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the head-mounted device into separable components, including a removable light seal portion that can be detached and replaced, allowing vision correction lenses to be integrated in a modular fashion
Solution Approach 2:
The removable light seal serves multiple functions: it provides vision correction through customized lenses, maintains the light seal function to block stray light, and enables customization for different users without requiring separate devices
3Measurement precision
If motorized adjustment system is implemented, then interpupillary distance accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system automatically detects interpupillary distance and self-adjusts the optical assembly spacing without requiring manual intervention, with the sensor and motor working together in an automated feedback loop

AI summary
A head-mounted device may include optical assemblies for presenting images to a user. Motors may be used to adjust the spacing between the optical assemblies to accommodate different interpupillary distances. The head-mounted device may have a housing that receives a custom-fit removable light seal with vision correction lenses. A sensor or wireless transceiver in the housing may receive interpupillary distance information from the light seal. Based on this information, the motors may adjust the optical assemblies so that the optical assemblies are spaced apart by an amount that matches the interpupillary distance associated with the user of the custom-fit removable light seal.
