Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mountable devices require adjustments to accommodate different facial features and vision needs, as existing devices often lack modular fit adjustment capabilities and vision correction options, leading to inconsistent user experiences.
Innovation Solution
The integration of modular lens assemblies that can be coupled to the head-mountable device, allowing for adjustable positioning and orientation, including interchangeable lenses for vision correction, to accommodate various facial shapes and vision requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If head-mountable devices use fixed lens assemblies, then device structure is simple, but user comfort and fit consistency deteriorate across different facial features
Solution Approach 1:
The lens assembly is divided into separate modular components including interchangeable lens elements and adjustable mounting mechanisms. This segmentation allows individual components to be adjusted or replaced independently, enabling fit customization without redesigning the entire assembly, thus resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The lens assembly incorporates adjustable and movable elements that can be dynamically reconfigured to match different facial geometries. This dynamic capability allows the same device to adapt to various users through simple adjustments rather than requiring multiple fixed-size devices, improving adaptability while maintaining reasonable structural complexity.
2Adaptability or versatility
If head-mountable devices use standardized lens assemblies, then manufacturing cost is low, but vision correction effectiveness deteriorates for users with specific vision needs
Solution Approach 1:
Vision correction lenses are provided as separate interchangeable elements that can be manufactured using standard processes and then assembled into the modular lens assembly. This approach maintains manufacturing simplicity while enabling customization for different vision requirements, as lenses can be produced in standard configurations and then swapped based on user needs.
Solution Approach 2:
The lens assembly design provides universal compatibility across different vision correction needs through a standardized interface that accommodates various lens types. A single mounting mechanism can hold multiple lens elements designed for different prescriptions, making the system universally applicable to various vision requirements without requiring custom manufacturing for each case.
3Adaptability or versatility
If head-mountable devices are designed for specific face shapes, then fit precision is high, but device versatility deteriorates across different users
Solution Approach 1:
The lens assembly includes adjustable mounting mechanisms that can be dynamically repositioned to achieve precise alignment with the user's eyes regardless of facial geometry. This dynamic adjustment capability allows the same device to maintain high alignment precision across different face shapes by enabling real-time customization of lens position and orientation.
