Dispensing System for Head-Mountable Vision Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mountable devices lack an efficient system for determining and providing appropriate corrective lenses for users with varying vision needs, limiting their ability to properly view visual outputs.
Innovation Solution
A dispensing system that includes an input station for determining the user's vision requirements, a dispenser for providing sample lens sets, and a point-of-sale station for purchasing appropriate lenses, allowing users to sample and purchase lenses that match their specific needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If head-mountable devices are designed without integrated lens dispensing functionality, then device complexity is reduced and manufacturing is easier, but users cannot efficiently determine and acquire appropriate corrective lenses for their vision needs
Solution Approach 1:
The lens dispensing system is divided into separate functional modules: an input station for determining vision requirements, a dispenser for providing sample lenses, and a point-of-sale station for purchasing. This segmentation allows the head-mountable device to offer comprehensive lens dispensing services while maintaining manageable complexity through modular architecture.
2Ease of operation
If a complete lens dispensing system is integrated into the head-mountable device, then users can efficiently determine and acquire appropriate corrective lenses, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The head-mountable device serves multiple functions: it acts as a vision testing device, a lens dispenser, and a point-of-sale system. By integrating these diverse functions into a single platform, the system enables complete lens dispensing operations while leveraging shared hardware and software resources to manage manufacturing complexity.
Solution Approach 2:
The lens dispensing system is nested within the head-mountable device framework. The input station, dispenser, and point-of-sale components are integrated as functional modules within the overall device architecture, allowing them to share common resources such as processing power, memory, and user interface elements.
3Measurement precision
If sample lens sets are provided for user testing, then users can accurately determine their vision needs and select appropriate corrective lenses, but the quantity of lens inventory required increases
Solution Approach 1:
The system provides sample lens sets with varying optical parameters (such as diopter strength and lens type) to enable users to test different vision correction options. By offering a focused range of parameter variations rather than complete lens inventories, the system achieves accurate vision assessment while managing inventory requirements.

AI summary
Different users of head-mountable devices have different needs for vision correction. A system can be provided to determine the corrective lenses that are most appropriate for a given user. A dispenser can contain a variety of different lenses that provide different types of vision correction. The dispenser can provide an appropriate one of the lenses, and a user can use the lens with a head-mountable device during a sampling session. During the sampling session, the user can verify that the lens is satisfactory.
