Custom Corrective Clip Ordering for HMDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for ordering and manufacturing corrective lenses for head-mounted displays (HMDs) lack efficiency and convenience, as they often require in-person visits to eye care professionals and do not allow direct, user-driven determination of the need for corrective lenses or automatic calculation of prescriptions.
Innovation Solution
A method that enables consumers to directly order and receive custom prescription corrective clips for HMDs by providing ordering information, allowing self-assessment or assistance from an eye care professional, and shipping the clips directly to customers, with options for online ordering and automatic prescription calculation, using a standard clip design that adjusts for pupillary distance and near vision modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If consumers visit eye care professionals for in-person fittings and prescription confirmation, then prescription accuracy and reliability are improved, but convenience and time efficiency deteriorate
Solution Approach 1:
The system enables consumers to self-assess their need for corrective lenses by providing interactive ordering information and tools that allow them to determine eligibility without requiring in-person visits to eye care professionals, thereby improving convenience while maintaining prescription accuracy through automated calculations
Solution Approach 2:
The patent introduces an intermediary ordering system that mediates between consumers and eye care professionals, allowing consumers to complete prescription calculations and lens ordering online while still providing an option to visit ECPs for confirmation, thus resolving the contradiction between accessibility and reliability
2Productivity
If automated prescription calculation systems are implemented, then convenience and ordering speed are improved, but measurement precision and prescription accuracy may deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms where consumers can review their automated prescription calculations and SV/PD measurements before finalizing the order, allowing them to verify accuracy and correct any errors, thus maintaining measurement precision while enjoying the speed benefits of automated calculation
Solution Approach 2:
The patent performs preliminary measurements and calculations automatically during the ordering process, but still requires consumer input and verification before final prescription generation, ensuring that automated speed does not compromise the precision of the final prescription
3Ease of operation
If direct online ordering without ECP involvement is allowed, then ease of operation and accessibility are improved, but reliability and prescription validity may worsen
Solution Approach 1:
The ordering system is designed to serve multiple functions: it provides self-service ordering for convenience, automated prescription calculation for speed, and maintains reliability by allowing consumers to choose whether to proceed with automated prescriptions or visit ECPs for confirmation, thus accommodating different user needs without compromising any single aspect
4Productivity
If custom prescription lenses are manufactured and shipped directly to consumers, then productivity and convenience are improved, but manufacturing complexity and quality control requirements increase
Solution Approach 1:
The patent standardizes prescription parameters into SV (spherical equivalent) and PD (pupillary distance) measurements that can be automatically processed and transmitted to manufacturers, simplifying the manufacturing process by using standardized parameters rather than complex individual lens specifications, thus enabling direct-to-consumer delivery without excessive manufacturing complexity

AI summary
A method for ordering a corrective clip having corrective lenses. The clip corrects a wearer's view of a head mounted video display. When customers purchase an HMD, they are provided with clip ordering information. This includes information allowing the users to determine if a clip is required for their personal use. By providing at least SV and PD data customers can place their own orders which are transmitted to the lab. The completed corrective clip is delivered directly to the customer. Since the clip mounts on the viewer, a fitting session is not required. In use, the corrective clip reside between the user's eyes and an PDVID display, without contacting the user.
