Optical Equipment Ordering Method for Accurate Visual Representation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online spectacle fitting systems have a low satisfaction rate as wearers may not accurately visualize how a selected spectacle frame would look on them, leading to dissatisfaction when trying on the actual equipment.
Innovation Solution
A method that determines accurate mounting data by considering wearer and optical equipment data, including geometrical and dynamic information, to provide a precise visual representation of the spectacle frame when worn, allowing for modifications based on wearer feedback and opinion, and incorporating optical lens data for customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple digital image fitting system is used, then the system complexity is reduced and ease of operation is improved, but the accuracy of visual representation deteriorates leading to low wearer satisfaction
Solution Approach 1:
The fitting system is segmented into multiple independent modules: image capture module, 3D reconstruction module, virtual try-on module, and feedback module. Each module handles a specific aspect of the fitting process, allowing the system to maintain simplicity in user interaction while achieving high accuracy through specialized processing in each segment.
Solution Approach 2:
The system transitions from 2D digital images to 3D reconstructed models of the wearer's face and head. This dimensional enhancement allows for much more accurate visual representation of how spectacles will look when worn, while the automated 3D reconstruction process maintains ease of operation by eliminating manual measurement requirements.
2Device complexity
If mounting data is determined without considering wearer and optical equipment data, then the ordering process is simplified, but the accuracy of mounting data deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically capturing wearer data through imaging and pre-determining mounting parameters based on the optical equipment data and wearer characteristics. This preliminary processing occurs before the actual ordering decision, allowing the system to integrate multiple data sources accurately while keeping the user-facing ordering process simple and straightforward.
3Productivity
If the wearer cannot try on the selected spectacle frame before ordering, then the ordering process speed is improved, but the reliability of the ordering decision deteriorates
Solution Approach 1:
The system creates a virtual copy of the spectacle frame and places it onto a 3D reconstructed model of the wearer's face. This virtual try-on copy allows the wearer to see exactly how the spectacles will look and fit before ordering, maintaining fast ordering speeds while significantly improving the reliability of the ordering decision through accurate visual feedback.
Solution Approach 2:
The system implements a feedback loop where the virtual try-on results are immediately displayed to the wearer, allowing them to assess the appearance and make informed decisions. The system can also capture wearer responses and adjust recommendations accordingly, maintaining quick turnaround while improving decision reliability through iterative feedback.
