Detachable Module for 360-Degree Face Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image recording and adjustment systems for spectacle fitting are limited by their inflexibility, high space requirements, and costs, and they often necessitate separate devices for scanning people and objects, which is inefficient and costly.
Innovation Solution
An image recording system with a detachable additional module that expands the viewing angle range from 240° to 360°, allowing for the capture of both facial and object data, including eyeglass frames, using a rotatable or slidable holder and optional supplemental lighting, integrated with a centering system for determining centering parameters for spectacle lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate devices are used for scanning people and objects, then measurement precision is improved, but device complexity increases and cost rises
Solution Approach 1:
The patent combines face scanning cameras and object scanning cameras into a single integrated image acquisition system. The multiple camera modules are mounted on a common support structure with shared lighting and control systems, allowing both facial features and spectacle frames to be scanned using one unified device rather than separate scanners.
Solution Approach 2:
The image acquisition system is designed with multi-functionality to perform both face scanning and object scanning tasks. The camera modules and lighting system can be configured and controlled to capture facial geometry for virtual try-on or to scan spectacle frames for centering parameters, making a single device serve multiple purposes.
2Measurement precision
If multiple separate scanning devices are deployed, then measurement precision is improved, but space requirements increase
Solution Approach 1:
The patent merges face scanning and object scanning functionalities into one compact integrated system. Multiple camera modules are arranged on a shared support structure with common lighting and control electronics, significantly reducing the space required compared to having separate dedicated scanners for each function.
3Device complexity
If a fixed camera arrangement is used, then device complexity is reduced, but adaptability decreases
Solution Approach 1:
The patent incorporates movable and adjustable camera modules that can be positioned and oriented differently to accommodate various scanning needs. The camera modules can be adjusted to capture facial features from different angles or to scan objects of varying sizes and shapes, providing dynamic adaptability while maintaining a relatively simple overall system structure.
