Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The diversification of spectacle frames without proper knowledge of material and shape constraints leads to the production of lower quality frames, making it difficult to use conventional industrial processing for ophthalmic lenses, resulting in delays and customer dissatisfaction.
Innovation Solution
A method to verify compliance with predetermined criteria for spectacle frames, categorizing them based on geometric, mechanical, and structural characteristics to determine suitable industrial processes, ensuring compatibility with ophthalmic lenses and standard manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If companies manufacture spectacle frames without full knowledge of material and shape constraints, then the diversification of spectacle frame offer increases, but the quality of frames deteriorates and conventional industrial processing cannot be used
Solution Approach 1:
The patent implements preliminary verification of frame compliance with predetermined criteria before the lens cutting and assembly process. The system checks geometric, mechanical, and structural characteristics of frames against required specifications, and detects frames requiring special techniques or impossible lens fitting before production begins, preventing processing errors and ensuring only compatible frames proceed to manufacturing
Solution Approach 2:
The patent introduces an intermediary verification system that acts as a mediator between frame manufacturing and lens assembly processes. This system includes devices to acquire geometric characteristics, verify mechanical properties, and assess structural integrity, serving as a bridge that ensures compatibility between frames and standard industrial processing capabilities
2Reliability
If special techniques are required for cutting and assembly of ophthalmic lenses, then frame compatibility is maintained, but manual intervention is required and production time increases
Solution Approach 1:
The system performs preliminary detection of frames requiring special techniques or impossible lens fitting before the ordering process, allowing customers to make informed choices and preventing delays during production. Frames are categorized and flagged in advance, so that only compatible frames with standard processing requirements proceed to automated manufacturing
3Measurement precision
If detection of non-compliant frames is performed late in the process, then frame quality issues are identified, but manufacturing delays occur and customer satisfaction decreases
Solution Approach 1:
The patent implements detection of frame compliance issues before the ordering process and before any manufacturing operations begin. The system acquires geometric characteristics, verifies mechanical properties, and assesses structural characteristics of frames in advance, categorizing them according to their compatibility with standard industrial processing. This preliminary verification prevents any frames requiring special techniques or impossible lens fitting from entering the production flow, eliminating delays and allowing customers to make informed choices about their frame selections

AI summary
The invention relates to a method for verifying conformity with a predetermined criterion of use of a spectacle frame intended to receive two ophthalmic lenses, wherein the following steps are carried out: a) at least one geometric and/or mechanical and/or structural characteristic of this spectacle frame is determined and the spectacle-frame category to which said spectacle frame belongs is deduced therefrom from a set of predetermined spectacle-frame categories; b) an outline of at least one of said ophthalmic lenses intended to be mounted in said spectacle frame or of a rim of this spectacle frame is determined in two or three dimensions; c) the value of each parameter of a list of parameters of said spectacle frame is evaluated, this list being determined depending on said spectacle-frame category determined in step a); and the value of at least some of said parameters being evaluated depending on said outline determined in step b), d), from the values of said parameters of the spectacle frame i.e. the values determined in step c), the conformity of the spectacle frame to the predetermined criterion is deduced.
