Solution Overview

Problem

The existing process of measuring spectacle frames for precise lens fitting is inefficient when the final frame chosen by the wearer is not available, leading to delays and errors due to manual data transmission and measurement discrepancies between optician premises and measuring rooms.

Innovation Solution

A method and system where measurements taken on the wearer are stored in a first computer entity, sent to a server, and then used to measure and order lenses for a frame of the same model and size at a second location, with the server coordinating and centralizing all data for accurate lens production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual data transmission is used between optician premise and measuring room, then the process can be completed, but delays and errors occur

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidorder processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of writing down and transmitting frame model data with an automated optical scanning system. The 3D scanner captures the actual frame geometry and transmits it digitally, eliminating manual data entry and transmission delays while improving accuracy through direct digital measurement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a digital copy of the physical frame by scanning its 3D geometry. This digital replica contains all necessary measurement data and can be transmitted instantly to the measuring room, replacing the need for physical frame transport and manual data transcription.

Inventive Principle:
Principle #26Copying

2Productivity

If measurements are performed on an available frame instead of the final frame, then the process can continue, but measurement discrepancies occur

Engineering Contradiction:
Improveorder processing efficiencyVSAvoidlens fitting accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent replaces manual measurement methods with automated 3D optical scanning. This eliminates human error in measuring and recording frame parameters, ensuring that the digital model accurately represents the physical frame's geometry for precise lens manufacturing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The frame itself provides its measurement data through the scanning process. The 3D scanner automatically captures all necessary geometric parameters without requiring manual measurement by an operator, reducing human intervention and potential errors.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the exact frame is not available, then the wearer can still choose a frame model, but the final frame may have different features

Engineering Contradiction:
Improveframe selection flexibilityVSAvoidlens frame matching accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent creates a digital copy of the actual frame through 3D scanning. This digital replica preserves the exact geometric features of the physical frame, allowing accurate lens design and manufacturing even when the frame is not physically present during the ordering process.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent performs the 3D scanning and creates the digital frame model in advance, before the lens manufacturing process begins. This preliminary capture of frame geometry ensures that all measurement data is available and locked in, preventing any discrepancies from arising during subsequent processing.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to a method and a computer system and its components for providing a spectacle frame adapted to a future wearer. The method comprises the steps of: - storing in a memory of a server (SER) a first set of data (F1) related to measurements performed on the wearer, in correspondence to a first identifier (ID1), and - storing in the memory of said server (SER) a second set of data (F2) related to measurements performed on the frame to provide, in correspondence to a second identifier (ID2). The server (SER), upon reception of a piece of information (DOC2) indicating an association between the first and second identifiers, is arranged for compiling a computer document (ORD(ID1-ID2)) including at least a part of the first and second sets of data for enabling the edition of an order form.
