Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cup attaching apparatuses for eyeglass lenses are inadequate for supporting both unprocessed and processed lenses, often interfering with imaging operations due to fixed support pin arrangements that are not adaptable to different lens shapes.

Innovation Solution

A cup attaching apparatus with a lens mount and a moving mechanism that adjusts the distance of support pins from the central axis to accommodate both unprocessed and processed lenses, allowing for flexible attachment and imaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If support pins are arranged in fixed positions suitable for unprocessed lenses, then unprocessed lenses can be supported properly, but processed lenses cannot be supported and imaging operations are interfered with

Engineering Contradiction:

Improveadaptability to different lens typesVSAvoidtrouble of replacing mount

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The support pins are made movable rather than fixed, allowing their positions to be dynamically adjusted. The moving mechanism enables the support pins to change their distance from the central axis, adapting to different lens types (unprocessed and processed) without requiring replacement of the entire mount.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The position parameters of the support pins are changed by the moving mechanism. By adjusting the distance of support pins from the central axis, the system can accommodate different lens types and avoid interference with imaging operations, eliminating the need to replace the mount.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If support pins are arranged for unprocessed lens support, then unprocessed lenses are supported correctly, but processed lenses cannot be supported

Engineering Contradiction:

Improvelens support reliabilityVSAvoidcompatibility with processed lenses

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The support pin positions are dynamically adjustable, allowing the system to maintain reliable support for unprocessed lenses while also adapting to support processed lenses with different geometries.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The moving mechanism enables the support pins to serve multiple functions by adjusting their positions, allowing the same mount to reliably support both unprocessed and processed lenses.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If support pins are in fixed positions, then the structure is simple, but imaging operations are interfered with

Engineering Contradiction:

Improvemount structure simplicityVSAvoidinterference with imaging

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The support pins can move to different positions, allowing them to be positioned out of the imaging path when needed, thereby eliminating interference with imaging operations while maintaining structural simplicity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The moving mechanism acts as an intermediary that allows the support pins to be dynamically positioned, enabling them to move out of the way during imaging operations without requiring a completely different mount structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A cup attaching apparatus for attaching a cup to an eyeglass lens, comprises: a lens mount on which the lens is to be mounted; at least three support pins provided on the lens mount to support the lens when a rear refractive surface of the lens is brought in contact with the support pins; and a first moving mechanism adapted to simultaneously move the support pins to change a distance of each support pin from a central axis for attachment of the cup.
