Contact Lens Package Elevating Mechanism for Easy Removal

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Soft contact lenses are difficult to remove from conventional blister packages due to their pliability, often folding or being hard to grasp, which complicates extraction.

Innovation Solution

The contact lens package incorporates an elevating mechanism, such as a mechanical deformation or foam that expands upon wetting, to lift the lens above the storage solution, facilitating easy removal by changing the package's shape when opened.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If soft contact lenses are packaged in conventional blister packages, then the lenses are protected and stored conveniently, but the lenses become difficult to remove due to their pliability

Engineering Contradiction:

Improveease of lens removalVSAvoidlens pliability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The package is pre-configured with an elevatable lens holder that automatically activates upon opening. The lens is positioned on this holder in advance, ready to be elevated when the package seal is broken, facilitating easy removal before the user even grasps the lens

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An elevatable lens holder serves as an intermediary mechanism between the lens and the user's hand. This mediator elevates the lens from the storage cavity, making it accessible and easier to grasp without direct manipulation of the soft lens itself

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If soft contact lenses are extracted from conventional packages, then the lenses can be used, but the lenses may fold on themselves during extraction

Engineering Contradiction:

Improveease of lens extractionVSAvoidlens folding

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The lens is pre-positioned on an elevatable holder that maintains its shape during extraction. By elevating the lens before removal, the system prevents the lens from folding during the extraction process, as the lens remains supported on the structured holder throughout the removal action

Inventive Principle:

Principle #10Preliminary action
