Solution Overview

Problem

Conventional ophthalmic lens packages, such as blister packs, often cause users difficulty in accessing the lenses without damaging them, as the lenses can stick to the laminate and are prone to loss during opening.

Innovation Solution

A package design featuring pivotally attached side members and a pouch with breakable sides, allowing easy opening to present the lens while containing the solution, which is sealed to prevent loss and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional blister packs with rigid receptacles and laminate covers are used, then the package provides secure storage and shipping protection, but users have difficulty removing the lens without damaging it and lenses may stick to the inner surface and be damaged or lost during opening

Engineering Contradiction:
Improveease of lens removalVSAvoidlens integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The package is divided into separate functional components: a rigid outer receptacle for structural support and a separate flexible pouch member for lens containment. The pouch member can be easily separated from the receptacle, allowing users to access the lens without manipulating the rigid laminate structure that causes sticking and damage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pouch member is made from flexible material that can conform to the lens shape and be easily manipulated. This flexible pouch can be removed from the rigid receptacle and opened without causing the lens to stick to hard surfaces, thereby preventing damage during the removal process.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If the pouch member is easily separable from the receptacle, then users can access the lens without damage, but the package structure becomes more complex

Engineering Contradiction:
Improveease of package openingVSAvoidpackage structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The package uses segmentation to separate the receptacle and pouch member into distinct components. This separation allows for simple attachment and detachment mechanisms rather than complex integrated structures, actually reducing the perceived complexity while improving ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pouch member is designed with dynamic attachment characteristics, allowing it to be easily separated from the receptacle when needed. This dynamic design enables simple opening without requiring complex mechanisms, maintaining structural simplicity while improving user accessibility.

Inventive Principle:
Principle #15Dynamics
