Solution Overview

Problem

Existing packaging solutions for eyeglass lenses do not adequately address the need for precise location and protection of lenses with different shapes and thicknesses, particularly during transportation, which can lead to damage due to improper positioning.

Innovation Solution

A packaging system comprising a bottom panel, box-sections with articulations, and flaps that can be raised to accommodate lenses of varying diameters, utilizing locating tongues to securely position and protect eyeglass lenses by allowing modulation of retaining means, facilitating cost-effective production and use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single packaging design is used for all lens types, then manufacturing cost is reduced, but locating precision for different lens shapes and thicknesses deteriorates

Engineering Contradiction:

Improvemanufacturing costVSAvoidlocating precision

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The packaging is divided into multiple adjustable retaining means including flaps and positioning elements that can be independently adjusted to match different lens dimensions, allowing a single packaging design to accommodate various lens shapes and thicknesses with precise locating

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The packaging incorporates movable flaps and adjustable retaining means that can be dynamically repositioned according to the specific lens being packaged, enabling the same packaging to adapt to different lens configurations while maintaining precise locating accuracy

Inventive Principle:

Principle #15Dynamics

2Manufacturing precision

If multiple stock packaging types are used for different lens types, then locating precision is improved, but device complexity and inventory requirements increase

Engineering Contradiction:

Improvelocating precisionVSAvoidpackaging variety

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The packaging design integrates multiple functions into a single structure, with adjustable flaps and retaining means that can be configured for different lens types, eliminating the need for multiple specialized packaging designs while maintaining precise locating capabilities across all lens variations

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If rigid packaging structures are used, then protection during transportation is improved, but adaptability to different lens shapes deteriorates

Engineering Contradiction:

Improveprotection capabilityVSAvoidadaptability to different shapes

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The packaging employs flexible flaps and adjustable retaining means that can conform to different lens shapes and thicknesses, providing customized protection for each lens type while maintaining the structural integrity needed for safe transportation

Inventive Principle:

Principle #30Flexible shells and thin films
