Solution Overview

Problem

Conventional packaging for glass lenses, particularly those with hydrophobic coatings and imprints, faces issues with abrasion due to movement and high material costs associated with complete fleece lining, which complicates recyclability.

Innovation Solution

A packaging design featuring pivotable sections with a protective element attached to one section, allowing the glass body to be positioned without initial contact, then securely engaging to prevent abrasion and reduce material usage by minimizing the protective element's size and attachment points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the inside of the packaging is completely lined with an abrasion-reducing fleece, then the glass body surface is protected from scratching, but the material cost increases and recyclability becomes more difficult

Engineering Contradiction:
Improveabrasion protectionVSAvoidmaterial cost and recyclability
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The packaging is divided into a first packaging section and a second packaging section that can pivot relative to each other. The protective element is attached only to the second packaging section, segmenting the protection function from the entire packaging structure to only where needed during transport.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of providing uniform protection across the entire packaging interior, the protective element is localized to specific areas where glass bodies are most vulnerable during transport. The protective element is positioned to contact only the regions of the glass body that require protection during the closed position.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If a protective element is attached to the packaging, then abrasion is prevented, but the device complexity and material usage increase

Engineering Contradiction:
Improvesurface scratchingVSAvoidprotective element attachment
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protective element's engagement with the glass body is dynamic rather than static. When the packaging is in the open position, the protective element is separated from the first packaging section by distance d, allowing easy insertion and removal of glass bodies without contact. When closed, the sections pivot and the protective element engages to provide protection only during transport.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The protective element is designed as a simple, inexpensive component that can be easily attached and detached. It is positioned at the edge of the second packaging section, minimizing material usage while providing sufficient protection for the intended transport function.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Object-affected harmful factors

If the protective element is positioned close to the first packaging section, then protection is effective, but the glass body may contact the protective element during insertion

Engineering Contradiction:
Improveabrasion preventionVSAvoidglass body insertion
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The distance d between the protective element and the first packaging section is variable, being larger in the open position to facilitate easy insertion of glass bodies without contact, and smaller in the closed position to provide effective protection during transport.

Inventive Principle:
Principle #15Dynamics

AI summary

The package (1) has a protective element (19) fastened at a package section (7) such that the protective element is turned towards another package section (5) in an open position of the package and arranged at a preset distance from the latter package section. The package is transferred from the open position into a closed position by pivoting the latter package section to the former package section at a pivot axis (s1). The distance between the protective element and the latter section in the closed position is smaller than in the open position. The sections are made of paper or plastic.
