Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional packaging for windscreen wiper blades, particularly those made of cardboard, face issues such as being opaque, leading to increased damage from customer inspection, and requiring additional interior sleeves to prevent movement and damage, which increases costs and complexity.

Innovation Solution

A sleeve-type packaging made from cardboard, featuring laminated front and rear faces with assembly and closure flaps, allowing for easy fabrication and providing strength and resilience. This design forms a secure, hexagonal cross-section that retains the windscreen wiper blade without additional packaging elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cardboard packaging is used, then environmental friendliness and ease of manufacture are improved, but opacity causes customers to open packages for inspection increasing damage risk

Engineering Contradiction:

Improveease of manufactureVSAvoiddamage from customer inspection

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies transparency changes by incorporating a transparent or translucent window in the front face of the cardboard packaging, allowing customers to view the wiper blade without opening the package, thus preventing damage while maintaining the environmental benefits of cardboard material

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The packaging is segmented into distinct functional areas including a front face with viewing window, rear face, assembly flap, and lamination tabs, allowing each section to serve its specific purpose while maintaining overall structural integrity

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If conventional cardboard packaging is used, then environmental friendliness is improved, but additional interior sleeves are required to prevent wiper blade movement and damage

Engineering Contradiction:

Improveprotection from damageVSAvoidpackaging structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the protective function and structural support function into the main cardboard packaging body itself through features like the assembly flap that secures the wiper blade and lamination tabs that provide rigidity, eliminating the need for separate interior protective sleeves

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The assembly flap serves multiple functions: it closes the packaging, secures the wiper blade in place through attachment to the rear face, and provides structural support, replacing the need for multiple separate protective components

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If plastic tubular packaging is used, then product protection and display capability are improved, but environmental friendliness and ease of manufacture deteriorate

Engineering Contradiction:

Improveproduct protectionVSAvoidease of manufacture

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent changes the material parameter from plastic to cardboard, and modifies the structural parameters by adding specific features like lamination tabs and assembly flaps to cardboard, achieving comparable protective functionality while improving environmental friendliness and ease of manufacture

Inventive Principle:

Principle #35Parameter changes
