Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing packaging systems for rolled-up sheet material require unboxing and manual handling, which is inconvenient and prone to contamination and entanglement of sheet material strips.

Innovation Solution

A packaging system with a packaging box featuring mechanically weakened portions on both faces, allowing a mandrel to pass through and support the reel, enabling processing while the sheet material remains inside the packaging box.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the reel is removed from protective packaging before processing, then the sheet material can be accessed and processed, but the handling becomes inconvenient and contamination risk increases

Engineering Contradiction:

Improveease of reel installationVSAvoidcontamination of sheet material

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The reel is nested within the packaging box, which itself is mounted on the mandrel. The packaging box acts as an intermediate container that travels with the reel from storage to processing position, eliminating the need to remove the reel from its protective packaging before installation.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The packaging box serves as an intermediary between the reel and the processing apparatus. Instead of mounting the reel directly to the mandrel, the box is mounted first, and the reel remains contained within it during processing, reducing direct handling and contamination risk.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the reel is unboxed before processing, then the sheet material is accessible, but manual handling becomes cumbersome and time-consuming

Engineering Contradiction:

Improveinstallation speedVSAvoidease of reel handling

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The packaging box and reel are treated as a single integrated unit for mounting purposes. The box is designed with mounting features that allow it to be attached to the mandrel along with the reel inside, combining two separate operations (unboxing and mounting) into one simultaneous action.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The packaging box is pre-prepared with mechanically weakened portions and mounting features before the reel is placed in the apparatus. This preliminary preparation of the box allows for quick mounting without requiring additional steps to prepare the reel itself.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the reel is stored unboxed, then it is easily accessible, but sheet material strips may become entangled

Engineering Contradiction:

Improvestorage convenienceVSAvoidentanglement of sheet material

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The reel remains nested within the packaging box during storage and transport. The box provides a confined space that prevents the sheet material from becoming entangled while still allowing the reel to be easily accessed and moved as a complete unit.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The packaging box acts as a flexible protective shell that contains the reel. This shell maintains the structural integrity of the stored material while allowing for easy handling and transport of the complete assembly.

Inventive Principle:

Principle #30Flexible shells and thin films

4Strength

If the packaging box is made rigid for protection, then the reel is well-protected, but the mandrel cannot pass through for mounting

Engineering Contradiction:

Improveprotective strength of packagingVSAvoidmounting ease

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The packaging box has different mechanical properties in different locations. The faces opposite each other have mechanically weakened portions that are easily penetrable by the mandrel, while the rest of the box structure remains rigid to provide protection. This local variation in mechanical quality allows both protection and easy mounting.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The packaging box is segmented into regions of different mechanical strength. The mechanically weakened portions are localized areas designed for mandrel penetration, while the remaining structure maintains full protective strength. This segmentation allows the box to serve dual functions of protection and easy mounting.

Inventive Principle:

Principle #1Segmentation
