Solution Overview

Problem

Existing containers made of cardboard or paper require multiple separate elements for manufacturing and often have difficulties in stacking and storing multiple units due to their shape, leading to increased costs and environmental impact.

Innovation Solution

A one-piece blank design for containers with integrated partitions and a saddle-shaped structure that allows for easy assembly, improved stackability, and secure closure, using materials like cardboard or corrugated board to reduce the need for additional parts and enhance storage efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate elements are used to create subdivisions within the storage space, then the container can be manufactured with compartments, but the manufacturing complexity and cost increase

Engineering Contradiction:
Improvestorage space subdivisionVSAvoidnumber of separate elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple container elements (bottom wall, side walls, lid wall, and partition walls) into a single blank that is manufactured as one piece. The partition walls are formed by fold lines within the same blank, eliminating the need for separate partition components and reducing assembly complexity while maintaining the ability to subdivide storage space.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single blank is segmented into multiple functional areas through fold lines and cut lines, allowing the container to be folded into compartments. The partition walls are created by folding specific sections of the blank along predetermined fold lines, enabling storage space subdivision without requiring separate parts.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If traditional container shapes are used, then manufacturing is simple, but stackability and storage efficiency are poor

Engineering Contradiction:
Improveblank constructionVSAvoidstackability
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The container is designed with a saddle shape featuring curved surfaces and rounded edges. The blank includes curved side walls that fold to form a three-dimensional saddle-shaped container, improving stackability and storage efficiency while maintaining ease of manufacture from a single molded blank.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Adaptability or versatility

If separate lid and base elements are manufactured, then assembly is flexible, but production cost and environmental impact increase

Engineering Contradiction:
Improvecontainer configurationVSAvoidmaterial waste and environmental impact
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent combines the lid wall, bottom wall, side walls, and partition walls into a single integrated blank. This one-piece construction eliminates the need for separate lid and base elements, reducing material waste and environmental impact while maintaining the ability to form different container configurations through folding.

Inventive Principle:
Principle #5Merging (Combining)
