Solution Overview

Problem

Existing packaging solutions struggle to securely fix the packaging cover to the packaging bottom, which can lead to instability and potential damage during transport of packaged articles.

Innovation Solution

A packaging system featuring a three-dimensionally shaped packaging bottom made of leaf material with a protruding bottom edge and a packaging cover with recesses, where the bottom edge portions engage in the recesses to securely fix the cover in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the packaging cover is simply placed on the packaging bottom, then the packaging structure is simple, but the fixability and stability during transport is insufficient

Engineering Contradiction:

Improvefixability of packaging coverVSAvoidpackaging structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The packaging bottom edge is segmented into multiple bottom edge portions that can independently engage with corresponding recesses in the packaging cover, creating multiple fixed points that enhance overall stability without requiring a complex fastening mechanism

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bottom edge portions are integrated within the packaging bottom structure, and the recesses are integrated within the packaging cover structure, creating a nested engagement system where the edge portions fit into the recesses to form a unified stable assembly

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If traditional smooth-edged packaging bottoms are used, then the manufacturing is easier, but the adhesion to the packaging cover recesses is insufficient

Engineering Contradiction:

Improveadhesion to recessesVSAvoidbottom edge formation

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The packaging bottom edge is designed with locally differentiated properties: the bottom edge portions have increased protrusion and rough surface characteristics specifically at the engagement zones to enhance adhesion, while the rest of the packaging bottom maintains its original smooth structure for ease of manufacture

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The bottom edge portions are formed with a rough surface structure that increases surface area and creates mechanical interlocking with the recesses, enhancing adhesion through physical interlocking rather than chemical bonding

Inventive Principle:

Principle #31Porous materials

AI summary

The disclosure relates to a packaging for an article, comprising: a three-dimensionally shaped packaging bottom of a leaf material of a plant, the packaging bottom being adapted to receive an article to be packaged and comprising: a bottom support surface, a bottom side wall surrounding the bottom support surface, and a bottom edge arranged at an end of the bottom side wall, the end being distal with respect to the bottom support surface, wherein the bottom edge protrudes outwardly from the bottom side wall; and a packing cover comprising recesses. The packing cover is arranged on the packaging bottom such that outwardly projecting bottom edge portions engage in respective ones of the recesses of the packing cover such that the packing cover is fixed in its relative position with respect to the packaging bottom. Furthermore, a packaged article is provided.
