Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional packaging members are costly and require additional components for effectively retaining and protecting articles, leading to inefficiencies in packaging and unpacking processes.

Innovation Solution

A packaging member design that integrates an upper buffer member with a protrusion on the inner flap of the packaging box, which retains the second article without the need for separate retaining members, reducing costs and enhancing protection and unpacking efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate retaining members are used to hold articles in the packaging box, then the articles are securely retained and protected, but the packaging cost increases and the configuration becomes more complex

Engineering Contradiction:

Improvearticle retention and protectionVSAvoidpackaging configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the retaining function with the inner flap structure by adding a protrusion to the inner flap. This integration eliminates the need for separate retaining members, reducing component count and packaging complexity while maintaining effective article retention through the protrusion's contact with the article

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If additional components are added to retain and protect articles, then protection effectiveness improves, but manufacturing cost increases

Engineering Contradiction:

Improvearticle protectionVSAvoidpackaging manufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The retaining function is merged into the inner flap structure through the protrusion, eliminating the need for separate retaining members and reducing component count

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The inner flap is given multiple functions: it provides structural support for the packaging box, acts as a closing element for the opening, and through the protrusion, provides article retention and protection. This multi-functionality reduces the need for additional components

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If multiple separate components are used for packaging, then article protection is enhanced, but unpacking efficiency decreases

Engineering Contradiction:

Improvearticle protectionVSAvoidunpacking efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The retaining function is integrated into the inner flap structure, reducing the number of separate components that need to be manipulated during unpacking

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The protrusion is extracted as a specific feature of the inner flap that provides retaining functionality without requiring separate retaining members, simplifying the unpacking process

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A packaging member (1) includes a packaging box (20) and an upper buffer member (32). The upper buffer member (32) is arranged above a first article (Pr1) to be packaged and adjacently to an opening (20a) of the packaging box (20) and internally includes a housing region (S) for housing a second article (Pr2) to be packaged. The packaging box (20) includes an outer flap (22), an inner flap (23), and a protrusion (231). The protrusion (231) is provided on the inner flap (23) and protrudes, when the opening (20a) is closed by the outer flap (22), toward the housing region (S) in the upper buffer member (32) so as to contact the second article (Pr2) to be packaged.
