Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing manual order preparation and packaging operations require double handling of items, and existing removable bottom boxes do not allow secure placement of articles at the bottom of a carton without falling.

Innovation Solution

A transfer box with a sliding bottom wall and drive means that transitions between deployed and withdrawn positions, allowing articles to be placed at the bottom of a carton in their initial storage or packaging position without falling, and optimizing space utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a removable bottom box is used, then articles can be transferred into a carton, but the articles cannot be securely placed at the bottom of the carton without falling

Engineering Contradiction:

Improvesecure placement of articlesVSAvoidarticle placement stability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The bottom wall is designed to be movable, transitioning between a deployed position (closing the bottom of the transfer box) and a withdrawn position (allowing articles to be deposited at the bottom of the carton). This dynamic structure enables the bottom wall to provide support during transfer and then recede to allow secure article placement without falling.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If manual order preparation operations are used, then items can be picked and collected, but double handling of items is required

Engineering Contradiction:

Improveitem handling processVSAvoidoperational efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The transfer box combines the functions of article storage, transfer, and deposition into a single integrated device. The box can be loaded with articles, transferred to the carton, and then used to deposit articles directly at the bottom of the carton in their initial storage position, eliminating the need for separate picking and packing operations.

Inventive Principle:

Principle #5Merging (Combining)

3Volume of stationary object

If articles are placed in their initial storage position, then space utilization is optimized, but articles may fall to the bottom of the carton

Engineering Contradiction:

Improvespace utilization in cartonVSAvoidarticle placement stability

Core Design Contradiction:

Volume of stationary objectVSReliability

Solution Approach 1:

The movable bottom wall transitions from a deployed position that supports articles during transfer to a withdrawn position that allows articles to be deposited securely at the bottom of the carton in their initial storage position, preventing falling while optimizing space utilization.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The bottom wall acts as an intermediary structure that temporarily supports articles during the transfer process and then recedes to allow direct placement of articles at the bottom of the carton, ensuring both secure placement and optimal space usage.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invention relates to a transfer box (1) for transferring articles into a carboard box comprising a bottom wall (2) that is able to slide between a deployed position, in which the bottom of the transfer box (1) is closed, and a retracted position, a means (10) for driving the bottom wall (2), two opposite side walls (3, 4), the bottom wall (2) being able to slide along one of the side walls (3, 4) when it is actuated, via the drive means (10), from the deployed position to the retracted position.
