Paperboard Storage Sleeve With Segmented Pull-Out Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing merchandise storage containers made from recyclable paperboard lack configurations that allow simultaneous extension and retraction of pull-out holders without jamming, and there is a need for containers entirely fabricated from recyclable materials.
Innovation Solution
A merchandise storage container with a sleeve and pair of pull-out holders that can be extended and retracted simultaneously, featuring anchors to prevent removal and interference, and constructed from recyclable paper-based materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple pull-out holders are placed in a sleeve, then storage capacity is improved, but the holders may jam during operation
Solution Approach 1:
The interior of the sleeve is divided into separate compartments by partition walls, with each compartment housing one pull-out holder. This segmentation prevents the holders from interfering with each other during extension and retraction, eliminating jamming while maintaining storage capacity.
Solution Approach 2:
Partition walls act as intermediary structures between adjacent holders, physically separating their movement paths. This intermediary structure ensures that when one holder is pulled out, it does not obstruct the movement of neighboring holders, thus preventing jamming.
2Ease of operation
If holders can be pulled out from opposite sides simultaneously, then ease of operation is improved, but interference between holders may occur
Solution Approach 1:
The sleeve interior is segmented into independent compartments by partition walls, allowing holders on opposite sides to be pulled out simultaneously without interfering with each other. Each compartment operates independently, simplifying the interaction between holders.
3Adaptability or versatility
If the container is made entirely from recyclable paperboard, then environmental sustainability is improved, but structural strength may be reduced
Solution Approach 1:
The container uses paperboard as the base material and incorporates a clear plastic window formed from a flexible blank. This composite structure combines the recyclability and printability of paperboard with the durability and transparency of plastic, achieving both environmental sustainability and structural strength.
Solution Approach 2:
The flexible plastic blank serves multiple functions: it forms the clear window for product display, provides structural reinforcement to the paperboard sleeve, and can be molded into various shapes. This multi-functionality allows the container to maintain strength while using recyclable materials.

AI summary
A merchandise storage container having a sleeve and a pair of pull out merchandise holders that are both stored in the same sleeve but may be pulled out to extended positions from opposite sides of the sleeve. The sleeve is configured to allow the two holders to be pulled out to their extended positions simultaneously. The sleeve is also configured to allow the holders to be pushed back to their retracted positioned simultaneously without interfering with one another. The sleeve is configured to prevent the holders from jamming during the operation of the container.
