Pivoting Roll Support for Flat-Packed Adhesive Roll Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for replacement adhesive rolls require manual assembly, increasing labor and overall costs due to the need for bending and folding of cardboard components.
Innovation Solution
A display holder with a flexible planar main body and pivotally attached roll support, allowing for easy insertion and locking of the adhesive roll without manual assembly, utilizing fold lines and tabs for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual assembly of the display device is used, then the device can be constructed from a one-piece cardboard blank, but labor cost and overall cost increase
Solution Approach 1:
The display device is divided into separate components: a main body and a roll support assembly. The roll support assembly includes support tabs and locking tabs that can be independently manufactured and then assembled to the main body, eliminating the need for manual bending and folding of a one-piece blank.
Solution Approach 2:
The locking tabs and support tabs are pre-formed on the roll support assembly before final assembly. This preliminary formation of tabs and creases allows the components to be prepared in advance through automated processes, eliminating manual assembly steps during final construction.
2Device complexity
If manual bending and folding of cardboard components is required, then the display device can be assembled from a one-piece blank, but labor cost increases
Solution Approach 1:
The integrated structure is divided into modular components with pre-formed features. The roll support assembly is separated from the main body, with locking tabs and support tabs pre-formed on the roll support. This segmentation allows automated manufacturing of individual components without requiring manual bending and folding operations.
3Reliability
If the roll support extends laterally outwardly, then the adhesive roll can be securely supported, but the device occupies more space during shipping
Solution Approach 1:
The roll support assembly is designed to be movable relative to the main body through a hinge connection. The roll support can pivot between a retracted position for compact shipping and an extended operative position for displaying and supporting the adhesive roll. This dynamic configuration allows the same structure to serve both compact storage and functional support requirements.
Solution Approach 2:
The roll support assembly can be collapsed and nested against the main body when not in use, creating a compact configuration for shipping. When needed, the roll support extends outward to provide the necessary support function, effectively nesting the support structure within the main body volume during transport.

AI summary
A display holder for a tubular cylindrical roll, such as a lint roller. The holder includes a planar main section constructed of a flexible material as well as a roll support which is pivotally mounted to the lower end of the main body between an operable position and a collapsed position. In its operable position, the roll support extends outwardly from the main body and supports the lower end of a roll inserted over the main body. Conversely, in its collapsed position, the roll support folds flatly against the main body for shipping and high density packing.
