Carton Bottom Door Pivoting for Access and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Enclosed cartons with dispensing features often make it difficult to remove articles, especially those in lower columns, due to the design of the dispenser opening, which can be too low, causing accessibility issues and potential escape of articles.
Innovation Solution
A carton design featuring a pivoting bottom door that can be opened to create a higher access aperture, allowing for easy removal of articles without weakening the carton structure and providing a self-closing mechanism to prevent inadvertent escape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional dispenser opening is used in the side panels, then the dispenser can be opened to access articles, but the opening is too low causing difficulty in removing articles from lower columns
Solution Approach 1:
The bottom door is segmented from the side panels and end panels, allowing it to pivot independently to provide a higher access aperture. This segmentation enables the bottom door to be opened separately to access articles in lower columns without requiring the entire dispenser structure to be complex.
Solution Approach 2:
Instead of only providing access through the side panels, the invention adds a third dimension by incorporating a pivoting bottom door that opens downward. This creates a higher access aperture that allows users to reach articles in lower columns more easily, adding vertical accessibility to the horizontal dispenser opening.
2Ease of operation
If the bottom door is made to provide access without weakening panels, then article removal is facilitated, but the carton structure must maintain strength and rigidity
Solution Approach 1:
The bottom door is constructed with specific local qualities - it includes reinforcement elements and is positioned to distribute stresses appropriately. The door panel itself is designed with appropriate thickness and structural features that allow it to pivot for article removal while maintaining the overall strength and rigidity of the carton structure.
Solution Approach 2:
The bottom door is pre-formed with reinforcement features and proper structural design during carton manufacturing. This preliminary action ensures that when the door is later opened for article removal, the carton structure maintains its strength and rigidity without requiring additional strengthening measures.
3Ease of operation
If the dispenser opening is made higher, then article accessibility improves, but the side walls may become weaker reducing carton strength
Solution Approach 1:
The bottom door is segmented as a separate movable component from the side panels and end panels. This segmentation allows the access aperture to be positioned higher while the side walls remain intact and structurally sound, maintaining carton strength while improving accessibility.
Solution Approach 2:
The bottom door is designed as a dynamic, pivoting component rather than a fixed opening. This allows the access aperture to be positioned higher in the carton structure while the door can pivot downward to provide access, maintaining side wall strength when closed and providing high access when open.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the accessibility and usability of the carton by allowing easy removal of articles without compromising the carton's strength and rigidity, while preventing accidental loss of contents.
Implementation Method 1
a carton includes a bottom door that can be pivoted open to create an opening in the lower part of the dispensing or exiting end of the carton
