Dispensing Carton Offset Divider Panel Axial Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Known dispensing cartons lack optimal strength under compressive loads due to bending or deflection of divider panels when compressed, which reduces axial stiffness and is critical for stacked cartons during shipping and storage.
Innovation Solution
A dispensing carton design with a divider panel whose lower edge is offset from the bottom panel, providing a relief area and increased axial stiffness, and optionally featuring an inclined lower edge to prevent bending and enhance compressive strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the divider panel extends to the bottom panel of the carton, then the divider panel provides structural support and separates articles, but the divider panel bends or deflects under compressive loads reducing axial stiffness
Solution Approach 1:
The lower edge of the divider panel is offset from the bottom panel, extracting the problematic contact point between the divider panel and bottom panel. This offset position removes the source of bending moments that cause deflection under compression, allowing the divider panel to maintain axial stiffness while still providing structural support and article separation functionality
2Volume of moving object
If the divider panel is positioned close to the bottom panel, then the carton structure is compact, but the divider panel deflects under axial loads reducing carton strength
Solution Approach 1:
The divider panel is positioned at an offset distance from the bottom panel, utilizing the vertical dimension to create separation between the divider panel lower edge and the bottom panel. This dimensional adjustment allows the divider panel to function effectively while maintaining carton compressive strength by preventing bending deflection under axial loads

AI summary
A carton comprises a divider panel that connects a front panel of the carton to a back panel. The lower edge of the divider panel is offset from the bottom panel, and therefore is less likely to buckle or bend when the carton is subjected to axial compression. The divider panel therefore provides greater axial stiffness and strength to the carton.
