Display Box Retention Flap Design for Cylindrical Container Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display boxes fail to securely retain cylindrical containers without rotation, limiting the visibility of labels and being inflexible for different container sizes and shapes.
Innovation Solution
A display box design featuring elongate flaps with crease lines that fold into a base, providing multiple contact points to securely hold containers in place, with a flap structure that includes a longer lateral portion to prevent rotation and a second flap for additional support, allowing for secure positioning and flexibility across various container sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional flaps are used to hold the container, then the container is kept raised and protected from impact, but the container can still rotate and move within the box
Solution Approach 1:
The retention flap is divided into multiple functional segments: a first lateral portion for initial contact and positioning, a vertical portion for additional support, and a second lateral portion for final securing. This segmentation allows each portion to perform a specific retention function, preventing both rotation and displacement of the container while maintaining protection.
2Stability of the object's composition
If additional sections with cut-outs are added to prevent rotation, then the container rotation is prevented, but the box structure becomes more complex and less flexible for different container sizes
Solution Approach 1:
The retention flap is designed as a dynamic structure that adapts to different container sizes and positions. The multi-portion configuration allows the flap to flex and adjust its contact points with the container, providing rotation prevention without requiring fixed cut-outs or rigid structures. This dynamic adaptation maintains structural simplicity while ensuring container stability.
3Ease of manufacture
If a fixed flap structure is used, then the manufacturing process is simple, but the box cannot accommodate different container sizes and shapes
Solution Approach 1:
The retention flap with its multi-portion structure serves multiple functions simultaneously: it raises the container for protection, prevents rotation through lateral contact, and accommodates different container sizes through its flexible configuration. This universal design allows a single flap structure to handle various container dimensions and shapes without requiring multiple specialized components, maintaining manufacturing simplicity while enhancing adaptability.

AI summary
A display box is provided for housing and retaining a cylindrical container. The box may include two side walls and a front and rear wall, a top lid extending from an upper end of one of the walls and a bottom lid extending from the lower end of the same or a different wall. At least one elongate flap further extends from the lower end of one of said side walls or rear wall, said flap being provided with crease lines along which said flap may be folded. The flap has an end portion adhered to the inner surface of the wall from which the flap extends, a first lateral portion having a proximal end adjacent the wall and a distal end extending into the box. A vertical portion extends down from the distal end of the first lateral portion and a second lateral portion connects a lower end of the vertical portion and a distal end of a base portion. The length l1 of the first lateral portion is greater than the distance D1 between the inner surface of the wall from which the flap extends and the wall of a container being held in the box.
