Foldable Container Holder for Paper Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container holders for paper bags fail to maintain containers in an upright position during transportation, leading to potential spillage and contamination of other items, especially when dealing with liquid containers.
Innovation Solution
A foldable container holder made of sheet material with a fastening part and two holding parts, featuring apertures and flexible flaps that secure containers in place by adhering to the inner bag wall, preventing tilting and spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple container holder structure is used, then manufacturing cost is reduced, but the container cannot be securely held in an upright position
Solution Approach 1:
The patent transitions from a two-dimensional flat sheet to a three-dimensional structure by folding the sheet along predetermined lines. This creates a container holder with depth and volume, enabling it to securely hold containers in an upright position while still being manufactured from a simple flat sheet, thus resolving the contradiction between manufacturing simplicity and structural effectiveness
Solution Approach 2:
The container holder is made from a flexible sheet material that can be folded and shaped into a three-dimensional structure. This flexible thin film approach allows the holder to be easily manufactured from flat sheets while forming a structure capable of securing containers upright, addressing both the ease of manufacture and container stability requirements
2Device complexity
If a flat sheet material is used for the container holder, then manufacturing simplicity is maintained, but the holder cannot prevent container tilting during transportation
Solution Approach 1:
The flat sheet material is divided into multiple sections by fold lines, creating distinct walls and compartments when folded. This segmentation transforms the simple flat sheet into a structured holder with multiple surfaces that can interact with the container, providing stability and preventing tilting during transportation
Solution Approach 2:
The patent transforms the two-dimensional flat sheet into a three-dimensional structure through folding, creating depth and multiple surfaces. This dimensional transformation enables the holder to securely cradle containers and prevent tilting, while the base structure remains a simple flat sheet for easy manufacturing
3Quantity of substance
If the container holder is made from a single flat sheet, then material usage is minimized, but the holder cannot provide sufficient support to keep containers upright
Solution Approach 1:
The patent creates a three-dimensional structure from a two-dimensional sheet by folding, maximizing the support capability within the constraints of the original flat material. This dimensional transformation allows the single sheet to provide sufficient structural support for keeping containers upright without requiring additional materials
Solution Approach 2:
The flexible sheet material is folded into a three-dimensional form that provides structural support. This approach maximizes the utility of the minimal material used, creating a holder with sufficient strength and support capability while maintaining material efficiency
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 container holder effectively maintains containers in a stable position, reducing spillage and protecting other items in the bag, while being environmentally friendly and cost-effective, with adaptable design for various container sizes and shapes.
Implementation Method 1
The fastening part has an adhesive strip installed for attaching the container holder to the inner wall of the bag
Implementation Method 2
the inner edge of said aperture comprises deformable flaps for fixing the container. As flaps in the apertures grasp the side wall of the container on different heights, tilting of said container in relation to said container holder is prevented
Implementation Method 3
The joints between said fastening part and the holding parts comprise a longitudinal fold line (crease line) located either side of the edges of said fastening part. When folded towards each other along said fold lines, said holding parts and fastening part form a three-dimensional structure
