Transport Bag Narrowed Middle Portion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible transport bags, or 'big bags,' face stability issues when stacked due to their constricted lower and expanded upper sections, leading to balance problems, especially in confined spaces like shipping containers, and are not effectively stable against hydrodynamic pressures.
Innovation Solution
A transport bag design featuring a narrowed middle portion with wider top and bottom sections, supported by internal plastic-based support elements and reinforced seams, which helps maintain shape and stability under pressure, and includes stretching strips and a lifting flap for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the container jacket is constricted in the bottom region and expands above, then the peripheral expansion and bulge of the container is minimized, but the stability and balance of the container is compromised
Solution Approach 1:
The container jacket is divided into multiple wall panels (front, rear, left, right) that can be independently configured with different geometric shapes. This segmentation allows each panel to contribute to both the desired shape (minimizing bulge) and the overall stability when assembled into a complete container.
Solution Approach 2:
Different wall panels are designed with different local geometric characteristics. The front and rear wall panels have different shapes from the left and right wall panels, creating local variations in structure that collectively provide both shape control and stability. Each panel's specific geometry is optimized for its position to achieve overall container stability.
2Volume of moving object
If the container expands in the upper part, then the storing volume is increased, but the stacking of containers is hampered and stability problems occur
Solution Approach 1:
The container is segmented into four distinct wall panels that can be configured to create an optimized volume distribution. This segmentation allows the container to achieve adequate storing volume while maintaining a profile suitable for stacking, as each panel contributes to the overall geometry.
Solution Approach 2:
The front and rear wall panels are designed with asymmetric shapes relative to the left and right wall panels. This asymmetric design allows the container to maximize volume in certain directions while maintaining a compact profile in stacking directions, resolving the contradiction between volume and stackability.

AI summary
The invention relates to a transport bag comprising a base, a top portion, and side walls extending between said base and top portion in such a way that a volume for storing granule, fluid, viscous, or semi-fluid materials is formed, wherein the transport bag comprises at least one narrowed portion extending through a middle axis of said side wall from a upper edge to a bottom edge of the side wall.
