Transport Bag with Gravity-Pivoting Opening Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport bags are either rigid and permanently open or automatically close with gravity, leading to inefficient space usage when not in use, as they either cannot be compressed or require significant effort to keep open during loading and unloading.
Innovation Solution
A transport bag design featuring a front and back wall connected via a bottom section that automatically opens and remains open for filling, with a pivotable opening bracket that shifts due to gravity, allowing the bag to fold compactly when not in use, and includes features like retaining straps, protective cover layers, and information carriers for identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transport bag is designed to be rigid and permanently open, then loading and unloading is facilitated, but space efficiency when not in use deteriorates
Solution Approach 1:
The transport bag transitions from a static rigid structure to a dynamic flexible structure that can automatically change its configuration. The flexible front and back walls enable the bag to switch between an open loaded state and a closed folded state, improving space efficiency while maintaining ease of operation during loading and unloading.
Solution Approach 2:
The physical state of the transport bag is changed from rigid to flexible, allowing it to adapt its shape and volume. This parameter change enables the bag to be compressed into a compact form when empty while maintaining structural integrity during operation, resolving the contradiction between operational ease and space efficiency.
2Device complexity
If the transport bag automatically closes with gravity, then structural simplicity is maintained, but operational efficiency deteriorates due to manual intervention required
Solution Approach 1:
The transport bag performs the opening action automatically through its own weight and gravitational force, eliminating the need for manual intervention. The flexible walls and bottom section self-open when the bag is placed on a surface, improving operational efficiency while maintaining structural simplicity through the use of gravity as the driving force.
3Ease of operation
If the transport bag remains open during transport, then loading accessibility is improved, but space utilization in storage deteriorates
Solution Approach 1:
The transport bag employs dynamic flexible walls that can adapt between open and closed configurations. During loading operations, the bag remains open for accessibility, but during storage, the flexible walls allow the bag to fold into a compact form, optimizing storage space utilization without compromising loading accessibility.
4Ease of operation
If manual effort is applied to keep the bag open, then loading and unloading is enabled, but operational complexity increases
Solution Approach 1:
The transport bag utilizes its own weight and gravitational force to automatically open itself during loading and unloading operations, eliminating the need for manual effort to keep the bag open. This self-service mechanism reduces operational complexity while enabling efficient loading and unloading without requiring additional actuators or complex opening mechanisms.

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 transport bag efficiently transitions between open and folded states, saving space when not in use, while ensuring easy loading and unloading, and providing protection and identification for transported items.
Implementation Method 1
an opening bracket (16) that connects the back wall (21a) and the front wall (21b) to one another and is mounted so as to be pivotable on the back wall (21a) and on the front wall (21b) respectively in such a manner as to be pivoted, originating from the second configuration, from an inclined second position into a less inclined first position due to the intrinsic weight thereof

AI summary
A transport bag (15) for transporting and/or storing articles comprises a front wall (21b) and a back wall (21a) that are flexibly connected to one another via a bottom section (21c) so as to be movable back and forth between a first configuration in which the front wall and back wall form an upwardly open bag that can be filled from above, and a second configuration in which the front wall and back wall lie closely alongside one another and form a bag that is folded together, wherein the back wall (21a) is extended upward above and beyond the height of the front wall (21b) with a support section (15a) for fastening the transport bag (15) to a transport device (10.2). Easy filling and emptying of the transport bag (15) is achieved by providing an opening (16, 19, 20) that automatically brings the transport bag (15) into the first configuration and keeps the transport bag there, and allows a deliberate shift from the first configuration into the second configuration.
