Bag Construction with Side Gussets for Upright Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag constructions for dispersible materials face difficulties in standing upright for storage and filling, leading to challenges in storage, stacking, and distribution, as well as issues with the rib-and-trough closure system causing leaks and contamination.
Innovation Solution
A bag construction with side gussets and an internal gusset featuring distribution apertures, a transverse seal, and an anti-tamper arrangement, allowing for upright standing, easy filling, and secure distribution of materials while preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bag construction uses a conventional bottom portion without side gussets, then the bag can be manufactured with simpler structure, but the bag cannot stand upright for storage and stacking
Solution Approach 1:
The bag construction is divided into multiple panel sections (front panel, back panel, side gussets) that are separately formed and then assembled together. The side gussets are separate panels that extend from the bottom corners upward, creating expandable sides while maintaining a simple overall structure that can stand upright.
Solution Approach 2:
The bag transitions from a two-dimensional flat configuration to a three-dimensional upright structure by adding vertical side gussets that extend upward from the bottom portion. This dimensional change enables the bag to stand upright while maintaining manufacturing simplicity through panel formation and assembly.
2Productivity
If the bag construction lacks expandability along the sides or bottom portion, then the manufacturing process is simpler, but the filling process becomes difficult and volume is reduced
Solution Approach 1:
The bag construction incorporates flexible side gussets that can expand dynamically during the filling process. These gussets allow the bag to accommodate increasing volumes of material without tearing, enabling efficient filling while maintaining structural integrity through the assembled panel configuration.
3Reliability
If the rib-and-trough closure system is used, then the bag can be sealed, but particulate materials get stuck inside the trough portion making operation difficult
Solution Approach 1:
The problematic trough portion is extracted from the closure system design. Instead of using a rib-and-trough mechanism where materials can become trapped, the invention employs a closure system without a trough component, eliminating the source of material entrapment while maintaining sealing capability.
Solution Approach 2:
The closure mechanism is inverted from the conventional rib-and-trough design to an alternative configuration that does not rely on a trough structure. This inversion eliminates the trap for particulate materials while preserving the essential sealing function through a different mechanical arrangement.
4Reliability
If the prior art bag construction is used, then manufacturing may be easier, but leaks and contamination occur during storage
Solution Approach 1:
The bag construction uses segmented panel sections that are assembled together with secure sealing. The division into front panel, back panel, and side gussets allows for robust construction and reliable sealing at the joints, preventing leaks and contamination while maintaining manufacturability through standardized assembly processes.
