Three-Sided Bag Rack for Fuller Filling of Gusseted T-Shirt Bags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plastic grocery bags are underutilized and wasteful due to their weak structure and lack of optimal packing efficiency, leading to increased environmental impact and operational inefficiencies in retail settings, where they do not maintain an erect shape on standard wire-arm bag racks, resulting in premature bag switching and reduced item capacity.
Innovation Solution
A three-sided bag rack and packing system that creates a defined physical frame for plastic, reusable, and paper bags, allowing for freestanding and efficient filling without human assistance, using handles to secure bags over hooks and loops, and a crossbar for item separation, enabling simultaneous dual bagging and uniform packing across various bag types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic grocery bags are used on standard wire-arm bag racks, then bags can be dispensed efficiently, but bags cannot maintain an erect shape and do not stand freely
Solution Approach 1:
A three-sided support structure acts as an intermediary between the wire-arm bag rack and the plastic grocery bag. The support provides a stable base and vertical walls that enable the bag to maintain an erect shape and stand freely, while still allowing efficient dispensing from the rack.
Solution Approach 2:
The invention changes the physical parameters of the bag support environment by introducing a three-sided structure with specific height and width dimensions. This creates a confined space that maintains the bag's erect shape through structural constraints rather than relying on the bag's own structural integrity.
2Reliability
If plastic grocery bags are underfilled to compensate for weak structure, then bag failures are reduced, but packing efficiency and volume utilization decrease
Solution Approach 1:
The three-sided support structure serves as a mediator that distributes and supports the weight of bag contents, reducing the structural burden on the plastic bag itself. This allows bags to be filled to their full capacity without compromising structural reliability.
Solution Approach 2:
The support structure is prepared in advance to provide the necessary structural framework before the bag is filled. This preliminary structural support enables maximum filling capacity while maintaining bag integrity throughout the packing process.
3Speed
If multiple plastic bags are grabbed at once, then bag dispensing speed increases, but bag waste increases due to sticking together
Solution Approach 1:
The three-sided support structure acts as a physical separator between individual bags, preventing them from sticking together even when multiple bags are handled simultaneously. This intermediary structure allows faster bag dispensing without increasing bag waste.
4Ease of manufacture
If plastic grocery bags are used instead of paper bags, then cost is reduced, but environmental impact and waste increase
Solution Approach 1:
The invention changes the usage parameters of plastic grocery bags by enabling them to be filled to their full capacity. This increases the number of items per bag, reduces the total number of bags needed, and consequently decreases environmental impact while maintaining the cost advantage of plastic bags.

AI summary
A bagging system that permits one or two plastic bags to be filled at the same time, one of which can be filled more fully as it is supported by a three-sided support off from a three-sided bag rack. A cross bar can be used to help create two separate areas in which two plastic bags are filled. The same bagging system can also be used with non-plastic and non-standard bags by placing such bags inside of the system, between the three-sided support and the three-sided bag rack, and securing handles of the bag to the bagging system.
