Bag Rack Assembly for Single-Person Food Packaging Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In grocery or food deli settings, packaging large preprocessed or precooked food items like rotisserie chickens is inefficient as it often requires two people to hold open a storage bag and place the item inside, necessitating a more efficient approach for single-person operation.
Innovation Solution
A bag rack system comprising a base assembly with side bars and crossbars, a hanger assembly for supporting storage bags, and a hooking assembly to hold open the bags, allowing single-person packaging by enabling easy access and resealing of storage bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If one person attempts to package large food items manually, then labor cost is reduced, but packaging efficiency deteriorates because it requires two people to hold open the bag and load the item
Solution Approach 1:
The rack holds multiple storage bags in a ready-to-use configuration before packaging begins. Bags are pre-positioned on the rack with openings facing forward, eliminating the need to search for or prepare bags during the packaging process. This preliminary arrangement enables continuous efficient packaging operations.
Solution Approach 2:
The rack serves as an intermediary device between the packaged food items and the storage bags. It provides the mechanical support and positioning function that would otherwise require a second person to perform manually, enabling single-person operation while maintaining packaging efficiency.
2Productivity
If multiple storage bags are kept ready for packaging, then packaging continuity is improved, but device complexity increases due to the need for a rack structure
Solution Approach 1:
The rack structure is divided into simple modular components: a base support structure and multiple horizontal bars for holding bags. Each bar independently holds one or more bags, allowing the system to scale by simply adding more bars rather than redesigning the entire structure. This segmentation keeps the device complexity low while enabling continuous packaging.
Solution Approach 2:
The rack structure serves multiple functions simultaneously: it supports the weight of multiple storage bags, positions them at the correct height and orientation for packaging, and provides structural stability. This multi-functionality reduces the need for additional separate devices, maintaining simplicity while enabling continuous operations.

AI summary
A bag rack and method of using the same is disclosed. The presently disclosed bag rack may include a bag rack that is formed of a base assembly and a hanger assembly on which multiple storage bags may be hung. A method of using the presently disclosed bag rack may include, but is not limited to, the steps of hanging the storage bags on the bag rack, opening the frontmost storage bag, holding open or propping open the storage bag using a bag hooking mechanism, placing the food item(s) or any other types of item(s) into the storage bag, removing the bag hooking mechanism, if used, closing the storage bag, and removing the filled storage bag from the bag rack.
