Rotatable Bag Rack for Plastic and Reusable Bag Types
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bag racks are designed for specific types of bags, such as plastic 'T-shirt' or reusable bags, making it difficult and costly for retailers to accommodate both types simultaneously, as they need to replace racks or predict the mix of bag types required, which can be inefficient and unsatisfactory for customers.
Innovation Solution
A convertible bag rack that can be rotated between two support positions, one for plastic 'T-shirt' bags and another for reusable bags, using a pivotally mounted rack with a locking pin mechanism to adapt to different bag designs, allowing easy switching between bag types without the need for multiple racks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If retailers use separate racks for plastic T-shirt bags and reusable bags, then each bag type can be properly supported, but the device complexity and cost increase due to needing multiple racks
Solution Approach 1:
The bag rack is designed with a rotatable support structure that can be positioned in multiple configurations to accommodate different bag types. The support can rotate between a first position for plastic T-shirt bags and a second position for reusable bags, allowing a single rack to perform multiple functions that previously required separate racks.
Solution Approach 2:
The rack incorporates a rotatable support mechanism that can dynamically change its position between different orientations. This dynamic adjustment allows the same physical structure to adapt to different bag types by rotating the support to the appropriate position, eliminating the need for static, dedicated racks for each bag type.
2Adaptability or versatility
If retailers replace racks to accommodate different bag types, then proper support is provided, but the loss of time and productivity increase due to replacement operations
Solution Approach 1:
The rotatable support mechanism allows rapid switching between bag types by simply rotating the support to the appropriate position, eliminating the time-consuming process of physically replacing entire racks. The dynamic repositioning takes moments compared to full rack replacement operations.
3Adaptability or versatility
If retailers install multiple rack types, then all bag types can be supported, but the manufacturing cost and device complexity increase
Solution Approach 1:
By designing a single rack with a rotatable support that can accommodate multiple bag types through position changes, retailers avoid the expense of manufacturing and installing multiple specialized racks. The universal design consolidates what would otherwise require several different rack installations into one versatile unit.

AI summary
A rotatable bag rack to support a plurality of bag types. The bag rack includes a stand and a rack. The rack is pivotally mounted to the stand so as to be rotatable about a pivot axis relative to the stand between a first position to hold a first bag type and a second position to hold a second bag type. The rack includes a pair of spaced apart arms to hold the first bag type that, in the first position, extends forward relative to the pivot axis. The rack, in the second position, extends downward relative to the pivot axis. The rack also includes a hanger fixed relative to the arms to hold a second bag type that, in the first position, extends backward relative to the pivot axis. The rack, in the second position, extends upward relative to the pivot axis.
