Roll-Up Reusable Bag Holder With Pockets for Cart Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reusable bag holders for shopping carts are inefficient, ill-fitting, and cumbersome, leading to space wastage, bag collapse, and difficulty in accessing personal items during shopping, resulting in a suboptimal shopping experience.
Innovation Solution
A pocketed reusable bag holder with a fabric or synthetic material that rolls up for storage, featuring hook-and-loop fasteners for secure attachment to shopping cart handles, pockets for personal items, and a pivoting hook for bag organization, allowing easy access and organization of bags and personal items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If reusable bag holders are attached to shopping cart handles, then bags can be organized and stored, but the holders use excessive cart space and have ill-fitting rods that poke out or are too short
Solution Approach 1:
The bag holder is divided into multiple compartments and sections, including a main storage area, a mesh pocket for small items, and a secondary pocket for additional organization. This segmentation allows efficient use of space while maintaining accessibility to different bag types and personal items.
Solution Approach 2:
The holder features nested pockets and compartments where smaller storage areas are integrated within the main structure. The mesh pocket is nested within the holder body, and additional smaller pockets are integrated into the sides, maximizing space utilization without increasing overall volume.
2Quantity of substance
If large reusable bags are used to accommodate groceries, then capacity is increased, but the bags become too heavy to carry and drag on the floor
Solution Approach 1:
The holder separates grocery bags from personal items using distinct compartments. The main area holds reusable grocery bags while smaller mesh pockets contain lightweight personal items like lists, scanners, and sanitizer, distributing weight more effectively and preventing floor dragging.
3Volume of moving object
If bags are allowed to pool at the bottom of carts, then space is maximized, but fragile items smash together and break
Solution Approach 1:
The holder creates separated zones for different items. The main compartment holds bags while the mesh pocket and secondary pockets isolate fragile personal items, preventing them from moving freely and colliding with each other or groceries in the cart.
4Ease of operation
If bags are stored in conventional holders, then they can be carried, but the bottoms are flimsy and bags cannot stand upright without collapsing
Solution Approach 1:
The holder features a reinforced bottom structure with extended support panels that provide rigidity where needed. The bottom of the holder is constructed with additional material layers and structural reinforcement to maintain shape and support bags in an upright position without collapsing.
5Ease of operation
If shoppers must unload groceries completely before moving the cart to repack bags, then bags can be accessed, but time is wasted
Solution Approach 1:
The holder is pre-attached to the cart handle and maintains continuous accessibility throughout the shopping trip. Bags and personal items remain organized and reachable without requiring the cart to be stopped or groceries to be unloaded, enabling shoppers to access items during normal shopping activities.
6Ease of operation
If personal items are carried separately, then they can be accessed, but convenience is reduced and items may be lost
Solution Approach 1:
The holder combines multiple functions into a single integrated unit: grocery bag storage, personal item pockets, and cart attachment. The mesh pocket and secondary pocket are integrated into the holder structure, eliminating the need for separate carrying methods while maintaining organization and accessibility.

AI summary
A pocketed reusable bag holder, organizer, and storage apparatus and system of use thereof, configured to facilitate the easy transport, storage, and use of reusable bags conventionally employed for grocery shopping. The holder exhibits a body having a generally planar shape which is configured to roll up while containing multiple reusable bags when not in use. When needed, the body is unrolled, revealing the reusable bags which are stored in an organized fashion on a hook. The body is mountable to a handle of a shopping cart via multiple hook-and-loop fasteners. Pockets are present on a front and a rear of the unrolled body, which facilitate storage of personal items during the shopping experience, such as a mobile device, shopping list, and coupons. A stabilizing bar prevents undesired torsion of the body during use.
