Three-Way Containment Device With Mat-to-Bag Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for small items, such as rigid and flexible bags, are inconvenient for transport, prone to spilling, and inefficient for cleaning up scattered items, lacking the ability to maintain visibility and accessibility of contents.
Innovation Solution
A convertible containment device that can transform between a mat, a drawstring bag, and a cylindrical bag configuration, utilizing a flexible elliptical base, a flexible lip, and a cord system to securely contain items in various forms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid containers are used to store small items, then items are securely contained, but the container is difficult to carry and stow, and items stack up making them invisible and inaccessible
Solution Approach 1:
The patent employs flexible fabric material instead of rigid structures, allowing the container to be collapsed and rolled for easy carrying while maintaining containment capability. The flexible material conforms to the user's body when carried and can be stowed in compact spaces, directly resolving the portability issue while preserving item security through the enclosed design.
Solution Approach 2:
The patent introduces a third dimension by creating a container with depth and volume rather than a flat surface. The enclosed three-dimensional space allows items to be stored without stacking flat against each other, improving accessibility while maintaining secure containment through the closed fabric structure.
2Reliability
If rigid containers are used to transport items, then items are contained securely, but the container is breakable and may release items when dropped
Solution Approach 1:
The patent uses flexible fabric material that can absorb impact forces through deformation rather than breaking. When dropped, the flexible material bends and deforms to dissipate energy, preventing the container from cracking open and releasing items, thus providing impact resistance while maintaining containment security.
3Ease of operation
If flexible bags are used to contain small items, then portability is improved, but small items can fall out when dropped or shaken
Solution Approach 1:
The patent employs flexible fabric material that maintains containment security through its enclosed design and secure closure mechanisms. The flexible structure prevents item escape during normal handling while remaining portable and comfortable to carry, resolving the contradiction between portability and containment reliability.
4Productivity
If conventional containers are used for cleaning up scattered items, then items can be collected, but the process is slow and tedious requiring individual pickup
Solution Approach 1:
The patent uses a flexible fabric container that can be easily spread out on the ground to create a large collection area. Items can be gathered and contained within the flexible boundaries, allowing for more efficient collection compared to rigid containers that require precise placement. The flexible material adapts to the ground surface, enabling faster cleanup of scattered items.

AI summary
A containment device that converts between three different configurations or forms and includes a multilayer base. The forms include: 1) a mat or work surface that has a raised lip or edge structure that contains items on the mat or work surface; 2) a small volume bag or flexible container for holding the items inside, where the lip is gathered or compacted, e.g., by a drawstring, to form an annulus from the lip; and 3) a larger-volume, cylindrical-shaped bag, which may be used as a shopping bag. The cylindrical-shaped bag may be stored between the layers of the base when the device is in the mat configuration or the drawstring bag configuration, and the lip may be stored between the layers of the base when the device is in the cylindrical-shaped bag configuration.
