Trashcan Bag Engaging Member for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trashcan devices fail to securely attach trash bags to the can, causing them to slip and fall back into the container.
Innovation Solution
A trashcan assembly with a peripheral wall featuring a rim and bag engaging members, such as slits or stick-on devices, that secure the trash bag to the outer surface, preventing it from falling back into the can by using resilient sections and adhesives to frictionally hold the bag in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional trashcan devices are used without specialized securing mechanisms, then the device complexity is low, but the reliability of trash bag attachment deteriorates causing bags to slip and fall into the container
Solution Approach 1:
The trashcan assembly is segmented by adding discrete bag engaging members (clips, clips arrays, or slit arrangements) that can be independently positioned on the peripheral wall. These segmented securing elements provide reliable bag attachment without requiring complete redesign of the entire trashcan structure, thus improving reliability while maintaining reasonable complexity
Solution Approach 2:
Bag engaging members serve as intermediary elements between the trashcan peripheral wall and the trash bag. These intermediaries (clips, slit arrangements, or adhesive structures) facilitate secure attachment by providing a mechanical interface that connects the bag to the can, resolving the contradiction between simple design and reliable attachment
2Reliability
If bag engaging members with resilient sections are used to frictionally secure the trash bag, then the reliability of bag retention improves, but the ease of manufacture deteriorates due to additional manufacturing steps
Solution Approach 1:
The resilient sections of the bag engaging members are designed with specific material parameters (elasticity, flexibility) that enable them to frictionally engage the trash bag. By optimizing these material parameters, reliable bag retention is achieved while the manufacturing process remains relatively simple, as it primarily involves forming or attaching pre-manufactured resilient components
Solution Approach 2:
The resilient sections function as flexible elements within the bag engaging members, allowing them to deform and grip the trash bag securely. This use of flexible components achieves reliable retention while maintaining ease of manufacture, as flexible materials can be easily formed or attached to the peripheral wall structure

Function Achieved in This Case
The solution effectively prevents trash bags from slipping and falling into the trashcan, ensuring they remain securely attached and are easily replaced or dispensed.
Implementation Method 1
a plurality of resiliently flexible sections being defined between adjacent ones of the slots, wherein a portion of the trash bag may be extended into a respective aperture and frictionally secured therein by the sections
Implementation Method 2
a plurality of resilient sections being defined between adjacent ones of the slots
Implementation Method 3
Another type of trashcan device is disclosed in U.S. Pat. No. 5,636,416, which is incorporated herein by reference, which device has a conventional shape and which includes clips that are attachable to a trash bag

AI summary
A trashcan assembly includes a container having a bottom wall and a peripheral wall extending upwardly from said bottom wall, a rim of said peripheral wall defining an opening extending into said container; and a bag engaging member located in an area of said peripheral wall The bag engaging member includes a housing separate from said peripheral wall, said housing having a surface that is generally parallel to a plane of said peripheral wall in said area and is configured for receiving a portion of a trash bag for securing the trash bag to an outer surface of said peripheral wall. A trash bag may be extended over said rim and secured to said peripheral wall with said bag engaging member.
