Trash Liner Retention Disk With Flexible Flaps for Slip Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash liner securing devices, such as those with rigid members like prongs, slots, teeth, or flaps, are difficult to manipulate, pose a risk of injury, require manual dexterity, and lack versatility in accommodating different trash liners, leading to unsanitary and time-consuming situations.
Innovation Solution
A disk-shaped device made of chipboard or molded rubber with triangular or arced curvilinear flaps, serving as a hinge mechanism, secures trash liners by threading through a central point and adapting to the liner's shape, with an optional adhesive strip for closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid members like prongs, slots, teeth, or flaps are used to secure trash liners, then the device can hold the liner in place, but the device becomes difficult to manipulate and poses a risk of injury
Solution Approach 1:
The patent replaces rigid members with a flexible membrane structure that has openings forming flaps. The membrane is made of flexible material that can deform to receive and retain the trash liner without the rigidity that causes manipulation difficulties and injury risks. The flexible nature allows easy insertion and adjustment while maintaining secure retention.
Solution Approach 2:
The patent changes the physical state of the securing mechanism from rigid to flexible. By using a flexible membrane instead of rigid prongs or teeth, the device transforms its mechanical properties to achieve both secure retention and ease of operation. The flexible membrane can adapt its shape and stiffness dynamically during use.
2Reliability
If rigid members like prongs, slots, teeth, or flaps are used to secure trash liners, then the device can hold the liner in place, but the device lacks versatility in accommodating different trash liners
Solution Approach 1:
The flexible membrane structure can deform and adapt its shape to accommodate different sizes, shapes, and thicknesses of trash liners. Unlike rigid members that are fixed in form, the flexible membrane can conform to various liner configurations, providing universal compatibility while maintaining secure retention through its ability to grip and hold the liner material.
3Reliability
If rigid members like prongs, slots, teeth, or flaps are used to secure trash liners, then the device can hold the liner in place, but the device requires manual dexterity and is time-consuming to install
Solution Approach 1:
The flexible membrane with openings allows the trash liner to be easily threaded through and secured without requiring precise manual manipulation of rigid components. The flexibility enables the membrane to naturally conform to the liner and secure it in place with minimal user effort and time, eliminating the need for careful positioning and adjustment that rigid members require.

AI summary
The present invention relates to a disk-shaped device for securing plastic trash liners in a trash receptacle, with two durable 53 mm diameter, 3 mm thick embodiments. The first embodiment has eight isosceles triangular flaps, positioned around the central point, with tips at the center and bases in contact with the circumferential rim. The liner is threaded through the central point or aperture, allowing the flaps to flex and create a tight seal, preventing slipping.The second embodiment is crafted from molded rubber with a hardness rating of 90 Shore A and includes eight curvilinear arced triangular flaps. These flaps are positioned around the central point, with bases in contact with the circumferential rim and tips encircling a central 2 mm aperture. Each flap extends inwardly at an acute angle of 12 degrees relative to the plane of the rim, effectively enhancing the grip and preventing the liner from slipping. The liner is threaded through the central aperture, allowing the flaps to flex and create a tight seal, thereby maintaining the liner's position securely.
