Bottom-Access Trash Receptacle with Integrated Bag Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash can systems require excessive lifting force to remove filled plastic bags due to air displacement, and lack a convenient storage solution for additional trash bags.
Innovation Solution
A trash can assembly with a tapering receptacle that allows for bottom-end removal, featuring a rotating securing mechanism and a base with a channel and sockets for easy detachment, along with a built-in compartment for storing extra trash bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If plastic bags are removed from the upper opening of the trash can, then the trash can structure is simple, but the lifting force required becomes excessive due to air displacement creating partial vacuum
Solution Approach 1:
The patent inverts the traditional trash can design by providing access to the interior volume through the bottom end rather than the upper end. The receptacle includes a bottom opening with a lip that interfaces with the base, allowing trash bags to be inserted and removed from the bottom. This inversion eliminates the partial vacuum problem that occurs when removing filled bags from the upper opening, as the tapering shape and bottom access allow air to escape more easily during bag removal.
2Quantity of substance
If additional trash bags are stored in a distant location, then the trash can capacity is sufficient, but the time and effort required to retrieve bags increases
Solution Approach 1:
The patent applies nesting by placing a storage compartment for additional trash bags within the base structure of the trash can assembly. The base includes an interior compartment that can receive and store spare trash bags, making them immediately accessible to users. This eliminates the need to retrieve bags from distant locations, reducing both time and effort while maintaining sufficient trash bag capacity.
3Stability of the object's composition
If the trash receptacle is securely mounted to prevent movement, then the mounting stability is high, but the difficulty of detecting and measuring the securing state increases
Solution Approach 1:
The patent incorporates visual indicators that change color or provide visual feedback to indicate the securing state of the trash receptacle. The base includes indicators that display different visual states (such as color changes or positional indicators) to show whether the receptacle is properly secured to the base. This makes it easy for users to detect and verify the mounting stability without complex measurement systems.

AI summary
A trash can assembly is provided. The trash can assembly provides a trash can facilitating the removal of trash through a bottom end, rather than an upper end of the trash can. The trash can assembly includes a tapering trash receptacle mountable onto a base and a securing mechanism enabling the trash receptacle to be twistably secured thereon via a plurality of notches disposed on the trash receptacle and a plurality of sockets disposed on the base. The base includes legs for immobilizing the trash receptacle when emptying and wheels for moving the trash can as desired. The base includes a watertight interior compartment sized to receive a box for storing trash bags. The trash can assembly further includes a trash bag having the same size and shape of the trash receptacle and including a length greater than the length of the trash receptacle.
