Device to open and close trash bin cabinet doors in small spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash collection apparatuses within cabinet housings require manual operation and have complex constructional features that hinder the sliding mechanism and require manual opening of the lid, causing inconvenience to users.
Innovation Solution
A trash collection apparatus with a waste receptacle that moves forward and opens its lid when the cabinet door is opened, allowing for automatic access and retrieval back to its original position while closing the lid and door simultaneously, utilizing a bin support with a spring member and guiding assembly for sliding along a rail, and a roller on the lid for automatic opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the waste receptacle is placed inside the cabinet, then space in the kitchen is saved and people can move around without obstruction, but users have to bend down to access the waste receptacle to place or clear garbage
Solution Approach 1:
The waste receptacle is designed to be dynamically movable between a stored position inside the cabinet and an accessible position outside the cabinet. The bin support assembly with rollers allows the receptacle to slide along rails when the cabinet door opens, automatically bringing it to an accessible position without requiring the user to bend down.
2Device complexity
If manual operation is used to open and close the cabinet door and lid, then the mechanism is simple, but it causes inconvenience to users
Solution Approach 1:
The system is designed to automatically open the waste receptacle lid and move the bin support assembly when the cabinet door is opened, without requiring manual operation. The spring member provides automatic return to closed position, and the guiding assembly coordinates the synchronized movement of door, lid, and bin support, enabling hands-free operation.
3Ease of operation
If complex constructional features are added to enable automatic opening, then ease of operation improves, but the sliding mechanism is hindered
Solution Approach 1:
The automatic opening mechanism is segmented into independent functional components: spring members for providing opening force, rollers for smooth movement along rails, guiding assemblies for coordinated motion, and latch mechanisms for holding positions. This segmentation allows each component to perform its specific function without interfering with the overall sliding mechanism.
4Ease of operation
If the waste receptacle is placed in a corner of the kitchen, then it is easy to access, but it becomes an obstruction when not being used
Solution Approach 1:
The waste receptacle transitions from a static corner placement to a dynamic position that moves between stored and accessible states. When not in use, the spring member keeps the bin support assembly retracted inside the cabinet, clearing the kitchen space. When needed, the cabinet door opening automatically moves it to an accessible position, eliminating the need for permanent corner placement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables hands-free operation, simplifies access to the trash receptacle, and utilizes available space efficiently without obstructing the cabinet's pipes or drainage systems, providing a convenient and space-saving solution for waste management.
Implementation Method 1
a bin support mounted to a spring member and the spring member is mounted to a rail provided at bottom of the cabinet housing

AI summary
A trash collection apparatus useable in kitchens, bathrooms, bedrooms etc. is disclosed. The trash collection apparatus comprises a cabinet housing having sidewalls. The trash collection apparatus comprises a door hingedly mounted to a sidewall of the cabinet housing. The door comprises a frame member at the bottom. The trash collection apparatus comprises a bin support mounted to a spring member and the spring member is mounted to a rail provided at bottom of the cabinet housing. The bin support comprises a guiding assembly mounted to the frame member. The trash collection apparatus comprises a trash receptacle placed on the bin support and a lid hingedly mounted to the trash receptacle. The bin support carrying the trash receptacle is slidable along the rail with the help of the spring member. While the bin support is being slid, the lid is operated to provide access to the interior of the trash receptacle or to cover the trash receptacle and the door is operated between an open and closed position.
