Rotating Waste Receptacle Frame for Bag Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste receptacles require inconvenient and time-consuming processes to remove full trash bags, often leading to poor lifting practices due to the need to lift bags over container tops.
Innovation Solution
A waste receptacle design featuring a rotatable trash bag support frame within a stationary cabinet, allowing bags to be dropped down for removal without lifting, facilitated by a swivel assembly and a hinged cover for easy access and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional waste receptacle design is used with a stationary container top, then the structure is simple and stable, but removing full trash bags requires lifting them over the container top which is inconvenient and promotes poor lifting practices
Solution Approach 1:
The waste bag support frame is made rotatable within the outer housing about a vertical axis, transforming the static receptacle structure into a dynamic one. This allows the full bag to be rotated to a accessible position where it can be dropped down for removal without lifting over the container top, directly resolving the contradiction between ease of operation and structural simplicity.
2Ease of operation
If the waste bag support frame is made rotatable for easy bag access, then bag removal becomes convenient, but the device complexity increases due to additional rotating mechanisms
Solution Approach 1:
The waste receptacle is divided into separate functional components: an outer housing and an inner waste bag support frame that can rotate independently. This segmentation allows the rotating function to be isolated to only the necessary support frame structure, minimizing overall device complexity while achieving the desired ease of operation.
Solution Approach 2:
A swivel assembly acts as an intermediary mechanism between the stationary outer housing and the rotatable waste bag support frame. This intermediary component facilitates the rotation function with a simple bearing-based mechanism, avoiding complex motorized or linkage systems while enabling smooth bag access.
3Volume of moving object
If a rotatable waste bag support frame is implemented, then space utilization improves and compact placement is enabled, but the mechanism reliability may be reduced due to moving parts
Solution Approach 1:
The rotatable support frame enables compact placement in tight spaces by allowing vertical orientation of the bag removal path. The simple rotational movement about a vertical axis minimizes the horizontal footprint while maintaining reliability through a straightforward bearing-based swivel mechanism without complex linkages or motors.
Solution Approach 2:
The swivel assembly uses a passive bearing mechanism that requires no external power or complex control systems. The frame rotates freely and can be easily reset to its original position, providing a self-service mechanism that maintains high reliability through simplicity and ease of manual operation.

Function Achieved in This Case
This design simplifies the removal and replacement of trash bags, promoting healthier lifting techniques, reducing space requirements, and enabling convenient placement of waste receptacles in tight spaces while maintaining a compact and reliable operation.
Implementation Method 1
a swivel assembly having a top portion secured to the bottom pan of the waste bag support frame, a lower portion secured to the bottom wall of the outer cabinet, and a ring of ball bearings which supports the top portion and the lower portion relative to each other such that the top portion and the lower portion can rotate relative to each other within the outer cabinet
Implementation Method 2
a cover has a hinge, and the cover hinge utilizes a pivot support that will provide damping as the cover is opened or closed

AI summary
A waste receptacle has an outer cabinet housing and a waste or trash bag support frame that can be rotated about an upright axis to provide access to a bag held on the support frame. The support frame has a ring, on which a waste bag can be placed, spaced upwardly from the bottom of the support frame so that when the waste bag is full, it can be detached from the ring and dropped down for removal. A swivel assembly has a top portion secured to the bottom pan of the waste bag support frame, a lower portion secured to the bottom wall of the outer cabinet, and a ring of ball bearings which supports the top portion and the lower portion relative to each other such that the top portion and the lower portion can rotate relative to each other within the outer cabinet.
