Slotted Bar Trash Receptacle for Quick Bag Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash receptacles face challenges in efficient bag replacement, odor control, and compatibility with various types of bags, particularly those with holes, due to structural limitations and lack of portability.
Innovation Solution
A trash receptacle design featuring straight parallel bars or rods with clip mechanisms, enclosed compartments, and optional lids, allowing for easy installation and removal of bags, odor control, and compatibility with bags having holes, and the ability to be portable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional trash receptacles are used, then odor control and bag containment are improved, but bag installation and removal become difficult and time-consuming
Solution Approach 1:
The receptacle is divided into an enclosed body for odor containment and a separate accessible opening mechanism for bag operations. The lid encloses the receptacle body to contain odors, while the opening allows bag installation and removal without full exposure, resolving the contradiction between odor control and ease of bag replacement.
Solution Approach 2:
The receptacle is pre-configured with internal structures (such as bag holders or attachment points) that prepare the environment for quick bag installation. The opening mechanism is pre-positioned to allow direct access for bag replacement, enabling rapid bag changes while maintaining odor containment during the process.
2Object-affected harmful factors
If enclosed receptacles with lids are used, then odor control and bag hiding are improved, but bag replacement time increases
Solution Approach 1:
The lid enclosure is segmented with a dedicated opening that provides direct access to the bag installation area. This allows the receptacle to maintain its enclosed odor-containing structure while providing a quick-access pathway for bag replacement, reducing the time penalty associated with enclosed designs.
Solution Approach 2:
An opening mechanism acts as an intermediary between the enclosed receptacle body and the external environment. This intermediary structure allows bag installation and removal operations to occur partially within the enclosed space, maintaining odor containment while enabling faster bag replacement compared to fully enclosed designs.
3Device complexity
If standard receptacles without rods are used, then structural simplicity is maintained, but compatibility with hole-type bags is lost
Solution Approach 1:
The receptacle incorporates rods or bar structures that serve multiple functions: they provide structural support for the receptacle body and simultaneously serve as mounting structures for hole-type bags. This multi-functional design enables compatibility with various bag types (including hole-type and handle-type bags) without significantly increasing overall structural complexity.
Solution Approach 2:
The rod structures are designed to be flexible in their functionality - they can support bags in multiple orientations and configurations. The rods allow the receptacle to adapt to different bag types and installation methods, providing versatility while maintaining a relatively simple overall structure compared to specialized mechanisms for each bag type.
4Ease of operation
If portable bag racks are used, then mobility is improved, but odor control and bag containment are compromised
Solution Approach 1:
The invention merges the functions of portable bag racks (mobility and bag holding) with enclosed receptacle features (odor control and containment). The resulting structure combines the portability of racks with the enclosed body and lid of receptacles, creating a unified design that achieves both mobility and odor control simultaneously.
Solution Approach 2:
The receptacle structure serves multiple functions: it provides odor containment through its enclosed body and lid, offers bag installation and removal capabilities through its opening mechanism, and maintains portability through its overall design. This multi-functional design resolves the contradiction between portability and odor control by integrating both capabilities into a single unified structure.

AI summary
A trash receptacle comprising at least two horizontal bars, wherein the bars are structurally configured to receive and dispense garbage bags and each bar has a slot that creates opening in the bar located near a free non-affixed end of each bar, wherein each opening in the bar is configured to receive the front edge of a bag inside of the opening to prevent the bag from sliding off the bars or from collapsing inward.
