Bag Adapter Seating Frame for Generic Bags and Odor Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste disposal devices face challenges in securely attaching bags that do not meet specific size and retention feature requirements, leading to difficulties in removing filled bags and maintaining odor concealment.
Innovation Solution
A bag adapter with a seating frame and optional clamping frame that fits onto the container rim, allowing secure attachment of bags with varying dimensions, ensuring easy removal and effective odor containment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bag adapter with seating frame is introduced to support generic bags, then bag compatibility and ease of operation are improved, but device complexity increases
Solution Approach 1:
The bag adapter serves as an intermediary component between the container rim and the bag. The seating frame provides a standardized interface that accommodates various bag sizes and types, enabling easy attachment and removal without modifying the container or bag itself. This mediator resolves the contradiction by simplifying the interface between components while maintaining compatibility.
Solution Approach 2:
The adapter is designed with universal applicability to support multiple bag types and sizes through the seating frame structure. The frame can accommodate different bag dimensions while maintaining a consistent interface with the container rim, allowing one adapter design to serve multiple functions across different bag configurations.
2Adaptability or versatility
If the seating frame opening is made larger to accommodate various bag sizes, then bag compatibility is improved, but odor concealment effectiveness deteriorates
Solution Approach 1:
The adapter incorporates a collapsible or flexible sealing mechanism that dynamically adjusts to match the specific bag size being used. When a smaller bag is inserted, the sealing surface contracts to match the bag's perimeter, creating a tight seal that prevents odor leakage while still allowing the bag to be easily attached and removed.
Solution Approach 2:
The sealing surface of the adapter is designed with localized adaptability, where different portions of the sealing interface can independently adjust to match the specific bag dimensions. This allows the adapter to maintain a tight seal for odor concealment while accommodating variations in bag size through local deformation of the sealing elements.
3Reliability
If the adapter is designed to securely hold the bag, then bag retention is improved, but bag removal difficulty increases
Solution Approach 1:
The adapter employs a dynamic retention mechanism that can transition between a secured state during normal operation and a released state during removal. The collapsible or flexible sealing elements can be deliberately deformed to release the bag, allowing easy removal while maintaining secure retention during use. This dynamic behavior resolves the contradiction between strong retention and easy removal.
Solution Approach 2:
The adapter is designed with a preliminary release mechanism that can be activated to facilitate bag removal. This may involve a latch system or flexible sealing elements that can be deliberately deformed or released with a simple action, preparing the adapter for easy bag removal while maintaining secure retention during normal operation.

AI summary
A bag adapter for hanging a bag to a top container rim of a container circumscribing a container opening at least equal in dimension to the bottom bag dimension, a bag having a bottom bag dimension at most equal to a throat section of the container, the container opening being at least equal in dimension to the bottom bag dimension. The bag adapter may have a seating frame having an inner seating frame periphery circumscribing a seating frame opening, the seating frame sized to be mounted onto the top container rim such that the seating frame opening is in communication with the container opening. A kit is provided and may include the bag adapter, one or more bags. The bags may be in a roll.
