Dual-Lumen Waste Container Segmentation for Sanitary Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable storage containers for personal items face difficulties in easy disposal of waste, as they often require users to handle used items directly and may not have convenient access to waste disposal containers.
Innovation Solution
A dual-lumen portable storage and waste container with a top portion and a bottom portion, where unused items are stored in one lumen with a closed bottom and used items in another lumen with an open bottom, allowing for easy separation and disposal of waste without mixing with unused items, using reversibly secured covers and an elastic band for secure storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-compartment portable storage container is used, then the device complexity is reduced, but the ease of operation for waste disposal deteriorates because users must handle used items directly and may not have convenient access to waste disposal containers
Solution Approach 1:
The container is divided into two separate lumens: a first lumen for storing unused items and a second lumen for collecting used items. This segmentation allows waste to be collected separately without requiring users to handle unused items, improving ease of operation while maintaining a relatively simple overall structure.
2Ease of operation
If a dual-lumen container with separate storage and waste compartments is used, then the ease of operation for waste disposal is improved, but the device complexity increases due to multiple compartments and covers
Solution Approach 1:
The container integrates multiple functions into a single device: the first lumen stores unused items, the second lumen collects waste, and the common wall between them provides structural support. The removable covers allow both lumens to be sealed when needed, combining storage and waste disposal functions in one unit without requiring multiple separate containers.
3Ease of operation
If the second lumen has an open bottom for easy waste removal, then the ease of operation is improved, but the risk of spillage of unused items from the first lumen increases
Solution Approach 1:
The container is divided into two separate lumens with a common wall between them. The first lumen has a closed bottom and is sealed with a cover to prevent spillage, while the second lumen has an open bottom for easy waste removal. This segmentation ensures that unused items in the first lumen cannot spill into the second lumen even when the second lumen's cover is removed.
4Ease of operation
If a removable lower cover is used for the second lumen, then the ease of operation for waste disposal is improved, but the device complexity increases due to additional covering components
Solution Approach 1:
The container uses a single lower cover that can be removed to allow waste disposal, serving both lumens when needed. The upper cover seals both lumens when the container is being carried or stored. This approach uses minimal cover components to achieve multiple functions: sealing both lumens during transport and allowing waste removal from the second lumen when needed.
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 easy storage and sanitary disposal of personal items by keeping unused items separate from used ones, allowing for efficient emptying of waste without direct hand contact and preventing spillage of unused items during disposal.
Implementation Method 1
The lower cover is preferably formed from an elastic material and is retained on the lower end of the receptacle portion by an interference fit, and the upper cover is likewise preferably formed from an elastic material and is retained on the lower end of the receptacle portion by an interference fit.
