Twisting Assembly for Odor-Sealed Waste Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste disposal devices fail to effectively contain odors from medical and industrial waste, including disposable items like gloves, gauze, and diapers, in a sanitary and odorless manner, especially in healthcare settings.
Innovation Solution
A waste disposal device with a container and a twisting assembly that forms a twist in flexible tubing upon waste insertion, using a rotation mechanism to prevent odor release, allowing multiple waste items to be encapsulated in a single bag within the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible tubing is used to form a bag for waste disposal, then waste can be contained in a sanitary manner, but odors can escape from the waste
Solution Approach 1:
The tubing is divided into multiple segments by forming twists that create separate compartments. Each twist segment acts as an independent barrier, preventing odors from traveling along the entire length of the tubing while maintaining flexible waste containment capability
Solution Approach 2:
The twist is formed in advance after waste insertion to proactively seal odors before they can escape. The rotation mechanism automatically creates the twist barrier immediately following waste placement, preventing odor release before it occurs
2Reliability
If excessive tubing is used to dispose of waste, then waste can be contained, but the device complexity and material usage increase
Solution Approach 1:
Instead of using long continuous tubing, the system uses shorter tubing segments separated by twists. The twist creates functional segmentation that allows waste containment with reduced total tubing length, as each twist compartment isolates waste without requiring extensive tubing extensions
Solution Approach 2:
The flexible tubing itself is configured to form three-dimensional twist structures that create volumetric barriers. This transforms the tubing from a simple linear container into a complex three-dimensional containment system that achieves effective waste isolation with minimal material

AI summary
Waste disposal device including a container defining a waste chamber for receiving waste, a support member arranged in the container for supporting tubing having a closed or closable front end to thereby enable formation of a bag in the container and a twisting assembly arranged in the container and defining an aperture through which the tubing passes while the twisting assembly engages with the tubing. A rotation mechanism is arranged in the container and when actuated, rotates the twisting assembly relative to the stationary support member while the twisting assembly engages with the tubing to thereby form a twist in the tubing.
