Rubbish Container Self-Cleaning Device Using Tilt Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for disinfecting large household rubbish containers are inefficient, as they often require manual operation, result in excessive fluid usage, and fail to effectively clean the bottom surfaces due to fluid distribution issues, particularly when the containers are partially filled.
Innovation Solution
A self-contained cleaning or disinfecting device within the rubbish container that forms and spreads a dose of disinfecting fluid after tilting and returning to the normal position, ensuring effective cleaning of the bottom surface without external aid, with a dosing element connected to a fluid reservoir and pipes for controlled fluid distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If fluid dispensing is linked to lid actuation, then automatic cleaning is achieved, but fluid is wasted when container is filled and cleaning efficacy is reduced
Solution Approach 1:
The system performs preliminary action by emptying the container before dispensing cleaning fluid. The tilt sensor detects when the container is empty, triggering fluid dispensing only at the appropriate time when the container is ready to be cleaned, preventing waste and ensuring efficacy.
2Extent of automation
If fluid is dispensed at opening and closing phases, then automatic actuation is achieved, but cleaning of bottom surface is ineffective when container is filled
Solution Approach 1:
The system ensures the container is emptied before cleaning by using a tilt sensor to detect the empty state. Only when the container is confirmed empty does the system dispense cleaning fluid, guaranteeing that the bottom surface is accessible and cleaning is effective.
3Manufacturing precision
If manual cleaning is performed, then thorough cleaning is possible, but significant time and effort are required
Solution Approach 1:
The container performs self-cleaning through an automated system. The tilt sensor detects when the container is empty and triggers a pump to dispense cleaning fluid internally, eliminating the need for manual cleaning operations while maintaining thoroughness.
4Ease of operation
If spray system is positioned at top of container, then actuation is simplified, but fluid does not reach bottom when container is filled
Solution Approach 1:
The system ensures the container is emptied before fluid dispensing. The tilt sensor detects the empty state, triggering pump activation only when the bottom surface is accessible, ensuring proper fluid distribution regardless of the spray system position.
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
This solution enhances the cleaning efficacy of the container by ensuring all fluid is used for cleaning the bottom, reducing waste, and providing an economical and reliable method for maintaining cleanliness without external devices.
Implementation Method 1
forming a dose of fluid inside the container when it is tilted into the rubbish-discharge position and spreading the dose of fluid inside the container when the container has been returned to its normal position of use

AI summary
In at least one embodiment, a container includes an opening for the deposition of rubbish therein and a cleaning or disinfecting device configured to provide a cleaning or disinfecting fluid inside the container. The cleaning or disinfecting device includes a delivery device inside the container configured to deliver a dose of fluid after an inclination of the container and then returning the container to a normal position of use.
