Flushable Portable Commode with Siphon-Based Automated Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable commodes require laborious and unsanitary manual cleaning processes, involving frequent transport of waste containers between water sources and toilet bowls, which are inefficient and embarrassing due to the handling of soiled waste, and often lack sufficient force for effective cleaning.
Innovation Solution
A flushable portable commode system that uses a human hand and foot to siphon water from a toilet bowl, creating a consistent forceful discharge to clean the waste container, eliminating the need for manual handling and providing a more dignified and efficient cleaning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning process is used, then the waste container can be cleaned, but the process is extremely laborious and requires frequent transport between water source and toilet bowl
Solution Approach 1:
The portable commode system performs self-cleaning by using its own waste container as the cleaning source. The system automatically sprays water from the waste container onto the toilet bowl and then siphons the dirty water back into the container, eliminating the need for external water sources and manual cleaning operations.
Solution Approach 2:
The patent combines multiple functions into a single integrated system: the waste container serves dual purposes as both waste storage and cleaning water reservoir, the dumping mechanism integrates with the cleaning process, and the siphoning system combines washing and waste disposal operations into one automated cycle.
2Ease of operation
If manual cleaning process is used, then the waste container can be cleaned, but it presents hazardous potential of spillage and embarrassment
Solution Approach 1:
The system automatically performs all cleaning operations without requiring the user to manually handle the waste container. The automated dumping and siphoning mechanisms eliminate the need for users to carry or tilt the container, thereby preventing spillage and associated embarrassment.
Solution Approach 2:
The patent introduces intermediate mechanisms (automated dumping arm, spray nozzle, and siphon system) that mediate between the waste container and the toilet bowl, performing the cleaning function without direct user contact with the soiled container.
3Power
If conventional siphoning is used, then water can be moved from toilet bowl, but the force is insufficient for effective cleaning
Solution Approach 1:
The system performs preliminary action by first dumping the waste container completely inverted over the toilet bowl to maximize the siphoning effect, and by pre-positioning the spray nozzle to deliver water directly onto the bowl surface before the siphoning begins.
Solution Approach 2:
The cleaning process uses periodic action through the reciprocating motion of the dumping mechanism and the cyclic operation of the siphon, creating repeated bursts of water flow that enhance cleaning effectiveness compared to continuous low-force flow.
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
The system significantly reduces the labor and embarrassment associated with manual cleaning, ensuring effective waste container cleaning without the need for manual handling, enhancing user dignity and reducing the risk of spillage and unsanitary conditions.
Implementation Method 1
lowering an intake tube from the portable commode housing so that the intake tube can be steered into the toilet bowl outlet hole
Implementation Method 2
actuating the compression chamber with a human hand and foot causing water to siphon from the toilet bowl into the chamber, and when chamber has completed receiving clean water from the toilet, the human hand and foot releases the chamber's intake activity

AI summary
Multiple apparatuses for flushing portable commodes into a conventional toilet bowl, including a push button fully automated unit that operates by a rechargeable battery. The portable commode is comprised of a waste receiving container and associated housing structure which is adapted to be seated on top of a conventional toilet. The waste container is rotated around 150 degrees and water from the interior of the toilet bowl is forcefully discharge when flushing the portable commode's waste container with electro-mechanical power to guarantee excellent cleaning. Sanitation is adapted to ensure hygienic security.
