Portable Toilet System with Stationary Docking Unit for Sanitary Waste Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with mobility issues face challenges in accessing conventional bathrooms due to distance, physical limitations, and the unsanitary and unpleasant process of handling and cleaning portable waste collection devices, which require manual disposal and cleaning of waste.
Innovation Solution
A portable toilet system comprising a mobile toilet unit with a wheelbase and a stationary docking unit equipped with a sewer port and water tank, allowing for flushing and waste disposal through a sealed communication system, eliminating the need for manual handling and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable waste collection device is used to bring the toilet near disabled persons, then accessibility is improved, but the device requires manual disposal and cleaning of waste which is messy and unsanitary
Solution Approach 1:
The invention extracts the waste disposal function from the portable toilet device itself and relocates it to a remote cleaning station. The portable unit only needs to store and transport waste, while the actual disposal and cleaning operations are performed at a separate location through automated flushing and suction systems, eliminating the need for manual handling of waste by caregivers.
Solution Approach 2:
The invention introduces an intermediary automated flushing and suction system that acts as a mediator between the portable toilet and the waste disposal system. This intermediary mechanism automatically transfers waste from the portable container to the sewer system through sealed connections, preventing direct contact and bacterial spread while maintaining the portability benefits.
2Productivity
If manual cleaning of portable toilet devices is required, then device reusability is achieved, but the cleaning process is time-consuming and unpleasant for caregivers
Solution Approach 1:
The system performs preliminary flushing actions automatically at the cleaning station before the portable device needs to be reused. The automated flush system prepares and cleans the portable toilet container in advance, eliminating the need for manual cleaning intervention and reducing caregiver time investment while ensuring the device is ready for subsequent use.
Solution Approach 2:
The portable toilet system incorporates self-service capabilities through automated flushing and cleaning mechanisms at the remote station. The device cleans and prepares itself for reuse without requiring manual intervention, transforming a labor-intensive manual cleaning process into an automated self-maintaining system that significantly reduces caregiver burden and time requirements.
3Adaptability or versatility
If the portable toilet is moved frequently to assist disabled persons, then mobility support is improved, but waste disposal becomes more complex requiring transport to cleaning locations
Solution Approach 1:
The invention segments the toilet system into two independent functional components: a portable mobile unit that provides mobility support and can be moved to assist disabled persons, and a stationary remote cleaning station that handles all waste disposal operations. This segmentation allows the mobile portion to remain simple and adaptable while the complexity of waste disposal is concentrated in the fixed station, resolving the contradiction between mobility and disposal complexity.
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 provides a sanitary, convenient, and low-maintenance solution for waste disposal, reducing the risk of bacterial spread and simplifying the cleanup process by enabling flushing and connection to a sewage system, thus addressing the challenges faced by individuals with mobility issues.
Implementation Method 1
a flush mechanism, wherein the mobile toilet unit is configured to be attached to the stationary docking unit after used by a user so that the toilet bowl is flushed with water from the water tank by activating the flush mechanism
Implementation Method 2
the toilet bowl is flushed with water from the water tank by activating the flush mechanism so as to remove waste from the toilet bowl and discharge the waste through the sewer port
Data Source
AI summary
A portable toilet system for people with mobility problems is provided. The system includes a stationary docking unit having a sewer port and a water tank with a flush mechanism, and a mobile toilet unit having a toilet bowl formed on a mobile base. The mobile toilet unit is configured to be attached to the stationary docking unit after used by a user so that the toilet bowl is flushed with water from the water tank by activating the flush mechanism so as to remove waste from the toilet bowl and discharge the waste through the sewer port of the stationary unit.
