Outdoor sanitation system including an urinal unit for temporary placement and frequent transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitation systems, such as the Kros, Uriclean, and PEE6 urinal units, suffer from inefficient transport due to their bulky and robust structures, which hinder efficient transportation and are prone to vandalism or require time-consuming disassembly.
Innovation Solution
A sanitation system with a urinal unit featuring a unit body and removable urinal unit accessories that fit snugly into the urinal compartments, reducing dead space and allowing for compact transport assemblies, and incorporating lock members for stability during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a robust one-piece upstanding wall structure is used to prevent vandalism, then reliability is improved, but transport efficiency deteriorates due to bulky configuration
Solution Approach 1:
The upstanding wall is divided into multiple separate partition walls that can be individually removed. Each partition wall is a separate component that can be detached from the base portion, allowing the urinal unit to be disassembled for efficient transport while maintaining robust protection when assembled.
2Productivity
If a demountable structure with separate partition walls is used to improve transport efficiency, then transport efficiency is improved, but reliability deteriorates due to vulnerability to vandalism and unauthorized demounting
Solution Approach 1:
The structure is segmented into a base portion and multiple separate partition walls that can be easily assembled and disassembled. This segmentation enables efficient transport by allowing the partition walls to be removed and stacked, while still providing robust vandalism prevention when the partition walls are installed on the base portion.
3Productivity
If partition walls are made demountable to reduce transport volume, then transport efficiency is improved, but device complexity increases due to assembly and disassembly requirements
Solution Approach 1:
The urinal unit is segmented into a base portion and multiple independent partition walls that can be easily attached and detached. This simple segmentation reduces transport volume by allowing components to be disassembled and compactly stacked, while keeping device complexity low through straightforward assembly and disassembly operations.
4Productivity
If a telescopically arranged upper portion is used to reduce transport volume, then transport efficiency is improved, but reliability deteriorates due to vulnerability to unauthorized lowering
Solution Approach 1:
Instead of a telescopic mechanism, the structure is segmented into a base portion and separate partition walls that can be removed and stacked. This segmentation achieves transport efficiency by reducing transport volume through disassembly, while improving reliability by eliminating the vulnerability of telescopic mechanisms to unauthorized lowering.
5Adaptability or versatility
If accessories are transported separately from the urinal unit, then adaptability is improved, but transport efficiency deteriorates due to increased transport volume
Solution Approach 1:
The accessory is designed to be nestable within the urinal compartment when not in use. The accessory can be placed inside the compartment space of the urinal unit, allowing both the urinal unit and accessory to be transported together in a compact configuration, thereby improving transport efficiency while maintaining adaptability for separate deployment at the destination.

AI summary
A sanitation system and a method for transporting such a sanitation system includes a urinal unit which has a unit body having at least one urinal compartment and at least one urinal unit accessory which has an accessory body. An outer shape of the accessory body is adapted to an inner shape of the inner compartment of the unit body. A close fit between the urinal unit accessory and the inner compartment of the unit body is obtainable to provide a stable transport assembly. Preferably, the urinal unit is provided with a compartment lock member and the urinal unit accessory is provided with a cooperating accessory lock member.
