Pivotable Wall Mobile Sanitary Unit for Compact Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile sanitary units are bulky, costly to transport, and difficult to move between use and storage positions due to their telescopic reducing systems, which are also vulnerable to vandalism and require many parts.
Innovation Solution
A mobile sanitary unit design featuring pivotable wall elements that reduce height easily, with interconnected wall parts and a pivotally connected roof, allowing for simple conversion between use and storage states, and enabling units to be stacked efficiently for transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a telescopic reducing system is used to reduce the volume of the mobile sanitary unit, then the volume in reduced state is decreased, but the complexity of moving the unit between reduced state and position of use increases
Solution Approach 1:
The patent applies dynamics by making the wall parts pivotable about a pivot axis, allowing the wall parts to be easily rotated between an extended position (position of use) and a retracted position (reduced state). This dynamic mechanism enables simple volume reduction without complex telescopic systems.
Solution Approach 2:
The mobile sanitary unit is divided into multiple separable wall parts that can be independently pivoted. Each wall part can be individually rotated about the pivot axis, allowing incremental volume reduction and simplified handling compared to moving the entire unit at once.
2Adaptability or versatility
If the entire upper construction comprising the roof and side walls is lifted to move the unit from reduced state to position of use, then the unit can be reconfigured, but the ease of operation deteriorates due to the heavy weight
Solution Approach 1:
The upper construction is segmented into separate wall parts that can be independently pivoted about the pivot axis. This allows individual wall parts to be reconfigured without lifting the entire heavy roof and side wall assembly, significantly reducing the effort required for operation.
Solution Approach 2:
The pivotable wall parts enable dynamic reconfiguration through simple rotation rather than heavy lifting. The pivot mechanism allows wall parts to be easily swung between extended and retracted positions, making the unit adaptable without requiring substantial physical effort.
3Ease of operation
If mortise and tenon joints are used for connecting wall parts, then the connection can be easily undone, but the reliability deteriorates due to vulnerability to vandalism
Solution Approach 1:
The connection mechanism parameters are changed from simple mortise and tenon joints to a more secure system involving securing means such as locks or fasteners. This maintains the ease of connection and disconnection for authorized users while providing sufficient resistance to unauthorized access and vandalism.
4Adaptability or versatility
If door panels are used in the known unit, then the unit can provide enclosed spaces, but the device complexity increases due to the large number of parts
Solution Approach 1:
The wall parts serve multiple functions: they provide structural enclosure, form the sides and roof of the unit, and can be pivoted to create enclosed spaces without requiring separate door panels. This multi-functionality reduces the total number of parts while maintaining the capability to provide enclosed sanitary spaces.

AI summary
The invention relates to a unit for accommodating at least one sanitary facility such as a toilet. The unit comprises a substantially rectangular bottom and a circumferential wall that at least partially surrounds the circumference of the bottom, wherein the unit further comprises a roof element provided on a side of the circumferential wall remote from the bottom. The interior space defined by the bottom, the circumferential wall and the roof element comprises at least one compartment for the at least one sanitary facility. Furthermore, a door element is provided for providing access to the compartment. The unit comprises a reducing system for reducing the distance between the bottom and the roof element for the purpose of thus moving the unit to a reduced state. The reducing system comprises two pivotally interconnected wall elements.
