Pivotable Urinal Wall for Underground Sanitary Facility Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public sanitary facilities with telescopically slidable housing parts may not be suitable for locations with underground obstacles like water or electricity conduits, as they can form obstacles or require significant space underground.
Innovation Solution
A pivotable urinal wall that moves between an underground rest position and an above-ground position of use, allowing the facility to be placed without obstructing traffic and minimizing underground space usage, with options for manual or automatic operation and various materials like metal or plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If telescopically slidable housing parts are used, then the facility can be placed ready for use in rapid and simple manner, but it requires significant underground space and cannot be placed at locations with underground obstacles
Solution Approach 1:
The urinal wall is made movable between above-ground and underground positions through pivoting movement. This dynamic design allows the facility to adapt between operational and retracted states, resolving the contradiction by enabling rapid deployment without requiring permanent occupation of underground space.
Solution Approach 2:
The urinal wall pivots from a vertical above-ground position to a horizontal underground position, changing its spatial orientation from one dimension to another. This dimensional transformation allows the same structure to serve different functions in different positions, eliminating the need for extensive underground space while maintaining ease of operation.
2Ease of operation
If telescopically slidable housing parts are used, then the facility can be placed ready for use in rapid and simple manner, but it cannot be placed at locations with underground obstacles like conduits
Solution Approach 1:
The pivoting mechanism enables the urinal wall to transition between above-ground operational position and underground retracted position, allowing the facility to be installed at locations with underground obstacles that would otherwise prevent placement. This dynamic adaptation resolves the contradiction between ease of operation and placement flexibility.
3Ease of operation
If the urinal wall is positioned above ground during operation, then public urination needs are met, but it may form an obstacle for traffic
Solution Approach 1:
The urinal wall dynamically changes position between above-ground operational state and underground retracted state. During non-operational periods, it pivots to the horizontal position beneath the pavement, eliminating traffic obstacles while maintaining full functionality when needed.
Solution Approach 2:
The urinal wall operates periodically, being in the above-ground position only during actual use and returning to the underground position otherwise. This periodic action minimizes traffic obstruction while ensuring availability when required.

AI summary
The invention relates to a public sanitary facility (1), comprising a housing (2) intended for placing underground. The housing is provided with means for collecting urine which are formed by a urinal wall (3) which can be mounted on the housing. The urinal wall (3) is movable from the above-ground position of use to an underground rest position, for instance by means of a pivoting movement.
