Modular Urinal Flushing Device with Separable Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinal flushing devices require significant effort for maintenance, particularly when replacing the flushing valve, and are vulnerable to vandalism due to exposed components.
Innovation Solution
A flushing device for urinals featuring a connection unit and a control unit with a secure interface that allows for easy separation and replacement, incorporating a support element, securing mechanism, and a vandal-safe design with the control unit positioned to minimize exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flushing device components are integrated into the urinal structure, then the device is more secure against vandalism, but maintenance and replacement of the flushing valve require separation of the urinal from the wall, resulting in significant effort and time consumption
Solution Approach 1:
The flushing device is divided into separate modular components: a connection unit that remains fixed to the urinal and a control unit that can be independently removed and replaced. This segmentation allows the control unit to be accessed and maintained without separating the urinal from the wall, while the integrated connection unit provides security against vandalism.
2Ease of repair
If the control unit is made easily removable for maintenance, then replacement of the flushing valve becomes straightforward, but the interface connections between pipe sections become more complex
Solution Approach 1:
The connection unit is pre-configured with connection elements and interface structures that simplify the coupling process. The inlet and outlet connections are prepared in advance with matching geometries, allowing the control unit to be quickly attached and detached without complex alignment procedures, thereby reducing interface complexity despite the removable design.

AI summary
A flushing device for a urinal comprises a connection unit and a control unit, wherein the connection unit can be fixed to the urinal and the control unit can be connected to the connection unit via an interface. The connection unit comprises a connection pipe with an inlet, for connection to a mains system, and an outlet, a flushing pipe with an inlet and an outlet for connection to a nozzle arrangement for discharging flushing water into the urinal bowl of the urinal, and a support element on which the outlet of the connection pipe and the inlet of the flushing pipe are mounted in a fixed position. The control unit comprises a support element on which are arranged at least one control element, a pipe section with an inlet and an outlet and a flushing valve, which is arranged between the inlet and outlet and has a power-supply element.
