Solution Overview
Problem
Sanitary cubicles with complex flushing mechanisms have high production costs and reliability issues, necessitating a simpler and more reliable flushing mechanism.
Innovation Solution
A sanitary cubicle with a pivotable entrance door, a piston arrangement pump device, and a reservoir, where the connecting element is a linear or essentially linear strut that bends to transmit forces efficiently, allowing for effective suction and pressurization of flushing liquid between the reservoir and sanitary units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex flushing mechanism is used to improve hygiene in sanitary cubicles, then flushing capability is improved, but production costs increase and reliability decreases
Solution Approach 1:
The patent extracts the complex flushing mechanism from traditional sanitary cubicles and replaces it with a simplified piston-based system. The piston device is taken out from conventional pump designs and integrated directly with the entrance door mechanism, eliminating the need for separate complex flushing systems while maintaining reliable flushing capability.
Solution Approach 2:
The entrance door serves multiple functions: it provides access to the sanitary cubicle and simultaneously acts as the actuating mechanism for the flushing system. The piston device is integrated into the door structure, making the door both a functional barrier and a flushing trigger, thereby reducing overall system complexity while improving reliability.
2Device complexity
If a piston arrangement with connecting element is used to simplify the flushing mechanism, then device complexity is reduced, but force transmission reliability may worsen
Solution Approach 1:
The connecting element is designed with a curved or arc-shaped geometry rather than a straight rigid connection. This curvature allows the connecting element to flex and accommodate the pivoting motion of the entrance door while maintaining continuous force transmission to the piston, ensuring reliability despite the simplified structure.
Solution Approach 2:
The connecting element's physical parameters (shape, flexibility, material properties) are optimized to transform the rotational motion of the door into linear piston movement. By changing the geometric parameters of the connecting element, the system achieves reliable force transmission through a simplified mechanical linkage that adapts to the door's pivoting action.
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 solution provides a simple, reliable, and cost-effective flushing mechanism with high hydraulic pressure for effective sanitation, ensuring hygiene standards are met with low maintenance and ease of operation.
Implementation Method 1
the connecting element can be bent at least in regions, preferably in the form of an arc, when the entrance door is pivoted from the closed position (locked position) into the open position
Implementation Method 2
when the entrance door is pivoted from the open position into the closed position, a compressive force is exerted on the piston via the connecting element, so that the piston is pressed in the direction of a front face end of the piston housing and flushing liquid is pressed out of the outlet opening to the sanitary unit

AI summary
The cubicle has a connector (11) connected with a piston (18) at an end. Tension force is exerted on the piston while pivoting an entrance door (8) from an open position into a closed position such that the piston is pulled along direction of a rear-side end (19) of a housing. Pressure force is exerted on the piston while pivoting the door from the open position into the closed position over the connector such that the piston is pressed along direction of a front-side end (22) of the housing and flushing liquid is pressed from an exhaust opening to a sanitary unit e.g. toilet (10). The connector is a linear connection strut and made of fiber reinforced plastic. The sanitary unit is urinal and wash basins.
