Problem
Existing washing devices consume high amounts of energy and water, are not easily installable in existing buildings, and pose risks for the spread of infectious diseases due to waterborne pathogens.
Innovation Solution
A washing device that increases fluid pressure for efficient low-flow water dispensing, allowing for reduced energy and water consumption, decentralized heating, and integration with existing infrastructure, while preventing the spread of infectious diseases by maintaining cold water systems until use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional shower head with high water throughput is used, then a pleasant shower experience is achieved, but water consumption and energy consumption increase significantly
Solution Approach 1:
The patent changes the pressure parameter from conventional low-pressure spray to high-pressure spray (up to 50 bar). This parameter change allows the use of very fine nozzle openings (0.1-1 mm) that create excellent atomization and shower quality while reducing water throughput to 0.1-5 liters per minute, thus resolving the contradiction between shower experience quality and water consumption
2Temperature
If a heater is installed in the shower sprinkler to heat water directly, then warm water is provided, but a large amount of heating power is required
Solution Approach 1:
The patent reduces the water throughput parameter to very low values (0.1-5 liters per minute). This parameter change allows the heating device to provide warm water with much lower heating power requirements, making it feasible to install heating directly in the shower sprinkler without requiring large amounts of power
3Manufacturing precision
If a pump is used to increase water pressure to high levels, then atomization quality improves, but the apparatus cannot be connected to water supply mains due to high entry pressure
Solution Approach 1:
The patent performs preliminary action by storing water in an elevated storage tank (cistern) positioned 3-10 meters above the apparatus. The gravitational potential energy of the stored water provides the high pressure (15-50 bar) needed for atomization, eliminating the need for a pump and allowing direct connection to water supply mains while maintaining excellent atomization quality
4Ease of operation
If warm water systems are used in showers, then comfortable washing is achieved, but the risk of spreading infectious diseases increases
Solution Approach 1:
The patent stores cold water in an elevated tank and only heats water immediately before use through the heating device integrated in the shower sprinkler. This preliminary storage of cold water eliminates the risk of infectious disease spread associated with warm water systems, while the integrated heater provides comfortable warm water when needed
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 device provides a pleasant washing experience with reduced water consumption, efficient energy use, and minimized risk of disease transmission by using decentralized heating and maintaining cold water systems until use.
Implementation Method 1
at least one delivery device (6) for increasing the fluid pressure to an operating pressure of the outlet (1), before spraying
Implementation Method 2
the jets from two nozzles of a pair impact one another and create droplets by way of this
Implementation Method 3
spraying fluids with a low flow rate and under a high pressure... The sprayed fluid as a rule is water or a water-based mixture
Implementation Method 4
a heating device (5) for heating the water... from a cold water supply (11) to a dispensing temperature

AI summary
A washing device for dispensing water in the sanitary field, in particular in a shower or a sink, including an outlet for spraying fluids with a lower throughput rate, as well as a delivery device for increasing the fluid pressure before the spraying. The washing device includes a heating device for heating the water. Atomization is accomplished by way of a fluid jet hitting an obstacle with a high relative speed. Thereby, the obstacle may be a moved or stationary solid body or at least one further fluid jet. Spraying is accomplished by way of the outlet including at least one nozzle set with at least two nozzles, for producing impacting fluid jets and for atomizing the fluid.
