Description

Device for producing an ornamental liquid feature

FIELD OF THE INVENTION

[0001] The present invention relates to a device for producing an ornamental liquid feature, in particular by colliding opposite liquid jet.

BACKGROUND OF THE INVENTION [0002] Various ornamental liquid formations- also called fountains - are known in the art, ranging from simple static fountains to complex dynamic features, the majority using water as liquid, commonly referred to as water fountains. Some water fountains use multiple jets of water which are individually discharged, forming a fountain feature as a whole but without purposely "interacting" with each other, i.e. each jet individually produces the desired effect and there is no intended direct interaction between any of the jets

[0003] A further type of water fountain, which has interacting water jets, is based on two liquid discharge means 10, 20 each producing a water jet 11, 21, the two liquid discharge means 10, 20 being configured such as to direct the two water jets 11, 21 essentially opposite to each other such as to collide and thereby form a collision surface 31. Such prior art water features are depicted on figures 1 through 3 and are the subject of various patent applications, such as US5115973A or US4002293A. As described in the latter, by slight misalignment of the axes of the two essentially opposite water jets 11, 21, the angular orientation of the collision surface 31 may be varied. The jets known by those documents are either discharged in a fixed direction or the nozzles producing the jets are arranged in a fixed mounting, only allowing the jet angle to be changed. Those types of water fountains are only able to produce a single, essentially disc-like collision surface of the water jets.

OBJECTIVE OF THE INVENTION [0004] However, these existing ornamental liquid features have in the meanwhile become so common that they no longer provide an extraordinary ornamental value. Also, the above-mentioned known ornamental liquid features based on colliding jets only produce a single essentially disc-like collision surface or at most they produce a set of distinct disc-like collision surfaces. These limitations greatly reduce the ornamental value of these features.

[0005] The objective of the present invention is thus to provide a device for producing a three dimensional liquid formation with greatly improved ornamental value, producing complex liquid surfaces. [0006] A further objective of the present invention is to provide a device which is capable of producing dynamic three dimensional ornamental liquid features of great complexity.

SUMMARY OF THE INVENTION

[0007] The above-identified objectives of the present invention are solved by a device 1 for producing an ornamental liquid feature, the device 1 comprising a plurality of discharge groups each group having a first liquid discharge means 10.1-10. n for producing a first liquid jet 11.1-11. n and a second liquid discharge means 20.1-20. n for producing a second liquid jet 21.1-21. n, wherein said first liquid jet 11.1-11. n and second liquid jet 21.1- 21. n are directed essentially opposite to each other such as to collide and thereby form a collision surface 31.1-31. n, the device further comprising a control unit 50. The liquid discharge means 10.1-10. n, 20.1-20. n of each discharge group are arranged such that and the control unit is configured for controlling the liquid discharge means 10.1-10. n, 20.1-20. n of each discharge group such as to compose the liquid surfaces 31.1-31. n, generated by the collision of the respective first liquid jets 11.1-11. n and second liquid jets 21.1-21. n of the respective discharge group, into a three-dimensional composition surface 51 essentially reproducing a virtual object 100. Thus, present invention allows to reproduce complex, three-dimensional virtual objects by a composition of liquid collision surfaces. [0008] further objective of the present invention is solved by configuring the control unit to dynamically control the discharge means such as to reproduce a dynamic virtual object, i.e. produce an animated liquid feature.

[0009] Furthermore, the objects are solved by the tech

characteristics of claims 2 to 16. The essential aspects are the extended degree of freedom for the liquid discharge means, dynamically forming said plurality of discharge groups, mapping virtual objects in an optimal way to ornamental liquid features by a control unit, enabling interaction with humans or other external input parameters, using a visual correction algorithm. [0010] The most important advantage of the present invention over the prior art is that complex, three-dimensional virtual objects may be reproduced by a composition of liquid surfaces, thereby providing a liquid feature with greatly improved ornamental and interactive value.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0012] Certain terms will be used in this patent application, the formulation of which should not be interpreted to be limited by the specific term chosen, but as to relate to the general concept behind the specific term. The term ornamental liquid feature shall be interpreted in the context of the present invention as any of the composition surfaces, irrespective of the subjective judgment whether said composition surface is ornamental. Virtual object shall be used to refer to any set of data representing an object including living beings) statically stored or dynamically generated based on external input parameters. Today, in the context of so called 3D printing, such a virtual object is alternatively called digital 3D model.

[0013] The term liquid shall be used on the following, the liquid of such ornamental features being commonly water, but the present invention also applies to other liquids or water with foreign materials added, such as surfactants (e.g. soap) to enhance the collision surface.

[0014] Preferred embodiments of the present invention shall be now described with reference to the figures. Fig. 4 shows a schematic perspective view of the device 1 for producing an ornamental liquid feature according to the present invention.

[0015] The device 1 comprises liquid discharge means 10.1-10. n; 20.1- 20. n for producing each a liquid jet 11.1-11. n; 21.1-21. n. These liquid discharge means 10.1-10. n; 20.1-20. n preferably comprise a nozzle for discharging the liquid, most preferably laminar flow nozzles to produce laminar liquid jets 11.1-11. n; 21.1-21. n. The liquid discharge means 10.1- 10. n; 20.1-20. n are grouped into a plurality of discharge groups each comprising a first liquid discharge means 10.1-10. n for producing a first liquid jet 11.1-11. n and a second liquid discharge means 20.1-20. n for producing a second liquid jet 21.1-21. n, wherein the first liquid jet 11.1-11. n and second liquid jet 21.1-21. n are directed essentially opposite to each other such as to collide and thereby form a collision surface 31.1-31. n as illustrated on figure 4.

[0016] The liquid discharge means 10.1-10. n; 20.1-20. n are either arranged in a defined pattern (such as a grid 40 shown in Fig. 5) under or around the composition surface 51 to dynamically form said plurality of discharge groups depending on the virtual object 100. Or liquid discharge means dynamically form said plurality of discharge groups depending on the virtual object 100 to be reproduced without said mentioned defined pattern but by moving their positions as explained later in this description. [0017] Illustratively shown on figure 4, the device 1 further comprises a control unit 50 operatively connected to each liquid discharge means 10.1- 10. n; 20.1-20. n. [0018] Turing now to Fig. 6 which shows a schematic perspective view of the device 1 for producing an ornamental liquid feature according to the present invention, illustrating the virtual object 100 to be reproduced by way of the example of a sailing boat. In a preferred embodiment, before and/or during controlling of the liquid discharge means 10.1-10. n, 20.1-20. n, the control unit 50 computes an optimal composition surface 51 corresponding to the virtual object 100 to be reproduced, composing the collision surfaces 31.1-31. n in an optimal way, dependent on the liquid discharge means 10.1-

10. n, 20.1-20. n of the device 1. [0019] As illustrated on figure 5 and 6, the arrangement (predefined, static or dynamic) of the liquid discharge means 10.1-10. n, 20.1-20. n of each discharge group is such as to enable the production of a three-dimensional composition surface 51 essentially reproducing the particular virtual object 100. Some predefined arrangement might be computed which enable a great variety of virtual objects 100 to be reproduced without reconfiguration. In addition, the control unit 50 controls the liquid discharge means 10.1-10. n, 20.1-20. n of each discharge group such as to compose the liquid surfaces 31.1-31. n, generated by the collision of the respective first liquid jets 11.1-

11. n and second liquid jets 21.1-21. n of the respective discharge group, into a three-dimensional composition surface 51 essentially reproducing a virtual object 100. This is achieved by controlling :

- the three-dimensional position (as illustrated on Fig. 7); and/or

- the three-dimensional orientation (as illustrated on Fig. 7); and/or

- the pressure of discharged liquid; and/or

- the flow rate of discharged liquid

of one or more of the liquid discharge means 10.1-10. n, 20.1-20. n.

[0020] In the most preferred embodiment of the present invention, the virtual object 100 is animated, the control unit 50 being configured to control the liquid discharge means 10.1-10. n; 20.1-20. n such that the three- dimensional composition surface 51 continuously reproduces said animated virtual object 100. [0021] Also shown on figure 5 is a feedback camera(s) 52 oriented towards said composition surface 51 and connected to said control unit 50. In order to provide optimal results, i.e. the composition surface 51 best resembles the virtual object 100, the control unit 50 is configured to:

- evaluate the composition surface 51 based on input from said feedback camera 52;

- assess inaccuracies of the composition surface 51 and/or undesired discrepancies between the composition surface 51 and the virtual object 100

- compute correction and/or calibration parameters corresponding to the respective liquid discharge means 10.1-10. n; 20.1-20. n so as to minimize said inaccuracies and/or undesired discrepancies;

- control the first liquid discharge means 10.1-10. n and the second liquid discharge means 20.1-20. n of each discharge group taking account of said correction and/or calibration parameters.

[0022] While not shown on the figures, the environment sensor(s) may be connected to said control unit 50, so as to record environmental variables - such as wind, atmospheric pressure, etc. - the control unit 50 being

configured to compute said correction and/or calibration parameters taking account of said environmental variables.

[0023] In order to constantly improve the control of the liquid discharge means 10.1-10. n; 20.1-20. n, the control unit 50 implements a learning and/or optimization algorithm based on an analysis of the correction and/or calibration parameters.

[0024] Fig. 7 depicts a schematic illustration of the rotational and translational freedom of a liquid discharge means 10.1-10. n; 20.1-20. n of a particularly preferred embodiment of the present invention. Depending on the complexity of the collision surface 51 to be produced, some or all of the liquid discharge means 10.1-10. n; 20.1-20. n may be implemented such as to provide all or at least some of the six degrees of freedom illustrated (three translational and three rotational). [0025] Figures 8A-8C illustrate various composition surfaces 51 produceable by the device 1 according to the present invention, figures 8B and 8C illustrating how in addition to ellipses, essentially straight edges can be produced by composing correspondingly oriented collision surfaces 31.1 - 31.3.

[0026] In a further embodiment of the present invention, the first liquid discharge means 10.1-10. n respectively second liquid discharge means 20.1- 20. n of one ore more of the plurality of discharge groups each discharge two different liquids, the compound of the two colliding liquids leading to different liquid properties of the respective collision surface(s) 31.1-31. n.

[0027] In order to provide an interactive ornamental liquid feature, an input video stream from a motion capture camera directed towards a moving object (a human and/or animal) the virtual object 100 being dynamically generated to essentially replicate and/or to react to movements of said moving object preferably in real-time.

[0028] For added ornamental value or improved visibleness, the device 1 further comprises light source(s), preferably configured such as to illuminate said collision surface(s) 31.1-31. n.

[0029] It will be understood that many variations could be adopted based on the specific structure hereinbefore described without departing from the scope of the invention as defined in the following claims.
