The present invention relates to a wave mitigation structure, specifically a wave mitigation structure produced via additive manufacturing.
Generally, three-dimensional (“3D”) printing is a process that extrudes material layer by layer, forming an article of manufacture from the completed extrusion layers, also known as additive manufacturing. This process is used to manufacture smaller items, such as prototypes to full scale structures. The extrusion of material from the 3D printer must have a stable surface in order for the bead to accurately and precisely match a particular model. The model refers to a digital model, such a CAD model, which a 3D printer will use to guide the extrusion layers to create the particular configuration of each required layer, eventually “printing” the entire component or components.
Many known articles of manufacture are created via precast techniques, with concrete or stone. Precast articles are construction products produced by casting concrete in a reusable mold, or “form”, which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels for tilt up construction. Alternatively, cast-in-place concrete is poured into site-specific forms and cured on site.
Wave mitigation structures can come in a variety of forms such as breakwaters, seawalls, coastal dikes, buffer blocks, and recurved seawalls. Generally, these are physical structures that are positioned in locations, allowing the particular structure to physically brace against oncoming waves. These structures can be placed underwater, at sea level, or a combination thereof. It is common for these structures to be constructed via precast techniques.
Precast manufacturing techniques however can introduce a variety of issues with the finished articles, including, but not limited to: failure in sealing joints (e.g., joints can separate from one another which can compromise and weaken the structure); potential shipping issues (e.g., weight, size, and damage-avoidance precautions); offloading and rigging concerns (e.g., the need for large commercial-scale cranes); lack of flexibility (e.g., precast articles are built to drawing specifications that may not meet the dimensions of the installation, therefore making the article useless); and, repairing spalls, or cracks (e.g., spalls can occur from poor form construction, rough removal from forms, improper storage, early removal of the structure, and poor handling methods of the structure). Typically, wave-force mitigation structures are constructed via precast manufacturing techniques and can experience any of the aforementioned issues. Thus, there is a long felt need for an improved wave-mitigation structure.
Further background information is presented in the Appendix of U.S. Patent Application No. 63/505,901.
Disclosed is an inventive concept for wave mitigation structures that is constructed via additive manufacturing; printed on site; and does not require a form.

At least one reinforcement structure may be embedded within the at least one cluster section and arranged proximate to the internal edge of the at least one longitudinal passageway, wherein the cluster section is formed by the process of 3D printing.
In some embodiments, the present invention may comprise the wave-force mitigation structure having the at least one cluster section having the at least one longitudinal passageway, the longitudinal passageway having at least one center point, the at least one center point defined by one of: the imaginary circumference; and, the internal edge of the at least one longitudinal passageway, the cluster section having the plurality of apertures in fluid communication with the at least one passageway or longitudinal openings disposed between adjacent longitudinal passageways. The at least one reinforcement structure may be embedded within the at least one cluster section and arranged proximate the internal edge of the at least one longitudinal passageway.
In other embodiments, the present invention may generally comprise the wave-force mitigation structure, including the at least one cluster section having the at least one external body and the at least one internal body arranged with the external body, each of the at least one external body and the at least one internal body having the plurality of apertures arranged therein or longitudinal openings disposed between adjacent longitudinal passageways, and the at least one longitudinal passageway arranged within the at least one internal body, the longitudinal passageway having the at least one center point, the at least one center point defined by one of: the imaginary circumference; and, the internal edge of the at least one longitudinal passageway, wherein at least some of the plurality of apertures are in communication with the at least one passageway or longitudinal openings are disposed between adjacent longitudinal passageways.
In other embodiments, the present invention may have alternative design configurations substantially similar to those disclosed in at least one of U.S. Design Pat. Nos. 29/919,935, 29/919,935, and a combination thereof.
These and other objects, features, and advantages of the present invention will become readily apparent upon a review of the following detailed description, in view of the drawings and appended claims.
Various embodiments are disclosed, by way of example only, with reference to the accompanying schematic drawings, in which corresponding reference symbols indicate corresponding parts, in which:
At the outset, it should be appreciated that like drawing numbers on different drawing views identify identical, or functionally similar, structural elements. It is to be understood that the claims are not limited to the disclosed aspects.

It is also understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to limit the scope of the claims.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this disclosure pertains. It should be understood that any methods, devices or materials similar or equivalent to those described herein can be used in the practice or testing of the example embodiments. As such, those in the art will understand that in any suitable material, now known or hereafter developed, may be used in forming the present invention described herein.
It should be noted that the terms “including”, “includes”, “having”, “has”, “containing”, and “contains”, are to be interpreted as substantially synonymous with the terms “comprising” and/or “comprises”.
It should be appreciated that the term “substantially” is synonymous with terms such as “nearly,” “very nearly,” “about,” “approximately,” “around,” “bordering on,” “close to,” “essentially,” “in the neighborhood of,” “in the vicinity of,” etc., and such terms may be used interchangeably as appearing in the specification and claims. It should be appreciated that the term “proximate” is synonymous with terms such as “nearby,” “close,” “adjacent,” “neighboring,” “immediate,” “adjoining,” etc., and such terms may be used interchangeably as appearing in the specification and claims. The term “approximately” is intended to mean values within ten percent of the specified value.

In some embodiments, before first outer layer 10 cures, mesh 21 is added to sub-structure portions 20a-20f such that mesh 21 covers passageway section 13 and stirrup 22 is added to the exposed surface of external body 11. Stirrup 22 is a reinforcement structure and may be comprised of a rebar—either metal, plastic, polymer, combinations thereof, or other like material. Stirrups 23 are also added to side faces 16b and 17b of bases 16 and 17, respectively.

Generally, oscillating water columns (OWC) use an air turbine housed in a duct well (chamber 101f and conduit 101g) above the water surface. Chamber 101f of mitigation structure 100 shown in
Additional illustrations and information regarding the turbine are detailed in the Appendix of U.S. patent application Ser. No. 63/505,901.
In operation, the turbine within conduit 101g is rotated in a first direction (about its axis) within conduit 101g when the water level rises within chamber 101f (due to the water creating air pressure within chamber 101f and thereby forcing the air past the blades) and when the water level recedes within chamber 101f, the turbine within conduit 101g is rotated in a second direction (due to the receding water creating opposite air pressure within chamber 101f and thereby forcing the air part of the blades in the opposite direction).

Mitigation structure 200 is ideally arranged to be placed off-shore and its arrangement forces water, moved by tidal current, waves, etc., to be passed through at least one of: 1. At least one of passageways 210a, 210b, and/or 210c; 2. Plurality of apertures 206; 3. Plurality of apertures 206a; and/or, a combination thereof, thereby decreasing and/or dissipating the force associated with various water movements.

In some embodiments, passageway 312 comprises at least one center point defined by an imaginary circumference defined by the internal edge of internal body 306. In other embodiments, passageway 312 comprises center points CP1, CP2, and CP3 which are defined by imaginary circumferences C1, C2 and C3, respectively. Imaginary circumferences C1, C2 and C3 are defined by the internal edge of internal body 306. In a preferred arrangement, plurality of apertures 310 are in communication with plurality of apertures 314, whereas plurality of apertures 314 are in communication with passageway 312. In other arrangements, base 308 may comprise a plurality of apertures therein, which apertures may be in communication with some of plurality of apertures 314. The apertures, e.g., 310 and/or 314, are not intended to be restrictive to any specific shape and thus, may be formed in a variety of different geometrics, e.g., substantially square, triangular, irregular polygonal, tapered or non-taper, a combination thereof, and/or the like.
Mitigation structure 300 is arranged in a manner where a printer device, which prints the structure, does not need to execute multiple “lifts”. Lifts occur when the printer device cannot continually print, therefore needing to shut off and reposition a nozzle to begin printing again. As shown in

It should be noted that the structure arrangement of mitigation structure 300 may be applied to mitigation devices 100 and/or 200, i.e., singular component external body and singular component internal body.
The following description should be taken in view of
The inventive concept mitigates wave energy that may be described in terms of wave vectors or wavevectors used to describe a wave, with a typical wave vector unit being cycle per a distance such as a meter in which further there is a magnitude and direction. The magnitude is typically the wavenumber of the wave (inversely proportional to the wavelength), and its direction is perpendicular to the wavefront. In isotropic media, this is also the direction of wave propagation. A closely related vector is the angular wave vector (or angular wavevector), with a typical unit being radian per meter. The wave vector and angular wave vector are related by a fixed constant of proportionality, 2π radians per cycle and wave mitigation may involve angular wavevectors, radial wave vectors, and linear wave vectors or by what other terms may be used to describe wave vectors.
The wave-force mitigation structure as described can have at least one perforated cylindrical cluster section adapted to be parallelly abutted to at least one additional perforated cylindrical cluster section by substantially planner outer surface portions of the perforated cylindrical cluster sections wherein at least one or more of water and air may pass through and between the at least one perforated cylindrical cluster sections. Such abutment allows the elimination of excess space and geometric arrangements such as assuring perforation is lined up or are deliberately misaligned so as to affect dissipation of wave energy. Inner surface portions and the substantially planner outer surface portions of the perforated cylindrical cluster sections are adapted to at least partially dissipate wave energy from at least one primary wave vector into a plurality of smaller wave vectors, typically by such ways as reflecting waves, restricting wave passage, changing wave magnitude, changing wave frequency, creating turbulence, absorbing energy, and other ways by which wave energy can be dissipated when compared to arriving wave vectors. The at least one perforated cylindrical cluster section is formed and formable from a plurality of 3D printed, substantially planar layers disposed orthogonal to a longitudinal center axis of each perforated cylindrical cluster section wherein each layer can be assigned a unique plane parallel to the plans of preceding or following printed layers.
The wave-force mitigation structure cylindrical cluster section may further include at least one perforated inner cylinder disposed within a perforated polygonal outer cylinder. The perforated polygonal outer cylinder may further be hexagonal such that the at least on cylindrical cluster sections may be assembled in parallel rows to, cross-sectionally, appear as a honeycomb-like structure.
It should be noted that the perforations and/or apertures may be formed post-printing by any means capable of boring, drilling, cutting, or otherwise creating the plurality of perforations and/or apertures within the wave-force mitigation structure.
Alternatively, lintel-like means may be placed during the printing process of the wave-force mitigation structure at the respective locations of each of the plurality of perforations and/or apertures. Generally, a lintel is a beam, support structure, filling, matrix unit, which placed across openings in buildings like doors, windows, etc., to support the load from the structure above, i.e., to support the load of the extruded material from a 3D printing system or 3D printer—as shown in the Appendix of U.S. Patent Application No. 63/505,901. These lintels may be permanent structures, or temporary structures which are removed after the printing process is completed and material has cured.
However, the present inventive concept may use an inflatable lintel-like structure, which is generally inflated during the printing process to fill a location in the structure to be printed, thereby creating, voids, apertures, through-bore, spaces, gaps, etc., which extruded material from the printing system or printer may then print over. The inflatable structure is then deflated and removed from the completed and cure structure, leaving the desired voids, apertures, through-bore, spaces, gaps, etc., within the structure. In one embodiment, the inflatable lintel structure generally will include a main body and at least one sub-body extending therefrom. The main body and the sub-body have at least one internal cavity which is arranged to be inflated via a gas, i.e., air, oxygen, etc. The inflatable structure will be arranged such that it may support extremely high PSI within the internal cavity to maintain the shape of at least: the main body; and at least one sub-body, such that the weight of printed material thereon, will not collapse, or otherwise deform, the shape and configuration of the main body and at least one sub-body (if any). See Appendix, U.S. Patent Application No. 63/505,901.
Lastly, one having ordinary skill in the art would appreciate that although the present invention is best implemented by means of additive manufacturing, e.g., 3D printing, and particular embodiments are optimized for such manufacturing means, as discussed supra, methods of constructing the present invention are not limited to 3D printing and may be implemented by other known techniques, e.g., dry-casting, wet-casting, and other building techniques now known or hereafter developed. The is same true with respect to materials selected to form the present invention, and those in the art will understand that any suitable material, now known or hereafter developed, may be used in forming the present invention described herein.
The shown and described embodiments are merely exemplary and various alternatives, combinations, omissions, of specific components, or foreseeable alternative components, understood by one having ordinary skill in the art, described in the present disclosure or within the field of the present disclosure, are intended to fall within the scope of the appending claims.
It will be also be appreciated that various aspects of the disclosure above and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
