  • Figure 6 illustrates an embodiment wherein a plurality of smaller bags are used in conjunction with a pothole filling or patching operation in accordance with the subject application.
  • Figure 7 illustrates an embodiment wherein a non-Newtonian fluid is used in conjunction with speed bumps that are soft when a vehicle traverses at a sufficiently slow rate.
  • the subject application is directed generally to applications for practical use of non-Newtonian fluids. More particularly, the subject application teaches an embodiment wherein non-Newtonian fluids are used to patch surfaces, such as road surfaces, quickly, inexpensively, and easily.
  • Matter forms much of the tangible world around us. Matter is defined as having both a mass, and a volume. Matter exists in one or more phases, defined as a region of space wherein all physical properties of matter are generally uniform. More common phases of matter included solid, liquid or gas. Liquids or gases, which can flow, are referred to as fluids. Fluid viscosity is a measure of its resistance to gradual deformation by shear stress or tensile stress. This forms what is noted to be "thickness" in liquids.
  • Fluids comprise matter in a state that deforms, or flows, when placed under an applied shear stress, and broadly defines matter in either a liquid or gaseous phase.
  • Newtonian fluids comprise those fluids most familiar to us. Newtonian fluids are defined as fluids wherein viscous stresses, which arise from flow, are proportional to a rate of change of deformation over time. This latter property is referred to as strain. Gaseous fluids, being compressible, will behave somewhat differently than liquids, which are largely incompressible, but both result in commonly encountered fluid behavior. If one squeezes a partially inflated balloon, one readily expects the remaining balloon portion to bulge proportionately. If one squeezes an ointment tube, one expects a proportional amount to be exuded from the tube, if opened, or cause an expansion elsewhere in the tube if it is not. One does not expect any marked difference in behavior, in either instance, whether the squeezing is done slowly or at a more rapid rate.
  • NPFs non-Newtonian fluids
  • NPFs non-Newtonian fluids
  • These fluids deform or flow in accordance with a shear rate, or the rapidity at which pressure, such as a squeezed tube, is applied.
  • a first type is referred to as a shear thinning fluid.
  • fluid viscosity decreases with increasing shear stress.
  • a common example is ketchup. If a ketchup bottle is opened and inverted, it may be quite some time before the ketchup comes out. If the inverted bottle is accelerated rapidly, such as by shaking or striking upward, the ketchup comes out quite quickly.
  • a second type of non-Newtonian fluid is referred to as a shear thickening fluid, also known as a dilatant.
  • a shear thickening fluid also known as a dilatant.
  • fluid viscosity increases with increased shear stress.
  • SILLY PUTTY ® a toy product currently supplied by Crayola Properties, Inc. The malleable product deforms and stretches a large amount, provided it is stretched slowly. If it is stretched rapidly, it will snap into two parts very quickly. If it is rolled into a ball and compressed slowly, it will form a pancake shape. If it is rolled into a ball and thrown against a hard surface, it will bounce.
  • the subject application teaches an embodiment implementing non- Newtonian fluids to solve several problems.
  • the subject application teaches another embodiment wherein fluids of a sufficiently high velocity are also suitably used to solve the same or similar problems.
  • the subject application includes an embodiment for repairing or alleviating road damage with the use of a non-Newtonian fluid.
  • a sealed bag or other flexible container is supplied with a non-Newtonian fluid.
  • Such a bag is suitably implemented in connection with a temporary, or even more permanent, hole filler or patch.
  • problematic surface area 1 such as a roadway, sidewalk or other pathway having a substantially horizontal orientation.
  • a surface area 12 into which is disposed a recession or depression area, such as a pothole 14. While a pothole is used in connection with an illustrated embodiment insofar is it illustrates an intuitive, problematic situation encountered in everyday life, it will be appreciated that the subject teachings are applicable to any opening having undesirable properties relative to a surrounding surface.
  • Illustrated also in Figure 1 A is particulate debris or rough, bottom projections 16 as may be expected in many imperfect surface areas.
  • a flexible container such as a bag or other flexible container 20
  • a shear thickening non- Newtonian fluid 22 is filled, in whole or in part, with a shear thickening non- Newtonian fluid 22.
  • the bag is suitably filled with a sufficiently viscous fluid to have supportive properties corresponding to a particular support need as will be appreciated by one of ordinary skill in the art and further detailed below.
  • the bag 20 is suitably sized, or available in multiple sizes, to fit within an existing depression, such as a pothole, as illustrated with further reference to FIG. 1 C.
  • an existing depression such as a pothole
  • a depression having a substantial horizontal component of orientation will allow a bag to be received and form against a bottom portion thereof. While it may be particularly advantageous to have a volume of the depression matched by bag volume, such that an exposed surface thereof is substantially flush with surface 12, it will be appreciated that any embodiment wherein a depression is at least partially filled will supply the advantages detailed below.
  • a container such as a bag, of a suitable, non-Newtonian fluid is placed in the pothole.
  • a container such as a bag
  • a suitable, non-Newtonian fluid is placed in the pothole.
  • drivers, or professionals such as police, firefighters, or city workers suitably keep one or more bags available for use once an obstruction is discovered. They are suitably stored in a cab or truck of any vehicle.
  • a suitable, viscous fluid for pothole placement is application specific, and dictated in connection with factors including hole size, external temperature conditions, anticipated traffic weight, and surface area as will be appreciated by one of ordinary skill in the art.
  • a vehicle may have hundreds of pounds per square inch or an equivalent amount of Newtons per square centimeter to be supported given the relatively small contact area from a small portion of a tire circumference relative to a total vehicle weight supported thereby.
  • a pedestrian may only have a fraction of that weight divided over a similar surface area.
  • a vehicle travelling at a high rate of speed contacts a surface for a relatively short time as compared to a foot of a pedestrian.
  • Design choices for viscosity of common-property fluids are chosen accordingly to the specific application.
  • settlement time also of consideration for selection of fluid properties is acceptable settlement time, which settlement time may be associated with ambient temperature. If an immediate hole filling is required, that is to say, incoming traffic is imminent, then there may not be sufficient time for use of a highly viscous fluid that may take minutes to settle and conform to a pothole. Conversely, if an area is lightly travelled, or if it can be set apart for a period of time such as with a temporary barrier, then a more viscous fluid may suitably be selected. It will be appreciated that temporary installation conditions, such as recently mixed chemicals and/or addition of heat are also suitably implemented to facilitate installation.
  • a suitable, non-Newtonian fluid in one embodiment includes a mixture of corn starch and water, in any suitable, relative concentration as will be appreciated by one of ordinary skill in the art.
  • a non-Newtonian fluid is suitably realized by including one to two cups of water (approximately 0.25-0.5 liters) to 1 pound of cornstarch (approximately 0.5 kilogram).
  • Particular proportions are suitably dictated by particular application, such as road type, ambient temperature, anticipated vehicle traffic, or other external or environmental considerations.
  • suable fluids may include:
  • HEUR hydrophobically modified ethoxylated urethane with short alkyl chains at both ends of poly(ethylene oxide) (PEO)
  • Fluid is suitably contained in any water-tight device that is not rigid enough to break under stress (i.e. ceramic, glass, wood), but sufficiently pliable to transfer the force of an impact through the container's material to the non-Newtonian fluid inside.
  • a material with very robust and durable properties, while being water resistant would be used to contain the liquid.
  • a container that is not fully sealed will also function as set forth herein. Recalling that a sudden application of force to a non-Newtonian fluid will cause it to be rigid, the subject applications will still function as intended with incomplete or porous casing, either by intentional design or by damage that may be incurred during use or installation.
  • a dissolvable membrane, coupled with a biodegradable non- Newtonian fluid, such as a simple cornstarch mixture can suitably be used to accomplish the advantages of the subject application.
  • a suitable example of this material are silicone coated fabrics available from suppliers, such as CHEMFAB ® materials supplied by Saint-Gobain.
  • Other suitable materials include plastic film, such single ply or double-ply, suitably including one rough and one water resistant material would be the next best choice.
  • any suitable multi-ply container would is usable to house the non- Newtonian fluid.
  • suitable bag constituents include:
  • the patch is suitably covered for multiple reasons, such as aesthetics, protection from the elements, wear and tear, abrasion, additional containment, or theft prevention.
  • a suitable covering may be a plastic, rubber or other flexible sheeting.
  • the covering may be suitably adhered to another surface and/or the patch itself in order to secure the patch.
  • the covering is suitably designed so that the contact between the location of a force applied to the patch and the patch itself has an increased or decreased friction force provided by the covering's material structure.
  • Suitable alternative fluid ports to contain the dilatant fluid in the bag or container may be sealed using one or a combination of the following apparatus:
  • o can be crimped material or additional material attached to bag
  • o can be made from bag material or other material
  • a barrier 40 is fabricated from a viscous or non-Newtonian fluid packet wherein it is used to absorb any impact by deforming as illustrated in 40a. It will be appreciated that such is applicable in any embodiment in which a flexible material is necessary to fill a desired space and act as a shock absorber, stress reliever, or other force dispersion mechanism.
  • affixing such a packet to a garage wall suitably provides a mechanism to prevent damage from a slowly backing vehicle, while providing an abrupt stopping mechanism for a vehicle that approaches the wall too quickly.
  • Still further embodiments include:
  • Still further embodiments include:
  • Spaghetti tubing This application involves filling a thin flexible tubing with non-Newtonian fluid.
  • the tubing suitably kept on a role and extruded into large piles as needed for the repair.
  • hole 14 wherein fluid containing, flexible tubing 50 is inserted such that it fills a selected volume thereof.
  • a sending device such as cooperating rollers 52, which are suitably powered or manually operated to propagate tubing.
  • tubing is transported on medium such as spool 54.
  • Foam a highly flexible foam is soaked in the non-Newtonian fluid and used as a matrix to house the fluid. Once contained in the foam, the foam/sponge is sealed with a flexible and stretchy coating, thus keeping the mixture housed.
  • a absorptive material 60 that is suitably exposed to a dilatant fluid 62, such as that detailed above.
  • Such impregnated material is suitably encased such as is illustrated by sealed unit 64.
  • Overfilled Bag bags are made to be greatly overfilled and incorporate a bleeding valve so the excess material can drain allowing the bag to fit the hole perfectly.
  • a bag or other flexible container 70 into which fluid 72 is placed.

  • a sufficient volume of fluid 72 is extracted, suitably before or after placement of the bag 70 in the hole 14, via the valve such that an appropriate fill level is achieved.
  • Small bags Numerous small bags are suitably tossed into the hole as needed to form one large repair. With further reference to FIG. 6, illustrated is hole 14 relative to surface 12, wherein a plurality of relatively low volume bags or flexible containers 80 are placed to achieve a desired or acceptable fill level.
  • Urethane bags, made from sectioned tubes A single long tube is used to create smaller bags from. Once the tube is filled, the sections are separated simply by raising that area, allowing the material to flow away so a heat closure can be made.
  • Vacuum Sealing a method of removing excess air from the bags so they do not develop pressure under load.
  • pothole patching is a single variant of applications for the subject teachings. While any opening is contemplated, a more exhaustive listing of applications includes:
  • FIG. 7 illustrated is a fluid 80 disposed in a container, such as flexible container 82.
  • the container 82 is oriented relative to a flexible surface 84 such as to cause a projection 86 therein.
  • the container 82 is suitably disposed in an opening 88 of a volume 90 to which the surface 84 is associated.
  • This relative orientation teaches an embodiment particularly suited for orientation as a barrier having specified impact characteristics as will be appreciated from the description above when oriented in a generally vertical direction V or a speed bump when oriented in a generally horizontal direction H.
