- the bladder tank(s) 114 recoil back under the integrated shelter 100 using integrated stainless steel coils, and is also stored automatically beneath the platform 106 , which protects it against damage and soiling.
- Using the water supply system 104 makes it is necessary to calculate the tank volume as a function of daily/monthly rain water availability at the site and the water consumption of four persons per shelter so that adequate water is available. An example calculation follows:
- Each integrated shelter 100 also has an electrical system 102 that generates and supplies electricity for lights, such as light emitting diodes (LEDs) 142 mounted in the shelters to illuminate the interior living space of the shelters, for small cooking equipment and for other electrical devices.
- the shelters 100 each have a size of approximately 1429.39 mm ⁇ 424.40 mm and are rated for a power of 32 watts and an operating voltage of 16.5 volts.
- the plastic photovoltaic film serves as the front enclosure of the shelter and provides privacy for the dwellers.
- the generation of electrical energy begins at the beginning of the day when the front shelter enclosure is opened to a vertical canopy and supported by fiberglass rods or local materials, such as bamboo sticks.
- the photovoltaic plastic sheets or panels 144 also may serve as a cover against rain, and as a semi-private, intermediate space between two shelter modules facing each other (see FIG. 9 ). In this space, school can be held, community meetings find a protected space and supplies for first aid shelters can be stored.
- the radiation exposure of the shelter walls to the cardinal directions of the sun causes the photo voltaic panels 144 to be only oriented as a horizontal roof surface facing the zenith.
- the canopy structures are oriented independently of the orientation of the individual articulated shelters.
- each photovoltaic panel 144 is delivered as Direct Current power (DC). It is assumed that the dwellers in the shelter units 100 use electricity for cooking for a period of 2 hours/day.
- An electrical storage device or storage battery 146 such as a car battery, of 13.5 kWh is therefore necessary, especially for overcast and night time conditions.
- the lighting devices may be connected to the battery 146 or to at least one of the photovoltaic panels 144 .
- the above integrated shelter 100 provides transportable, convenient, safe and durable temporary housing to people that are stranded and homeless due to natural disasters and other disasters. As a result, the devastating effects of such disasters on those people are lessened as they try to rebuild their lives.

- Referring now to
FIGS. 1-11 , the present invention provides an integratedportable shelter 100 that provides modularity, ease of transportation and assembly, complete autonomous generation and supply of electric energy, and harvesting of water to aid people that are stranded and homeless after natural disasters and other types of disasters. - The integrated
shelter 100 is designed to act as temporary housing placed in the direct vicinity of homes affected by a disaster. In order to be assembled and placed as close as possible to peoples familiar living quarters, social settings and infrastructure, the shelter is constructed to be a highly flexible, multi-purpose system that is easy to handle and transport. - The structure of the integrated
shelter 100 includes a structural fiberglass tube bundle with integrated steel-cable-reinforced framing support elements, wall and roof enclosure materials, a bladder water tank for rainwater harvesting, water purification, and a thin-film photovoltaic or solar element for off-grid power generation, which is transportable in required quantities to areas affected by disasters. - Upon deployment to the particular areas or sites, the individual integrated
shelters 100 can be transported and erected by two people without the use of tools. Also, the integratedshelter 100 has an autonomouselectrical system 102, which provides electrical energy for lighting of the shelter and other equipment, and awater system 104 for harvesting and storing water for human consumption in areas which have lost the ability to provide power and water due to destroyed or damaged utility grids. - A single integrated shelter, unit or
module 100 provides rapid shelter for approximately four adult people for short term or semi-permanent use. The number of people that can live in a shelter unit varies based on the size of the unit and the size of the people staying in the unit (i.e., adults, adults and children, etc.). The integratedshelters 100 can be arranged in flexible setups to accommodate larger space needs, to respond to local conditions or to reflect local cultural habits. - Each integrated
shelter 100 is provided as a light-weight, compact shelter system kit. The materials and shape of the shelter are capable of effectively harvesting rainwater for purification and human consumption. Also, the generation of electrical energy for lighting purposes is provided through the use of one or more integrated thin-film photovoltaic panels. For warmer climates, the shelter allows for climatically responsive natural cross-ventilation without mechanical means or mechanical devices. To further minimize heat gain during the day, the integrated shelters are designed to be compact having a surface-to-volume ratio of 1.2. The compact design also helps to minimize heat loss at lower ambient air temperatures that typically occur at night. - To facilitate effective under-floor natural ventilation, each integrated shelter has an elevated or raised
dwelling platform 106. Theelevated platforms 106 also provide a safe area of inhabitation by protecting against animals, adverse soil conditions, moisture and uneven ground conditions. Further, the elevated design reflects various global dwelling customs. Another feature of the integratedshelter 100 is that it is integrated as a compact, easily transportable fiberglass tube bundle, which provides the structural framework, autonomous water supply system, photovoltaic energy generation, and space for storage of all necessary elements of its canopy structure. - Besides the main fiberglass tube bundle, the secondary structural elements of the integrated shelter include bamboo, wood and other similar materials that can be readily replaced by local materials.
- Furthermore, the
roof 108 andside walls 110 of the integratedshelter 100 consist of double-skin, inflatabledouble chamber cushions 112, which reduce solar energy heat gain, and prevent energy loss. Theroof 108 also includes funnels (not shown) that collect rainwater into a shelter-integrated water storage tank orbladder tank 114 typically mounted underneath the shelter. Thewater storage tanks 114 may also be mounted on any other suitable part of the shelter or outside of the shelter if needed. - Since lightness and transportability is one of the primary design features of the integrated
shelters 100, the shelters are secured to the ground using retrievable, reusable earth anchors (not shown). A steel driving rod for the placement of the anchors is integrated into the fiberglass support structure. - Once the integrated
shelter 100 is transported to a site it can be unfolded and put to use without using heavy equipment or tools. The tent-like structure is easy to set up and can be transported, unfolded, erected, joined together, and manually inflated by as little as two people. -
Single shelters 100 can be either stand-alone structures, or joined together with other shelters to form larger, continuous bi-articulated dwelling units for special uses, such as for first aid, education, or community functions. With the help of a flexible intermediate connector 116 (accordion joint, bi-articulation connectors) shown inFIGS. 5-7 , a series of connected shelters are able to be adapted to the local conditions of a site, such as trees, rocks, and other obstacles and obstructions. As shown inFIGS. 1 and 14 , the flexible connector defines a pair of recesses 119 and allows for the arrangement of theintegrated shelters 100 to form circular arrangements, semi-circular arrangements, courtyards, and other customary dwelling patterns warranted by the local cultural tradition. At least oneconnector 116 is included in each of the shelter kits. A ground support orleg 117 is rotatably connected to eachconnector 116 and rotate from a storage position to a support position as shown inFIG. 7 . Thelegs 117 allow theshelter 100 to stand securely on the ground so that theplatform 106 is raised above the ground. It is also contemplated that thelegs 117 may be non-rotatably connected to theconnectors 116 by friction fit or other suitable connection method. - Each
integrated shelter 100 includes a structure formed by aprimary support system 118 forming the base or support frame, asecondary support system 120 includingplatform 106, and aroof 108 supported by the secondary support system. - The
primary support system 118 includes a tubular base frame or support frame made of lightweight, high-strength tri-modular group offiberglass tubes 122 that are resin reinforced at major bearing intersections. Thefiberglass tubes 122 include afront support beam 124, arear support beam 126, and a verticalphotovoltaic mast 128. Fiberglass is utilized since it is stronger than aluminum, which is commonly used for such shelters. Also, fiberglass is lighter than aluminum and can be repaired when needed. The fiberglass tubes are formed in standardized molds and provide a space-saving bundle for easy transport of the shelter. - The
secondary support system 120 includes flexible, hollow fiberglass poles orrods 130 that form the frame or support for theroof 108 andfront wall 111. Therods 130 are connected to thebase tubes 122 usingconnectors 116, where the rods and base tubes are inserted in the recesses 119 by using a friction-fit. Thehollow rods 130 contain a stainless steel leader wire (now shown) to allow for easy assembly. - The roof or
canopy 108 is positioned on and secured to thesecondary support system 120 and is made of a double-skin, flame retardant, neoprene-coated nylon, such as DuPont™ Tedlar® Architectural Colored Film or a polyvinyl chloride (PVC) coating (specific weight 0.2-1.0 kg\m2) having at least two inflatable chambers 112 (FIGS. 3 and 10 ). The double-chamber construction provides a safe roof structure in the event that one of the inflatable chambers should fail. The roof material is also resistant to ultraviolet light to help reduce the effects of the sun on the temperature in the shelter. Theroof 108 and more specifically, theinflatable chambers 112 of the roof includepressure compensating units 132 to account for any air pressure changes during use, and one or more safety valves to prevent over inflation. The maximum pressure of each of the inflatable chambers is approximately three psi (0.2 bar), although the chambers can be made to accommodate other suitable pressures. - The
roof 108 is mainly used as a cover for the shelter and also acts as a system for water collection into one or more water storage bladder tank(s) 114 as described in more detail below. - One or more side wall panels or
side walls 110 and afront wall 111 are secured to at least one of the primary andsecondary support systems side walls 110 include buttons, zippers or other suitable attachment devices that allow the side walls to be easily secured to and removed from the primary and secondary support systems. One or more of theside walls 110 also include one or a plurality of adjustable zipped orbuttoned openings 134 so that shelters can be combined to form multiple units (i.e., a first-aid-shelter, a meeting area, or classrooms). - To provide comfortable conditions inside of the
shelters 100, especially in hot-humid climates, each of the shelters is equipped withadjustable ventilation panels 135 at the lower bottom of the rear inflatable roof section for cooler (denser, heavier) air supply, and at the upper front enclosure for exhaust of warmer (less dense, lighter) air. The concept of opposingair ventilation panels 136 provides for effective cross-ventilation, even when the shelter enclosures are closed. - Furthermore, vernacular structures, such as bamboo and wood, provide a great degree of cross-ventilation due to their loose wall and floor construction. The shelter can be opened with zipped and buttoned down panels at the lower back and full front of the shelter to allow for cross-ventilation. These apertures consist of a double-layer construction. The outer layer provides water-tightness and full enclosure during times of rain and the inner plastic screen allows for ventilation yet protects against insects.
- A floor or
underlying support surface 136 is placed on theprimary support system 118 and is made of a heavy duty PVC-coated, inflatable, flame retardant nylon that is supported by fiberglass floor rods. Bamboo, wood or other suitable materials may also be used to from the floor of the integrated shelter. - The integrated shelter kits/packages also includes accessories such as guy-lines with adjusters (not shown), suspension hooks (drips, etc.) (not shown), a rain
water collector system 104 including a rain water collector tank orbladder tank 114 with integratedcarbon filter purification 138, a ceramic filter cartridge 137 and a manual pump 140 (shown inFIG. 1 ) that is integrated into the support frame. - Each
integrated shelter 100 has a width of 3.30 meters, a length of 4.00 meters and a useful interior height of 2.75 meters. It is contemplated that theintegrated shelter 100 may be any suitable size or shape and is not limited to a specific width, length and interior height. - The sizing of the shelter kit/package including the tripartite tubular support structure and the inflatable roof and side walls is compliant with ISO container dimensions and payloads. Three shelter kits in line, each 4.00 meters in length, fit the most common standard international container with a length of 12.20 m, equal to two Twenty-Foot Equivalent Units (TEU), or 12.20 m×2.44 m×2.59 m.
- A single carrier includes sixty complete shelter kits fit into one container. The most effective mode of rapid deployment of a large number of integrated shelter kits is by helicopter such as an Erickson Sikorsky Skycrane Helicopter S-64. One flight carries one container with sixty complete shelter kits. Upon arrival at the site, the kits are unloaded. As shown in
FIG. 4 , the two front and rear support beams 124,126 are made of lightweight fiberglass and are assembled to the full shelter length of 4.00 meters. Thesecondary fiberglass rods 130 for the inflatable roof structure which are contained in the hollow support frames are assembled and the two upper and rear support frames are put together, and thewater storage tanks 114, the roofinflatable chambers 112,side walls 110,front wall 111 andPV panels 144 are installed in a last step. It should be appreciated that any method or series of steps may be used to assemble theshelter 100. - Other modes of transportation, such as train or flatbed truck, are also contemplated and are determined based on the availability of a particular mode of transportation and what type of transportation is permitted by the local infrastructure.
- When natural disasters or other disasters occur, fresh water is typically in short supply. Thus, each
integrated shelter 100 has an autonomouswater supply system 104 that is particularly needed in hot-humid climates. Rainwater is collected on the curved or sloped,inflatable roof 108, passed through a ceramic filter 137, and collected in at least one flexible, ultraviolet (UV) light inhibitedvinyl bladder tank 114. Theintegrated shelter 100 may also have a plurality ofbladder tanks 114. During periods of rain, thebladder tank 114, which is initially rolled up and stored underneath the platform of the integrated shelter, uncoils automatically due to the increasing water pressure from the water entering the tank. Thebladder tank 114 uncoils to a length of 0.60 meters (which is identical to the height of the raised dwelling platform) as it is filled with water. - As an example, the size of each shelter's
roof 108 is approximately (3.00 m [L]×4.00 m [W]) resulting in a collection surface having an area of 12 m2. The minimum rain fall in Southeast Asia in the months of January and February is 0.025 m3/m2 surface area=25 liters/m2×12 m2=300 liters/month. The maximum amount of rainfall in the months of September to November and March to April is approximately 2,500 liter/month. The average consumption per shelter unit (four occupants) is: 4×10 liters/day or 1,240 l/month. The size of the bladder tanks is coordinated with the size of the shelter support platform and its clearance from the ground. The shelter design is able to accommodate a maximum number of four (4) interconnected bladder tanks each having dimensions of 3.00 m (L)×0.35 (H)×1.00 (W) for a volume of 4.20 m3, or 4,200 liters. This tank size compensates for periods of insufficient precipitation during dry periods. - A first flush device, i.e., ceramic filter 137, ensures that runoff from the first spell of rain is flushed out and does not enter the system. This is necessary since the first spell of rain carries a relatively larger amount of pollutants from the air and the roof surface. The water is purified by activated
carbon cartridges 138 along with ultra membrane filtration or micro-membrane filtration modules incorporated in the bladder tank assembly. The purification components of thewater supply system 104 has the capacity to deal with E-coli and is designed to meet the World Health Organization's (WHO) water regulation standards. - Other methods of simple purification, such as adding chlorine tablets, can be used if warranted by local conditions. From the bladder tank, the stored water is pumped through flexible conduit, such as PVC tubing, to the inside of the shelter using a hand-operated or
manual pump 140 mounted on an internal sink. - During dry periods, the bladder tank(s) 114 recoil back under the
integrated shelter 100 using integrated stainless steel coils, and is also stored automatically beneath theplatform 106, which protects it against damage and soiling. Using thewater supply system 104 makes it is necessary to calculate the tank volume as a function of daily/monthly rain water availability at the site and the water consumption of four persons per shelter so that adequate water is available. An example calculation follows: -
1 shelter=4 person@110 liter/Person/Day consumption -
Shelter catch surface area: 3×4 m=12 m2 -
Assuming that the min. rainfall (such as in January/February)=0.025 m3/m2 surface=25 liter/m2×12 m2=300 liter/month -
4 persons×10 liter/day×31 days=1240 liter/month - Each
integrated shelter 100 also has anelectrical system 102 that generates and supplies electricity for lights, such as light emitting diodes (LEDs) 142 mounted in the shelters to illuminate the interior living space of the shelters, for small cooking equipment and for other electrical devices. Theelectrical system 102 includes an array of flexible, thin-film photovoltaic modules or cells (PVs) 144 with an efficiency of approximately η=12%, that generate electricity using solar radiation. Theshelters 100 each have a size of approximately 1429.39 mm×424.40 mm and are rated for a power of 32 watts and an operating voltage of 16.5 volts. At night the plastic photovoltaic film serves as the front enclosure of the shelter and provides privacy for the dwellers. The generation of electrical energy begins at the beginning of the day when the front shelter enclosure is opened to a vertical canopy and supported by fiberglass rods or local materials, such as bamboo sticks. - During the day-time the photovoltaic plastic sheets or
panels 144 also may serve as a cover against rain, and as a semi-private, intermediate space between two shelter modules facing each other (seeFIG. 9 ). In this space, school can be held, community meetings find a protected space and supplies for first aid shelters can be stored. - Because of the flexible patterns of the shelter layout (in semi-circles, circles etc.) shown in
FIG. 14 , the radiation exposure of the shelter walls to the cardinal directions of the sun causes the photovoltaic panels 144 to be only oriented as a horizontal roof surface facing the zenith. - To embed one or more of the thin-film
photovoltaic panels 144 in the canopy structure, the canopy structures are oriented independently of the orientation of the individual articulated shelters. - The maintenance-free clean energy of each
photovoltaic panel 144 is delivered as Direct Current power (DC). It is assumed that the dwellers in theshelter units 100 use electricity for cooking for a period of 2 hours/day. An electrical storage device orstorage battery 146, such as a car battery, of 13.5 kWh is therefore necessary, especially for overcast and night time conditions. - The following calculation determines the optimum number of square meter PV cells that are needed for a shelter at a given global radiation level:
-
- Since the lowest amount of global radiation amounts to 100 kWh/month/31 days=3.22 kWh/day or 3.220 Wh/day, battery storage is required for each shelter. Therefore, a minimum battery storage capacity of 2,700-3,000 Wh such as that of larger car batteries is recommended. Therefore, using electrical power over the course of five days results in 5×2,700 W=13,500 Wh or a PV net surface area (m2) of 13,500/2,700 W=5.1 m2 PV cells.
- The lighting for the
integrated shelters 100 is integrated into the fiberglass support tubing and consists of a series of shock and vibration resistant high-brightness lighting devices such as LEDs 142 that are each inserted into a UV resistant polycarbonate housing to eliminate dust and dirt buildup. It is assumed that a maximum power of 100 W/shelter unit×7 hrs/day=700 Wh/day will be needed for lighting. Thus, utilizing lighting with a small cooking station, or hot water boiler, of a maximum of 1,000 W×2 hrs/day=2,000 Wh/day. The resulting total power demand is 2,700 Wh/day for each integrated shelter. The monthly power use for each integrated shelter is 2,700 Wh/day×31 days=83.7 kWh/month. The lighting devices may be connected to thebattery 146 or to at least one of thephotovoltaic panels 144. - The above
integrated shelter 100 provides transportable, convenient, safe and durable temporary housing to people that are stranded and homeless due to natural disasters and other disasters. As a result, the devastating effects of such disasters on those people are lessened as they try to rebuild their lives. - While various embodiments of the present invention have been shown and described, it should be understood that other modifications, substitutions, and alternatives are apparent to one of ordinary skill in the art. Such modifications, substitutions, and alternatives can be made without departing from the spirit and scope of the invention, which should be determined from the appended claims.
- Various features of the invention are set forth in the appended claims.
