DETAILED DESCRIPTION
Example embodiments relate to apparatus and methods that store and move objects in a kitchen tray assembly that includes a plurality of shafts for storing and moving the trays and the objects.
Kitchens are often constructed with a limited amount of storage space for food, appliances, and other items. Further, this storage space can be located in an inconvenient place, such as being too high to reach without standing on a stool or chair. Example embodiments solve these problems and other problems and provide a kitchen tray assembly or kitchen storage system that efficiently stores items in a kitchen or other storage location.
Another problem is that a user may not know where items are stored in a kitchen and may have to open drawers or cupboards while searching for the item. Example embodiments solve these problems since the kitchen tray assembly or kitchen storage system tracks locations of objects and provides this information to users, such as displaying this information to users while the users are located in the kitchen. This information can also be provided to and displayed on remote electronic devices, such as smartphones and other computers.
One example embodiment includes a motor that moves the trays within a T-shaped shaft, and a controller that connects with the motor to control movement of the trays within the shaft.
In one example embodiment, the T-shaped shaft includes a first horizontal compartment that is connected or adjacent to a ceiling of the kitchen, a second horizontal compartment that is connected or adjacent to the ceiling and aligned with the first horizontal compartment, and a vertical compartment that is connected or adjacent to a wall of the kitchen and connected to the first and second horizontal compartments to form the T-shaped shaft.
The first and second horizontal compartments include a plurality of trays that store and move objects located thereon and also include a plurality of empty spaces or tray receiving spaces that are sized and shaped to receive an empty tray or a tray with objects. The trays move through the shafts and into the tray receiving spaces so a user can selectively retrieve a desired tray. In one example embodiment, a number of tray receiving space is one less than a number of the trays in the kitchen tray assembly.
In an example embodiment, the first and second horizontal compartments include a track that forms a loop around which the objects in the kitchen move while in the T-shaped shaft. For example, the track can include runners, rails, grooves, or other pathways for moving the trays throughout the compartments. By way of example, the trays include or rest on one or more wheels or bearings that roll or glide along the tracks.
A user can control the trays with a control pad or a user interface. For example, a control pad or control display is located near or with the kitchen tray assembly. Further, the user can remotely control the trays. For example, the system includes a wireless receiver that receives commands from a handheld portable electronic device or HPED (such as a smartphone) and communicates the commands to the controller in order to remotely move the trays within the shafts.
An example embodiment also tracks and stores a location of trays and which objects are located on which trays. This storage information can be displayed on a user interface of the control pad and/or transmitted to a HPED for display. For instance, the user interface on the HPED provides a map or other visual indication of where the trays are located in the shafts and which objects are located on which trays.
FIG. 1A shows a structure or building 100 that includes a kitchen 102 in which a kitchen storage system 104 is installed in the kitchen 102.
FIG. 1B shows an electronic system 105 that includes the kitchen storage system 104 that communicates with a handheld portable electronic device (HPED) 116 via one or more a network(s) 114. In this example embodiment, the kitchen storage system 104 includes trays 106 on which objects can be stored, a motor 108 that moves the trays 106 within the kitchen storage system 104, a controller 110, a transmitter/receiver 112, a control pad and/or user interface 118, and a memory 120. The controller 110 communicates with the motor 108 and the transmitter/receiver 112 to control movement of the trays 106 within the kitchen storage system 104. The controller 110 also communicates with the control pad and/or user interface 118 and the memory 120.
The transmitter/receiver 112 wirelessly receives commands from the HPED 116 that move the trays 106 within the kitchen storage system 104. In one example embodiment, the transmitter/receiver 112 wirelessly transmits information on location of the trays 106 in the kitchen storage system 104 to the HPED 116. In an example embodiment, the transmitter/receiver 112 communicates the commands to the controller 110 in order to remotely move the trays 106 within the kitchen storage system 104.
The control pad and/or user interface 118 enables a user to communicate with the kitchen storage system 104, such as selecting any object stored on the tray 106 to retrieve or obtaining information of any objects or tray stored in the tray 106. The memory 120 stores an identity of the objects that are stored on the trays 106. In one example embodiment, the memory 120 stores which of the objects are stored on which of the trays 106. In an example embodiment, the memory 120 stores the identification of the objects and an identifier that corresponds to a tray on which an object is located, and records tray movement history.
The HPED 116 (such as a smartphone, a tablet computer, a laptop, or other computer) can include a memory 122, a display 124, a kitchen storage manager 126, a transmitter/receiver 128, and a processor 130. The memory 122 stores the information transmitted from the kitchen storage system 104.
The display 124 displays information, such as the information of the objects and the identifier. The kitchen storage manager 126 (such as a software application) enables the user to communicate with the kitchen storage system 104, such as making commands to retrieve a particular object(s) stored on the trays 106, and retrieving information of the objects stored on the trays 106. The transmitter/receiver 128 wirelessly transmits commands from the HPED to the kitchen storage system 104, and receives information stored in the kitchen storage system 104.
FIG. 2 shows a kitchen tray assembly (or a kitchen storage system) 200 in accordance with an example embodiment. The kitchen tray assembly 200 is installed in a kitchen 201 and stores and moves objects in the kitchen 201. The kitchen tray assembly 200 includes a rectangular shaped horizontal shaft 202 located adjacent and connected to a ceiling 208 in the kitchen 201, and an elongated vertical shaft 204 that connects to a wall of the kitchen 201 and to the horizontal shaft 202. The horizontal shaft 202 and the vertical shaft 204 form a T-shaped shaft 206, in which objects can travel through the T-shaped shaft 206.
The horizontal shaft 202 has a size that holds a number of trays (N) and includes a number of empty tray receiving space 203 (M), in a way that M is equal to N minus one and N is greater than one. By way of example, FIG. 2 shows two trays and one tray receiving space.
Objects can be stored on trays and transported through the kitchen tray assembly. As an example embodiment, a toaster 210 and a coffee maker 212 are stored on a tray 220, whereas a kettle 214 and a blender 216 are stored on a tray 218.
As an example embodiment, the trays include rollers or wheels 222 that roll along a path or track 224 that is formed along the horizontal shaft 202. As such, the trays can move within the T-shaped shaft 206 and along both the horizontal shaft 202. In one example embodiment, the track 224 forms a loop around which or through which the objects in the kitchen move while within the T-shaped shaft 206. The movement of the trays are powered by a motor 226.
The trays can be raised and lowered within the vertical shaft 204 through a lifting system such as a pulley assembly 228 as shown or another system, such as a periscope-type lifting system, motor and cable system, conveyor belt system, moving sidewalks, escalators, or other transport system.
As illustrated in FIG. 2, the tray 220 is lowered to a countertop 234 by the pulley assembly 228 so that the toaster 210 and the coffee maker 212 are placed in an opening in the vertical shaft 236 and accessible to a user. When a tray is not in use, it can be raised and stored in the horizontal shaft that is located above cupboards 250.
As an example embodiment, a sensor/reader 230 is installed on the tray 218 and senses an identification of the objects (i.e. the kettle 214 and the blender 216) stored on the tray 218. Another sensor/reader 231 is installed on the tray 220 to identify the toaster 210 and the coffee maker 212.
The sensor/reader detects and identifies the tray and objects on the tray using, by way of example, object recognition or object identification. For example, each tray and/or object on the tray has a unique identification or unique identifier that can be read by the sensor/reader. Examples of unique identifiers include, but are not limited to, a data tag or other tag that includes a unique tag value, a radio frequency identification (RFID), chip with encoded information, barcode, a near field communication (NFC) tag or device, readable magnetic strip, proximity card or device, contactless smart card or device, bokode, QR code, or other unique mechanical and/or electrical identifier.
The kitchen tray assembly 200 further includes a controller 232 that connects with the motor 226 and controls movement of the trays within the T-shaped shaft 206.
As another example embodiment, the horizontal shaft includes a first horizontal compartment 240 that is connected to the ceiling 208, and a second horizontal compartment 242 that is connected to the ceiling 208 and aligned with the first horizontal compartment 240. The vertical shaft includes a vertical compartment that is connected to the wall of the kitchen, and to the first horizontal compartment 240 and the second horizontal compartment 242. The first horizontal compartment 240 and the second horizontal compartment 242 have a rectangular shape and hold a number of empty tray receiving space 203, in which a number of the empty tray receiving space 203 is one less than a number of the trays in the kitchen tray assembly.
