Description

Title Inventory management of items placed in container, which are further placed in an assembly unit

Field of Invention

[001] The invention relates to an inventory management system. More specifically, the invention relates to the inventory management system that is easy to handle and configured, and helps to locate the contents in a user-friendly fashion.

Background of Invention

[002] Today our kitchens have various containers comprising of multiple dimensions, shapes, models. These containers are stacked in shelves disoriented due to uneven sizes and shapes which causes ineffective usage of available space in kitchen.

[003] In furtherance, it is relevant to note that different kitchen items utilize different space, and they are required to be ordered or procured according to their space occupancy, rather than weight of the items, so that they can be placed easily within the containers meant for them.

[004] Other issues with the kitchen inventory are the items non-usage, and expiry period of the items. Users tend to forget availability of certain items in their inventory, which prohibits them to select a dish to be made considering non-availability of the ingredients. This sometimes leads to even re-procurement of the item, when the item is still available in the inventory. As items in kitchen inventory are generally perishable, long term non-usage, and further keeping the items in non- prescribed condition may lead to expiring of the items. Management of inventory to keep on checking, if something is unused for a longer period, or if something has expired, or perished, helps in effective management of the kitchen inventory. Such management of inventory is not possible for today’s urban class, who is currently engulfed in various other concerning requirements.

Object of Invention

[005] The object of the invention is to provide a mechanism for efficiently monitor, use, manage, and configure an inventory management system where various contents are managed. Summary of the Invention

[006] The object of the invention is achieved by the Inventory management system of claim 1.

[007] The Inventory management system includes one or more shelves, more than one container placed on the shelf, a memory unit, and a processing unit. The shelves have more than one location sensors placed at a predefined distance with respect to each other through out a length of the shelf. Each of the location sensor is configured with a location parameter, and senses a container identification of the container. The containers have a container identification configured to each of the containers. The container identification is sensed by the location sensor when the container is placed over the location sensor on the shelf. The containers are of more than one predefined size, such that wherein at least one of the geometrical dimensions of the container is around multiples of the predefined distance. The memory unit stores a mapping between the container identification and a content dentification identifying content placed in the container. The processing unit receives the container identification from the location sensor along with a location parameter, and fetches the mapping and match the container identification, and determines a content related information pertaining to placement of a content at a particular location. This embodiment is helpful as it automatically identifies regarding which content is placed at which location. Even if the location of the container changes, the system still identifies the new location of the container. In addition, the system provides a dynamic mechanism where user need not worry whether the container placed at any predefined place, and the user can place the content at any place, and the system shall keep a track of the container location. Also, the system provides flexibility to use any predefined size of the containers to be used for placement at any location onto the shelves. It is also pertinent to be that the container identification can be any parameter of the container also like color of the container. In such scenario each container shall have a unique color so that the location sensor can sense identification of the container appropriately.

[008] According to one embodiment of the inventory management system, wherein the location sensor is a location reader, and the container has a location tag affixed, wherein the location tag has electronically readable code readable by the location reader. The location reader reads the electronically readable code. The memory unit store the mapping between the electronically readable code and the content identification. The processing unit receives the electronically readable code along with the location parameter, and matches the mapping with the electronically readable code and determines the content related information pertaining to placement of the content at the particular location.

[009] According to another embodiment of the inventory management system, the system includes a input unit which receives a configuration input for configuring the content identification with the container identification or the electronically readable code. The processing unit receives and processes the configuration input, and generates the mapping between the content identification, and the container identification or the electronically readable code. This embodiment helps to configure specific contents to particular containers.

[010] According to yet another embodiment of the inventory management system, wherein the container identification or the electronically readable code further includes at least a container size information related to size of the container, or a content state for which the container is fit for, or combination thereof.

[Oil] According to one embodiment of the inventory management system, wherein the content identification further includes at least a state of the content or a density of the content, or combination thereof.

[012] According to another embodiment of the inventory management system, wherein the input unit receives an amendment input to delete or change content identification linked to the container identification. The processing unit receives the amendment input, and fetches the mapping, and process the mapping and the amendment input to update the mapping. This helps in further amend any previous configurations made to the container and the contents placed into those containers.

[013] According to yet another embodiment of the inventory management system, wherein the shelves are either placed side by side, or one above the other, or combination thereof. This helps to build up the inventory management system flexibly according to the spatial possibilities in which the system or the assembly unit built up by the shelves are to be placed. [014] According to one embodiment of the inventory management system, wherein the location tag is affixed to a first predefined location onto the container, and the location reader is placed on the shelf is such a way that the location reader shall be in proximity to the predefined location of the container when the container is placed on the shelf. This arrangement of the location tag placement onto the container and the location reader shall provide an efficient reading of the identification tag. It is pertinent to be noted that the dimension of the shelf, placement of the location readers on the shelf, dimensions of the box, and first predefined location on the container where the location tag is affixed are correlated, so that the used need not worry that while placing the container the location tag may or may not be aligned to the location reader. Rather, because of appropriate dimensions of container and shelf, and appropriate locations of reader and tag helps in placement of the container, such that the location tag should be aligned to the location reader. In fact, when the shelf is full with containers, that there is no space for placement of containers, the location tags of the containers shall be at least aligned to at least one for the location reader of the shelf.

[015] According to yet another embodiment of the inventory management system, wherein at least one of the containers and the shelf are provided with a magnetic material, such that when the container is in proximity to the shelf, a magnetic coupling is established between the container and the shelf. This further helps in easy placement of the container, and shall also help in appropriate placement of the container onto an appropriate location onto the shelf, so that location tag shall be readably aligned to one of the location readers. It is possible to provide the magnetic arrangement in proximity to location reader or the location tag, or both, so that the readable alignment is perfect or almost perfect between the location reader and the location tag.

[016] According to yet another embodiment of the inventory management system, wherein the container is provided with at least one of a handle fixing provision or a lid fixing provision, or combination thereof, such that a handle is adapted to be replaceable fixed to the handle fixing provision, or a lid is adapted to be replaceable fixed to the lid fixing provision.

[017] According to one embodiment of the inventory management system, the system includes one or more weight sensors configured to each of the shelves. The wight sensors measures a weight related to one or more containers on the shelf, and generates a sensor weight data. The processing unit receives and processes the container identification or the electronically readable code, the sensor weight data and the mapping, and determines a quantity or a change in quantity of content in one or more of the containers. The quantity relates to at least weight of the content, volume of the content, density of the content or combination thereof. This embodiment helps in determining quantity along with location of the content at any given point of time.

[024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention belongs. The system, methods, and examples provided herein are only illustrative and not intended to be limiting.

[025] Embodiments of the present invention will be described below in detail with reference to the accompanying figures.

[026] FIG 1 shows a representation of a shelf 2 which has containers 8 placed onto it. The shelf 2 has identification readers 3 placed at predefined distance 4 with respect to each other. These identification readers 3 are placed in such a pattern, having a predefined distance between each other throughout the length 5 of the shelf 3. While, the containers 8 has a dimension 9 which is related to the predefined distance 4, such that the dimension 9 shall be around absolute multiples of the predefined distance. In the current embodiment, width 9 of the containers 8 is shown to be absolute multiples of the predefined distance. As shown in the figure, there are two containers 8 as shown to be placed onto the shelf 2 having two different widths 9a, and 9b, where the width 9a is equal to the predefined distance 4, and the width 9b is twice the predefined distance 4. Similarly, there can be other containers 8 which can be placed onto the shelf 2, which has width in absolute multiples of the predefined distance 4. Here the absolute multiples can be 1, 2, 3, 4, and so on. It is pertinent to be noted that the predefined distance 4 or the dimensions of the container need not be absolute numbers. In an alternate embodiment, instead of width, any other dimensions 9 such as height, diameter, etc., can have such relationship with the predefined distance 4 to be in absolute multiples of the predefined distance 4. In furtherance each of the containers 8 has a location tag 15 affixed at predefined location 21 of the container 8. This predefined location 21 is such that when the container 8 is placed onto the shelf 2, identification tag 15 comes in readable range of the location reader 3. The identification tag 15 has a electronically readable code which can be read by the location reader 3. This predefined distance 4 shall have correlation to the dimension 9 of the container which is in relation with the predefined distance 9 between the readers. This correlation between the predefined distance 21 of the affixation of the identification tag 15 onto the container 8, dimension 9 of the container 8, and the predefined distance 4 are so correlated that an user of the system can easily place the container 8 on the shelf without much worrying whether the identification tag 15 shall be in readable range of any of the location reader 3 affixed to the shelf 5. Due to this correlation, generally when a user shall pick up a container 8, and when he has to replace it back, than the gap between the two container shall be of such dimension, that when the user place the container 8, it shall automatically get placed so as to make the identification tag 15 into be readable range of an appropriate location reader 3. In case two container 8 are replaced side by side, than similarly when a person place the container closely with respect to already placed container on the shelf 2, the container 8 shall get placed appropriately to make location tag 15 readable by an appropriate location reader 3. Similarly, any kind of such replacements and placing back of the containers 8 shall have ease of placements back of the container 8 to make the inventory management system workable. In addition, the shelf 2 has also weight sensors 22 placed at extreme ends of the shelf which measures the weight of the shelf. It is pertinent to be noted that the presence of weight sensors 22 are helpful specifically in scenarios when the user just not need to locate the content or container holding the content, but also the quantity of the content inside the container. In case, where such quantity tracking is not required, the weight sensors is not required. Also, it is pertinent to be noted that the first location reader 3 can be placed near to one of the extreme ends of the shelf 2, however the placement of the identification reader 3 shall be in correlation to the predefined location 21 of the affixation of the identification tag onto the container, so that when the container 8 is placed on the extreme end, it should clearly establish readable range of the identification tag 15. In furtherance, there can be multiple such shelves which create an assembly unit, which shall be part of the entire inventory management system. Such assembly unit is described in FIG 2, and one of the preferred embodiments of the inventory management system is described in FIG 3.

[027] FIG 2 discloses a assembly unit formed by multiple shelves which are stacked one over another each other and side by side. The exemplary assembly unit which is shown in figure, shows six rows of shelves and two columns of shelves to form the assembly unit. The figure shows three dimensions 9a, 9b, 9c of container placed on each of the shelves. The container with dimension 9b is twice the size of container of dimension 9a, and the container with dimension 9c is twice the size of container of dimension 9b. The dimensions are made in such a way that the boxes are fittingly placed to each other, and with respect to the shelf. Such close fit arrangement helps in eacy placement of the containers by the user, as user will not have to worry whether he has placed the container appropriately, so that the location tag of the container shall be in readable range of location reader of the shelf. In an embodiment, a marking on the container may be provided, which shall clarify the user of the inventory management system to place the container in appropriate orientation, so that further help to support in efficient placement and remove any doubt regarding how the placement of the container is to be made, so that the location tag shall be in readable range of the location reader.

[029] FIG 3 shows a schematic illustration of an exemplary embodiment of the inventory management system 1. For ease of illustration, and better readability an example is shown with only on shelf 2 with two containers 8, however there can be more containers 8 placed on one shelf 2, and there can be more than one shelves 2 which can be part of the inventory management system 1, which can be placed on one above another, and which can be placed side by side, in a similar way, as shown in FIG 2.

[030] The inventory management system 2 location tags 15, location reader 3, weight sensors 22, processing unit 13, memory unit 10, and input unit 16 which cooperates together to a content related information 14 pertaining to placement of a content at a particular location, and also quantity 18 or a change 19 in quantity of content in one or more of the containers.

[031] The location reader 3 are placed at a predefined distance with respect to each other through out a length of the shelf. Each of the location reader 3 is configured with a location parameter 6, and senses an electronically readable code 7 of a container 8. The location parameter 6 shall be information about location of the shelf at which the container is placed. In scenario when there is more than one shelf, and they are stacked in rows and columns as shown in FIG 2, the location parameter shall also have information about the row and column in which the location reader 3 is placed. Also, it is pertinent to be noted that instead of identification tag 15, unique characteristics of the container 8 such as color of the container, or unique characters of the contents placed inside the container 8 can be used as container identification which can be sensed by a location sensor, such as infrared sensors, or camera.

[032] The container 8 has location tag 15 affixed to a predefined location of the container. The location tag 15 shall have electronically readable code written or embedded into the location tag 15 which can be read by the location reader 15. Even though, in the figure, the container 8 of similar sizes are show, the container 8 can be of different sizes. However, the predefined sizes shall be based on predefined distance between the location reader. One of the geometrical dimensions of the container 8 is around multiples of the predefined distance 4.

[033] The memory unit 10 stores a mapping 11 between the container identification 7 and a content dentification 12 identifying content placed in the container 8. The processing unit 13 receives the container identification 7 from the location sensor 3 along with the location parameter 6, and fetches the mapping 11 and match the container identification 7 with the mapping 7, and determines a content related information 14 pertaining to placement of a content at a particular location. The content related information 14 shall clearly determine which content is located at which location. Additionally, for easier identification one of the property of the container can also be mentioned, such as color of the container, or type of the container, like jug with handle, or container with pouring spout, or a container with side lid, etc.

[034] It is pertinent to be noted the location tag can be a bar code, RFID tag, or any such tags which has electronically readable code embedded or written on them. While, the location reader 3 shall be specific kind of reader which can read specific kind of electronically readable code 7 from a specific kind of location tag 15, such as RFID reader for RFID tag, Barcode reader from barcode, etc.

[035] The weight sensors 22 are placed at extreme ends of the shelf. Each of the ends should have the weight sensors 22 in symmetry to have proper weight management. In this embodiment two sensors 22 are show, however, there can be four weight sensors to be provided for a planar shelf 2, one for each corner of the shelf, which means two sensors for each of the edges. The weight sensors 22 measures a weight related to one or more containers 8 on the shelf 3, and generates a sensor weight data 23. The processing unit 13 received the sensor weight data 23 along with the electronically readable code 7, and further processes them along with the mapping 11, and determines a quantity 18 or a change 19 in quantity of content in one or more of the containers 8. The quantity relates to at least weight of the content, volume of the content, density of the content or combination thereof. The quantity 18 or a change 19 in quantity of content along with location of the content shall give a wholistic picture of the inventory. However, in alternate embodiment, where quantity measurement is not required, and only pertinent information for management of inventor is identification of the location of the inventory where it is placed, the weight sensors 22 are not required.

[036] The weight sensors keep a track of a weight of the shelf, which includes weight of the self itself, the weight of the containers, and the weight of the items in the container. It is to be noted that the shelf weight shall remain constant through out, however the weight change shall be due to the container itself, or due to change of weight of items inside the container. Every time an activity such as pick up of the container, placement of the container, using out items from the container, the load cells provide a weight of the containers, and shelf.

[037] Another salient feature of the system is configuration and amendment to the configuration for the content to the container. Whenever a content is first required to be introduced to the inventory, the system needs to know regarding which container shall be holding the content. Whenever, a user shall like to change the container or remove a content from the inventory, he needs to amend the configuration information which is already stored in memory unit 10 of the system 1.

[038] For configuring a content to a container, the input unit 16 shall receive a configuration input 17 for configuring the content identification 12 with the electronically readable code 7. Further the configuration input 17 is sent to the processing unit 13. The processing unit 13 receives and processes the configuration input 17, and generates the mapping 11 between the content identification 12, and the electronically readable code 7. [039] For amending the configuration, the input unit 16 receives an amendment input 20 to delete or change content identification 12 linked to the container identification 7, and sends the amendment input 17 to the processing unit 13. The processing unit 13 receives the amendment input 20, and fetches the mapping 11 , and processes the mapping 11 and the amendment input 20 to update the mapping 11.

[040] It is pertinent to be noted, that in one embodiment, the electronically readable code 7 further includes at least a container size information related to size of the container, or a content state for which the container 8 is fit for, or combination thereof.

[041] In another embodiment, the content identification 12 further includes at least a state of the content or a density of the content, or combination thereof.

[042] As the whole system is modular in nature, the shelves 2 can mechanically be removed from the assembly unit easily or replaced into the container in a user-friendly manner. It is to be noted that each of the shelf 2 shall be provided with the means to communicatively couple the hardware of the shelf 3 with the processing unit 13. Such communication coupling can be done through a wireless communication module provided along with the shelf, or through a wired communication coupling which shall be having a connector to communication wiring of the assembly unit. The location reader 3 and load cells 22 are connected to the communication module, so the user need not worry about hardware elements of the shelf for individually coupling them to the processing unit. This provides a plug-play experience to the user.

[043] The containers 8 have a standard volumetric capacity provided. Hence, each container can only hold a particular volume of a content. It is to be noted that each content may differ in their density and hence weight items can differ to occupy the space in containers. While configuring a container 8, with respect to a content, a maximum weight of a content which can be held by the container 8 is predefined based on density of the contents. It is to be noted that density of content can differ due to its state, for example red pepper can be whole dry pepper, pepper flakes, and powdered pepper. All three shall have different density, and one container can hold different weight of each of them. Hence, while user is configuring the container with a content, the user shall provide input not just with respect to the content, but also with respect to a state of the content. On receiving input for the state of the content, the processing unit configures the electronically readable code 7 with content identification, and content’s state. Further, the processing unit can identify the density based on the information provided, and configures the density of the item.

[044] Density information is helpful for handling futuristic error. For example, let’s consider the user has emptied all the preconfigured containers for washing. After washing, the user mistakenly put across non-configured items in the containers with different electronically readable codes 7. As soon such filled containers are kept onto the shelf 2, even though location readers reads correct location tag, but the weight sensors captures weight information, which on processing identifies a density of the item to be different from preconfigured density, and notifies the error to the user through either a display provided with the assembly unit, or a mobile device, which is communicatively coupled to the processing unit.

[045] In one embodiment, another input related to expiry of the item is received by the processing unit at the time of procurement of the item, or at the time of the placement of the item in the container. This input can be directly provided by a third-party vendor server from whom the items are procured, or can be entered by the user when they are placing the item into the container. The processing unit keeps a track of quantity of the item according to the expiry period. A user can configure a threshold expiry time period regarding, when they shall like to be notified for expiry of the product. Such date can be less than or equal to the date of expiry of the item. The processing unit keeps a track of the time period based on inputs received from the internal clock, and if there is a quantity left in the container, the processing unit notifies the user regarding the item to be expired, or already expired. The processing unit can also notify regarding time period left for expiry of the product. If preconfigured, the processing unit can keep on notifying the user for the expiry of the product at regular interval, if the quantity still identified to be remaining into the container. The processing unit can further be configured to even let know the quantity left in the container to be used before the expiry date, List of reference signs
