Description
BACKGROUND
1. Field of the Invention
[0001] The present invention relates generally to window blind
systems, and more specifically, to a system and method for remotely
controlling window blinds.
2. Description of Related Art
[0002] Window blinds are used in homes to control inlet of sunlight
to homes. A conventional window blind system includes a headrail
that is fixed at top of the window. Further, the window blind
system includes a blind assembly suspended from the head rail. The
angle of the blinds can be controlled by application of an external
force in order to tilt the window blinds that changes the amount of
sunlight entering the home through the window.
[0003] Various types of mechanisms are available to lift or change
the tilt angle of the window blinds. Some window blind systems may
have a visible lift cord and tilt cord to change the tilt angles of
the window blinds. One disadvantage of these systems is that since
the lift cord and tilt cords are visible, it is accessible to
children and can be pulled or stretched by them, while playing that
may cause an accident.
[0004] Further disadvantages include insecurity, for example
thieves can monitor window blind movement to gage if someone is
home or away on vacation. With an automated solution you can
schedule your blinds to open and close when you are away.
[0005] Yet another disadvantage includes energy inefficiency, for
example heat comes in during the summer and/or blocked during the
winter. With an automated solution you can choose to let the light
in or control how your blinds provide insulation.
[0006] There are other window blinds systems where the tilt cord or
lift cords are hidden and are not easily accessible or are
concealed. In some window blind systems having concealed cords,
there is provided a spring means to keep the blinds in balance and
to hold the blinds and bottom rail in position after an adjustment
of the blinds. There are other window blind systems known in the
market, with concealed cords, which uses a tension force of a
positioning cord in order support the bottom rail in position after
an adjustment of the window blinds. However, the use of spring is
always prone to elastic fatigue. After some time of usage, when the
elastic fatigue kicks in, the spring mechanism or the positioning
cord system cannot support the bottom rail accurately in position.
Also, majority of these designs are used for controlling the
elevation of the blinds only. For controlling the tilt angle of the
blinds, additional tilting rod and mechanism must be added to the
already complex window blind system. Since, the lifting and tilting
angle of the blinds is separately controlled.
[0007] Unfortunately, when it comes to controlling horizontal
blinds no product is on the market that directly operates with
existing home automation systems using a wireless mesh network
protocol to conveniently and easy control the tilting of blinds.
Accordingly, the present invention provides for a system and method
with the ability to integrate into home automation wireless mesh
protocols for the control of window blinds conveniently.

defined by the appended claims.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0024] Illustrative embodiments of the system and method of use of
the present application are provided below. It will of course be
appreciated that in the development of any actual embodiment,
numerous implementation-specific decisions will be made to achieve
the developer's specific goals, such as compliance with
system-related and business-related constraints, which will vary
from one implementation to another. Moreover, it will be
appreciated that such a development effort might be complex and
time-consuming, but would nevertheless be a routine undertaking for
those of ordinary skill in the art having the benefit of this
disclosure.
[0025] The system and method of use in accordance with the present
application overcomes one or more of the above-discussed problems
commonly associated with conventional blind control systems.
Specifically, the present invention provides for a blind tilt
control device as a part of a home automation system that can be
controlled via an interface, or automatically based on commands
received from other networked devices within the home automation
system. These and other unique features of the system and method of
use are discussed below and illustrated in the accompanying
drawings.
[0026] The system and method of use will be understood, both as to
its structure and operation, from the accompanying drawings, taken
in conjunction with the accompanying description. Several
embodiments of the system are presented herein. It should be
understood that various components, parts, and features of the
different embodiments may be combined together and/or interchanged
with one another, all of which are within the scope of the present
application, even though not all variations and particular
embodiments are shown in the drawings. It should also be understood
that the mixing and matching of features, elements, and/or
functions between various embodiments is expressly contemplated
herein so that one of ordinary skill in the art would appreciate
from this disclosure that the features, elements, and/or functions
of one embodiment may be incorporated into another embodiment as
appropriate, unless described otherwise.
[0027] The preferred embodiment herein described is not intended to
be exhaustive or to limit the invention to the precise form
disclosed. It is chosen and described to explain the principles of
the invention and its application and practical use to enable
others skilled in the art to follow its teachings.
[0028] Referring now to the drawings wherein like reference
characters identify corresponding or similar elements throughout
the several views, FIG. 1 depicts a simplified diagram of a home
automation mesh network system 101 in accordance with a preferred
embodiment of the present application. It will be appreciated that
system 103 overcomes one of more of the above-listed problems
commonly associated with conventional window blind control
systems.
[0029] In the contemplated embodiment, system 101 includes a window
blind control device 103 configured to engage with a tilt rod of
conventional window blinds, and thereby tilt window blind slats to
open and closed positions of the window blinds 107 via a control
system 105. The control system can vary in components, some
embodiments including a PCB, the control system having a
communication board configured with a home wireless network mesh
protocol configured to provide a means to incorporate the device
103 into a home network. The system further includes the home
automation mesh network, which includes a plurality of networked
devices 108, 109, 110, 111 and/or a home automation controller, all
being able to communicate with each other, as well as a computing
device 115 with an interface 113.
[0030] It should be appreciated that the various devices 103, 108,
109, 110, 111 can receive commands based on the user's desires
through interface 113 or through other means, such as a home
automation controller 106. For example, one device may be a home
thermostat that the user can control remotely. In addition, it
should be appreciated that control system 105 is configured to be
commanded based on one or more sensors, such as a temperature or
light sensor, incorporated into the networked devices or device
103, wherein the control device will alter the blinds tilt position
based on a predetermined criteria, such as a temperature, or a
light level. Examples of home automation controllers 106 include
devices, such as, but not limited to, Wink Hub, Smart Things Hub,
and so forth. Further, each of the networked devices has an
associated unique identifier. Examples of the wireless mesh network
protocol may include, but are not limited to, Bluetooth MESH, Radio
Frequency (RF) control, Z-Wave, ZigBee, FabFi, SolarMesh, WING,
Wireless Backhaul (WiBACK) and so forth. It is contemplated that an
Amazon Alexa.RTM. can be configured as the computing device 115
with interface 113 to provide a means of commands.
[0031] One of the main advantages of such a network is that the
devices to be controlled need not be placed near each other, the
home automation controller 106 or the computing device 115. The
device to be controlled can be accessed by relaying control signals
from other network devices connected to the same home automation
controller.
[0032] Further, the device 103 can be configured to operate in one
or more modes such as, a primary mode (automated) and a secondary
mode (manual). In the automated mode of operation of the device 103
can be controlled by the computing device 115 communicating with
the home automation controller, wherein the user merely inputs a
command through the interface.
[0033] A second automated mode involves association between the
control device 103 and one or more of the other networked devices.
An example includes the control of device 103 based on change in
temperature in the environment surrounding the device 103 or the
window blinds 107. In yet another mode of operation, the device 103
may control the opening and closing of the window blinds 107 based
on a position of the mesh networked devices 109 or computing
devices 115 such as a mobile phone of the user, a smart watch, a
laptop, and so forth. For example, the network sensors interfacing
the device 103 may sense when the networked device approaches the
device 103 or is within a predefined area nearby, and the opening
and closing of the window blinds may be controlled accordingly. The
control system may also control the window blinds at a site using a
proximity detection of a mobile device or the networked device,
which may be based upon the detection of a number of zones. Each of
the zones may be associated, with a predefined temperature
threshold of a thermostat or the control system included in that
device or other energy consuming device.
[0034] Further, the temperature threshold corresponding to a zone
may be different from the temperature thresholds corresponding with
each of the other zones. A database of the interface may store
multiple values such as, a position threshold, a plurality of
temperature thresholds, a plurality of times, a plurality of voice
commands. The device may be configured to receive the voice
commands from the computing device interface and process them based
on comparison of prestored voice commands for controlling the
opening and closing of the window blinds.
[0035] In another mode of example, the device may control the
window blinds based on a sunrise a sunset schedule. This mode of
operation can be coupled by providing interfacing of the device
with a plurality of network connected photo-sensors as the one or
more networked devices. The photo-sensors sense the absence or
presence of sunlight using the photoelectric receiver.
[0036] A third automated mode includes use of the interface and the
computing device to send a command to the control device. This
could include the user setting a time through the computing device
which commands the control device to open or close the blinds.
[0037] The secondary operational mode allows the device 103 to be
operated in manual mode using a manual rotary switch that will be
discussed later in detail. In this embodiment of the invention,
there may be an input device connected to the device 103 like a
remote control or a manual rotary switch. Through this remote
control or the manual rotary switch, a user can control the device
103 for tilting of the window blinds.
[0038] Now, referring to FIG. 2 control device 103 for controlling
tilt angle of window blinds is shown. Device 103 is configured to
be fitted into any existing horizontal window blind system. Also,
the device 103 is so configured that it can work with an existing
home automation controller installed within a home. The device 103
includes a housing 202 that encloses various parts of the device
103. The housing 202 may be made up of anyone of a plastic, a
metal, or a fiber.
[0039] The housing 202 may further include a top lid (shown in FIG.
4) that may be opened to access internal parts of the device 103.
The device 103, further includes a tilt rod receiving opening 210
into a shaft 226 that extends through a length of the housing. As
discussed later herein, the shaft 226 includes variously sized, and
shaped openings 210 which can thereby allow for use with one or
more sizes, shapes, and the like of window blind tilt rod adapters.
Further, the shaft can include a set screw 228 to secure the shaft
to the tilt rod passing through.
[0040] The device can include a port 214 for receiving a USB
charger or the like. In the preferred embodiment, the device 103
can be powered in one of three ways, including direct 5V powered
supplied from USB adapter; a rechargeable battery and USB charger;
and a rechargeable battery and a solar panel. The device 103 can
further include an auxiliary power ports 216 for solar panel
connection.
[0041] The device 103 includes a motor 224 with a motor fixing unit
222. In an embodiment of the invention, the motor 224 is a Direct
Current (DC) motor with a hall effect sensor 229 and a 6 pole
magnet 231. Examples of the DC motor may include, but are not
limited to, a DC brush motor, a stepper motor, etc. The motor 224
is placed inside the device 103 using the motor fixing unit
222.
[0042] Further, the motor engages with a gear system 220 to rotate
the shaft. The hollow drive shaft 226 is placed in a manner
wherein, the hollow drive shaft 226 passes through the housing and
engages with tilt rod. The PCB/Control system 227 shall include a
transeiving unit (not shown in figure) that helps the device 103 to
communicate with other devices like existing wireless home
controller through wireless communication. The communication can be
through a home automation wireless mesh protocol wherein the
protocol is chosen from a group comprising a ZigBee protocol,
Bluetooth MESH, Thread., FabFi, Solar mesh, WING, Wireless
Backhaul, and a Z-wave protocol.
[0043] The disclosed invention may be implemented using any other
suitable existing mesh network standard Examples of the wireless
mesh network protocol may include, but are not limited to,
Bluetooth MESH, Radio Frequency (RF) control, Z-Wave, ZigBee,
Thread, FabFi, Solar Mesh, WING, Wireless Backhaul (WiBACK) and so
forth. The motorized device for control of horizontal window blinds
tilt position is not limited to the specific methods described by
the Z-Wave standard. The invention can be adapted or scaled to use
other home automation mesh network profile standards such as, but
not limited to, those defined by Z-wave. In addition, it is
contemplated that the communication board can be removable and
replaceable. This will allow users the ability to continue to use
the device and just swap out the communication board.
[0044] The control system of the device is configured to store data
and settings, the data including at least a unique identifier
associated with the device.
[0045] In FIG. 3, a simplified diagram depicts a window control
system 301, having the control device 103 positioned within a
headrail 302 and engaged with a tilt rod 303 via an hollow drive
shaft 304. The device 103 is configured to receive power from a
power source 305. It should be appreciated that a pass through
adapter 307 can be positioned to communicate with an exterior of
the headrail 302. The adapter 307 can have a button/switch 311 and
a charging port 309, as shown in the detailed view. The
button/switch 311 in one embodiment is a single button, that is
configured to communicate with the control system and can provide
commands based on the number of times pressed. This provides for a
simple means for a user to send commands, such as a calibration
command, to device 103. Further, the button/switch 311 can be
rotary switch, which can provide for manual operation of the device
103.
[0046] Device 103 can function with a plurality of power options.

In some embodiments, the motor is a dual shaft motor with an
attached magnetic encoder. In the preferred embodiment, the
magnetic encoder includes a Hall effect sensor; and a 6 pole
magnetic disc. In some embodiments, the motor is mounted with a
mount motor fixing unit 1013, the fixing unit having a channel and
containing a vibration absorbing material to reduce noise. In FIGS.
11A and 11B, a fixing unit 1013 is shown around motor 1011. The
mount isolates the motor from the housing to reduce noise.
[0051] The control system 1015 which can be a printed circuit
board, or the like, is configured to command the motor and thereby
activate opening and closing of the blinds. One or more buttons
1023a, 1023b can be positioned on the PCB and can provide a means
to command the device, such as an auto calibration, or the like.
Further, one or more power port 1020 is preferably located on the

via the motor 1203. Further, as discussed previously, the control
system 105 includes a communication board 1205 to provide for
communication with networked devices 1201, computing devices, a
home automation controller 1204, and the like. The control system
105 includes a calibration control 1209 configured to calibrate the
device. Further, manual rotary 1212 provides for a means of
control.
[0054] In FIG. 13, a flowchart 1301 depicts the method of
calibration. The autocalibration is activated, wherein the control
system operates to rotate the tilt rod to a completely closed,
downward position, as shown with boxes 1303, 1305. The control
system then proceeds to rotate the tilt rod to a completely upward
position, as shown with box 1307. The calibration tool then
calculates the proper current limit based on the force needed to
force the blinds closed in both directions, as shown with box 1309.
This data provides necessary details for the control system to
calculate a maximum down and up position, thereby calibrating the
device, as shown with boxes 1311, 1313.
[0055] In FIG. 14, a flowchart 1401 depicts a method of use of the
system discussed herein. During use, the control device is
installed within the blind headrail and is communicatively coupled
to the mesh network and network device, as shown with boxes 1403,
1405. The device is assigned a unique identifier, as shown with box
1407. The device is then activated, as shown with box 1409. It
should further be appreciated that the device may be activated
based on a command received through the interface and the control
system, or in alternative embodiment, as networked device
determines a criteria (such as temperature or light), a command is
sent to the device to perform a function. The device the alters the
tilt position of the blinds, as shown with box 1411.
