[0001] The present invention relates generally to the field of sanitary ware. More
particularly, the present disclosure relates to an ergonomic commode chair to provide
defecation facility to disabled, bed ridden patients, and old people.
BACKGROUND
[0002] Background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information
provided herein is prior art or relevant to the presently claimed invention, or that any
publication specifically or implicitly referenced is prior art.
[0003] Old age people, bed ridden patients, disabled persons and persons with other
such problems may find it difficult to do their daily chores, and even moving from one place
to another may become a cumbersome task for such persons. In such situations it becomes
difficult for them as well as other persons, such as relatives and caretakers, to monitor such
persons continuously, attend them each time, and take care of them.
[0004] Main problem corresponds to the defecation facility for such persons, and is
directly linked to the comfort and ergonomics of both the person and caretakers.
Improvement in the design of commode chair for such patients and disabled people,
especially who are having injuries or disabilities pertaining to lower limbs, is an area of
concern. Currently available low cost mechanisms for commode chairs are not designed in a
way that they can be used as a comfortable chair, with full sanitation facility. Also, the
mechanisms which have more ergonomics are so complex that their production cost is
generally too high. This is due to the use of advanced gear boxes, automation sensors,
controlling circuits and various other complicated devices for the same. Consequently the
cost of such complex mechanisms is high, which however, is estimated to be considerably
lower for this proposed design.
[0005] There are several proposed trajectories of waste bag that can be configured in
such chairs. For example, one of the configurations involves only the use of linear guide for
sliding the waste bag inwards, and it is not having the L –shaped trajectory of bag, and,
moreover, there electromagnet is also not used in the configuration. Such a configuration
could lead to a potential danger for users, because movement of sliding tray in such a
3
trajectory and that too even without any electromagnet to fix position of the tray, may pose an
injury to genitals of users.
[0006] Moreover, use of linear actuators to for moving detachable seat and sliding
tray may result in higher complexity in configuration and also may lead to an unnecessary
surge in manufacturing cost.
[0007] There is therefore need in the art to develop a robust, cost-effective, efficient,
ergonomic and user-friendly commode chair to overcome the above-mentioned and other
limitations of the existing solutions and utilize techniques, such as electromagnetism, driving
mechanism, gear mechanism to make the chair easy to use that can be meant to be targeted
for the “base of pyramid” people who have lesser ability to pay for the expensive sanitation
devices. In view of the growing awareness of sanitation in rural areas of nation, such a
commode chair could be the revolutionary game changer product.

12
wheel 142, hereinafter) that can be movably coupled to legs of the chair 100, thereby can
enable swift movement of the chair 100 from one place to another.
[00064] In an embodiment, an entity can manually operate the chair 100. In an
exemplary embodiment, an entity can speak or provide acoustic signals to operate the
commode chair 100 through devices, such as, but not limited to, button, mic, remote,
microphone, and the like. In an exemplary embodiment, the entity can speak and accordingly,
any or a combination of mic and microphone, can convert acoustic signals associated with
speaking of the entity to electrical signals. In an embodiment, mic and microphone can be
operatively coupled to the control unit through a communication network including, but not
limited to, Bluetooth, Wi-Fi, Li Fi, Zigbee, and the likes.
[00065] In another exemplary embodiment, the entity can manually operate the chair
100 through an input unit that can be operatively coupled to the control unit. The input unit
can include one or more buttons or a graphic user interface (GUI) based interface screen
through which the entity can give a set of inputs, the set of input signals can be transmitted to
the control unit from the input unit, and correspondingly the control unit can enable operation
of the chair 100 in a desired way. In another exemplary embodiment, the entity can manually
operate the chair 100 by interacting with one or more components of the chair 100.
[00066] In an implementation, based on acoustic input signals received or manual
operation or through the control unit, the second section 114 (also referred to as detachable
section 114, hereinafter) can move away from horizontal surface of the seat 102. The
detachable section 114 of the seat 102 can be moved with the help of a DC motor that can be
coupled to one or more small spur gears. In an exemplary embodiment, spur gear 134-1 can
be meshed with a spur gear 134-2, which in turn can be connected to a long shaft. As soon as
the DC motor turns on, the shaft turns due to motion of gears and hence the detachable
section 114 of the seat 102 gets lowered, leaving behind the empty space for the subsequent
entry of the tray 110. In another exemplary embodiment, the DC motor, the spur gear 134-1,
and the spur gear 134-2, all can be positioned on the right side of the chair 100 with respect to
the entity sitting on the chair 100.
[00067] In another implementation, movement of the second section 114can be
followed by linear movement of the tray 110 (interchangeably referred to as sliding tray 110,
hereinafter). In an exemplary embodiment, the tray 110 can include metallic seat, and at least
one disposable bag 112 (interchangeably referred to as waste bag 112, hereinafter), where the
bag 112 can be made from materials, such as, but not limited to, plastic, paper, rubber, and
the like. In an embodiment, space vacated by moving the second section 114, with help of
13
motor and gear mechanism, is utilized for the inward movement of the sliding tray 110,
which along with the waste bag 112 and metallic cover seat, moves to the innermost area of
linear guiderail, where it comes directly beneath the vacant area left previously by the
movement of the detachable section 114. The sliding tray 110 fits inside the Linear guide
rails, which can be situated beneath the seat 102 of the chair 100. In an exemplary
embodiment, Rack & pinion along with DC Motor can be positioned on the left side of the
chair 100.
[00068] In yet another implementation, once the sliding tray 110 occupies the
innermost position with help of the stimulation provided by DC Motor, pinion and Rack,
electromagnetic layer 126, which can be fixed along the periphery of the vacant area of the
seat 102, can attract the metallic cover seat. Once this procedure is completed, the waste bag
112 can be moved at a fixed position to receive waste, such as human excreta. In an
embodiment, magnetic force of electromagnetic area and enclosing area of linear guiderails
can ensure that the waste collection bag 112 is maintained in proper position during the
excretion activity by an entity.
[00069] In yet another implementation, once the defecation process is over, a
sequential process of activation of motors, electromagnet 126 and all other moving
components can be reversed with the help of the control unit, so that the chair 100 and all
other components can be re-positioned to the original configuration. In an embodiment, once
the reverse sequencing is completed and the sliding tray 110 is moved at the outermost
position, the waste bag 112 and the metallic cover seat both can be separated from the
assembly and can be emptied/ dumped at the suitable place. In an exemplary embodiment, the
waste bag 112 can be separated by sliding it out of the tray 110 and the metallic seat cover
can be simply pulled up from the top. Moreover, the detachable section 114 of the seat 102
can be made to regain its original position and hence the chair 100 can be re-arranged as a
normal “non-commode” chair.
[00070] Thus, it will be appreciated by those of ordinary skill in the art that the
diagrams, schematics, illustrations, and the like represent conceptual views or processes
illustrating systems and methods embodying this invention. The functions of the various
elements shown in the figures may be provided through the use of dedicated hardware as well
as hardware capable of executing associated software. Similarly, any switches shown in the
figures are conceptual only. Their function may be carried out through the operation of
program logic, through dedicated logic, through the interaction of program control and
dedicated logic, or even manually, the particular technique being selectable by the entity
14
implementing this invention. Those of ordinary skill in the art further understand that the
exemplary hardware, software, processes, methods, and/or operating systems described
herein are for illustrative purposes and, thus, are not intended to be limited to any particular
named.
[00071] While embodiments of the present invention have been illustrated and
described, it will be clear that the invention is not limited to these embodiments only.
Numerous modifications, changes, variations, substitutions, and equivalents will be apparent
to those skilled in the art, without departing from the spirit and scope of the invention, as
described in the claim.
[00072] In the foregoing description, numerous details are set forth. It will be apparent,
however, to one of ordinary skill in the art having the benefit of this disclosure, that the
present invention may be practiced without these specific details. In some instances, wellknown structures and devices are shown in block diagram form, rather than in detail, to avoid
obscuring the present invention.
[00073] As used herein, and unless the context dictates otherwise, the term "coupled
to" is intended to include both direct coupling (in which two elements that are coupled to
each other contact each other)and indirect coupling (in which at least one additional element
is located between the two elements). Therefore, the terms "coupled to" and "coupled with"
are used synonymously. Within the context of this document terms "coupled to" and "coupled
with" are also used euphemistically to mean “communicatively coupled with” over a
network, where two or more devices are able to exchange data with each other over the
