This is how virus get spread especially in restuarant and office environments - exhaled air spread accross the board.

Looking at this diagram then, what can you do to prevent the exhaled air from spreading? This is even more critical when you have an enclosed space like that of a restaurant where there is very little of air ventilation!

New Anti Covid Furniture to fight Coronavirus

An Anti Covid Furniture in the form of a table attachment is our solution to prevent the spread of Covid 19. It forms a part of the system of directing air from the top to the bottom ; as a better way to prevent the spread of pathogen amongst the occupants of a room. This is because health experts had determined that the Corona Virus is partly spread through fine particles (aerosols) that we inherently exhaled from our mouth and nose. It was also found that these fine particles can remain airborne and floating for a couple of minutes whilst waiting for it to be inhaled into our lungs with us sitting next to the infected person! So its all about the air, the floating air particles in particular and we will have to deal with it perhaps for a long period; it is most likely that the Covid 19 will become an epidemic. When we talk about the air, we will have to touch on the ventilation issue. Conventional thinking is that fresh air is vented into the space from one side of the wall and is then forced to flow to the other side of the wall - from left to right and vice versal. Now if we were to take a case of two people sitting opposite each other - then we will find that depending on which way the air were to flow, it would be possible for the other guy sitting in the headwind position to catch the virus. It would then be obvious that the air is travelling in the wrong direction as far as the spread of virus is concerned. In order to correct the situation, air should be made to flow from the top and then to the bottom where it is extracted to be channelled to a filtration chamber. The filtered air will then be either recirculated or better exhausted to the outside (preferably filtered and sanitized). The preferred embodiment is shown in the diagram below

First of its kind - a technique to exhaust exhaled (expelled from the mouth and nose) air from a dinner sitting at a dining table. This embodiment shows a peripheral attachment with an internal hollow is attached to the table top edge. An internal channel connects the edge facing the occupant and the vacuum device. Air that is being exhaled from the occupant is then being judiciously sucked in and thence channelled to the vacuum where it would be led to be filtered and sanitized. The filtered air can then be recirculated or better still outlet to the outside. If the air were to be exhausted to the outside, then it would be best to have a proper piping system either laid above the floor or having it laid under the floor – sort of underground channel.

Since the peripheral attachment is designed for the restaurant and office environment as a quick retrofitting solution to better manage the air in an Anti Covid exercise, it could however be better to have it integrated into the whole air conditioning and ventilation system when designed from the start. As you would have noticed from the diagram shown below, you will see that there is an air conditioned air coming out from the central piece of the table. Indeed we can have an integrated air cooler such that it will take the place of a centralised air conditioner as it would be more fuel saving as it would have to only cool the air that is surrounding the occupant – you will not have to spend fuel cooling the ceiling area or the spaces that are far away from the occupant. The diagram also shows of an umbrella like canopy to divert cooled air down to the occupant – this canopy can also be adjusted up or down to suit the preference of the occupants.

In order to reduce our energy cost whilst fighting the spread of coronavirus, we will need to redesign our air ventilation system.

Let us look at our air ventilation system which we have been using for decades. It was a design to suit the air conditioning technology of the time – there was very little need for air ventilation at the time. It was of course understandable because having air ventilation will mean energy lost and thus higher fuel bill! But we are now confronted with a dangerous disease – one that spread fast. The experts including the people at CDC have raised the need to include ventilated air into our system so that we have some fresh air to breathe in. A circulating air can help disperse off the virus which was found to be able to spread through the air. We are proposing that an underfloor hollow be built into our room space – this hollow or channel will assist us to exhaust out the air from the room. There should be another inlet for fresh air to vent in and it is conveniently placed at the top corner of the room. With such a system will mean we have another problem – that of energy leakage. So we will need to be able to tweak the air conditioning system and we are suggesting that we use an intelligent air conditioning system – that is able to sense the number of occupant and thus tweak its powering capability to suit the environmental conditions.

An underfloor channel will serve three purposes – first to exhaust out the stale air and second is to integrate a cooling (or heating) system with a purposely built centralised air conditioning system. If we are talking about an effective ventilation system we must ensure that sufficient fresh air gets into the room – also sufficient foul air getting out. The so called underfloor channel can be conveniently hidden from sight by way of a covering layer – it could be made from flooring material. It could also be built in like the heating chamber of a heated room space but whatever form it takes it would be best to build it from the beginning stage. And thirdly, the underfloor channel can serve as a conduit of electricity - you can have wireless charging on the floor. So these are the ideas that the HVAC engineers have to consider when they are doing a reengineering exercise – for the purpose of riding off the ever increasing forms of virulent pathogens.

This table air conditioning system will save you 60% of your fuel bill - it also incorporates an anti covid air exhaustion system!

You might wonder what is table air conditioner?

Table air conditioner is a table with an inbuilt air conditioner - it could either be a compressed refigerant type or an electronic air cooler (or warmer). It is of course new and never seen before. Table Air Conditioner is especially design to keep you cool and at the same time extract out the air that you expelled from your mouth and nose so that others don't breath in what you breath out while sitting at the dining table. The air conditioner (evaporator) is built into the table stand which inherently is of a bigger size than standard. Air is usually being drawn into the evaporator chamber through a vent at the bottom of the stand. But in this case it is being drawn from the discharge vent of the vacuum/filter/sanitizer combo. The discharge from the vacuum is being sanitized to get rid of virus so it is the cheapest option to use it for cooling (or heating). However having such a system will require the heated refrigerant to be bleeded out of the room like that of a split air conditioner. It is the same with an electronic type air cooler otherwise the room temperature will remain the same or worse still, slightly warmer. In this case, it would be better to bleed out the warm fluid to the outside through an inbuilt underfloor channel. If however an underfloor channel is not available, then a piping system will have to be used - it would then not look aesthetic! You will also notice that there is a sort of cup shaped deflector hanging at the top of the table - this is to help deflect the cooled air to the occupant instead of to the ceiling. Alternatively the cup shaped deflector is connected to the table via a lamp shade stand - and made adjustable like in the diagram shown below.

sofa air conditioning

This sofa air conditioning system includes the extracting and expelling of exhaled air from the occupant.

The table air conditioner is a new concept designed to save energy consumption as well as to introduce a safe ventilation system in the light of spread of contagious deceases. As far as furniture is concerned, there have been efforts to enwrap furniture with anti-bacteria coatings to stave off the spread of virus. You could also spray the floor with anti-bacteria coatings like titanium dioxide but when we come to the very infectious deceases like coronavirus then there is very little thing else that we can do - because the virus is not only spread through particles but through air droplets that is exhausted through the mouth and nose. So we will need to tackle the air which in the CDC’s account should be beefed up through better air ventilation – we do have very little of ventilation through our present air conditioning system.

Table air conditioning system is a two in one system where you can not only air condition a space (like a dining space) you can also do a bit of air ventilation especially at the space where people expel their exhalation – where exhaled air from the mouth or nose may be contaminated with virus. In this system, air is cooled through an inbuilt air cooler in the table stump. Cooled air is then directed upwards towards an air diverter (with inbuilt lamp) which will then direct cooled air towards the diner sitting next to the table. Exhaled air (could be contaminated) is then being drawn into the table via a table edge attachment connected to a vacuum. The air is then filtered and sanitized and then fed to the evaporator of the air conditioning system. Alternatively the filtered and sanitized air could instead be exhausted to the outside through an underfloor channel.

As you would have noticed, the air conditioning system only need to cool the space around the table so it would not waste fuel as compared to the conventional system where cooled air is required to cool the whole room. Furthermore, the air conditioning system could be enabled with an intelligent system to only direct its air to the region of the occupant – no occupant means it will automatically shut down or throttled. This we believe is the future of air conditioning (or heating) as we are concerned with the greenhouse effect through the use of fossil fuel. This is also how we micro manage our environmental spaces – to further add to the micro management system there will be a need to add additional air conditioners to the place where people sit. But using micro management will mean added start-up cost as more units of air conditioners will be required although we could design a centralised air conditioning system by connecting all the micro units together (but run differently) to enjoy energy efficiency. The same can be deployed in an office environment.


It is also a better solution to integrate the exhausted air from the filtration part to the air conditioning part and this could be achieved by routing the exhaust air to the air conditioner intake point. As for the air conditioner system, we could have the conventional split air system by having the heated air from the evaporator being led to the outside by means of a channel or piping laid under the floor – assuming that the underfloor channel is built up from the start. It would also be obvious that an underfloor channel will serve an important function as far as an Anti Covid exercise is concerned. The underfloor channel could also serve as a heating chamber during winter. It could also double as a channel to draw away the washed water during floor washing exercise – another vacuum can be added to do cleaning as restaurants need to be kept clean all the time.

The Top to Down Air Ventilation system epitomises the future of air ventilation as a means to combat the spread of infectious diseases. It’s not only for the Covid fight but also for anti-flu fight and other diseases that has yet to come. A fundamental shift will need to be taken for retrofitting our ventilation system as the conventional ventilating principles were enacted during the early times of air conditioning. There should also be another exercise to better design our air conditioning system as it is already outdated because we will need to design a greener system – air condition and heating in our offices and homes take away twenty five per cent of our fuel bill. It would be even better if a smart/intelligent air conditioning system is installed. And still referring to the air conditioning unit of the above diagram, we could also use a solid state electronic air cooling unit such that it would provide a more silent mode of operation – it is also suitable because there is a smaller space to cool.

An integrated air conditioning and ventilation system with underfloor channel.

In cold climates, it is often the norm to have an underfloor heating system - so channels will be built to incorporate heating elements. This is usually an after thought construction as it was not in the original plan of the house to have underfloor heating - it would inevitably add to the cost. However, we would like to propose that an underfloor channel be built from the start as it will have many uses besides the incorporation of underfloor heating. One of the new use of an underfloor channel is that of exhausting exhaled air from the room thus offering a way to better ventilate the room - this become an important tool to fight coronavirus. The other future use is that of offering a channel where electricity can be tap through either wireless induction or radio wave charging - these are a bit futuristic but they are now available. Then there is an additional use - that of a convenient way to discharge floor cleaning waste water.

The future of office environment - brought to you by a team of inventors who are concerned with how we can prevent the spread of coronavirus disease.

working table vacuuming

Here is a peep at the office of the future. Even from before the Covid 19 Pandemic, we were aware that the office environment was a place where flu can spread easily. Just have someone cough (the incessant kind) in the office and you will see somebody else pleading for grant of sick leave the next couple of days. It was easy to catch the flu and it was also easy to feign catching the flu because someone did went on sick leave! But you might say we were used to it already as nobody else apart from the manager did make his complaint known. So with the new era of pandemic going on and on, we will need to tackle this problem of spreading diseases. We have come up with a solution and as you can see in the diagram, we have designed a table attachment that can help us suck in the aerosol particles (might contain pathogens) as they were exhaled from a person that might harbour the virus. There you have it, the future scope of the office where you can work in a safe environment – as long as the table attachment is powered to suck in the exhalation.

A bit of background on business furniture in the light of the coronavirus pandemic – there is this urge to keep our furniture clean off the coronavirus. Since it was established (vaguely) that the coronavirus can stay alive for a day or two on surfaces, we were therefore urged to keep our surfaces clean by dosing it with disinfectants – including all the furniture that we sat on. There was this directive that we will have to spray alcohols on surfaces that might hold the viruses just so that the viruses were killed. Then there was this directive that office desk be segregated by the fixing of a transparent piece of plastic to prevent the virus being blown over to the next table. Also we were advised that tables and chairs have to be wiped off with disinfectants. Hands too needed to be cleaned with alcohol – as are places where we use to touch be converted to touch-less devices. All these are because they have found that the coronavirus can stay alive for twenty four hours after they have been expelled from our chest – that was the primary reason.

However, we were later told that the coronavirus was also transmitted by aerosols – small sized particles that can remain floating in the air for a few minutes! And that lead us to begin taking precautions to protect us from the airborne virus – so our next thing to do is to shroud us away from the aerosols. But aerosols being airborne are another thing altogether as we can’t go and spray alcohol all over the place, including those spaces that we don’t have a right to. After having wasting a good amount of time thinking over the problem, we then came to a conclusion of redesigning the whole environment – not just for the moment but also for the long haul as it is predicted that the Covid 19 pandemic will be with us as an epidemic, what more the fast mutations of the virus. Thus we have redesigned the furniture to suit the times – including tables, chairs and floors. As a result the tables of the future will have the ability to extract the air that is exhaled by the person, the working desk too will have the ability to suck in the air given out by the office worker. In all you can now dispense with the wearing mask, the spraying of disinfectants and the worry about not getting fresh air through good ventilation – this is done by introducing a flow out channel under the floor.

car seat vacuuming

What about when you are in a car? This is a solution for you to get rid of exhaled air when you are in a closed environment like that of a car. Here you will be able to see that exhaled air (might contain pathogens) is conveniently channelled into a vacuum and not into another person's nose. The extracted air is then sent to be sanitized and filtered and recirculated. The vacuum seat is made flexible and portable, so that you can bring along to another car or back home where you can place it over your sofa seat. There is also a portable battery to go with it which will power it for twenty minutes - it has also a connection to the car's electrical output. This solution might be made mandatory in future cars and public transports as these spaces can be the most likely space where virus spread - including how airplane spaces are designed to help extricate out the passengers exhaled breadth.

This is how exhaled air from the passenger is sucked out of the aircraft cabin space so that others will not have to inhale the contaminated air.

Public transport systems are now on the spot light as they have become places where the coronavirus is spread. As it is the public transport system was not design to prevent the spread of diseases even though we know that is where influenza is easily spread - but we were able to tolerate it. Since the arrival of the Covid 19 pandemic, we are now aware that we will have to redesign the ventilation system of these public transports - it also include public places like offices and shopping malls. It will also cost a bundle to implement but we have to start somewhere.

All systems are patented - licensing is available though.
