Description

Compared with other everyday products (such as motor vehicles, electrical appliances), beds still do not have a special place in society, in contrast to the fact that you spend about 1/3 of the day in bed, so this the most intense and longest used object.

Of course, there are many very high quality mattresses and beds that a small percentage of society uses, but the general public attaches less importance to them.

These considerations led us to locate a high-quality bed in an area where it can be marketed and many people pay attention to it.

In the hotel things are used more intensively, frequent guest changes mattresses are much more stressed. Therefore, the claims are higher than in the standard private sector.

In the truck sector, we are in a very high-quality (expensive) environment. A truck tractor costs several hundred thousand euros, while the mattress in the driver's cab currently costs about 60, - € to 150, - € and is usually a simple foam.

On the current state of the art in mattress and pneumatic development:
At present, various manufacturers are offering functioning, but neither "intelligent" nor fully automatic controls for air beds.

Beds available on the market can not adjust completely automatically to the sleeping person. Every sleeping person has to program the bed first, only then can the data be saved. However, the bed does not "recognize" the user.

This type of necessary initial programming is frowned upon in the hotel industry, as the guests would be forced to a laborious study of technology, which is not possible especially in the luxury class.

The mattress industry currently offers no possibility worldwide, especially hotel guests when changing the hotel z. B. within a hotel chain in each case the "same" bed.

Air beds have hardly been used in the hotel industry so far, only a few individual hotels have used air beds in hotels.

An intelligent controller, which can also be integrated into modern hotel management and booking systems, does not exist at all.

Never before has a bed been developed that allows one to travel through the user's APP on their mobile phone. This development is ahead of the current marketed products that are made for a single user in their own home.

The demands on the development of the control initially seem indeed simple, the actual claim to the beds straight with hotel chains is extremely complex, since the guest can freely book a bed in another room of another hotel. It can be in a double bed on the left or right, it can get a wider or narrower bed, a shorter or longer bed. These parameters alone radically change the conditions in which the controller must adapt.

Other influences such as the location of the hotel (high humidity, altitude, etc.) or the climatic conditions within the building have a major influence on the quality of sleep and thus on the function of the controller, which must adapt these conditions to the user.

The use of intelligent controls in truck cabins, as well as in the hotel, are users (sleepers) in changing environments. In addition, the truck driver, who uses this and has the same bed at home, can also take "his" bed, and in addition to sleep by APP in between in a hotel with the same facilities.

The data that the controller generates in the bed are very individual and, in principle, highly sensitive data. These data can not be stored automatically for reasons of data protection.

The app itself is initially just the download of a "remote control", which can be used instead of the existing remote control or other existing operation in the hotel room. This also just a missing remote control can only be replaced.

Only through the intentional storage of the data are these stored in the controller and stored personal. These are then deposited via the central booking system via the respective booking automatically in the next hotel for the booked bed (room) and the guest already gets "his" bed. The fuzzy logic constantly refines the sleep result.

If the guest downloads the APP on his mobile phone, he can also save these functions on his mobile phone, and these in z. For example, you can take a hotel with you in the same or a different hotel chain, or use it at home in your own bed.

If the hotel guest has the same bed at home, he can use his cell phone to transfer and use the data already collected to the control system in the hotel. He can use this without saving in the hotel software.

A truck driver z. B. can also generate the data in a mattress, either in the truck or at home, and then transfer the data to the other bed.

1. Initial situation and motivation

1.1. Initial situation in the hotel industry

Development of an innovative, intelligent and highly sensitive pneumatic mattress.

This system, which has been developed according to the latest findings in sleep research, aspires to set new standards worldwide in the production of pneumatic mattresses (= air beds) in order to revolutionize the hotel market in particular.

Based on the constantly increasing pressure of innovation within the big hotel chains (number of hotel rooms in the 20 largest hotel chains: ≈ 5,929,000, number of beds in the 20 largest hotel chains: 10,672,200), this mattress can contribute to the individualisation in the hotel room. The smaller hotel chains are countering the pressure of the big hotel chains with their individuality and innovation. The little ones challenge the big ones to take on this individuality as well and thus drive the actual profitable progress forward.

1.2. Initial situation in the truck cabin

New standards are also being set in the area of truck cabins. Again, only relatively simple foam mattresses are currently installed, which allow in principle to low ergonomic lying. However, the ever-increasing demand for performance on the part of the driver requires a rapid and effective recovery in the driving breaks and thus a decisive increase in performance, which should be supported by effective sleep systems in the future.

1.3. New solution for pneumatic mattresses (= air beds)

Most of the airbeds currently on the market have a single large air chamber or two or three air chambers "one behind the other", ie a split lying surface, embedded in a foam frame.

• (a) Entwicklung einer adaptiven MSR-Technik (= Mess-, Steuer- und Regeltechnik) für die Intelligente Pneumatik-Matratze;
• (b) Entwicklung einer komfortablen Pneumatik-Lösung, bestehend aus zwei oder drei Einzelluftkammern, die je Luftkammer durch eine separate MSR-Schleife betrieben wird, jedoch als Luftrahmenlösung mit innenliegender Grundkammer als vollflächige Liegefläche, mit darüber liegender Funktionskammer, die aufgrund ihres wesentlich geringeren Luftvolumens sensibler auf Änderungen der Volumenströme in den Sensoren bei Bewegungen auf der Matratze reagiert.

Our new product concept provides for two main focuses:

• (a) development of an adaptive measuring and control technology for the intelligent pneumatic mattress;
• (b) Development of a comfortable pneumatic solution, consisting of two or three individual air chambers operated by a separate MSR loop per air chamber, but as an airframe solution with internal base chamber as a full-surface lying surface, with overlying function chamber, due to their much lower air volume more sensitive to changes in the volume flows in the sensors during movements on the mattress.

2. State of the art

The current MSR techniques for airbeds are mostly located outside the actual mattress, resulting in difficulty or handling issues. Under the bed are then the control unit, the hose excess length, the separate power supply and the corresponding supply lines.

The external connection of this control in these air beds leads through the mattress cover by means of an air hose and unsightly cuts through the bed base (box spring base, slatted frame, etc.). Improper installation of the hose can lead to kinking and thus to a malfunction of the system.

By this arrangement of the previous solution, the state can be unsightly and unhygienic, especially in the hotel under the hotel beds.

The size and shape of these boxes / housing makes it impossible to install directly into the foam frame of the mattress / air bed. There are no tests or approvals for the previous manufacturers.

• (1) Die Pumpe arbeitet nach dem Funktionsprinzip einer Linearpumpe mit ≈ 20 Liter Luftleistung pro Minute.
• (1) Das Laufgeräusch der Pumpe ist relativ laut und beträgt im offenen Zustand ≈ 77 dB, im geschlossenen und damit betriebsbereiten Zustand immerhin noch ≈ 62,5 dB.
• (2) Als weiteres Bauteil ist ein dreiteiliger Ventilkopf in einem einfachen Kunststoffgehäuse eingebaut. Dieser Ventilkopf ist problembehaftet, da die Dichtungen der Ventile sehr weich sind und sich leicht klebrig anfühlen. Dieses ist auch einer der Grund dafür, dass die Ventile von Zeit zu Zeit verkleben und das Gerät damit nicht mehr funktioniert.

In addition, the devices are relatively susceptible to errors and errors, since they are usually high-volume devices that are equipped with very simple components. The solution approach in the prior art has the following technical disadvantages or shortcomings:

• (1) The pump works according to the principle of operation of a linear pump with ≈ 20 liters of air per minute.
• (1) The running noise of the pump is relatively loud and in the open state ≈ 77 dB, in the closed and thus operational state after all still ≈ 62.5 dB.
• (2) As a further component, a three-piece valve head is installed in a simple plastic housing. This valve head is problematic because the seals of the valves are very soft and feel slightly sticky. This is also one of the reasons why the valves stick together from time to time and the device does not work anymore.

In other manufacturers, the control device is indeed arranged in the mattress in the foam frame, by several connections outside the mattress or by a likewise lying on the ground power supply, there are also problems with "cable salad" outside or below the bed.

These problems lead in the application area hotel to massive disruptions to the operation of the hotel in the room cleaning, which is difficult, since when vacuuming under the bed, the control unit or the power supply in the way.

2.1. Operation of the valve head in the prior art

The housing has two inputs for the linear pump, two outputs for connecting two air chambers (single or double bed) and an opening for blowing off. With the double bed, only one bed part can be operated, even if two remote control parts are connected.

The three valve heads close the two outlets as well as the opening for blowing off. The two pump connections lead directly into the valve chamber.

In the function "inflation", an outlet is opened by means of a valve, the bed becomes harder. In the function "Blow off", an outlet and the blow-off opening are unlocked by means of two valves, the bed becomes softer.

Another major drawback is the type of noise, which is relatively loud and represents a "cheap-looking" background noise. The Aufblaston manifests itself in a loud buzz of the linear pump, the Abblaston produces a significant hiss. In between there are clearly "pop" sounds for switching valves.

Disadvantage 1:

No consistent, complete complete solution with coordinated subsystems consisting of electronic, pneumatic and three-chamber mattress system.

Disadvantage 2:

Relatively large noise development due to the previously used valves, pumps, other actuators up to more than 77 dB (A). In this noise, an automatic adjustment or tracking can therefore not be done with the previous system.

Disadvantage 3:

Relatively low service life of the mechanical components in hotel operation. Contrary to the manufacturer's information, which has a service life of 3,000-5,000 hours, significant numbers of controls are already eliminated within a few months or within the first one to three years. The current failure rate of approximately 1-5% is unacceptable in hotel operations, as operational failures automatically lead to non-bookable room failures, and thus high failure losses are caused.

Disadvantage 4:

The blowing off of the bed only works flawlessly due to the pressure that a person lying on it creates. In the hotel, however, the basic setting must be set without a person lying on it, as a result of which the basic setting "0 mbar" is not always reached safely.

Program sequence for automatic programming

The following section shows how the self-learning process takes place in each case with a newly sleeping on the bed.

Hotel, new guest:

• - By room reservation (new guest) is the mattress in basic position.
• - The basic settings are parameters that measure the size of the mattress, the air pressure in the room, the humidity and the height of the mattress. From this microclimate, the hardness setting is carried out on the basis of a curve to be created for the basic setting.
• - The characteristic to be calculated results from the ratio of pumped air volume / degree of hardness to the required time of the pumping process. On the basis of this data acquisition (= amplitude, frequency, time duration) the differences between the different mattress sizes and locations can be determined and stored.
• - Another finding is the fact that a person turns on a normal good mattress about 50-80 times a night in bed or changes its location, but on an airbed only about 20-30 times, as this system is a significant has better pressure balance. Tips in the air pressure curve to be measured during sleep allow these body movements to be precisely recorded. In this way the sleeping person can be animated by pressure change to move (rotate) more or less frequently.
• - The air pressure in the mattress corresponds in the basic setting to the air pressure of the surrounding space.
• - Thus, a guest is already so comfortable without programming that the mattress is superior in comfort compared to a standard mattress. This point is important so that no guest complaints arise.
• - Air pressure and acceleration measuring sensors installed in the air topper (upper layer of the three-chamber mattress) will monitor heart rate, respiratory rate and movements (calm or restless); Temperature and humidity sensors are used to query the temperature of the bed and the humidity in the bed.
• - Through in the base chamber (lower layer of the three-chamber mattress) located measuring sensors are also queried by pressure and air acceleration measurements movements in the mattress.
• - The values of the upper chamber are very accurate and very fine readings, and provide information on the well-being of the sleeping person.
• - The measured values of the lower chamber represent difference values to the upper measured values, so it can be determined whether pressure points develop in the sleeping person (eg in the case of very heavy persons).
• - With these results of the two superimposed chambers, the mattress settings can be tracked, it is expected that the pressure in the lower chamber must be lower for very heavy people, as in lighter persons. An adaptive adjustment of the two chambers to each other is an essential development step.
• - To improve the quality of sleep (adjustment of the REM phases), the pressure in the upper chamber must be varied.
• - Due to the much smaller air volume in the upper chamber can provide more accurate measurement data than conventional single-chamber air beds.
• - These basic data recorded in the first phase and the resulting first follow-up of the mattress already lead to a very individual and pleasant sleep phase.
• - By rhythmic changes in the mattress by means of air pressure change, the sleeping person is accompanied in the different phases of sleep. Through a self-adaptive logic (fuzzy-logic) so the individual sleep behavior is automatically detected and continuously improved. It creates a complex sleep profile.
• - By booking the guest can save the data via the remote control or the APP.
• - The APP is available in the hotel via hotel TV or infotainment for retrieval. The guest can thus load the data on his cell phone and "take along" to evaluate it at home.

Hotel, regular guest:

• - The regular guest receives a bed that is already preset by the stored data in the booking, his sleeping habits are recorded and the automatic adjustment phase is canceled. Through ideal adaptation, the sleeper reaches his important sleep recovery phases more quickly.
• - He can be aroused by his own biorhythm, the mattress "wakes" him on demand slowly from his sleep in favorable phases.
• - Through constant learning of the control, the guest is perfectly bedded.

Truck, additional features:

• - For the use of the control and the multi-chamber bed in the truck additional parameters can and must be recorded.
• - The mattress detects how long the truck driver slept during his breaks. Depending on this, an adaptive break recommendation can be issued via the info service in the truck.
• - In addition, the controller could provide evidence of the sleep activity for the truck driver in a possible control, as the exact sleep times are included.
• - With the built-in microphone control, the external noise is measured and eliminated with an anti-noise device in the truck cabin.

Individual settings by the user himself:

• - The user can also make their own settings via remote control or with the APP loaded on his mobile device.
• - It can be harder or softer set the degree of hardness of the mattress. For example, for watching TV or doing sports in bed, the user may need a very tough setting, which he does not use to sleep.
• - He can decide if he wants to wake up with a biorhythm curve. Here is the example: A user wants to wake up at 7am. His biorhythm curve, however, indicates a high phase at 6 o'clock. In order not to let the guest sink in the last hour into a new deep sleep phase, from which he can be woken up only with difficulty at 07.00 clock, is changed from 06.00 clock, the air pressure in the mattress, z. For example, harder so that the sleeper rotates more often and he can not sleep so deeply. It can be directed precisely to its ideal point of growth.
• - He can choose whether his data should be stored (eg in the hotel).
• - The controller must be able to interpret all manual settings and incorporate them into the complex data sets as relevant or irrelevant.
• - The collected data can be read with the software on the APP and evaluated with graphics or tables his own sleep quality.

General automatic settings:

• - Through an automatic pressure loss detection from the collected data information about the technical condition can be transmitted to the user or to a responsible hotel staff at an early stage.
• - An optional integrated hygiene monitoring reports the hygiene conditions of the covers of the mattress to the responsible personnel in the hotel. Thus, the regular cleaning of the covers can be planned accordingly on time.
• - An optional pressure distribution measurement with about 1,000 pressure measuring points on or in the function chamber enables the determination of the actual pressure distribution of the person lying down. Due to the fully automatic adjustment of the pressures in the function chamber in relation to the basic chamber, pressure equalization during sleep can be optimized.

Thus, the regular cleaning of the covers can be planned accordingly in time, connection via potential-free input ( 3 ). - An optional pressure distribution measurement with about 1,000 pressure measuring points on or in the function chamber enables the determination of the actual pressure distribution of the person lying down. Due to the fully automatic adjustment of the pressures in the function chamber in relation to the basic chamber, pressure equalization during sleep can be optimized. Data connection not shown in block diagrams.
