[0005] Amidst the evolving landscape of transportation vehicles, such as aircrafts, safety agencies and manufacturers are confronted with the challenge of accommodating increasing personal electronic devices usage and need to charge within the transportation vehicle environment. This challenge is particularly pronounced in areas such as the galley, lavatory and stowage environments, where personal electronic devices may be left unattended for extended periods. Unattended personal electronic devices can catch fire. The current state-of-the-art approach to deal with fire relies on the manual intervention of vehicle attendants to identify smoke emanating from personal electronic device fires and mitigate the situation by extinguishing or cooling the fire using a manually administered bottle of water or other fire extinguishing devices. However, ongoing development of a new solution is encountering challenges due to the confluence of specific requirements.

[0006] There is therefore a need to develop an improved solution for charging electronic device(s).

[0033] Description of specific embodiments of the invention

[0034] Description of preferred embodiments of the present invention are hereafter described with references to figures, but the invention is not limited by these references. In particular, the drawings or figures described below are only schematic and are not limiting in any way.

[0035] The invention concerns a compartment for charging at least one personal electronic device (hereinafter PED), for use onboard transportation vehicles. The compartment comprises an inner space suitable for receiving at least one personal electronic device and at least one electrical insert for charging the personal electronic device. The compartment also comprises a waterline connection, the connection comprises a material being configured to undergo a transformation when exposed to a temperature above a predetermined temperature threshold, the transformation releasing water into the compartment. Thus, in case a fire occurs in the compartment, notably due to the charging of the personal electronic devices and the overheating of the battery, the water is automatically released in order to extinguish the fire. In that sense, the compartment for charging the personal electronic device(s) is improved.

[0036] Figure 1 illustrates a compartment 10 according to the invention. The compartment 10 can be used in a transportation vehicle. The vehicle can be a train, an helicopter or a boat (yacht). Also, the vehicle can be an aircraft. In the following, any reference to an aircraft is a non-limitative example of a vehicle. The vehicle may transport a crew. The vehicle may transport passengers or not, such as military or cargo vehicles.

[0037] Compartment 10 can accommodate one or more personal electronic devices 11 for charging. A personal electronic device 11 (or PED hereinafter) is an electronic device owned by an individual. PED 11 is a portable device owned by the owner (PED standing for personal electronic device or portable electronic device). Examples of PEDs are laptop computers, tablets, e-readers, smartphones, MP3 players, electronic toys or wearable devices for care and hygiene, etc. In the following, reference will be made to PED or PEDs 11 , without restricting the scope of the invention, the compartment being suitable for accommodating one or more PEDs. PEDs first appeared in the late 1990s and early 2000s. Their use then spread rapidly. Since 2010, crews have started to use tablets and phones in the cabin and / or cockpit. Original Equipment Manufacturers (OEMs) and agencies such as the European Aviation Safety Agency (EASA) are faced with the challenge of accommodating the use and recharging of PEDs in the aircraft environment. Compartment 10 is a response to the increased use of PEDs and therefore the increased need to charge PEDs.

[0038] The compartment 10 comprises an inner space 12 suitable for accommodating at least one PED 1 1 . The size of the inner space 12 is defined according to the number and size of the PEDs to be accommodated and also according to the space available in the vehicle. The inner space 12 is delimited by the side, top and bottom walls of compartment 10. The PEDs 11 can be stored in a loose or orderly fashion in the inner space 12. The PEDs 1 1 may be separated by partitions. The compartment 10 may comprise one or more doors 14 to close the inner space 12 and for access to the inner space 12. The doors 14 may be pivotable, for example, about a vertical or horizontal axis. Doors 14 can slide horizontally or vertically. The doors 14 enable the PEDs 11 to be confined inside the compartment 10. The doors 14 enable the PEDs to be concealed from the view of any third party. Doors 14 can be locked. The doors 14 may extend over the full height of the inner space or only part of the height, such as two-thirds or half the height as a matter of example. As indicated below, the doors 14 can also be used to contain a fire 15 started by a PED 11 inside the compartment 10 and prevent the projection or propagation of gases and fumes. Walls and doors are fire resistant.

[0039] In order to ensure charging of the PEDs 1 1 , compartment 10 comprises at least one electrical insert 13 for charging the at least one PED 11 . The number of electrical inserts 13 depends on the number of PEDs that can be accommodated within the inner space 12. The electrical insert(s) 13 are connected to a power source located close to the compartment 10. The electrical insert(s) 13 may be a conventional power socket, and several electrical inserts may be provided in accordance with the standards of different countries. The electrical insert 13 may also be a USB socket.

[0040] Further, compartment 10 comprises a waterline connection 16. Connection 16 is linked to a waterline 17. Connection 16 allows water to be conveyed into compartment 10. In particular, the connection 16 allows water to be conveyed into compartment 10 to control or even extinguish a fire that could occur in compartment 10, due for example to a faulty electrical contact of a PED 11 under charging. Connection 16 is connected to the waterline 17. The connection 16 comprises a material 18 being configured to undergo a transformation when exposed to a temperature above a predetermined temperature threshold. In other words, part or a section of connection 16 is made of this material 18. The transformation of the material 18 releases water into the compartment 10. In the event of a fire, the temperature in the inner space 12 rises and once the predetermined temperature threshold is reached, the material 18 undergoes the transformation that triggers water releasing. In this way, the compartment 10 enables the fire to be dealt in a quick and automatic manner - and preferably without the need to open the doors 14. No intervention of the crew is required. This means that the PEDs 11 can be left unattended, particularly during a charging cycle. For example, the connection 16 and in particular the material are located in an upper zone of the inner space 12. This is because the temperature of the air above the flames of the fire 15 rises rapidly, enabling the predetermined temperature threshold to be reached quickly in this zone and therefore triggering the transformation of the material. On figure 1 , flames of fire 15 are schematically represented on the upper part of the inner space 12.

[0041] The transformation of the material 18 is not limited to one type of transformation. Heat triggers the transformation. Transformation can be destruction or explosion of the material. The transformation is for example melting, expanding, bending, breaking or burning. The material 18 is, for example, glass, plastic or metal or any other material capable of undergoing the transformation above a predetermined temperature threshold. For example, heat causes glass to break or metal to expand or bend or plastic to melt or burn.

[0042] The waterline 17 may be maintained under pressure or not. The waterline connection 16 is thus suitable for releasing water by pressure or by gravity in the inner space 12. The release by gravity is easy to implement. The release by pressure extinguishes the fire rapidly.

[0043] The predetermined temperature threshold is defined according to regulations and / or according to the temperature at which a fire can be caused by a PED 1 1. This threshold is preferably above the PED 11 overheating temperatures, so as not to trigger the water release if there is no fire. For example, the threshold may be between 55°C and 110°C. Other thresholds are also possible, notably in function of the type of PED that would be accommodated in the compartment 10.

[0044] Connection 16 may have one or more sections made of the material 18 being configured to undergo the transformation, the section(s) releasing water into the compartment. For example, the section may be a glass or plastic tube that undergoes a transformation such as melting, breaking or burning. The destruction of the material making up the section allows water to be released from the connection 16 into the inner space 12. As matter of other example, as an alternative or in combination with said section, connection 16 may also have one or more sprinklers 20. The sprinkler 20 is triggered to release water in the compartment by the material being configured to undergo the transformation. For example, the sprinkler 20 has an ampoule containing liquid which expands under the effect of heat. The expansion of the liquid causes the glass making up the ampoule to transform by explosion as from the predetermined temperature threshold. The destruction of the ampoule triggers the sprinkler 20 and the release of water.

[0045] The compartment 10 is a part of a monument of a transportation vehicle. The compartment 10 is preferably located close to a water supply and a power supply and is connected to the waterline 17 of the monument. Compartment 10 takes advantage of the presence of water and power supplies within the monument. Just a few minor adaptations are required to supply compartment 10 with water and power. This makes it easier to implement compartment 10. The monument is for example a galley, lavatory or stowage. An advantage of the invention is its seamless integration with existing vehicle (such as aircraft) infrastructure and leveraging the galley (for example) water system for its water supply. For example, the compartment can utilize a familiar connection mechanism connecting to that of a coffee maker, steam oven or faucet. Streamlining installation and minimizing retrofitting efforts. By tapping into the pre-existing infrastructure, the compartment and its system offer a cost-effective and practical solution for enhancing fire safety measures onboard vehicle such as aircraft.

[0046] Compartment 10 may further comprise a valve 22. Indeed, once the fire is extinguished, it is not necessary to further release water. The valve 22 is thus configured to supply the compartment 10 with water or to turn water off. The valve 22 may turn water off manually. Alternatively or in combination, the valve 22 may turn off after a period, and / or after a set volume of water has been used. Preferably, the valve 22 is outside the compartment 10 in order to have an easy and safe access to it.

[0047] Figure 2 illustrates a flowchart of a method to deal with fire. At step 24, the PED 11 is being charged. Compartment 10 is connected to both power (electricity) and water using standards. In the frame of an aircraft, it is ARINC size 1 standards. At step 26, a temperature and or a fire is detected. The specialized material 18 is utilized in that sense within the compartment 10, the material 18 exhibiting specific thermodynamic properties. This material is designed to undergo the transformation, such as melting, expanding or burning when exposed to temperature above the predetermined temperature threshold. Then, at step 28, water is provided. Water is released inside the inner space 12 until a manual closure of the water supply valve 22 and / or by the inclusion of an automatic valve system. This transformation serves as a trigger mechanism for releasing water (such as activating the sprinkler system), allowing it to deploy and commence fire suppression measures in response to elevated temperatures indicative of a potential fire hazard.

[0048] With the eradication of the need to have openings to get access to a possible fire, the entire compartment could be closed with a sufficient degree to contain enough water to extinguish the fire. The compartment can be at least partially watertight. In that manner the release of water at least partially fills the compartment 10 so as to drown and cool the loaded PEDs 1 1 , and extinguishing the fire. For example, The compartment 10 can be at least partially watertight over a certain height, the height being defined as a function of the number of PEDs and / or the size of the PEDs that can be charged in the compartment. Thus there is no need to rely on a small pool of water at the base of the PED to cool the batteries. Thanks to compartment 10, PEDs can be placed in such a way that the battery is not in / near this pool of water. Watertightness can be achieved in different ways. The doors 14 can be closed tightly. Once the doors 14 are closed and water released, water is confined to inner space 12. This contributes to extinguish the fire and to cool the PEDs 11 . It is also possible to consider that the doors 14 are of less than the height of the inner space 12, so that a lower part of the inner space 12 is designed as a retention tank. PEDs 11 are deposited in said tank during charging process and water release in the inner space fills that tank in a watertight manner so as to extinguish the fire and to cool the PEDs.

[0049] Figure 3 illustrates the compartment 10 according to the invention. Figure 3 shows the eradication of openings in front of the compartment 10 to get access to a fire. Since the compartment 10 ensures an automatic trigger of the water release, there is no need to have any smoke being readily observable by the crew and to facilitate manual application of water (for cooling / suppressing). Thus the compartment 10 does not necessitate multiple openings within the compartment structure. Thus, the absence of these openings suppresses any risk of allowing fire and debris to be expelled from the compartment 10. Nor a mesh structure is incorporated in front of any opening, intended to act as a barrier to prevent the egress of flames and debris. Also, the absence of openings prevents any explosive battery gases within the compartment 10 being expelled out of the compartment 10 and subsequently mixed with fresh air by the mesh structure. This mixing process that would inadvertently lead to the ignition of the gas-air mixture, resulting in the formation of flames shooting out from the openings, is prevented. The design's requirement for multiple openings for visual observation and manual intervention that conflicts with the need to prevent the expulsion of fire and debris is prevented. Also, the incorporation of mesh structures to address this conflict that inadvertently leads to the formation of a flammable gas-air mixture, resulting in the unintended consequence of flame generation, is also prevented.

[0050] Figure 4 illustrates another aspect of the compartment 10. In that aspect, compartment 10 can be removable. On figure 4, the compartment 10 can be removed according to arrow 31. Thus, a safe removal upon reaching vehicle destination (such as after landing) would improve the work environment of the vehicle crew and anyone involved. This also contribute to extinguish any fire. The compartment may comprise a connecting and disconnecting system, the system being configured to connect and disconnect the compartment from the waterline and from the power supply. The compartment 10 is easily removable using such a quick connect / disconnect system. For example, the compartment 10 may comprise one or more handles 32 (or pop-up handle(s)) to easily remove the entire compartment 10 (thus, designed as a station) eliminates the need to open the compartment 10 and deal with the PEDs 11 and battery fire up-close. When the vehicle reaches destination, such as after landing, the entire compartment 10 can safely be debarked and removed. The compartment 10 can be further enhanced with a fire suppression system to cool the fire before removing this. The compartment 10 eliminates the need to open the door(s) 14 and can be removed filled and / or cooled with water. This improves safety with low-tech solution and by using existing connectors and rails. Figure 4 shows a water connector 34 (to be connected to the connection 16), power connectors 36 (to be connected to the electrical inserts 13) and rails 38 (to guide the compartment 10).

[0051] Further, the compartment 10 may also comprise power cut-off means. For example, after a certain predetermined time, like 30 minutes, the power is cut-off. This prevents battery overheating. Alternatively or in combination, the power cut-off means are thermal power cut-off means. This reduces the risk of fire spreading and contributes to extinguish fire. Preferably, the power cut-off by the thermal means occurs at the same predetermined temperature threshold as the material transformation. This ensures that any action undertaken to extinguish the fire occurs at the same time. For example, thermal power cut-off means is a thermal switch or a temperature-activated switches: These switches turn off power to a device or circuit when the temperature rises above a set point. These are a simple mechanical devices that use for example a bimetallic element to open or close a circuit based on temperature changes. When the temperature rises above the predetermined temperature threshold, the bimetallic strip bends, breaking the circuit and cutting off power. The bimetallic strip is a strip made of two different metals bonded together, each with a different coefficient of thermal expansion. When the temperature increases, the metals expand at different rates, causing the strip to bend. This bending action can be used to open or close a circuit and cut off power. Both of these solutions are mechanical in nature and do not require any sophisticated electronics or programming. They are simple, reliable, and effective ways to cut power based on temperature. Alternatively, thermal means of power cut-off is a thermal fuse. This is a safety device that cuts off power when a certain temperature threshold is reached, preventing overheating. Further, thermal shutdown circuits can be used that are integrated circuits or devices designed to shut down power when a critical temperature is reached to prevent damage. Also, Programmable Logic Controllers (PLCs) can be used. These devices can be programmed to monitor temperature sensors and cut power to specific components or systems if predefined temperature thresholds are exceeded. Thermal Circuit Breakers are further examples. These devices are designed to trip and cut off power when the temperature of the circuit exceeds a certain limit, protecting the circuit from overheating. Temperature-Dependent Resistors (Thermistors) being components changing resistance with temperature can be used in circuits to control power based on temperature changes.

[0052] Figure 5 illustrates a detail of the compartment 10. This is an example of a thermal switch 39. The thermal switch 39 comprises terminal screws 40 for fixing, a mica insulation 42 surrounding contacts 44 such as platinum iridium contacts and springs 54, such as Inconel® springs. The thermal switch 39 further comprises a stainless steel body 46 and threads. A low expansion rod 48 within a high expansion tube 50 (such as Inconel® tube) is in contact with the springs 54 via a (sapphire®) insulator ball 52. A calibration screw 56 is also in contact with the springs 54. The (thermal) power cut-off means are low-tech solution, thus inexpensive to apply. No button is needed nor any intervention of the crew. It could be used as an additional safety feature on top or independently of any preceding components serving to extinguish the fire, such as the sprinklers.

[0053] The invention also relates to the monument comprising the compartment 10 as well as to a transportation vehicle with the monument. The vehicle may be an aircraft. The invention enhances the vehicle (such as aircraft) safety, with a particular focus on ensuring the safety of vehicle attendants. Compartment 10 can be implemented on all monuments in the aircraft or any mode of transport (like trains or boat) that offer PED charging and a water connection in the vicinity. Furthermore, The PED charging is implemented in a standard size electrical insert (oven or beverage maker) compartment, integration and connection to the water line being feasible with the compartment. In other words, the placement of the PED 11 charging infrastructure such as the compartment 10 within a standard sized monument such as a galley offers advantages in terms of integration and connectivity with the vehicle water supply system. This arrangement facilitates the seamless integration of the sprinkler like system (for example) with the existing infrastructure, enabling straightforward connection to the water line within the compartment. This integration ensures that the sprinkler system is supplied with the necessary water resources for effective fire suppression operations. The invention prevents a number of risks and issues that are partly due to the ‘personal’ nature of PEDs 11 leaving the user to control the quality of the device and connecting cables. The invention is more effective than using a water bottle to extinguish the fire. Using a water bottle may not suffice if the fire has spread or involves combustible materials beyond the bottle's capacity, risking reignition or spreading, heightening risks to passengers, crew, and the vehicle - what the invention prevents. Also, compartment 10 prevents risk of injury. Compartment 10 prevents vehicle crew such as flight attendants from facing injury risks when manually extinguishing fires, especially in high-stress situations involving large fires or hazardous materials, debris being expelled (what even increases the likelihood of slips, falls, or burns). Further, manual intervention may lead to response delays as the crew has to locate and prepare equipment, potentially allowing fires to escalate during critical moments. Unlike a manual intervention, compartment 10 prevents delays in response. Further, currently, placards and their texts are used to avoid having unattended charging PEDs 11 in areas such as galley area. However in practice this can be easily missed creating a potential risk when smoke, fire will execute, even if in cabin area the amount of passengers “ensure” a continues visual awareness in case of smoke, fire, whereas this is not the case in the galley, lavatory area. Compartment 10 avoids such situations. The automatic activation within compartment 10 does not require the vehicle attendants to visually or manually recognize and assess situations, retrieve water bottles, and apply them to fires, risking delays if attendants are occupied or unable to respond immediately. Lastly, relying on flight attendants for manual firefighting requires extensive training, adding to their workload and necessitating proficiency maintenance in firefighting techniques. The invention does not require any training requirements.

[0054] The present invention has been described in relation to the specific embodiments which have a value that is purely illustrative and should not be considered to be limiting. The skilled person will notice that the invention is not limited to the examples that are illustrated and / or described here above. For example, the (thermal) power cut-off means and the removable nature of the compartment can each be considered independently or in combination with the rest of the described features. The invention comprises each of the new technical characteristics described in the present document, and their combinations.
