Abstract

The objective of the present idea is to use wireless transmission of power- and data circuits in order to permit continuous printed wiring on the cabin linings and at the same time to be able to detach any individual lining for inspection/repair access.

Detachability of Cabin Linings with Printed Circuits by wireless power- and data transmission

Common Cabin walls are attached to the structure in terms of modular linings. For the side walls the linings are standardized to a dimension comprising two frame bays, i.e. normally including two window cut-outs.

The linings need to be able to be detached at any time in order to access electrical systems, and other equipment installed between lining and outer skin. Today this is

easily performed, and any lining can be readily removed, see Fig. 1.

The ease of this detachability lies in the strict separation of cabin lining and electrical systems. I.e. by taking down the lining, no systems are removed or

damaged.

There has been developed a widespread interest in supplying the cabin

linings with printed electrics, in order to save the large installation costs for the separate cable harnesses, and potentially to reduce some weight and gain some space. This includes the options of having printed circuits on the cabin lining, and/or on the structure and separate foils. These separate foils would then be

tightly attached to the back face of the cabin lining.

Nevertheless, the question of how to be able to continue wiring between two or

more linings, and at the same time be able to detach single linings is not yet solved.

The objective of the present idea is to use wireless transmission of power- and data circuits in order to permit continuous printed wiring on the cabin linings and at the

same time to be able to detach any individual lining for inspection/repair access.

Fig. 2 shows typical power- and data circuits that have been printed directly on the back face of a side wall lining, alternatively have been printed on a thin foil that is, in turn, attached to the back face of the lining.

Fig. 3 shows a part of a lining with printed circuits, with the edge visible that is to attach to the neighboring lining. The shown two power circuits and two data circuits

serve as minimal representation of a general case.

The signals of the power and the data circuits are to be transmitted to the

neighboring panel. For this purpose the circuits are printed until a distance close to the panel edge, but not fully to the edge. In a space next to the

edge, a hollow area is provided for the installation of a flat transmission unit, containing a power transmission circuit, as well as a data- transmission circuit. These are ideally separated, and exchangeable, and exist in standard

circuit solutions. The flat transmission unit can be installed into its place, and

contains flat printed transmission circuits, including induction coil.

The power and data transfer according to the present idea can e.g. be realized with near field antennas and...
