An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors preferably additively printed on the substrate film; a light source provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception; an optically transmissive plastic layer produced upon the first side of the substrate film, said plastic layer at least laterally surrounding, the light source, the substrate film at least having a similar or lower refractive index therewith; and a reflector design comprising at least one material layer, said reflector design being configured to reflect, the light emitted by the light source and incident upon the reflector design.

Optically functional multilayer structure and related method of manufacture

An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors on the substrate film; and a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception via associated outcoupling areas, wherein for each light source of the plurality of light sources there is optically transmissive plastic layer, produced upon the first side of the substrate film, said plastic layer at least laterally surrounding the light source, the substrate film at least having a similar or lower refractive index therewith; and reflector design including at least one material layer, provided at least upon the light source and configured to reflect the light emitted by the light source and incident upon the reflective layer towards the plastic layer.

A method for manufacturing an electromechanical structure, including producing conductors on a flat film; estimating a strain a plurality of locations of the flat film will undergo during formation thereof into a three-dimensional film; attaching electronic elements on the flat film at selected locations of the plurality of locations of the flat film, wherein the estimated strain of the selected locations of the plurality of locations is less than the estimated strain in other locations of the plurality of locations; forming the flat film into the three-dimensional film; and injection molding material on the three-dimensional film.

Method for manufacturing an electromechanical structure and an arrangement for carrying out the method

A system for manufacturing an electromechanical structure includes first, second, and third entities. The first entity produces conductors on a planar, flat film. The second entity attaches electronic elements at locations on the film in relation to a three-dimensional shape of the film. The electronic elements include a number of surface mount technology components. The locations of the electronic elements are selected to omit substantial deformation during subsequent forming of the film into the three-dimensional shape. The third entity forms the film into the three-dimensional shape when the electronic elements are supported on the film. The third entity includes one or more machines that are continuously roll-fed, automatically in-precut-pieces-fed, computer numerical control, thermoforming, vacuum former, pressure forming, or blow molding. The first, second, and third entities are arranged relative to one another to manufacture the electromechanical structure.

System for manufacturing an electromechanical structure

A method for manufacturing an electromechanical structure, includes producing conductors and/or graphics on a substantially flat film, attaching electronic elements on the said film in relation to the desired three-dimensional shape of the film, forming the said film housing the electronic elements into a substantially three-dimensional shape, and using the substantially three-dimensional film as an insert in an injection molding process by molding substantially on said film, wherein a preferred layer of material is attached on the surface of the film. A corresponding arrangement for carrying out the method is also presented.
