Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to marking products and, more particularly, marking fabric carrying cases for electronic devices.

2. Description of the Related Art

Embroidery or ink has been used for marking fabric items for many years. For example, it is common for garments to be marked with an owner's initials using embroider or ink. Conventionally, such marking is done with an ink printing or stamping process or with an embroidery process. Although embroidery or conventional ink printing and stamping is useful for many situations, such techniques can be inadequate for marking other items. For example, conventional marking techniques may not be able to offer sufficient accuracy and precision. Thus, there is a need for improved marking techniques.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

The invention pertains to techniques or processes for providing markings on fabric articles. In one embodiment, the articles may be fabric carrying cases for electronic devices. For example, a fabric carrying case for a particular electronic may include a fabric base layer and a plurality of thick films coupled to the fabric base layer, wherein the plurality of thick films may comprise a top thick film and an underlying thick film. Regions of the top thick film may be selectively etched through, for selectively exposing the underlying thick film. The selectively etched regions may be arranged for marking of textual or graphical indicia on the fabric carrying case for the portable electronic device.

Exemplary embodiments of the invention are discussed below with reference to FIGS. 1A-9. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments.

FIGS. 1A-1B show various views of a fabric carrying case 1000 for a portable electronic device 1001, wherein the fabric carrying case is marked according to one embodiment. FIG. 1A shows a top view, wherein the portable electronic device (not shown in FIG. 1A) is disposed within the fabric carrying case 1000.

As particularly shown in perspective view in FIG. 1B, the fabric carrying case may comprise a main body portion 1002 having an interior space 1003 to hold the electronic device 1001, and an opening 1004 into the interior space 1003 through which the electronic device 1001 can be moved. Examples of portable electronic devices include, but are not limited to, mobile telephones (e.g., cell phones), Personal Digital Assistants (PDAs), portable media players, remote controllers, pointing devices (e.g., computer mouse), game controllers, tablet computers, laptop computers, etc.

As discussed in greater detail subsequently herein, the main body portion may comprise a fabric base layer and a plurality of thick films coupled to the fabric base layer. The plurality of thick films may comprise a top thick film and an underlying thick film. Selectively etched regions 1006 of the top thick film may be etched through the top thick film, for exposing the underlying thick film through the selectively etched regions of the top thick film. The selectively etched regions 1006 may be arranged for marking of textual or graphical indicia 1006 on the fabric carrying case 1000 for the portable electronic device 1001.

FIG. 2 is a diagram of a marking state machine 200 according to one embodiment. The marking state machine 200 reflects three (3) basic states associated with marking a fabric article. The marking state machine 200 includes an initial fabric state 202. At the initial fabric state 202, a fabric base layer can be obtained or produced. For example, a knit backing of fibers may be used. The fibers may comprise nylon fibers.

Next, the marking state machine 200 can transition to a state 204 wherein a plurality of thick films may be coupled to the fabric base layer. The fabric base layer may provide strength and/or support for the plurality of thick films. The plurality of thick films may comprise differently colored thick films of substantially the same material. For example, plurality of thick films may comprise differently colored thick films of polyurethane. The plurality of thick films may comprise a top thick film and an underlying thick film.

Next, the marking state machine 200 can transition to a marking state 206. At the marking state 206, marking can be produced on the article to be marked. In particular, a fabric carrying case for a portable electronic device can be marked.

The marking can be provided with high resolution. As will be discussed in greater detail subsequently herein, the article may be marked by employing laser ablation to selectively etch through regions of the top thick film. The underlying thick film may be selectively exposed through selectively etched regions of the top thick film.

The marking can be provided with high contrast. The plurality of thick films may comprise highly contrasting, differently colored thick films. Accordingly, high contrast marking may be provided by the high contrast of the underlying thick film being selectively exposed through selectively etched regions of the top thick film.

FIG. 3 is a cross sectional view of an article 300 having marking alterations according to one embodiment. Fabric base layer 302 of the article 300 is depicted in the figures using stippling. An adhesive layer 304 may adherently couple a plurality of thick films 306, 308 to the fabric base layer 302. A suitable adhesive may be used for the adhesive layer 304, such as the FINE brand UA series adhesive, or in particular the FINE UA-5900 adhesive. Such adhesives may be available from FINE Chemicals Co., Ltd. having a business address at 68, Haejangseo-ro, Rokjik-jin, Ojung-gu, Soju City, Gangso, China.

In the figures, adhesive layer 304 is depicted using cross hatching. An underlying thick film 306 is depicted using right to left hatching. A top thick film 308 is depicted using left to right hatching. As shown in FIG. 3, the plurality of thick films 306 may be arranged so that a major surface of the top thick film 308 directly contacts a major surface of the underlying thick film 306.

The top thick film 308 may have a thickness dimension of less than approximately fifty microns. The top thick film may have a thickness dimension of about twenty microns. The top thick film may have a thickness dimension of about ten microns. Hence, in one embodiment, the top thickness film may have a thickness within the range of 10-50 microns. However, the thickness is dependent on materials, laser, and laser processing conditions. Similarly, the underlying layer 306 may have a thickness dimension of about twenty microns. The adhesive layer 304 may have a thickness dimension of about thirty microns. However, the thickness of the underlying layer 306 and the adhesive layer 304 can vary with application. For example, the thickness of the underlying layer 306 may be substantially greater than twenty microns, and the adhesive layer 304 may be substantially greater than thirty microns. The base fabric layer may have substantial thickness, which may provide strength and/or support for the plurality of thick films 306, 308.

Each of the plurality of thick films 306, 308 may comprise substantially the same material. For example, each of the plurality of thick films 306, 308 may comprise a plastic. Each of the plurality of thick films 306, 308 may comprise a reaction polymer, or more particularly may comprise a polyurethane. Each of the plurality of thick films 306, 308 may be non-fibrous.

The plurality of thick films 306, 308 may comprise differently colored thick films of substantially the same material. As mentioned previously herein, the differently color thick films may be highly contrasting, so as to provide for high contrast marking of the article 300. A visual appearance of the underlying thick film 306 may be substantially lighter, or may be substantially darker than a visual appearance of the top thick film 308.

As shown in FIG. 3 regions 310 may be selectively etched through the top thick film 308, for selectively exposing the underlying thick film 306 through the selectively etched regions 310 of the top thick film 308. As will be discussed in greater detail subsequently herein, the selectively etched regions 310 of the top thick film 308 may be laser ablated. The selectively etched regions 310 may be arranged for marking of textual or graphical indicia on the article 300. The selectively etched regions 310 may be arranged in a halftone pattern.

Various fabric articles may be marked. The marking is, in one embodiment, particularly well-suited for applying text and/or graphics to a fabric carrying case for a portable electronic device. As noted previously, examples of such portable electronic devices may be mobile telephones (e.g., cell phones), Personal Digital Assistants (PDAs), portable media players, remote controllers, pointing devices (e.g., computer mouse), game controllers, tablet computers, laptop computers, etc.

FIG. 4A is a flow diagram of a marking process 400A according to one embodiment. The marking processes can be performed on a fabric article that is to be marked, and in particular, can be performed on a fabric carrying case that is to be marked. The marking process 400A may be suitable, for example, for applying text or graphics to a fabric carrying case for a portable electronic device. The marking can be provided such that it is visible to users of the fabric carrying case. However, the marking can be placed in various different positions, surfaces or structures of the fabric carrying case.

In accordance with the marking process 400A shown in FIG. 4A, the process may begin with obtaining 402A a fabric base layer for the article. After the fabric base layer has been obtained 402A, an adhesive layer may be applied 404A to the fabric base layer, and may be cured. Accordingly, the adhesive layer may be adherently coupled to the fabric base layer.

After the adhesive layer has been applied and cured, an underlying thick film, for example, an underlying thick film of colored polyurethane, may be applied 406A to the adhesive layer using thick film techniques, and may be cured. After the underlying thick film has been applied and cured, a top thick film, for example, a top thick film of differently colored polyurethane, may be applied 408A to the underlying thick film using thick film techniques, and may be cured. Accordingly, the plurality of differently colored thick films may be adherently coupled to the adhesive layer.

Next a laser beam may be directed 410A to the top thick film. Using laser ablation, regions may be selectively etched 412A through the top thick film, for selectively exposing the underlying thick film through the selectively etched regions of the top thick film. Laser ablating may employ a visible laser, or may employ an ultraviolet laser. Following the block 412A of selectively etching the top thick film, the marking process 400A shown in FIG. 4A can end.

FIG. 4B is another flow diagram of another marking process according to another embodiment. Similar to the marking process 400A and shown in FIG. 4A as just discussed, the marking processes 400B shown in FIG. 4B can be performed on a fabric article that is to be marked, and in particular, can be performed on a fabric carrying case that is to be marked. The marking process 400B may likewise be suitable, for example, for applying text or graphics to a fabric carrying case for a portable electronic device. The marking can be provided such that it is visible to users of the fabric carrying case. However, the marking can be placed in various different positions, surfaces or structures of the fabric carrying case.

In accordance with the marking process 400B shown in FIG. 4B, the process may begin with obtaining 402B a fabric base layer for the article. After the fabric base layer has been obtained 402B, an adhesive layer may be applied 404B to the fabric base layer, and may be cured. Accordingly, the adhesive layer may be adherently coupled to the fabric base layer.

After the adhesive layer has been applied and cured, an underlying polymer-based film, for example, an underlying thick film of colored polyurethane, may be applied 406B to the adhesive layer using thick film techniques, and may be cured. After the underlying thick film has been applied and cured, a top polymer-based film, for example, a top polymer-based film of differently colored polyurethane, may be applied 408B to the underlying polymer-based film using silk screening, or other thick film techniques, and may be cured. Accordingly, the plurality of differently colored polymer-based films may be adherently coupled to the adhesive layer.

Next a laser beam may be directed 410B to the top polymer-based film. Using laser ablation, regions may be selectively etched 412B through the top polymer-based film, for selectively exposing the underlying polymer-based film through the selectively etched regions of the top polymer-based film. Laser ablating may employ a visible laser, or may employ an ultraviolet laser. Following the block 412B of selectively etching the top polymer-based film, the marking process 400B shown in FIG. 4B can end.

FIGS. 5A-5D are cross sectional diagrams illustrating marking according to one embodiment. Fabric base layer 502 for the article to be marked is shown in FIG. 5A. In the figures, fabric base layer 502 is shown using stippling.

As shown in FIG. 5B, an adhesive layer 504 may be applied to the fabric base layer 502, and may be cured. Accordingly, the adhesive layer 504 may be adherently coupled to the fabric base layer 502. In the figures adhesive layer 504 is shown using cross hatching.

After the adhesive layer 504 has been applied and cured, a plurality of differently colored thick films 506, 508 may be adherently coupled to the adhesive layer 504, as shown in FIG. 5C. An underlying thick film 506, for example, an underlying thick film 506 of colored polyurethane, may be applied to the adhesive layer 504, and may be cured. After the underlying thick film has been applied and cured, a top thick film 508, for example, a top thick film 508 of differently colored polyurethane, may be applied to the underlying thick film 506, and may be cured.

Using laser ablation as shown in FIG. 5D, regions 510 may be selectively etched through the top thick film 508, for selectively exposing the underlying thick film 506 through the selectively etched regions 510 of the top thick film 506. The selectively etched regions 510 may be formed by suitably selected optical energy 507 produced by a suitably selected and operated laser 509. Laser 509 may be a visible laser 509, or may be an ultraviolet laser 509.

The selectively etched regions 510, in aggregation, provide marking of the fabric article 500. The laser 507 may include a galvanometer mirror or other arrangement for raster scanning a spot of the optical energy over the top thick film 508, so as to form selectively etched regions 510 into a rasterized depiction of marking indicia. Suitable pitch between raster scan lines of the scanning spot for the marking may be selected. For example, pitch between raster scan lines may be about forty microns, and scan speed may be about four hundred millimeters per second.

The top thick film 508 may be raster scanned more than once. In particular, in a case where the top thick film 508 may be substantially thicker than approximately twenty microns, additional raster scanning may provide more complete etching of material of such thicker top thick film 508. Whereas the top thick film 508 may be scanned a first time at a first scan speed using scan lines having a first orientation, the top thick film 508 may be scanned a second time at a second scan speed using scan lines having a second orientation. The second scan speed may faster than the first scan speed. The second orientation may be angled at forty-five degrees relative to the first orientation. The second orientation may be angled at ninety degrees relative to the first orientation.

FIG. 6 is a table illustrating exemplary laser operation parameters according to one embodiment. In particular, the table of FIG. 6 shows examples of various suitable laser models which may be used for marking the fabric article. The PowerLine 20E SHG is a Q-switched, frequency doubled Nd:YAG laser (532 nm green-visible wavelength) from Rofin-Sinar Laser GmbH in Bergkirchen. From the same manufacturer, The PowerLine 20E THG is a Q-switched, frequency tripled Nd:YAG laser (355 nm ultraviolet wavelength) It should be understood that the table of FIG. 6 shows approximate exemplary laser operating parameters, and that various other laser operating parameters may be selected to provide the fluence of the optical energy that ablates the top thick film, so as to etch selectively through the top thick film, for selectively exposing the underlying thick film through the selectively etched regions of the top thick film.

FIG. 7 is a diagram of a magnified top view representative of a lightness halftone pattern 713 for marking according to one embodiment. A visual appearance of the underlying thick film may be substantially lighter than a visual appearance of the top thick film 708. FIG. 7 uses left to right hatching to depict the lightness halftone pattern 713, which selectively exposes the lighter visual appearance of the underlying thick film through the selectively etched regions 713 of the top thick film 708. The top thick film 708 is depicted in FIG. 7 using stippling. Size of the selectively etched regions 713 of the top thick film 708, as well as spaced apart arrangement of the selectively etched regions 713 of the top thick film 708 in the lightness halftone pattern 713 may be selected so as to provide a desired lightness halftoning appearance.

FIG. 8 is a diagram of a magnified top view representative of a darkness halftone pattern for marking according to another embodiment. A visual appearance of the underlying thick film may be substantially darker than a visual appearance of the top thick film 808. FIG. 8 uses cross hatching to depict the darkness halftone pattern 813, which selectively exposes the darker visual appearance of the underlying thick film through the selectively etched regions 813 of the top thick film 808. The top thick film 808 is depicted in FIG. 8 using stippling. Size of the selectively etched regions 813 of the top thick film 808, as well as spaced apart arrangement of the selectively etched regions 813 of the top thick film 808 in the darkness halftone pattern 813 may be selected so as to provide a desired darkness halftoning appearance.

FIG. 9 is a top view of yet another embodiment of the marked fabric case 9000, along with a detail magnified view to show the halftone pattern 9015. As shown in FIG. 9 selectively etched regions 9006 may be arranged for marking of textual or graphical indicia 9006 on main body 9002 of the fabric carrying case 9000. The halftone pattern 9015 may be a lightness halftone pattern as discussed previously herein with reference to FIG. 7, or may be a darkness halftone pattern as discussed previously herein with reference to FIG. 8. Whereas FIGS. 7 and 8 were each greatly simplified to show just two etched dots of the lightness and darkness halftone patterns in magnified view, FIG. 9 shows a somewhat larger number of the etched dots of halftone pattern 9015 in magnified view.

Size of the selectively etched regions of the top thick film, as well as spaced apart arrangement of the selectively etched regions of the top thick film in the halftone pattern 9015 may be selected so as to provide a desired halftoning appearance. For example size of each of the selectively etch regions may be etched dots sized with a diameter of approximately fifty microns or approximately sixty-five microns. Spaced apart arrangement of the selectively etched regions may be an arrangement of the etched dots spaced apart by approximately one-hundred-and-twenty microns.

The marking processes described herein are, for example, suitable for applying text or graphics to a fabric article. The marking processes are, in one embodiment, particularly well-suited for applying text and/or graphics to a fabric carrying case for a portable electronic device. Examples of such portable electronic devices may be mobile telephones (e.g., cell phones), Personal Digital Assistants (PDAs), portable media players, remote controllers, pointing devices (e.g., computer mouse), game controllers, tablet computers, laptop computers, etc.

The portable electronic device can further be a hand-held electronic device. The term hand-held generally means that the electronic device has a form factor that is small enough to be comfortably held in one hand. A hand-held electronic device may be directed at one-handed operation or two-handed operation. In one-handed operation, a single hand is used to both support the device as well as to perform operations with the user interface during use. In two-handed operation, one hand is used to support the device while the other hand performs operations with a user interface during use or alternatively both hands support the device as well as perform operations during use. In some cases, the hand-held electronic device is sized for placement into a pocket of the user. By being pocket-sized, the user does not have to directly carry the device and therefore the device can be taken almost anywhere the user travels (e.g., the user is not limited by carrying a large, bulky and often heavy device).

The various aspects, features, embodiments or implementations of the invention described above can be used alone or in various combinations.

Different aspects, embodiments or implementations may, but need not, yield one or more of the following advantages. One advantage of the invention is that durable, high precision markings can be provided to fabric articles. As an example, the markings may be provided on a fabric carrying case that not only have high resolution and durability but also provide a high quality appearance. Another advantage is that the marking techniques are effective for surfaces that are flat or curved.

The many features and advantages of the present invention are apparent from the written description. Further, since numerous modifications and changes will readily occur to those skilled in the art, the invention should not be limited to the exact construction and operation as illustrated and described. Hence, all suitable modifications and equivalents may be resorted to as falling within the scope of the invention.
