Method for designing detachable objects using magnetic holding force

Abstract

Provided is a method for designing a detachable object to an item by setting design objectives including a magnetic holding force objective needed to hold the detachable object to the item. A set of magnetic pieces are selected based on the holding magnetic force objective. An outer magnetic piece is fabricated onto the detachable object and an inner magnetic piece is fabricated and positioned within the item. The selection of the magnetic set and/or the position of the outer and inner magnetic pieces are modified until the design objectives are met.

1 . A method of designing a detachable object for an item, the method comprising:
 setting one or more design objectives for designing a detachable object for an item using magnetic force wherein one objective is a holding magnetic force objective;   selecting a magnetic set based on the determined holding magnetic force, the magnetic set including an outer magnetic piece and an inner magnetic piece;   determining a process of attaching the outer magnetic piece to the detachable object;   determining a design and position of the inner magnetic piece in the item;   fabricating the outer magnetic piece onto the detachable object and positioning the inner magnetic piece in the item;   if the one or more design objectives are not met, modifying the selection of the magnetic set and/or position of the inner magnetic piece and iterating determining the process of attaching the outer magnetic piece onto the detachable object, determining the design and position of the inner magnetic piece in the item, fabricating the outer magnetic piece onto the item and positioning the inner magnetic piece until the one or more design objectives are met.

       3 . The method of  claim 2  wherein the neodymium magnets have a rating of N42, N50, or higher. 
   
   
       4 . The method of  claim 1  wherein the item is a shoe and the detachable object is shoe jewelry. 
   
   
       5 . The method of  claim 4  wherein the outer magnetic piece is a disk neodymium magnet. 
   
   
       6 . The method of  claim 4  wherein the outer magnetic piece is a square, ring, strip, rectangular, or cylindrical neodymium magnet. 
   
   
       7 . The method of  claim 1  wherein the inner magnetic piece is a disc or block neodymium magnet securely positioned between two layers of materials of the shoe. 
   
   
       7 . The method of  claim 1  wherein the inner magnetic piece is disc or plate neodymium magnet varying in thickness from 1/16 inch thickness to 1/32 inch thickness or less. 
   
   
       8 . The method of  claim 1  wherein the inner magnetic piece is a flexible sheet of neodymium magnet. 
   
   
       9 . The method of  claim 1  wherein the inner magnetic piece is ferrite magnet or a flexible sheet of ferrite material. 
   
   
       10 . The method of  claim 1  wherein the fabricating the outer magnetic piece onto the detachable object comprises:
 creating a cavity in the detachable object wherein the cavity is slightly larger than the outer magnetic piece; and   attaching the outer magnetic piece to the detachable object using the cavity.   
   
   
       11 . The method of  claim 10  wherein the outer magnetic piece is attached to the detachable object using metal adhesive. 
   
   
       12 . The method of  claim 1  wherein the outer magnetic piece comprises two or more neodymium magnets attached to the detachable object. 
   
   
       13 . The method of  claim 1  wherein the detachable object is jewelry made of gold, silver, platinum, or any combination of the foregoing. 
   
   
       14 . The method of  claim 1  wherein the detachable object is jewelry made of precious metals or jewelry made of precious metals decorated with diamond and/or gemstones. 
   
   
       15 . The method of  claim 1  wherein the item is a shoe, handbag, purse, hat, cap, jacket, boot, suitcase, briefcase, or belt. 
   
   
       18 . The method of  claim 1  wherein the outer magnetic piece is painted with a color substantially close to the color of the surrounding portions of the detachable object. 
   
   
       17 . The method of  claim 1  wherein modifying the selection of the magnetic set and/or position of the inner magnetic piece includes changing the thickness of the inner magnetic piece or changing the inner magnetic piece to a sheet magnet or flexible magnet. 
   
   
       18 . An apparatus fabricated to keep a detachable object attached to an item under normal intended use, the system comprising:
 an item having a normal intended use;   a detachable object configured to be attached to the item using a set of magnetic pieces, the set of magnetic pieces comprising:
 an outer magnetic piece coupled to the detachable object; and 
 an inner magnetic piece positioned within the item; 
   wherein the outer magnetic piece and the inner magnetic piece are configured to generate a holding magnetic force sufficient to keep the detachable object attached to the item under normal intended use.   
   
   
       19 . The apparatus of  claim 18  wherein the holding magnetic force is provided by neodymium magnets, samarium cobalt magnets, or electro magnets. 
   
   
       20 . The apparatus of  claim 18  wherein the neodymium magnets have a rating of N42, N50, or higher. 
   
   
       21 . The apparatus of  claim 18  wherein the item is a shoe and the detachable object is shoe jewelry. 
   
   
       22 . The apparatus of  claim 18  wherein the outer magnetic piece is a disk neodymium magnet or block neodymium magnet.
