Patent ID: 8533985

Claim:
A method for attaching at least one first, smaller item having a least one planar surface to a second, larger item having at least one planar surface in a precise, yet repositionable manner, comprising the steps of: providing said larger item with a magnetic grid comprising a plurality of magnets; positioning said magnetic grid relative to said larger item, wherein magnetic poles of said magnets are evenly spaced on a Cartesian grid; and providing said smaller items, comprising any of unitary items and multi-unit items, for affixation to said larger item, each of said smaller items comprising at least two magnets to secure said planar surface of said smaller item against both translation and rotation to maintain a consistent alignment of said smaller item with said larger item, said at least two magnets separated from one another by a distance equal to said spacing of said magnets on said magnetic grid, said at least two magnets having an attractive force to said plurality of magnets of said larger item, wherein a 1-by-1 unit item covers a horizontal pair of magnets on said magnetic grid, wherein said unitary items comprises sizes of at least all of: a 1-by-1, a 1-by-2, and a 2-by-2 unit item; wherein, as a user moves said planar surface of a smaller item across said planar surface of said larger item, there is an affirming, snap-to-grid action as said smaller item attains one of a plurality of available aligned positions relative to said larger item.
