Implementations described and claimed herein provide systems and methods for delivering a customizable feedback stimulus. In one implementation, a custom feedback device comprises a shell housing having a first shell and a second shell. The shell housing opening extends between an outer surface of the first shell and an outer surface of the second shell. A plurality of protrusions extends between the first shell and the second shell, and at least one receiving area is defined by the plurality of protrusions between the first shell and the second shell. The receiving area is adapted to house a customized portion.

A toy building assembly for providing means of creating a variety of structures includes a plurality of elements. Each element comprises a plurality of first slats, which has a plurality of second slats engaged thereto. The first slats and the second slats are layered in a 1:2 ratio thereof to define two sets of second slats. Each set of second slats extends from a respective opposed end of the plurality of first slats to define a respective terminal connector. The sets of second slats have a gap positioned therebetween to define a medial connector. A respective terminal connector of one of the elements is selectively insertable into at least one of a terminal connector and a medial connector of at least one other of the elements. The elements of the plurality of elements thus are interconnectable to create a wide variety of structures.

A building block includes at least one of a plug portion and a socket portion. The plug portion has two cantilevered tongues deflectable toward each other. Each cantilevered tongue includes a first engaging portion. The socket portion defines a chamber and has two second engaging portions. The plug portion and the socket portion are configured in such a way that the plug portion of one building block is insertable into the chamber of the socket portion of another building block, and the two cantilevered tongues of the building block deflect toward each other after insertion of the plug portion of the building block into the chamber of the socket portion of the other building block, which allows the first engaging portions of the building block to be engaged with the second engaging portions of the other building block, thereby connecting the two building blocks together.

The invention relates to construction toys, is light-weight, low in material content, highly manufacturable, and requires less space for storage and transportation. The present building block for a construction set is made of molded paper pulp in tire form of a parallelepiped and consists of two separate hollow-bodied elements, the first of which comprises a face having at least four protuberances, and side walls, and the second of which has at least one protuberance; the two block elements are capable of being joined together by fitting the second element between the side walls of the first element, and one of said block elements comprises at least one limiting well.

An insert-and-twist building block structure includes a connection bar and a connection terminal unit. The connection bar has an end from which a combination projection section extends and has a conic shape. The combination projection section has an external circumferential surface formed with a bead ring including multiple raised beads intermittently arranged in a ring configuration. The connection terminal unit includes a connection terminal having an end inward recessed to form a combination cavity in a conic shape. The combination cavity has an internal circumferential surface formed with a groove ring including multiple recessed grooves intermittently arranged in a ring configuration. The recessed grooves each a middle portion forming a deep trough section and two ends each forming a shallow trough section, and a depth is decreased from the deep trough section toward the shallow trough sections.

A modular construction kit includes modular construction blocks, each includes at least one interface face. The interface face includes a recess, a plurality of connection apertures disposed proximate to the edge of the recess, and a circular interface receptacle disposed in the center of the recess. The kit also includes modular construction connectors, each includes two opposite sides, wherein each side including a body, a plurality of connection studs extending outwardly from the body, and a protrusion extending outwardly from the body. Some modular construction blocks include predetermined functions. A modular system block includes at least a processor, storage, and wireless communication.

A building block includes at least one of a plug portion and a socket portion. The plug portion has two cantilevered tongues deflectable toward each other. Each cantilevered tongue includes a first engaging portion. The socket portion defines a chamber and has two second engaging portions. The plug portion and the socket portion are configured in such a way that the plug portion of one building block is insertable into the chamber of the socket portion of another building block, and the two cantilevered tongues of the building block deflect toward each other after insertion of the plug portion of the building block into the chamber of the socket portion of the other building block, which allows the first engaging portions of the building block to be engaged with the second engaging portions of the other building block, thereby connecting the two building blocks together.

A panel and a system for use in building a lightweight structure are provided. The panel, made of a film or a sheet capable of being curved or bent with fingers, includes a body in a geometric shape circumscribed by straight or curved edges, and at least one joint formation along the edge for panel connection. The joint formation has tabs separated by at least one gap. Each tab expands bilaterally and proximally from the body at its base, and each gap is positioned along the edge so as to accept the base of the tab. The joint formations along the edges of varied curvatures are alignedly, hingedly, and detachably interlocked with each other by twisting the panels with fingers to individually hook the tab at the gap. The panels are assembled into geometric structures having flat or curved faces.

A building block system includes one or more building blocks and one or more wheels, each building block including a first elongate portion extending in a longitudinal direction, a second elongate portion extending in that longitudinal direction, an intermediate portion connecting the first elongate portion with the said second elongate portion at a middle position thereof, a first end portion extending in a transverse direction, perpendicular to that longitudinal direction, from the first elongate portion, at a side thereof opposite to the intermediate portion, and at a middle position thereof. A second end portion extends in that transverse direction, perpendicular to the longitudinal direction, from the second elongate portion, at a side opposite to the intermediate portion, and at a middle position thereof. It thus includes six protrusions and two voids, each void defined between an end of the first elongate portion and an end of the second elongate portion.
