A system and method for constructing a composite structure using a multi-piece tool. The pieces are assembled, including making a connection, such as a mortise-and-tenon connection, between pieces using an adhesive mixed with an induction heatable material, such as iron filings having a unit size of between 5 microns and 600 microns, and an amount of between 5% and 50% by volume. Plies of a material are applied around the connection between the pieces, and the plies are cured to create the composite structure, which results in the pieces being trapped within the composite structure by the connection. The adhesive is exposed to electromagnetic induction from an electromagnetic induction coil which generates heat in the induction heatable material and thereby loosens the connection. The tool can then be disassembled by individually pulling at least some of the pieces from within the composite structure.

A method of assembling components of a vehicle is provided that includes locating a node (20) relative to an adjoining component (22), measuring at least one geometrical feature of the node or the adjoining component, 3D printing an assembly adjustment member (24) based on the measuring, and placing the assembly adjustment member proximate at least one of the node or the adjoining component. The assembly adjustment member is configured to allow relative movement between the node and the adjoining component for subsequent processing operations.

A wall-mountable accessory such as one which is intended for hanging in a bathroom. The wall-mountable accessory may be a robe hook, a towel bar, a grab bar, a toilet paper holder, a ledge, or the like. The wall-mountable accessory may include a solid body that is at least partially formed from a brittle material. The solid body may have a hole that extends to an opening in its outer surface. The wall-mountable accessory may also include a mounting assembly for mounting the solid body to a wall. The mounting assembly may include a standoff configured to be coupled to the wall and a fastening pin that is coupled to the standoff and has a portion that nests within the hole in the solid body. The mounting assembly may apply a compressive force onto the solid body to prevent fracture.

A method includes forming a cutout in a bamboo pole, the cutout having a non-uniform perimeter, and in which the perimeter increases towards a region of the bamboo pole where fibers of the pole are stronger than other regions of the bamboo pole.

A device for the shock-absorbing attachment of two elements to be assembled, the attachment device including: an inner part that is tubular along an attachment axis; an outer part that is tubular along the attachment axis, and hollow, the inner part being accommodated in the outer part such that the outer surface of the inner part is facing the inner surface of the outer part; an elastomer layer between the outer part and the inner part, the elastomer layer, when seen in section in a longitudinal plane including the attachment axis, including: to either side of the attachment axis, at least three so-called longitudinal portions, and at least two so-called transverse portions.

An arm-shaped structure includes a pipe-shaped main body and an attachment interface joined to at least one end of the main body and securable to another component. At least a portion of the main body and the attachment interface is formed by injection-molding resin containing a discontinuous reinforcement fiber. The main body and the attachment interface are joined to each other in a state where relative movement along a longitudinal axis of the main body and around the longitudinal axis is prevented by an uneven section formed by injection-molding.

A composite lid of a cylindrical container includes an outer metal lid having an integral top wall and sidewall and an inner plastic lid having a top wall and sidewall fitted inside the outer metal lid such that a free end of the sidewall of the inner plastic lid extends beyond a free end of the sidewall of the outer metal lid. The composite lid can be fitted on a base having an integral bottom wall and sidewall such that the sidewall of the inner plastic lid frictionally engages the sidewall of the base. The outer metal lid can be formed by stamping sheet metal, the inner plastic lid can be formed by molding a polymer material and the base can be formed by molding a polymer material. The outer metal lid can be adhesively bonded or mechanically fitted to the inner plastic lid.

Apparatus and methods for joining nodes to tubes with node to tube joints are presented herein. Joining techniques allow the connection of additively manufactured nodes to tubes. In an embodiment, at least one node may be joined to a tube and may be a part of a vehicle chassis. The node to tube joint connection incorporates adhesive bonding between the node to tube to realize the connection. Sealants may be used to provide sealed regions for adhesive injection, which are housed in sealing interfaces co-printed with the additively manufactured nodes. Additionally, seals may act as isolators and reduce galvanic corrosion.

An adhesive-distributing device for use in repairing or reconditioning a hollow profile includes an adapter body, in which is arranged at least one channel system made up of at least two channels connected to one another. At least one channel is connected to an injection opening for injecting adhesive into the channel system. Each channel is designed with at least one exit opening.

The present invention is applicable to the field of security and protection, and provides a combined fixing apparatus and an alarm device. The combined fixing apparatus includes: a first fixing part that can be fixed to an installation surface in a punching-free manner; and a second fixing part that can be fastened to an installation; wherein the first fixing part and the second fixing part are provided with detachable structures cooperating with each other and reliably connecting the first fixing part to the second fixing part respectively. The first fixing part and the second fixing part are detachably connected, which facilitates assembly and disassembly. Moreover, the first fixing part is fixed in a punching-free manner, which can avoid the damage to the installation surface and can reduce labor costs of installation, improving the working efficiency.
