Apparatuses, methods, and systems are disclosed for attaching structures. One system includes: a device having a first structure attached to a second structure; a first polymer coupled to the first structure, wherein the first polymer has a first temperature profile and a first shape; and a second polymer coupled to the second structure. The second polymer has a second temperature profile and a second shape. The second shape interlocks the first shape. The first polymer and the second polymer secure the first structure to the second structure in response to the first polymer and the second polymer being in a first temperature range. The first polymer and the second polymer release the first structure from the second structure in response to the first polymer and the second polymer being in a second temperature range different from the first temperature range.

A method of manufacturing a display device includes bending a first film member of a processing object such that a part of one side of the first film member surrounds a part of an outer side of a bending area of a second film member of the processing object while the first film member is laminated on the second film member.

An apparatus to aid in applying a screen protector to the display of a mobile electronic device such as a smartphone. The apparatus in some embodiments is a wedge or ramp that is placed between the display and the screen protector to support a portion of the screen protector above the display. The user may withdraw or move the wedge or ramp and tip the screen protector onto the display. The wedge or ramp may have a plurality of profiles or surfaces on which the screen protector rides as the wedge is moved, the profiles or slope of the surface aiding in controlling the rate at which the screen protector descends onto the display. The apparatus may also include a frame to go about the perimeter of the mobile device to aid in positioning the screen protector. The frame may include alignment aids and absorbent material about the perimeter of the mobile device.

An apparatus for applying screen protection to electronic gadgets is disclosed wherein a quick locking mechanism secures the electronic gadget in a fixed place with a plurality of paddings provided on both sides of the phone. A slider is provided to adjust to different sizes of the phone in order to quickly fit any available device and a cavity allows for back cameras or any portion of the phone protruding to sink in and allow the phone to always be at level for application of the screen protection. The cavity in a base plate of the apparatus is exchangeable to fit for any phone model with different protruding cameras and portions. A process is also disclosed wherein the phone is secured to the apparatus by the lock lever and release mechanism, a transfer tape is applied onto the screen protector; then backing paper is removed. A blank is aligned over the smartphone or tablet being secured to the apparatus, then the tape is swiped over to adhere to the protector and finally tape is removed.

Some embodiments of a compression mold for forming a rib-and-sheet part includes a mold cavity and a mold insert. A sheet is placed in the mold cavity, and the mold insert is placed on the sheet. A preform assemblage is placed in a gap that is formed between the mold insert and the wall of the mold cavity. A mold core is biased above the preform assemblage, prior to molding operations, via a compression spring.

A manufacturing method of a housing includes the following steps: a preformed housing is provided. The preformed housing includes a body and a sidewall connected to the edge of the body, and a decoration film disposed on the body and the sidewall. A portion of the sidewall is exposed from the decoration film. The body includes a first surface. The sidewall includes a second surface. The second surface extends from the first surface. The first surface and the second surface are non-coplanar. A decoration layer is formed on the exposed portion of the sidewall by a surface processing treatment.

The present invention provides a blocking piece covering the sound hole of a loudspeaker and an assembling method thereof, and a loudspeaker module. The blocking piece covering the sound hole of the loudspeaker module is arranged at a position where the sound hole is located on the case of the loudspeaker module and covers the sound hole. The blocking piece is made of a nonmetallic flexible net. The nonmetallic net-shaped blocking piece and the case are formed integrally by injection moulding. The loudspeaker module and the blocking piece covering the sound hole thereof in the present invention have advantages of good acoustic performance, high reliability, high space utilization rate and high production efficiency. The assembling method for the blocking piece covering the sound hole of the loudspeaker module further makes the assembling of the blocking piece convenient for operation, and improves the assembling efficiency and assembling quality.

A machine can include a base including a first cradle. The first cradle can include a device slot being configured to securely hold a first electronic device. The machine also can include an alignment piece hingedly attached to the base at a hinge. The alignment piece can include an alignment base configured to engage with an alignment mechanism of an overlay applicator. The machine additionally can include a pulling piece movably attached to the base. The pulling piece can be configured to remove an adhesive release liner of the overlay applicator to expose an adhesive agent of an overlay of the overlay applicator when the alignment piece is rotated relative to the base around the hinge from a first alignment piece position to a second alignment piece position. Other embodiments are described.

A method for manufacturing a middle frame assembly for a mobile phone manufactures a middle frame by sheet metal machining processes, forms an antenna on the middle frame by injection-molding processes, and forms an outer frame as a coating on an edge of the middle frame by the other injection-molding processes. The disclosure further provides a middle frame assembly and an electronic device. The method is simple and low in processing cost.

A tool for assisting in affixing a screen protector to a display of an electronic device is provided. The tool includes first and second segments slidably attached to define an interior of the tool. The first segment has a first side, a second side attached to the first side by a first corner alignment feature, and a third side attached to the second side by a second corner alignment feature. The second segment similarly includes a first side, a second side, and a third side. The first and second corner alignment features of the first segment and the first and second corner alignment features of the second segment are configured to center the electronic device in the interior of the tool when the first segment is slid relative to the second segment.
