Abstract: In a packaging cushion device, a base member has a base wall, and first and second sidewalls respectively perpendicular to two adjacent edges of the base wall. The base wall and first and second sidewalls define a receiving portion. A modular component has a base panel, two adjacent first and second side panels perpendicular to the base panel, a first projection extending from the first and second side panels, and a second projection extending from the base panel and the second panel. The first and second projections are matchable with and connectable to the receiving portion to form two interchangeable configurations of different heights, thereby satisfying the need of packing a computer housing in either folded or unfolded configuration, and saving packing materials.

Abstract: A single-piece packaging plate foldable to form boxes having different sizes is provided for a product having a variable size. The packaging plate has an elongated plate portion, two side plate portions and two wing portions. The elongated plate portion has a plurality of parallel and spaced-apart preformed fold lines. The side plate portions extend outward from two sides of the elongated portion, and have fold lines at the junctures thereof. The two wing portions can be torn or cut out optionally. Each wing portion has a main wing extending from two sides of an area between sixth and seventh fold lines of the elongated plate portion. The packaging plate is foldable along the fold lines to form a unit body-packaging box or a system-packaging box.

Abstract: A housing for an electronic device is adapted for disposition of a motherboard, a plurality of data access devices, and a plurality of cables. The housing includes a housing body and a partition plate. The housing body defines a receiving space. The partition plate is disposed in the housing body, and divides the receiving space into a first receiving compartment adapted for receiving the motherboard, and a second receiving compartment adapted for receiving the data access devices. The partition plate has a side edge cooperating with the housing body to define a wire sorting space that is in spatial communication with the first and second receiving compartments. The wire sorting space allows the cables that are connected electrically between the motherboard and the data access devices to pass therethrough. Consequently, convenience during assembly or disassembly by users or repair personnel is improved, and easier organization of the cables/wires is possible.
