Abstract: A retractable roof construction can be manufactured in a factory and quickly deployed when assembling the house. The retractable roof can be made in parts and assembled into its compact formation whilst in the factory. This compact formation reduces space occupied in shipment, reducing the overall cost. When the compact formation roof is on a construction site, the roof can expand on both sides and be raised in the middle to provide an angle to protect against the rain. The expending process can be automated for reducing labor used in the construction. When compared to traditional roof construction, the retractable roof construction allows fast installation as well as reduced cost, both in shipping and labor.

Abstract: An adaptive support supports an expandable mobile house during and after expansion thereof. The adaptive support can be used on modular house to serve as support when deployed. The mechanism includes a static support beam and two support wheel that can be used interchangeably. The adaptive support can also be manufactured without the wheels when the house only needs static support. The mechanism can be retracted so it does not hinder the transportation of the mobile house. The adaptive support can adapt to an uneven terrain. A pressure sensor embedded in the support allows it to nullify the bumps on the ground during expansion of a mobile house using the wheels as support. A gyroscope sensor can be used to balance the house to be flat on sloped ground. If deployed on an artificial flat surface, the adapting system can be deactivated so it serves like a regular support beam.

Abstract: An expandable house that has a roof that can be adjusted to a set angle. The house can be expanded to more than three times the space as compared to its original size when it is extended. The unique design in the method of making an expandable house is that the roof is very flexible, so it can be angled whenever it is required. When the house is retracted, the roof is stored on the side of the house, so the height of the house can be reduced in its compact form. This house can expand in two opposite directions. The walls and floors of the expandable rooms are stored on the sides of the main structure where the house expands, behind the stored roof. The entire expanding and retracting processes are aided with electric motors, so no manual labor is required.

Abstract: A house structure is initially folded into a small box-like configuration for easy shipment and can expand both horizontally and vertically to form a traditional one-floor house-like configuration with inclined roofing. Parts of the front and rear walls are folded and stacked with ends of the main structure to save space in the width of the folded structure. Parts of the floor panels are vertically stacked with the sidewalls. These moveable floor parts are linked with the sidewalls and the middle floor panel through designed connection blocks. When the sidewalls are pushed outward, the floor panel will gradually slide and lay down. After setting up the sidewall and floor framework, the roof subassembly can be driven upward and rotate outward its set of wall wedge panels to encapsulate the opening area due to the inclined roof profile and offer support for the roof panels which are linked via connection blocks.

Abstract: A mechanism for hiding and storing a desk on the side wall of a house can allow the desk to be easily stored in the wall, so it does not take up any living space when it is not required. The transformation of the desk is different from the conventional flipping tray table, as the front side of the desk faces outward when the table is stored in the wall. The desk can include additional functionalities that can be used both while the desk is stowed on the wall and when deployed as a table. An example of such functionality includes a digital clock and a file cabinet. The desk can be secured in each state by the sliding pin that can be inserted into the wall.
