Abstract: A pneumatic active sealing wall can create a seal between a movable wall and another part of a structure, such as a recreational vehicle, mobile home or the like. The pneumatic active sealing wall design allows the wall to expand from two sides, and, by expanding the wall parts into the side walls, gaps will be eliminated. The sealing wall can be used, for example, to create a seamless wall for folding mechanisms. Since such folding mechanisms do not allow lamination connection, the stretchable design of the pneumatic active sealing wall can solve the problems associated with sealing such movable walls.

Abstract: A storage mechanism for houses and expandable houses allows items to be stored in a space close to the ceiling so the storage space will not reduce the available floor space in the house. The storage will only reduce the height of the ceiling by a small amount, which does not affect most people. When activated, the system can automatically move the stored item to the room on the side and make them accessible to the user. The design aims to allow the users to store many items on top of their head to save spaces. It essentially eliminates the need of an additional storage room in smaller houses. It also allows multifunctional room when the storage system have some furniture like a TV and a mattress installed in it. It can help smoothly transform a living room to a bedroom and vice versa.

Abstract: A utility closet can combine part of the bedroom furniture, such as a table or desk and nightstand, with a wardrobe.

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: A removable window includes a frame on the wall that allows the window to be mounted firmly without any gaps between the frame and the window. The frame on the wall can include a rotating locking mechanism that helps secure the removable modules on the wall and prevents the window to be inadvertently knocked down under any unwanted situations. The window can be fitted on the wall by pushing the removable window module into the frame, and the window module can be locked on the wall. When the window module is removed, several different wall modules can be mounted onto the frame. Such wall modules can not only serve as enclosed walls, but can also provide additional functionalities. This effectively allows users to freely move their windows around the house and switch their windows with other walls to change the overall window layout.

Abstract: An apparatus provides for the flexible adjustment of the position of the windows, as well as for the ability to change the light transmission area of a single window, without wasting too much space. The apparatus can transform windows into completely opaque walls, for example, to achieve partial or complete light blockage by moving several wall panels hidden inside the sill up and down to specified positions. A set of push plates inside the sill can be used to displace the wall panels horizontally and a set of lifting plates on the window frame can be used to move the wall panels up and down along a track. At the same time, after selecting the specified position, the corresponding position can have a stick to push the wall panel into the specified position and tighten and fix the wall panel in the desired position.
