Tidis-B (Transport of Individuals with Disabilities into Bed) is an assistive device designed to move a person from a wheelchair to a conventional bed, as well as from a conventional bed to a wheelchair. The device is intended for use in homes and is able to transport a person who weights up to 300 lbs. In addition, the device requires minimal physical assistance by caretakers, which can help prevent back injuries. The device is designed so that the person being transported is comfortable and safe. The Tidis-B supports individuals who use wheelchairs and lack the ability to transport themselves from the wheelchair to the bed. This device requires the assistance of a second individual who could help operate the device.
The device is operated by a conveyor system made of a gear motor, a conveyor belt, 15 conveyor rollers, a power supply, and a 12-volt battery. The purpose of the gear motor is to provide a specified amount of torque capable of rotating the conveyor belt and rollers while the individual is seated on it. The ideal and actual designs perform the same task, although they are not completely similar. The ideal design is the electromechanical design that would be operated with an electric motor and a hydraulic lift table, and the actual design or the prototype is operated mechanically. The materials used in the prototype are carbon steel and aluminum alloy 6061.
