Design and Manufacture of a Second Generation Switch-operated Window Wall

Abstract

A new system of horizontal window blinds that operates by means of electrostatic induction, called the powerblind, was developed at North Carolina State University. The blinds can be opened and closed with a simple switch. An evaluation of the first-generation system was conducted to determine the features that needed improvement before a second-generation model could be constructed.

The problems inherent to the previous powerblind model were resolved after redesigning several parts. Eight new, fully operational powerblind units were assembled and installed in a boardroom of the Talley Student Center at North Carolina State University in July 2006. They replaced the defective first-generation units previously located in the boardroom. A set of instructions for all the assembly and manufacturing processes was also created to facilitate the construction of additional second-generation windows.

With the improvements made to the design and to the manufacturing process, it was concluded that commercial production would be possible at this stage of the project. The powerblind windows remain cost effective, when compared to the combination of standard window blinds and insulated glass. The ability to quickly and easily control the amount of light entering a room makes these windows desirable for many applications.
