About Us

Our Company

FourierIdea, Design, Engineering and Art, shortly called as Fourier Idea, is a company established in 2006 to develop new engineering and scientific ideas with artistic designs for physical puzzles and scientific toys.

The company was formed shortly after the patent was filed for the Sliding Shell Mechanism. Since it’s formation, several other inventions applicable to toys and puzzles have been developed by the owners.

In 2007, we started researches on clean energy and efficiency in generation of solar and wind energy. These studies has ended to invention of a new solar tracker and new ideas of combinations of the solar and wind generators that can significantly increase the efficiency in clean power generation.

Our company is now active in both fields of Toys production and Engineering services.


We are a group of professional engineers with academic background and artistic enthusiasm, experienced in engineering design, construction, and manufacturing.

Our vision

Our vision is to create some novelties that can make life more desirable, to produce toys and puzzles that are both educational and entertaining for any age, and find Energy solutions to keep environment cleaner for the next generations.

We are open to any comment and proposal. If you have a new idea that we may be able to help you in developing and bringing that to reality, please contact us.
