The KiteGen Research C-shaped semi-rigid Power Wing (an extract of the topic below) is built with small elements hinged together by flexible joints.
“The result, as can be seen from the picture below has the dimensions of the wing of a large airliner but is lightweight and semi-rigid. The wing is formed by 9 ashlars hinged together by flexible joints, thanks to which it can easily change configuration in order to vary the wing lift factor.”

A similar method could perhaps be studied for other rigid wing designs in order to benefit from simpler manufacture and transport, as well as greater lightness, with an appropriate bridle.
