Chair design

 

 

R shell is formed by two curve surfaces, lean against one another.

Taking the shell construction engineering method as reference, find how two surface suppor­t each other, strike balance between the point, line, the virtual and entity surface. Then construct the shape of the chair.

 

One of the surface is constructed with multi-lines . With the lines, form of virtual surface taking visual into another level. While on the entity surface, a notch and a bulged up rib corresponds. The mesh crossed around the whole chair, a multi-level overlapping shadow is formed under the light.

For applications like the ingenious mechanics engineering and techniques in building (St. Mary's Cathedral,Tokyo), the outer lines are neat, and the light and shadow are just perfect and fascinating.

I think to myself: is there an opportunity that this method can be used on to product design?

Focusing on the advantage of the mechanics and techniques of Hyperbolic Paraboloid shell, I used it on chair design in which ergonomic is necessary and also demonstrate the beauty of the structure.

 

 

 

Shell construction method let the outer building be made by very thin shell, but still has strong support and protection. Under appropriate circumstances of technology applications, even 4 to 10 cm thick wall will be able to a large building by thin shell.

Taking St. Mary's Cathedral, Tokyo, a representative thin shell structure, as a starting point. Analyze the force on the two curvature shell surface and construct a surface of another form. Deconstructing the relationship between the surface and the line, re-arrange and composed. Finding how two surface support each other, strike balance between the point, line, the virtual and entity surface. Then construct the shape of the chair.
