FD4003-2

As my semester end exercise was assigned to learn about the Re-design process. I have to redesign the chair by taking dimensions of Nakashima's grass seated chair’s simply supported structure as a principle. While studying Nakashima chair I learned about one must respect the material, optimization, and precision of arrangement of every component of the chair. I choose to use MS rod because it will reflect the slenderness of components of Nakashima's chair. The main challenge with the metal rod is to create a light but strong furniture. I choose an 8 mm MS rod for the frame of a chair. I started to design the chair by taking geometry into consideration and then creating a structure out of it. I choose circle and trapezoid as my basic geometry which translates curves and negative spaces of Nakashima chair. By further resolving the structure, I designed a continuous geometry that gives triangular geometry for the whole structure. Triangular geometry gives structural strength to the chair. The chair is lightweight and can be easily carried to places. It has two operations i.e. bending and spot welding. It can be mass-produced also it is cost-effective.
