The brief was to design a rocking chair for children made out of plastic. The technology behind it is plastic injection moulding. The aim is to be creative and learn the possibilities and constrains of this technology.

The rocking toy can be made in several variations. One constrain is that the shape must be kept the same for all options. Variations can be added by changing the moulding method.
Constrains to consider: slightly conical shape so that the part can be removed from the matrix, resistance structure, area of joining. The yellow lines represent the axes where the pieces join. The grey area represents where the forces are applied.
The rocking chair is made out of two different parts. It has one color option. The two parts are joined on 2 axes. This is the cheapest option of all four.
The rocking chair is made out of four different parts. The two-point casting offer different colors options. When mixing the colors, slight defects can appear. Another piece is applied to hide the merging of the colors. The two parts are joined on 2 axes.
The rocking chair is made out of six different parts. It has three color options. The colors are applied with a higher precision.
The six parts are joined on 3 axes thus making the structure stronger .

Aesthetic extensions offer a bigger area to make the pieces join even stronger. The six parts are joined on 3 axes
