Rogier Waaijer's view on the design process of the Lonc Seaser.
Side view sketch of the basic forms, starting point being a lounge sit angle with tilted arm rests.
Left: Side view sketch of an alternative with a smaller basis and a hole underneath the arm rest Side view sketch presenting an alternative of a smaller basis and an opening below the arm rest. Right: A similar sketch with a more organic kind of form
First computer CAD model, combining the (main)basic form with ergonomic dimensions
CAD model in which the sketch ideas are translated into a 3D form
Mockup, constructed out of layers of Styrofoam and based upon the dimensions of the CAD model
Ergonomic tests using the mockup
Finetuning the (main)form as well as the ergonomic dimensions of the CAD model
Real size CNC computer milled prototype. The prototype is milled out of solid MDF wood out of 3D computer data of the finalized CAD model.
Coating process of the MDF prototype
Prototype with color coating
Visualization of the desired parting lines of the production mould. Hence the best position for placement of these lines can be evaluated upon the prototype
Finalised CAD model, ready for tooling and production
Transparent view of the CAD model to show the cavity in the base in which extra weight can be added
Technical drawing with specifications for tooling and production
CNC computer milling of the mould out of solid aluminum. In this way the highest mould quality can be reached resulting in a product with a high level of finishing
The production mould consists of 4 different parts. 4 piece production mould ready for use
The first out of tool, which is the very first product out of the production mould. After this the mould can be fine tuned and a texture and coating can be added to the mould.
