01 – Press-fit – A modular table/seating furniture [Concept + prototype]

:: Design – A modular table/seating furniture

The design attempts to promote activities through movable and configurable furniture, where the objects have a positive feedback against the activity.

The activity of drinking is promoted here through the utilization of the empty beer bottles as a hinge of assembling 2 modules in forming different configurations of the furniture.

The more the drinking process goes, the more different furniture variations produced for the party to go on.

Seatingn design

A modular seat with 2 structural ribs and beam-like members to describe the sitting surface and the back.

Concept

3 tpyes of configurations can be achieved with the help of empty beer bottles.

Cut sheet

– 0.125 in radius dogbone (for avoiding imperfect press fit assembly for 90 degrees conditions due to the radius of drill bit)

– 0.0625 in radius corner fillet (for easier assembly)

Prototype

Fillet corner facilitates the insertion of tight-fit components.

:: Conclusions

Cutting

The original purpose of arranging several components in an angle is for maximizing the cutsheet with minimal material. However, during the milling, a comparable difference of cutting time was found between straight lines and lines in an angle. The balance between time spent on cutting diagonal lines and material being utilized has to be considered in the future.

Assembly

The filleted corners helped a lot on assembling the components into their corresponding slots.

Outcome

The seating surface turned out to be too flimsy. The depth of the beams have to be increased.
