Bar Table Design

Bar Design

The design concept of the bar is to create one which is aesthetically pleasing yet able to withstand a heavy amount of load and economically inexpensive to build. For the design of my bar, the aesthetic aspect of it is inspired by the lines that are produced during the 'folding' process.

Hence, I was able to sketch some of my initial ideas for the design of the bar as shown below.

During the making of the design, I first made a box in Grasshopper and then insert a component in order to give a random set of points in the box before drawing out lines in order to make a design concept just like my initial ideas. 

After making the design of the structure for the bar, the program Karamba is used in the scripting process to provide an optimal result. After seeing the results, iterations of the design is made until the perfect result for the design came out.

For my final design, it is shown in the load test that the design can withstand a maximum load of 190 kg and from the deformation test, it is seen that when the bar will collapse on one side first when the maximum load is exceeded.

The bar structure is going to be made up of wood beams, a glass table top, and 3D printed nodes. From my design, a total of 23 nodes is needed in assembling the bar.

Below, is the rendered version of the bar. The material used for the beam structure is glossy varnished oak as it is classified as a strong and durable hardwood which is relatively inexpensive for its quality. It also gives a beautiful appearance to the structure and is adaptable to its surroundings. Besides that, it is one of the types of wood that has low maintenance. As for the perspex glass, it will be clear yet tinted blue glass just for a better aesthetic touch.

For the manufacturing process, the nodes as it is written before will be 3D printed whereas the table top will have to go through CNC milling. 

The above pictures are how the whole bar will be assembled

Week 3 Experiment

The Tower

In order to build up the highest tower which can withstand the blow test, we decided to design a tower using playing cards and paper clips. The design chosen by the group is a triangulated tower with a base that surrounds the main tower to give it some structural support so that when blown, it won't easily collapse. 

The triangulated base supports as a base to secure the cards onto the ground firmly. The cards are then joined together in a triangular shape by paper clips. The reason why a triangular shape is chosen is so that more cards can be used to stack up making the tower taller.

Resulting Video:

When the tower was blown gently, the tower only swayed a little. But as soon as a huge blow was given, the tower collapse.

Week 2 Experiment

Advanced Structural Bridge Experiment

Experiment 1

For experiment 1, we decided to make a design as shown above so that the 'bridge' can hold a huge amount of load when applied. Besides that, it is also quite appealing aesthetic wise.

During the making Process

Resulting video:

The outcome is successful as it can withstand a few bag of papers as well as 2 people.

Experiment 2

The design chosen for the 2nd experiment is as shown above because we believe that with that kind of design, the 'bridge' can stay balance even if there is a heavy load applied.

Resulting Video:

The outcome of the experiment is a failure. Even though it didn't collapse, but as more load is added, the design started tilting to one side.

Experiment 3

The design for the paper 'bridge' is similar to that of last week's paper design except this time, instead of a spring, the insides of the paper is rolled paper stuffed in as many as possible, with the hope that it can withstand the heavy load.

Resulting video:

The outcome is quite a success. The paper got a little bit of compression but it is not totally squished.

Week 1 Experiment

Making Structural Bridge

Experiment 1

Materials:

• Skewers
• Hot glue gun
• Tray

Final Design:

The design we decide on is this 'span bridge'. The reason being for the force of the load to act on the centre and give a balance so that the 'bridge' won't collapse. 

Resulting Video:

The outcome is a failure because the design is not long enough for the sides of the design to sit properly on the tables.

Experiment 2

Materials:

• Skewers
• Elastic Band
• Tray

Final Design:

This design is used because we believe that this type of 'truss bridge' would hold up the load firmly.

Testing Process:

Structure with only 1 bag of paper

Structure wih 2 bag of paper

Structure collapse

Resulting Video:

In reality, the design could not withstand the load because the rubber joints did not join the skewers firmly, causing the bridge to collapse to one side.

 Experiment 3

Materials:

• Paper
• Tray

Final Design:

The paper design we made is wrapped up by more than 20 papers. It is design as shown above because we believe that by adding a few springs inside the rolled paper, it will give the papers a more firm 'bridge'.

Testing Process:

Structure with 2 bag of paper

Structure with 3 bag of paper

Structure with 4 bag of paper

Due to the structure not collapsing, a force 

is given in order for it to collapse

Resulting Video:

At the end, the design succeed the expoeriment.
