 Practical 5 (Egg Drop Challenge) This blog will mainly be about practical 5. The objective of the practical is to design and make a device that enables a raw quail egg to survive a fall from a height of 2 metres without any cracks.  Design: We took inspiration from a project online about egg drop challenge which utilise one of the strongest shape which is triangle. Insert making it a shape of triangles, we decided to change the shape into squares. First design Second design In the end, we decided to go with the second design as it would require less material which will reduce the time needed to print. Since the design looks like a porcupine, we decided to name our design project porcupine. We decided to make 3 parts which includes the main body, the long sticks to fasten the two main body together and short sticks that will be attached on all four sides of the body.  This was the first design of the main body: Long stick fasteners: Short sticks:  However, after p...

 Week 11: Material For Design For the past term, my team and I have gone through 3 stages of chemical product design which are mainly needs identification, ideation and selection. Now we are at the 4th stage which is prototyping and product development. In order to start, first we have to choose the materials for our product. In this blog, I will be showing what I have learn about material for design. There are 3 steps in material selection process which are mainly: Define material requirement for design (Which is about function, constrains and objectives of the product) Select and evaluate candidate materials (COWs) Choose the most economical material For CA2, we were tasked to select material for a single use water bottle (disposable) that does minimum environmental harm Figure 1: Bottle o water Step 1: Define material requirement for design Table 1: Material Requirements Step 2: Select and evaluate candidate material (COWs) For the bottle material, we did research on the various...
