Introduction of wasabi :D Hello everyone, we are from DCHE/FT/2A/01 Group 3.We named our team Wasabi and the reason being; we consider ourselves spicy and cool like its nature. We are a team of 4 and so without further a due, let us introduce ourselves. Member 1: Hey, I am Katrina. I like to learn new things and enjoy watching movies  😆  I'm excited to learn more stuffs from this module as it seems very cool and interesting. I hope to work well alongside with my teammates to achieve the best grade and learn from each other! Member 2: Hello readers, I am Ashwati. I love to read books and Im open to learning new things everyday. I'm a very friendly and bubbly person which makes me a person who laughs too often to almost everything! which pretty much annoys people. Woops😝I hope to enjoy my time while learning new and cool stuffs in this module. I also hope to work together with the team effectively and try my best to contribute as much as I can. Member 3: Hi, Jun lin here. At f...

Practical 4

Designing Game Machine Challenge For this practical session, we were tasked to make a game out of cardboard and use the basic joineries that we learnt from the previous practical in 2 hours. At the end of the practical, we were to present about our game, do voting amongst group for the game we think is the best and make a 30 seconds promotional video which will be shown to primary school students. Before going for the practical, we first discussed as a group about what game we were going to make. We decided to make a Plinko board game. We felt that it looked doable within the time limit and enjoyable for the kids to play hence it was chosen. After deciding on the game, we came up with the dimensions for the game.  Which are: length of top (not bottom)= 35 width of top=24 long rectangle side= 24 short rectangle side= 19 bottom length= 10 bottom width= 24 diameter of circle of cylinder= 5 diameter of circle cut for cylinder= 6 (all measurements are in cm) There were some dimensions t...

 Reflection: Today's lesson we learnt about product sketching and design specifications. Design sketching/drawing is essential in producing our chemical product as it enhances understanding, provide visual clues for possible further refinements and revisions of the product and improve communication with our clients. To prepare ourselves to draw our chemical product as part of our Activity 1, we were first tasked to draw lines, curves, circles and ellipses as it is the fundamental basics in sketching. Next, we were introduced to one point and two point perspectives where one point perspective has a single vanishing point whereas two point perspective has two vanishing points. The members perspectives drawing can be seen below: Katrina - 1-point perspective Katrina - 2-point perspective Ashwati - 1-point perspective Ashwati - 2-point perspective Jun Lin - 1-point perspective Jun Lin - 2-point perspective Xin Ni - 1-point perspective Xin Ni - 2-point perspective For Activity 1, Xin Ni...

  Reflection: Today's lesson covered operating principles & mechanism design for a product. Operating principles are basically how things work and all devices, equipment and apparatus are designed based on a working principle that are either mechanical, chemical, electrical or magnetism. We learnt some examples of operating principle that we see in our practical workshop such as the distillation that works on principle of volatility and devices in our daily lives such as the air-lift pump in a coffee maker that works on principle of buoyancy. With this, we were tasked to think about what operating principle our chemical product is based on. Our discussion are as shown:  Next, we learnt about the importance of mechanism in a product. Mechanism is important as it helps to enable and enhance the working principle the product is based on. Without mechanisms, the product is not functionable and hence are required. In the context of engineering, mechanism transforms forces and m...

  Pre-session preparation Corrugated fibreboard is a very  versatile  material  that has a wide range of uses   ranging from  material for packing to  containers.   Corrugated materials are pulps   made  from   softwood trees  that  have been   put   through  mechanical and chemical  pulping to break down the fibres. The corrugator is a continuous system designed to adhere sheets of paper that shapes bulk corrugated boards. It consists of 3    components: corrugated material in the center, outer and inner liners. During  manufacture, each side of the corrugated material is glued to the flat paper liner to   add rigidity and stability while fixing the flutes in position.  Additional fluting section   and liner can be added to help add strength and rigidity which can give different wall types (single/double/tri-wall). During recycle, the cardboard is separated from other mate...

 Reflection:  In today's lesson we got our keyring back when we designed it in our previous lesson in Fusion360 and saved it as a STL file. We learnt how it was 3D printed and converted into a file suitable to be 3D printed. First, the STL file would be converted into G-code file that would interpreted by the machine's firmware to be 3D printed. Afterwards, we delved into deeper how our keyring was made by introducing us to digital fabrication. Digital fabrication is important as society is getting increasingly digitalized and manufacturers are shifting towards advanced manufacturing technologies. Digital fabrication helps us to make our products quickly and is fully customizable to individuals needs. It is important for us to learn digital fabrication as it is growing rapidly in the chemical engineering field, for instance, the use of additive technology in oil & gas industry. The advantages of digital fabrication includes physical evaluation of design. performing functio...

 Reflection: In today's lesson, we started learning how to draw and design a 3D product using a CADD software, Fusion 360. Before attending tutorial, we first had to make our initials keyring with the help from the resources provided in blackboard. It was very frustrating and it took a lot of time as it was all new to us. It was difficult to navigate the tools required as the instructions provided were not matching with our updated fusion 360. The most confusing part for us was the offset as we couldn't make our design to be like the one shown in the instructions. Eventually, we managed to figure out and help one another whenever we were still stuck to a part. Some of us redid the whole steps again as our final product was not the same as the one shown in the instruction manual. Nonetheless, it was still fun trying to learn new things and experiment with the software while making our keyring. An example of our team's nametag is shown below: 1.      Jun Lin 2. Ashwati...

Reflection:  In the previous lesson, we have learnt and input our knowledge of materials for design for our chemical product. Today's lesson was designing for materials. We learnt how to change a design so that a particular material could be used. In addition, we learnt how the discovery of a new product leads to bringing new uses from the material attributes which could affect design changes and material research for design requirements and vice versa.  An example given to us was a hair dryer. A hair dryer consists of plastic cover with a bimetallic strip heating element. In order for the plastic to be made suitable as a material for the hair dryer, it uses a thermostat bimetallic strip so that the plastic won't melt under heat. This showed the change (bimetallic strip) in design for materials (plastic hair dryer).  From this example, we were tasked to do an activity where we had to find a material that can be a direct replacement of another in an existing product withou...
