Week 5

Design for Materials (DFM) Design for materials is the opposite of MFD. Instead of choosing the best material for the product, DFM is changing a design so that a particular material can be used. DFM can be used when the material used is expensive and we want to make sure we do not waste it. We can then use DFM to create a design which can make full use of the material, so that we will not waste any of it. Another example when DFM is used is when the material is not commonly used. We can then used DFM to make a product using the material. We can then cut down the used of commonly use materials with another material which is not commonly used. For our assignment, we had come up with a material and use it to enhance the functionality of an existing product through some changed in the design. We had chose the material "Alcantara" which is mostly used for making car seats' cover. We had thought to use Alcantara to make phone covers, or any product which requires a good grip. T

Computer-Aided Drafting and Design (CADD) CADD is the use of software to draw and design physical components or to layout processes. With CADD, shapes and lines can be drawn easily and quickly, content can be easily copied, edited, saved and shared. CADD software also allows accurate calculation of dimensions and more advanced software can even accurately estimate the kinds and amount of materials used of the length of manufacturing time, which facilitates budget planning. It is hence beneficial for a product design to know how to use a CADD software. We had learnt to use Fusion360 to model shapes or designs. We can also use a 3D Printer to print our design we had made in Fusion360. In class, we had learn how to make a simple keyring and learn how to hasten drawing process through the use of sketch constraints.  Some of the common tools meaning used are: Offset  - Copy selected sketch geometry a specified distance away from the original geometry. Extrude - To make a 2 Dimension shape

In week 6, we were introduced to Product Life Cycle and Cradle to Cradle.  Product Life Cycle There are 6 stages in the product life cycle; Raw materials, Manufacturing, Packaging, Distribution, Use and Disposal.  Stage 1: Raw materials or extractions. This stage refers to the extraction of raw materials required to produce the product.  Stage 2: Manufacturing and production. This is the stage where the raw materials collected are made into the product. Stage 3: Packaging. Once the product has been made, some of which has sent overseas either by plane or ship. The products will be packed into boxes and wrapped in plastic films. If the product is fragile. newspapers or bubble wraps are also included in the box. Stage 4: Distribution. Once the product has been packed, it is now ready to be sent overseas.  Stage 5: Use. This is the period in which the product made is being used. Stage 6: Disposal. After the product cannot be used anymore, we have to dispose the product. Ways of disposal i
