;;Task 1;Task 1 Look at the following pictures of prototyping and complete the form below.;x;Text;1. Prototype A prototype is an original type, form, or instance of something serving as a typical example, basis, or standard for other things of the same category. ;2. Duct tape Duct tape is a vinyl, fabric-reinforced, multipurpose pressure sensitive tape with a soft and tacky pressure sensitive adhesive. It is genrally silver or black in color but many other colors and transparent tapes have recently become available. Its strength, low cost, and remarkable versatility make it a household staple for temporary repairs and general-purpose use. ;3. Baling wire Baling wire, otherwise known as “farm wire” or “soft wire”, is primarily used in an agricultural setting for everything from mending fences to manually binding square bales of hay, straw, or cut grass. Baling wire is commonly used in many non-agricultural applications, usually in an informal, make-do (代用的) manner. It is frequently referred to as one of the basic repair materials. ;Task 1 Look at the following chart. Name THREE phases of product design that can be completed more easily by means of CAD.;Task 2 How does prototyping fit into the design process? Brainstorm at least THREE advantages of Rapid Prototyping.;Prototyping Prototyping is the design verification phase of product development used to demonstrate or prove aspects of a design. Prototyping is simply taking the design from the virtual and imaginary realm to the physical world. ; There are many levels of prototypes. Some are simple duct-tape and baling wire to visualize how something might work; others are highly polished but fragile representations for show and tell; still others are functional representations that work. The kind of prototype used should fit the needs of the project—especially since there is often a significant cost involved.; Typical prototyping methods include clay (or
