Q1) (i) What is Product Design Specification? • The Product Design Specification (PDS ) is an essential document that is compiled during the early Engineering Design Process, specifically in the Problem Definition stage. The information listed in the PDS includes the crucial parameters, product specification and requirements for the product that you are designing and NOT the ACTUAL parameters of the finished product. • As PDS is created in the early stage of the design process, it is constantly changing as the project progresses due to additional information that has been learned throughout the project • Aside from listing important parameters of a product being designed, PDS also includes the different issues that a product may encounter …show more content…

What are the Various Phases of a Design Specification? Explain in detail with your own examples • Marketing- This is the first among the 7 Phases of a Design Specification. Marketing is defined as a societal process, therefore in essence, it involves the interaction between the designers/manufacturers and the clients/customers. For a product/service to be well received by the target market, the designers should gather information relating to the wants and needs of the consumers. This can be in a form of a survey to determine the type of product/service that is most appealing to the consumer. Once information has been gathered and analyzed, the designers can respond accordingly to develop a product based on consumer demand. The last stages of the Marketing phase includes advertising, distribution and finally the selling of the product to the target market. • Design Problem- In this phase the design problem of a product is identified. This can be through a customer feedback in the case of products that already exist. The design problem phase provides an opportunity to identify a problem and will eventually lead to finding an idea to solve that problem. The design problem phase also enables us to further improve and develop the design of an already existing …show more content…

The size specified is in inches or in the “Imperial Unit”. If the product is to be exported then the size specification should also include the “SI” or metric equivalent. The drill is required to have 2 speed configurations. However the customer has not specified the desired rpm they want for the product. No information has been given as to what type of material the drill can be subjected to other than it can be used for soft and hard drilling. The customer has indicated that the drill should be able to “Operate continuously for long periods of time”. Different materials to be drilled have different effects on the drilling machine. Softer materials offer less resistance to the machine and therefore it can operate far longer compared when drilling a hard material. The type of the material to be drilled and the actual time the drill should be capable of drilling that material should be indicated. Hammer action and the eccentricity requirements can be achieved by using high quality gears and bearings. Incorporating this type of components in the design can affect the cost of manufacturing and will lead to an increase in the maximum price of the
