Design development report Assignment Example | Topics and Well Written Essays - 2500 words

Design development report - Assignment Example It guides design goals in order to meet the least significant detail or challenge up to the most important requirement for a more holistic result. Choices are guided by these principles for costs, economics, functionality, ergonomics, re-design methods or changes to meet goals such as elegant, modern, or stylish looks (Holm, 2006). Design approaches include user-centred which focuses on the requirement and limitations of the user, use-centred which is guided by the function of the artefact, the TIMTOWDI approach or â€Å"there is more than one way to do it† approach that follows multiple approaches, and keep it simple or KISS approach that minimises process and content without sacrificing aesthetics (Holm, 2006). Methods used in the design process may apply the following: Exploration of possibilities that encompass definition of problem and research. This may be used for existing facilities, products or services or even for creating new ones. This process also includes brainst orming where all stakeholders involved contribute to the goals and outcomes. Redefinition is the development and improvement of traditional specifications and guidelines to arrive at better options, solutions, and goals applicable n many fields of design. Management is the process of a continues approach to defining, exploring and creating new designs Prototyping is the production of possible products that improves traditional or existing designs Trend-spotting is the approach towards development of emerging or new products in order to achieve innovation (Getlein, 2008). Design in business has occupied a major role from a previously minor one. There was a time when industrialists hire designers to develop appearances of products or incorporate aesthetics on functional and already existing products. Today, even enterprises need to be designed in such a way as achieve a desired structure and external, visible properties as influenced by the environment and relationships (Giachetti, 20 10) Translation of the design brief into an outcome The design development process adopts fitting systems that meet the goals of the stakeholders. The design development involves defined scope of activities, understands the user and user needs, adopts ways to meet user needs, evaluates the solution, and finally implement the design. In a more streamlined approach, it involves: Identification of need Brief-building Concept generation Concept development Concept presentation Prototyping and testing Manufacturing (Presentation). Under the concept generation and development, solution centred approach is adopted where various factors meet on the centre. These include the various aspects of the design with consideration to target audience or market, final outcome of the materials, moral responsibility, the design, legislation, and raw materials. Each of these aspects encompass a wider concept that contributes to the whole: the audience are influenced to become aware of the brand and value of the product; the outcome needs to address functionality, safety, durability and longevity; under the moral responsibility is the firm’s commitment to its workers and the community of users;

RF and Microwaves - Essay Example In this paper, we are going to investigate the behavior of the antenna and make a proposal for a suitable solution to the circuit issue. Analysis in this experiment will be conducted using the Finite Difference Time Domain method (FDTD) method. This analysis will expose the variation of these characteristics with the height of the antenna. The Finite Difference Time Domain method (FDTD) method allows for direct calculation of the Maxwell’s curl equations on lattices in a given time domain. The choice of the rack server is very critical in the application of the Finite Difference Time Domain method (FDTD). It should have a size small enough to allow the realization of results that have high accuracy at frequencies that are very high and large enough to allow manageability of the available resources. The size of the cell is affected by the type of materials that are present in the rack server (Hiebel, 2010). The higher the amount of permittivity, the shorter the size of the wavelength that will be realized at a defined frequency and hence a smaller size of the cell will be required (Nurnberger & Volakis, 2000). This is defined by a rule that is smaller than a tenth of the size of the smallest wavelength and this can be defined by the size of the Finite Difference Time Domain method (FDTD) space and the maximum fr equency of interest. After the size of the cell has been selected, the time step that is maximum can be determined using the Courant condition of stability. Step times that are smaller are also permissible in this experiment and if they are used, they may result into results with an improved accuracy. Large time steps normally result into instability (Luebbers, 2004). In the use of the FDTD method, the field of incidence must be incident and must also be analytically specified. If the resonant geometries used are strong, the excitation of the finite- difference time-domain
