The Design Process Flashcards
what is technology
It is the use of knowledge, skills, values and resources to meet people’s needs and wants.
what must be taken into consideration to develop practical solutions to problems.
social and environmental factors
what subjects are available in grade 10
Civil, Mechanical, Electrical Technology and Engineering Graphics or Design.
who does technology in their job
anyone who makes and designs a product as a part of their job.
what is a design process
a set of steps we use when we plan how to make a product.
what do the steps in your design process help you to do
- change / solve a problem
- change your design to satisfy the need that was originally identified
what are the five steps in a design process and describe them
1 - Investigate
in this stage you’ll find + use info. you’ll identify the need / problem, find out who you are making the product for and who will use it. you’ll also collect info about existing products that might help to solve the problem.
2 - Design
when you start to design your product, you begin by writing short statement that describes the need / problem more. this is called design brief. you’ll also write design specifications, these provide details about the product you’re going to design, such as who it’s for, what will it look like, what will it do, materials that’ll be used and safety aspects. you’ll also need to think about any constraints / limitations that apply. these can include cost and availability of materials and how much time you have to make it.
In design stage you’ll make initial idea sketches or possible ideas to meet needs of design brief. you’ll also identify and select materials needed. at this stage, you should choose your best design idea and develop it further.
3 - Make
in this stage you’ll make working drawings, sketches and technical drawings that show product’s specifications. you’ll develop plan to make product. plan includes amount of time and the tools, equipment and materials list required to make the product. your plan include manufacturing sequence.
use correct tools and materials you include in your plan to make products. making products might involve measuring, marking, cutting, shaping, forming, joining and finishing different materials with accuracy. remember to work safely.
4 - Evaluate
once product has been made, it needs to be evaluated. in this stage you’ll evaluate design stages and the quality of the finished product. includes checking how well design meets design brief and design specifications. we use evaluation criteria to evaluate the design process and product. evaluation criteria are set of questions about how well design process was carried out, and how well product meets design specifications.
at this stage recommendations can be made for improvements to the product.
5 - Communicate
in this stage, you’ll present design solutions by means of notes and drawings. your presentation should show different ways you gathered info, sketches with measurements and your reasons for using specific design ideas.
meaning : design brief, design specifications, constraints and evaluation criteria
design brief - a short statement that describes a need / problem
design specifications - details about product, such as its function and appearance
constraints - things that limit your choices
evaluation criteria - set of questions about the design process and product
what must we make sure when we design a product
that it’s suitable for its use / purpose
what are the questions that you must ask about your product to check that its suites its purpose before you start finding a solutions to the problem. describe these questions
- who is it for:
product must be suitable for the gender, age and social background of the person using it. - what is it for:
product must be the solution to the design problem - will it do the job:
product must be workable as this is main factor user will consider before purchasing your product. - is it cost effective:
could be similar products to yours available, but yours must be cheaper - is it safe:
safety is an essential aspect of design process. the final product mustn’t put customer in danger. E.g sharp edges and naked electrical wiring must be avoided. - is it easy to use (ergonomics):
products used in workplace must be comfortable and safe. ergonomics is concerned with working out accurate measurements for equipment that’ll be used in workplace in order to to increase productivity. e.g if you’re designing office chair, you need to work out most comfortable seating height. - does it look good (aesthetics):
product must appeal to buyers. must look like it will do the job and must be aesthetically pleasing. Aesthetics means the attractive qualities or beauty of a product. consumer won’t buy product if it is unattractive - will it affect society:
product shouldn’t be danger to society. any effects it has on society should be positive. - will it affect the environment:
when creating product you must consider effects of manufacturing process on environment. you must consider measures that reduce harmful effects on environment. E.g. you could try use materials that are recycled or can be recycled.
