4: What is a sketch model? Advantages of these?

Answer 2

1: A drawing that has it’s face flat and then projects to the rear of it.

2: Provides essential info to stakeholders – more realistic view of product. Iterative design process complies with this.

3: Dimensions, Details of Components, Materials, Assembly Instructions. Normal 2D Orthographic

4: Simple models, low cost materials used – create accurate models of the drawing

Question 3

1: Why would an exploded drawing be beneficial to the designer and stakeholder?

2: How does a flowchart help the designer? What are the different stages within a flowchart?

3: What is a schematic diagram and it’s purpose?

Answer 3

1: Exploded drawings are usually drawn in isometric projection – they show key details to a certain section of the idea – providing more information.

2: Flowcharts help us to understand simple processes and how to overcome possible problems. Made up of; Terminal/diamond (start/end), Process/rectangle (an activity), Input or Output/ rounded box, Decision/Diamond.

3: Show arrangement of components in electrical and mechanical systems.

Question 4

1: When approaching a design where could you get information from?

Answer 4

1:

• Focus Groups, Questionnaires, surveys, first hand research observations
• Product analysis – similar products finding problems
• Nature themes – biomimicry
• Size of the potential item – will it function in the area
• Data from magazines, internet, government agencies
• Anthropometric data
• All of these areas can help the designer to avoid design fixation.

Question 5

1: What is the importance of User Centred Design?

2: What does the term ‘systems thinking’ mean?

3: What is the importance of effective collaboration?

Answer 5

1: UCD is based on the understanding of users, the tasks they do and the environments that they live in. In UCD we use focus groups, usability tests, interviews, questions to help find information.

2: A product is not a product it is a whole service. A camera for example is not a product it is a service that offers memories to its users. Smartphones are a good example of these now.

3: Effective collaboration between designers, developers, users and stakeholders, can be difference between success and failures
