1.28 Design Communication

Question 1

Design reports

Answer 1

an industrial design team’s project record for future reference

Executive summary
- Concise overview of the project, the resulting design and its effectiveness
Introduction
- Design problem context
- Details of client and possible customers
- Alternative ideas and the selection process used to choose the final
design
Conclusion
- Description of the selected design
- Details of how problems were dealt with
- Evaluation of the design against the original specification criteria
- Analysis of and modification suggestions for designs not meeting criteria
- Testing methods used

Question 2

What are Technical reports used for

Answer 2

• Recording practical test results
• Target market research
• Reviewing products relevant to design development

Question 3

The use of graphs, tables and charts

Answer 3

Bar chart
- Simplest way of representing data
- Used in many different reports and in the media
- Commonly used
Pictograph
- Very easy to understand
- Quick to read
- Suitable for presentations
- Not very accurate
Histogram
- Similar to a bar chart
- Data is shown in ranges
- Useful to show the frequency distribution of data
- Particularly useful for showing results of research
Line graph
- Can show data changes over time
- Easy to understand
- Accurate due to the use of scales
Pie chart
- Shows data distribution
- Size of segments is relative to the proportion of data
- Very easy to read and understand
Data tables
- Important to enable you to:
• interpret data
• identify patterns or incorrect data
• add missing data
- Typical project use:
• anthropometric data
• cutting lists
• costings

Question 4

Sectional drawing

Answer 4

• Shows internal, hidden details of an object

- The object is usually ‘cut’ in half along a ‘cutting plane’

Question 5

Thick/thin line technique

Answer 5

• For 3D drawings to stand out
• External edges are bold and thick
• Internal lines are thin

Question 6

Marker rendering

Answer 6

• Sprit-based markers are used
• Provide a base colour
• Additional layers of colour or tone can be added
• Fine-line pens add more detail
• Enhances realism of drawings

Question 7

Mixed media drawings

Answer 7

These make use of:

        - pencil and fine-line pen for detail
        - marker pen
        - watercolour for are cover
        - realistic textures are possible

Question 8

Texture rendering

Answer 8

• Added using a fine-line pen
• Specific materials can be suggested
• Texture includes:
  • wood grain
  • cross-hatching
  • stippling

Question 9

Orthographic projection

Answer 9

A technique used to draw the front, plan and end elevation of an object

Question 10

Isometric

Answer 10

A 3-D drawing technique using 30° lines
typically used in sketching ideas

Question 11

Crating

Answer 11

Using a 3-D box and constructing drawings inside them, parallel to the outer lines of the box

Question 12

Perspective drawings

Answer 12

3-D drawings that use one or two vanishing points.
They are often used for design ideas or presentation drawings
