Design Principles
Objective:Analyze a design in terms of flexibility, balance, function, and proportion.
Warm-Up
• List all the functions that modern cell phones can perform.
Hardware vs Software Design
• When you design modern technology, you often have to design both hardware and software
• Is a phone useful without software?• Is a phone possible without
hardware?• Do people care about the
design of both?

Design Principle 1: Flexibility
1. A product should be readily able to accommodate change.
2. Future needs3. Change in use or function

Flexible: Many Uses

More Examples of Flexibility
• Video game consoles that work on different tvs and games that are visible on different size screens
• A web site that can accommodate various browsers, screen resolutions, operating systems
• A planetary robot rover able to move across various surfaces, in various conditions (extreme heat and cold)

Analyzing the iPhone
• What examples of flexible design do we see in the iPhone?
• Flexible input system: screen can change configurations and use
• Apps: accommodate change in needs rapidly

Design Principle 2: Balance
• Parts of the design are equally distributed to create a sense of stability.
• There can be physical as well as visual balance.• Types
– Symmetrical or Formal Balance– Asymmetrical or Informal Balance– Vertical and Horizontal Balance

BalanceSymmetrical Asymmetrical

Symmetrical Balance
• The elements within the design are identical in relation to a centerline or axis.
• The apps are arranged according to a grid
Radial Balance
What kind of balance is illustrated?
Symmetrical Balance
Design Principle 3: ProportionThe relationship in size of:
• one component to another
• The item to the user

Proportion
• Buttons aren’t too big or small
• What examples of proportion do you see?

Design Principle 4: Function
• Each part has a purpose• Functional decomposition - split up a complex
function into many sub-functions.
page 21
Functional Design Questions
• What is the product’s goal?• Who will be using it?• Is it clear how to use it?• How does the user know its
working?
Hardware vs Software Design
• Both can be appealing to the customer• Both can look good• Both can be easy to use• Both can be comfortable / intuitive• Both can have flexibility in their design

Design Analysis
• Analyze a robot based on the four principles of design
• Give examples of each of the design principles:– Flexibility– Function– Proportion– Balance
