Design Strategies Flashcards
What is iterative design
Iterative design is cyclical approach
Each iteration of the design is testing about rating changes are made leading to a new iteration
Examples of iteration
Dyson vacuum cleaners thousands of different prototypes
Advantages of iterative design
Because each iteration is fully tested and evaluated it’s more likely that problems with the design will be discovered in dealt with earlier
User feedback is constantly being gathered
Evidence in progress of the product can easily be provided to investors
Disadvantages of iterative design
Designers can be too focused on the current iteration that they lose sight of the bigger design
Can be time-consuming and waste a lot of material
What is user centre design
User centred design is an approach where the needs and wants of the use of a considered extent to be at each stage of the design process
Advantage of user centred design
The final product will meet their users expectations there is a greater sense of ownership of the product because they had input every single stage
Disadvantage of using sense of design
Can become too focused on a single clients it may be unavailable to sell to the wider public
Takes a lot of time to continuously hold meetings and discussions with the client
What is system thinking
It’s a top down approach that starts with an overview of the overall system and then subcategories with detail of each aspect of the system
Advantages of systems approach
Does not require a high specialist knowledge
Top-down approach makes it easy to communicate with clients and stakeholders
Disadvantage of systems approach
Because of the block base design approach it can lead to the use of components that are necessary if the necessary components are used it can lead to extra costs
Why are prototypes used
To check how the product would look and function they can represent this to the clients to gain feedback
Problems with the design are spotted earlier before too much time and money are spent on materials and manufacture
Tools for evaluating of prototype
Cost Aesthetics Function Ergonomics Quality User Environment
Corn starch polymers
Plastic made from vegetable starch biodegradable and can be used for animal feed. Readily decomposed good for the environment and are commonly used in packaging.
Polylactic acid
These are biodegradable polymers just move or textured available in a range of colours.
Non-toxic easily moulded widely used in bottles and phone cases.
PHB Biopol
Limited chemical resistance
Biodegradable polymers that are smoother texture available in a range of colours
