The Design Process
Evolution of Product Design
Manufacturers Try to Continually Improve Products
Manufacturers always want to make more money
Manufacturers want their products to be as good as possible
Manufacturers redesign products to suit market pull
Market Pull is About What Consumers Want
Designers design stuff to satisfy the customers wants and needs
Changing fashions and attitudes affect the products people want
Technology Push is About What Manufacturers Can Provide
Research departments are coming up with new technologies
Manufacturers use new technology to develop new products
New technology makes a product cheaper and nicer-looking - more desirable
Products Can Evolve for Other Reasons
Some products evolve because of social need
Others because there's a political need

Ergonomics Means Making the Product Fit the User
Ergonomics is how easy a product is to use
Products need to be designed with correct proportions
Designers use body measurement data to clarify this
Badly-designed products have long-term health impacts
Manufacturers Design for 90% of the Target Market
Manufacturers design products to be suitable for most people
Manufacturers try to make 'one size fits all' products
the bottom and top 5% aren't catered for
These people would need a specialist supplier
Research and Specifications
Designing Starts with the Design Brief
The person who hires the designer is the client
The designer receives the design brief
The design brief is the starting point
You need to pick out all important features
One way is by doing a spider diagram
Research Helps You Get Ideas
The point of doing research is
Check people will want it
Find out what the target market likes
Find out what materials are suitable
Market research
Product analysis
Then you have an idea of materials and techniques
Use Your Research to Draw Conclusions
It'll have a lot of information
Summarize what you've found out
Explain what impact each has
The Design Specification is a List of Conditions to Meet
The design specification gives conditions for it to meet
It's best to write a specification in bullet points
