principles to produce effective solutions.
This unit covers the triggers that motivate the need for new designs,
potential challenges to and constraints on your design, how to specify
what you want from your product, the use of iterative processes
to develop an effective solution, and how to analyse, validate and
communicate your work.

, Getting started
Work in groups to list all the things you might want from a particular
product. Write down what you think these requirements might mean in
terms of the decisions the designer would make - consider the cost of
manufacturing the product, the materials used, the product's strength and
durability, its sustainability and reliability, and so on.
I Design triggers, challenges, constraints and
opportunities, and materials and processes
A1 Design triggers
The initiation of a new product does not normally happen spontaneously.
Generally, there will be some sort of trigger that motivates a new design activity.
Market pull or technology push
Market pull
Market pull refers to the development of new designs based on a need for either a
completely new product to meet some demand or an improved product to address
customer dissatisfaction with existing products. In the automotive market, for
example, customers are always looking for better fuel economy, greater comfort and
improved safety; as a result, manufacturers tend to focus on these areas.
The identification of these needs may be through informal customer feedback, such
as sales agents chatting with customers, or more formal market research. Market
pull can also arise from the pressure to upgrade a product in response to competitor
developments.
Customer feedback and market research can be used to identify areas of the
market where a new product with the correct characteristics could make an impact.
By definition they indicate what customers want, so if this can be delivered as required
and on time, a commercially successful product should result.
Market pull does, however, have its limitations. Customers may be able to identify a
need, but the technology to turn this need into a real product may still be some way
off. For example, there may be market demand for a hoverboard or teleportation
device, but if it cannot be produced with current technology, then it will not become
reality. Designers also have to carefully consider the timeliness of the need - customer
demands may change or even be completely superseded over the product's
development cycle, so that the engineering company may end up giving the customer
what they wanted three years ago, not what they want now.
Technology push
Technology push refers to the development of new designs made possible by the
introduction of new processes or technologies. In the case of manufacturing, it may
mean that products can be produced much more cost-effectively, reliably or to a
greater precision than was previously possible. Technological advances may also allow
new features and functions to be incorporated into a product. For example, advances
in electronics, sensors and touchscreens have led to the emergence of a completely
new market in smartphones and tablets since 2010.
