stakeholders.


What are your burning questions?


What is a
Prototype
?

A model to test an
aspect of a
product’s
feasibility, dealing
with the burning
questions

Types of technical prototypes

– Proof-of-Principle Prototype
– Form Study Prototype
– User Experience Prototype
– Visual Prototype
– Functional Prototype
http://en.wikipedia.org/wiki/Prototype


Proof-of-Principle Prototype
A proof of concept prototype is used to test some aspect of
the intended design without attempting to exactly simulate
the visual appearance, choice of materials or intended
manufacturing process. Such prototypes can be used to
"prove" out a potential design approach such as range of
motion, mechanics, sensors, architecture, etc. These types
of models are often used to identify which design options
will not work, or where further development and testing is
necessary.

In electronics this is sometimes: “built on a breadboard”.


Dyson – 5127 prototypes

The hammer test
When James started out he tested prototypes by dropping them
down a cast iron stairway at the back of his workshop. Simple but
effective.
These days Dyson prototypes must endure 550 tests. Hoses
are contorted and stretched. Cleaner heads are slammed into iron
table legs. Performance is tested in temperatures as low as -20c
in an environmental chamber. Things haven’t changed all that
much though. Every 100th bin off the production line is whacked
with a lump hammer just to make sure.

Form Study Prototype
This type of prototype will allow designers to explore the
basic size, look and feel of a product without simulating
the actual function or exact visual appearance of the
product. They can help assess ergonomic factors and
provide insight into visual aspects of the product's final
form. Form Study Prototypes are often hand-carved or
machined models from easily sculpted, inexpensive
materials (e.g., urethane foam), without representing the
intended colour, finish, or texture. Due to the materials
used, these models are intended for internal decision
making and are generally not durable enough or suitable
for use by representative users or consumers.

User Experience Prototype
A User Experience Model invites active human interaction
and is primarily used to support user focused research.
While intentionally not addressing possible aesthetic, this
type of model more accurately represents the overall
size, proportions, interfaces of a concept. This type of
model allows early assessment of how a potential user
interacts with various elements, motions, and actions of a
concept which define the initial use scenario and overall
user experience. As these models are fully intended to be
used and handled, more robust construction is key.
Materials typically include plywood, REN shape, RP
processes and CNC machined components.


User Experience


Visual Prototype
To capture the intended design aesthetic and simulate the
appearance, colour and surface textures of the intended
product but will not actually embody the function(s) of the
final product. These models will be suitable for use in
market research, executive reviews and approval,
packaging mock-ups, and photo shoots for sales literature.

Functional Prototype
To the greatest extent practical will attempt to simulate the
final design, aesthetics, materials and functionality of the
intended design. The functional prototype may be reduced
in size (scaled down) in order to reduce costs. The
construction of a fully working full-scale prototype and the
ultimate test of concept, is the engineers' final check for
design flaws and allows last-minute improvements to be
made before larger production runs are ordered.

What about
Market
Prototyping
?

Sun cream on demand

What are the burning
questions related to the
market feasibility of this
product?


The burning questions about market
feasibility of sun cream
1. How much variety is required in SPF ?
2. What are the primary locations for sales?
3. Will customers change their mindsets/habits?
4. How many (% & Vol.) people forget to bring
SC?
5. What are customers willing to do to receive the
product?
6. What is the required dosing sizes?


Choose a couple of the
questions and discuss
how you could test the
feasibility using a
prototype

of people might want to
buy the finished

you can’t think of who
would definitely be
the first customer

For Next Tuesday’s Additive Manufacturing
Lecture

You need to download...

Net fabb: http://www.netfabb.com/download.php
Cura: http://wiki.ultimaker.com/Cura

And a CAD package (ideally SolidWorks).

Make sure one member of you team brings a laptop to the lecture with the
above installed!


For Friday at the Innovatorium

13:00 – 14:20 Show and tell of your projects
- At your table set up a small display of your project.
- Bring a prototype and graphical images if you can
- Look around the innovatorium and speak to people who will be able to
help you out with your project (technicians/floor manager)
- Find out about ordering materials, booking facilities and getting trained
up on the equipment.

We may spend the rest of the semester in there so get to grips with it!

14:20 – 16:00 Talks on innovation and the innovatorium (Danish)

16:00–17:00 More show and tell with food and refreshments.
