Aims
today
Roles of design models and prototypes
Prototyping strategies
Experimental / testing plans for the chosen
exhibit design
Identify appropriate procedures, variables,
performance measures, ranges of interest, and
trials
Concepts
Preliminary engineering drawings and
Bill of materials (BOM)
Beta prototype (scaled model +
functional model)
Cost estimate
Embodiment
“In embodiment design, we provide form to
the selected concept(s)”
Form: geometry, components, materials,
manufacturability, economics
Strategy: to refine these factors iteratively,
from an abstract form to a concrete one
http://www.hcdconnect.org/toolkit/en
Build physical representations to learn from
your ideas and make increasingly concrete
and detailed decisions
Analytical Models (Mathematical, Physics)
Design Models (Virtual, Experimental,
Empirical)

Why
prototype?
•Reduce uncertainty
•Make assumptions explicit
•Learn a specific feature or property
•Evaluate alternatives
•Gather feedback and data
•Communicate a key decision
•Explore a range of values across variables
•Safety and ergonomics
•Test manufacturing and assemblies

Key Q’s Functionality being tested?
Scales, assemblies and materials?
Structural behaviour and costs?
Physical or virtual prototype?
Decisions to build model/prototype:
materials, processes, time, modifications…
Single plan or replan?
Parallel or serial prototypes?
Simultaneous or iterative?
Important
Good investment: plan resources & time
Make your goals and questions explicit
Learn from your models and prototypes: test,
measure, modify them
Document, record and analyse evidence
