The Process of Design

MVHS Intro to Engineering

Thinking

What is a good example of the problem solving process?

What is a good definition of the design process?

What are the major steps in the design process?

How are creativity and innovation parts of the design process?

Design Process

Design is the process of planned change By accident! Design goal

Design Process

Definition- a systematic problem-solving strategy, with

criteria and constraints, used to develop many possible solutions to solve a problems or satisfy human needs and wants and to narrow down the possible solutions.

Problem Solving

The process of understanding a problem, devising a plan, carrying out the plan, and evaluating the effectiveness of the plan in order to solve a problem or meet a need or want

Scientific Method

1. Characterization: Observations or measurements

2. Hypotheses: Theoretical explanations

3. Predictions: Reasoning using logic

4. Experiments: Tests of all the above

Thinking

How is the design process different to the scientific method?

The Design Process

ASK IMAGINE PLAN CREATE IMPROVE

The Design ProcessASK

•What is the problem?

•What have others done?

•What are the constraints?

IMAGINE

•What are some solutions?

•Brainstorm

•Choose the best

PLAN

•Draw diagram(s)

•List materials and equipment needed

•Estimate what to do, by whom, when

GOAL

CREATE

•Follow your plan and create

•Test it out

IMPROVE

•Make your design better

•Test it out

Brainstorming

Rules: No Critizism Work for quantity Welcome “piling on” Allow free-for-all

Agenda? Marker rule

Design Brief

A written plan that identifies a problem to be solved and its criteria and constraints.

A design brief encourages thinking of all aspects of the problem before attempting a solution.

Computer desk areas tend to be very cluttered. A variety of desk items 9blank paper, printed papers, paperclips, tape, etc.) as well as a plethora of computer cables and attachments are all typically very cluttered and unorganized, causing major loss of work efficiency

Design, model, and test a prototype modular commercial computer desk system that will substantially reduce desk and computer cable clutter, leaving ample computer connectivity (USB, firewire, etc.)

3 mo. Design and prototype, (ii) $175 max mfg. Cost (qty of 100,000) –base unit, (iii) $250 max. mfg. cost (qty of 10,000) – fully optioned, (iv) 8 sq. ft. min. surface working area (st. 30” height), (vi) max. shelving height of 7”, (vii) less than 130lbs – fully optioned

(i) Sketches showing breadth of ideas, (ii) Design journal, (iii) technical drawings, (iv) Mfg. cost estimates, (v) Development schedule and cost estimates.
