Common

Common…….

  • They are “created” for a purpose, a “function.” Most fulfill multiple functions.

  • All have some sort of shape, a “form.”

    The shape relates to the function, the usage of the device, materials implementation, aesthetics, and many other factors.

  • All are made by using “material.”

  • Virtually all have “cost” considerations.

  • Others have: safety, environmental, simplicity, aesthetics, usability, comfort, …considerations.

Engineering design1

Engineering Design

Function: To receive signals from the beacon, analyze, send information to controller. (input/output).

Form: Most simple rectangle, except the receivers: semicircle.

Reason: usage requires wider angle.

Material: Epoxy resin, electronic components

The key elements of product design

The Key Elements of Product Design

  • Function: All products and services have one or more. It is the reason you are building the product. It is the purpose of your design.

  • Form: The final form of a product, or a structure, is the result of many factors: -The way you achieve the function, the “solution”, -The available material, their use , their properties, and their influence on aesthetics, cost, environment etc.

  • Materials: The availability and properties have direct effect on the form of the product: strength, weight, flexibility, weathering, environmental impact, aesthetics, temperature, cost, etc.

Question 1

Question 1

The final form of a structure is the result of the following factor(s):

  • The use of the material

  • The properties of the material

  • The way the function is achieved.

  • The cost and availability of the material

  • All of the above

Question 2

The three most important elements of a design are?

Form, Shape, Looks

Form, Shape, Size

Purpose, Scope, Cost

Function, Form, Materials

Responsibility, Applicability, Compatibility.

Design

Design

  • The Verb

  • To form an idea

  • To plan by drawing the outline

  • To sketch

  • To contrive

  • To project with an end in view

The Noun

  • a project

  • a sketch to work from

  • a creative activity

  • ‘an arrangement of parts, details, form, color... as to produce a complete artistic unit’

The engineering design process

The Engineering Design Process

  • Need for the product or the service

    There has to be a need for the product or the service.

    • Who defines it? Society - Government

      Market: Customer – Consumer

      Need for: Transportation, Communication, Health, Education Food-processing, preservation, delivery, Defense, Entertainment, Comfort, Business , …

      E10 Laboratory Projects?

  • Customer Requirements

    What customer ordered: product or services. (You may have to help your customer define his need)

JKA_ 2009


The engineering design process cont

The Engineering Design Process (cont.)

  • Define The Need: Once the need has been established, the first step of the engineering process is to define the problem on hand.

  • BUT, before you define a problem you need to understand it.

  • Evaluate the project constraints.

  • Translate customer requirements into a workable/ engineering concept.

  • What are the requirements/specifications of the turbine project???????

Define

Problem

  • Gather Information (Research) for all “How to” elements.

  • 10 – 30% of an engineers time can be spend on this step.

  • It is continuous rather than a one step activity (“Learning Curve” applies)

    • Applicable engineering principles

    • Materials, properties, procurement .

    • Tools and equipment, how to operate.

    • Etc.

  • E10 Research: Aerodynamics, Inventor 2008, Structural , Electrical, Tech. Communications

Problem

  • Brainstorming: An activity designed to generate a lot of ideas/solutions.

  • Quantity is of importance - design has many solutions

  • Build on the ideas of others

  • Focus on Function

    - No criticism

    - All ideas are welcome

    • No limits or boundaries

    • No hesitation

      Sketching : a graphical presentation of an idea

The Engineering Design Process

Constraints: Turbine height = 17 in

Stiffness vs. light weight

Criteria: “constraints” you place on your design, for best performance,

based on your design, materials ,

safety, environmental…

If you had to build the turbine:

Land, excavation, cost, location, access
