What is the role of the designer?

Prepare the plan for the transformation of concepts and ideas into concrete and tangible products using available resources

Design documentation

Communication of ideas andconcepts into colleagues and workers

Assigning responsibilities between designers, machinist and workers who Implement the design

Types of Drawings

• Artistic Drawings • Technical Drawings • Illustrations or Renderings

Design - the plan and arrangement of the form and structure of natural and man-made material to achieve a desired function.

Engineering - the application of sciences to the construction of hardware or/and software.

Engineering design - an iterative decision making process in which sciences are applied to devise a system to meet the needs of the client.

Problem Identification

summarize client's needs in the design specification

Conceptual Design

brainstorm to figure out potential solutions and record them in notes and sketches

Preliminary Design

analyze using experience, logic, math, sciences, and graphics test engineering models

Detailed Design optimize the design solution

Implementation and

Documentation

create fabrication specifications and working drawings

Problem Identification

summarize client's needs in the design specification

Problem Statement

Although feeding device are available for people suffering from paralysis, they are often bulky, expensive, and not portable. A need exists for a simple feeding device. It should be electromechanical and operate from its own power source. The design should be economical, have a light weight, and be simple to use and maintain.

Project Title

Design of an Economical Potable Feeding Device for Patients of Paralysis

~2000BC – a drawing carved on a tablet for a temple in Babylonian Empire ( from a collection of Louvre)

Perspective drawing technique was invented during the Renaissance period (1300-1500)

Parallel projection technique was invented during the Industrial Revolution period (1750-1850)

2-D CAD systems were developed in the 1980s

3-D CAD systems were developed in the 1990s

The Boeing 777 is the first jetliner to be 100 percent digitally designed using three-dimensional computer graphics. Throughout the design process, the airplane was "pre-assembled" on the computer, eliminating the need for a costly, full-scale mock-up.

Dodge Neon was designed using 3-D CAD system CATIA

Concurrent Engineering is the 21st century star
