Chapter 1 Introduction

What is design?

Design is a process planning which plan how the thing works as wished.

What is defferent between human control and meachine control?

Opto-Mechantronics system configuration:

What is Opto-Mechtronic System Design?

Electrical Subsystem –

Electro dynamics

Mechanical Subsystem –

Mechanical dynamics

Optical Subsystem –

Optical system character

Ideal EnergyTransformer

Same function but different methods:

Example of Color scanner

Example of Color scanner

CCD sensor speed is much larger than the motor speed

1.2 Life of a product

1.3 Different type of system design problem

1. Selection design

2. Configuration design

3. Parametric Design

4. Original design

5. Redesign

1.6 Design Process

1.7 communication during design

• Design Record-design note book• Documents communicating with management-

design reviews• Documents communicating the final design

-drawing of components and assemblies

-written documentation to guide manufacturing, assembly, inspection, installation, maintenance, retirement and quality control
