Opt0-Mechatronic System Design
Dein Shaw
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
Design and product
1.1 Measuring the Design Process with product cost, quality and time to market
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
