Testing / Analysis • Modelling • Predictive Analysis • Testing Sheik Masthan SAR | AP Mechatronics | TCE | MDU 3

Various Modelling Mathematical Physical Sheik Masthan SAR | AP Mechatronics | TCE | MDU Computer 4

Modelling - Mathematical • Sheik Masthan SAR | AP Mechatronics | TCE | MDU 5

Modelling - Physical • 3 -D replicas of the final design of a solution • Used to illustrate the design, test the design, or experiment with materials • Falls under 2 categories • • Mock-up Prototype Sheik Masthan SAR | AP Mechatronics | TCE | MDU 6

Modelling - Physical • Mock-up • Either full size or scaled do increase or decrease the size of the object • Usually created with paper, cardboard, foamboard • Used to simulate the appearance of the final product • Not a working model Sheik Masthan SAR | AP Mechatronics | TCE | MDU 7

Modelling - Physical • Mock-up Sheik Masthan SAR | AP Mechatronics | TCE | MDU 8

Modelling - Physical • Prototype • Used to simulate the function of the final product • A working model using rapid prototyping Sheik Masthan SAR | AP Mechatronics | TCE | MDU 9

Modelling - Computer • Structural Engineer – Bridges • Computer simulation to check the strength of the bridge during an earthquake Sheik Masthan SAR | AP Mechatronics | TCE | MDU 10

Modelling - Computer • Modelling and simulation of a Robotic Arm Sheik Masthan SAR | AP Mechatronics | TCE | MDU 11

Predictive Analysis • Predict the future events using factors such as • Statistics & Probability • Models • Mathematical & scientific principles Sheik Masthan SAR | AP Mechatronics | TCE | MDU 12

Testing • To determine the usefulness of the product • Criteria for testing • Function • Fit • Aesthetics • Safety • Environmental Impact Sheik Masthan SAR | AP Mechatronics | TCE | MDU 13

Testing – Criteria • Function • Test the working of the product • Whether the product solves the problem of concern ? • Does the product meet the minimum requirements ? • Will the design / product withstand daily use ? • Etc. …… Sheik Masthan SAR | AP Mechatronics | TCE | MDU 14

Testing – Criteria • Fit • Whether the product works with production and customer needs ? • Eg: Inability to place the power switch in the specific location in the mobile phone • Aesthetics • Visually appealing • Will consumers purchase the product based on its appearance ? • Size, color, few others Sheik Masthan SAR | AP Mechatronics | TCE | MDU 15

Testing – Criteria • Safety • Safe to produce ? • Safe for customers to use ? • Electrical hazards, chocking hazards • Met government regulations ? • Environmental Impact Sheik Masthan SAR | AP Mechatronics | TCE | MDU 16

Testing – Criteria • Environmental Impact • Product disposal method • Product’s ecological footprint • Potential risks if the product malfunctions Sheik Masthan SAR | AP Mechatronics | TCE | MDU 17
