Mechatronic Design Process
Mechatronic Design Process
The mechatronic design process is a structured approach to developing mechatronic systems, involving three key phases: modeling and simulation, prototyping, and deployment.
Identify Problem & Need
Identify Problem & Need
The identification of a problem and the corresponding need is the foundational step in the design process. It sets the stage for defining the objective and creating a system to tackle the problem.
Needs Hierarchy
Needs Hierarchy
A needs hierarchy is a structured way to categorize and prioritize the needs that a design must address, starting with the most general and branching down to more specific ones.

Study Notes
Mechatronics Systems Design (MCT 317) - Lecture 02
- Course: Design of Mechatronics Systems (1)
- Lecture: Mechatronics Product Design Techniques and Methodology
- Instructor: Dr. Eng. Mohamed Nabil
- Assistant Professor, Mechatronics Department
Product Development Life Cycle
- A cyclical process featuring stages like Requirement Gathering & Scoping, Research & Usability Engineering, Prototyping, Development, Testing & QA, Deployment, and Maintenance & Technical Support, Training & Sales Support.
Mechatronics Design Process
- A major factor in the traditional approach is the complex nature of designing multidisciplinary systems.
- Mechatronics represents an improvement over existing lengthy and expensive design processes.
- Consists of three phases: Modeling and Simulation, Prototyping, and Deployment.
Detailed Mechatronics Design Process (Diagram)
- Includes steps like Recognition of the need, Conceptual Design and Functional Specification, First principle modular Mathematical Modeling, Sensor and Actuator selection, Detailed modular Mathematical Modeling, Control system Design, Design optimization, Prototyping, Software in the loop simulation, Design Optimization, Deployment of Embedded systems, Life cycle optimization.
Example on Identifying a Problem & Need
- Need: Drivers experience difficulty seeing obstructions in all directions.
- Objective: Design a system to prevent accidents.
Example Needs Hierarchy
- Focuses on needs for portable audio devices, including high-quality audio, low distortion, low noise, portability (lightweight, small size, ergonomic design), environmental factors like outdoor temperatures, runner's shock, and drop/water resistance. Also features "Easy to Use", "Limited Controls," "Multiple Data Formats"
Requirements Specification
- Identifies the necessary requirements for a design to be successful.
- Includes key aspects including both marketing requirements (customer needs) and engineering requirements (technical & performance-based criteria).
Product Design Specifications - Customer Needs (Rope Climber)
- Customer requirements for a rope climber include climbing speed, cost-effectiveness, full assembly, battery-powered operation, safety, aesthetics, musical accompaniment during ascent, and extended functionality like night-time visibility.
Product Design Specifications - Engineering Needs
- The design specifications include climbing speed at minimum 1 ft/s, a retail cost under $30, use two AA batteries (excluding battery cost), and includes manufacturing limitations like no removable small parts. Sound limits around 20-30 db, and acceptable luminosity over 5W. Functional duration is 3+ hours using two AA batteries.
Product Design Constraints and Requirements
- Engineers must consider various constraints, such as technical, economic, social, and environmental issues, during the design process.
- Evidence of addressing relevant constraints must be documented in the project.
Functional Constraints
- The design needs to consider factors like overall geometry, motion of parts, involved forces, energy needs, material selection, control system design, and information flow, all of which are essential.
Safety Constraints
- Operational safety, including the avoidance of direct and indirect hazards, should be prioritized. This includes human factors (warnings and training) and environmental concerns (land, sea, air, noise, light, radiation and transport).
Manufacturing Constraints
- Manufacturing constraints include factory limitations, waste management, supplier quality, assembling (installation, founding, bolting, welding) and packaging.
Methods for Development of Mechatronic Systems
- An example is included about a company (High Tech Washing Ltd.) developing a new washing machine that washes faster and is more cost-efficient than current models.
1 - Pre-Analysis
- Develops a washing machine using a technique similar to hand washing, achieving increased efficiency and eco-friendliness while decreasing costs.
- Identifies the target market (Europe, Northern America, and Japan) and customer profile (average or high income, concern for cost-efficiency and ecology).
2 - Requirement List
- Specifies requirements with details like size (height, width, length), washing time, water use, detergent type, and color. Lists are categorized for fixed, range, quantitative, and qualitative requirements.
3 - Functional Structure
- Describes the functional flow chart, showing the electrical energy, conversion, mechanical energy, water, and laundry stages to reflect the function of a washing machine.
4 - Finding Solutions for Each Function
- Describes the brainstorming methods used to generate multiple washing solutions followed by filtering/evaluation.
5 - Evaluating the Best Solution
- Presents a table comparing and evaluating different solutions based on various criteria like time of washing, cleanliness of laundry, ease of handling, and ecological factors.
6 - Layout Process
- Defines the layout using modules for mechanics, electronics, and software, with relevant graphical descriptions.
Questions
- The final slide asks if any final questions remain unanswered for further discussion.
