Study Notes
Mechatronics Design Processes
- Mechatronics design is an improvement on existing design processes, as it tackles multidisciplinary systems.
- The traditional sequential approach is inherently complex due to the multidisciplinary nature of the design.
- The mechatronic design process has three phases: modeling and simulation, prototyping, and deployment.
Product Development Life Cycle
- The product development life cycle is a cyclical process.
- Key stages include requirement gathering and scoping, research and usability engineering, development, prototyping, testing and QA, deployment, and maintenance & technical support, and training & sales support.
Stages of Mechatronics Design Process
- Modeling/Simulation: 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, Software in the loop simulation, Design optimization.
- Prototyping:
- Deployment/Life cycle: Deployment of embedded systems, Life cycle optimization.
Example on Identify Problem & Need
- Need: Drivers have difficulty seeing obstructions in all directions
- Objective: design system to avoid accidents
Example Needs Hierarchy
- Key features for a portable audio device include: high quality audio, low distortion, low noise, portability, lightweight, small size, ergonomic design, environmental considerations such as outdoor temperatures, runner's shock, drop resistant and water resistant design.
- Features like easy to use, limited controls, multiple data formats (MP3 or CD Audio format, CD, Flash Memory), long battery life, are also important considerations.
Requirements Specification
- Requirements specification identifies necessary qualities a design needs for success.
- Marketing requirements include customer needs.
- Engineering requirements include technical aspects and performance requirements.
Product Design Specifications
- Specific requirements for a rope climber include that it must climb quickly, cost-efficient for a birthday gift, be completely assembled, be powered by batteries, and be safe. Aesthetic considerations include a pleasing appearance. Functionality includes music playing while climbing and glowing in the dark to maintain visibility. Durability is also desired, with a long lifespan.
Product Design Engineering Specifications
- Design engineers must address physical function. Specific design criteria include factors like climbing speed, cost limitations, battery type, and parts that cannot be removed.
- Functional criteria like the sound output range (20-30db) and adequate brightness (luminosity >5 W) and battery performance (3+ hours using standard 2 AA batteries) are included.
Product Design Constraints and Requirements
- Engineers must consider technical, economic, social, environmental and political constraints in product design.
- Projects must demonstrate a clear understanding of constraints relevant to the project.
Functional Constraints
- Functional constraints include overall geometry (size, width, space, arrangement), motion of parts (type, direction, velocities, acceleration, kinematics), forces involved (load direction, magnitude, load, impact), energy needed (heating, cooling, conversion, pressure), materials to be used (flow, transport, properties), control systems (electrical, hydraulic, mechanical, pneumatic), and information flow (inputs, outputs, form, display).
Safety Constraints
- Safety constraint categories include operational safety (eliminating direct, indirect, and hazard risks). Human safety factors include warnings and training. Environmental considers land, sea, air, noise, light, radiation, and reaction and transport.
Manufacturing Constraints
- Manufacturing constraints include the production process for components (factory limitations, production methods, waste considerations), sourcing components (supplier quality, reliability, quality control, inspections), assembly (installation, foundations, bolting welding), and transportation (material handling, clearance, and packaging).
Methods for the Development of Mechatronic Systems.
- An introductory task scenario describes developing washing machines for a company, identifying the need for increased efficiency and ecological wash processes.
1- Pre-Study Process—Analysis
- Developing a washing machine with a similar technique to hand washing will be more efficient and eco-friendly with lower costs.
- Early market targets are well-developed nations of Europe, North America, and Japan.
- Target customers will be average-to-high income individuals who value eco-friendly strategies and cost efficiency.
2- Requirement List
- Requirements include fixed and variable attributes like size (height, width, length), washing time, water usage, type of detergent and color.
3- Functional Structure
- Functional structure diagrams illustrate the step-by-step washing process from cold water introduction, heating, merging water with detergent, to kneading, rinsing and final water removal..
4- Finding Solutions for Each Function
- This process involves brainstorming, evaluating ideas based on specifications, filtering for solutions matching needs, and simplifying/combining solutions. Solutions with significant overlap are eliminated.
5- Evaluating the Best Solution
- Evaluation uses a rating scheme based on criteria like wash time, laundry cleanliness, ease of handling, and ecological impact
6- Layout Process
- Key modular design consideration involves mechanics, electronics, and software integration to design the overall product.
