    Study Notes

    Introduction to Engineering Design - Semester 1 Midterm

    • Big Four Fields of Engineering:
      • Mechanical Engineering: Designs, develops, builds, and tests equipment and sensors for moving objects.
      • Electrical Engineering: Deals with circuits, power generation, distribution, machine control, and communications.
      • Civil Engineering: Focuses on design, construction, and maintenance of the built environment.
      • Chemical Engineering: Designs, builds, tests, and manages the efficient use, production, transformation, and transport of chemicals, materials, and energy.

    Unit 1: The Design Process

    • Engineering Notebook: Keeping a well-organized notebook with best practices is important for efficient engineering.
    • Brainstorming: Brainstorming is essential for generating many possible solutions.
    • Design Process: A design process is a systematic approach to problem-solving.
      • It involves steps like defining the problem, generating concepts, developing solutions, constructing and testing, evaluating solutions, and presenting.
      • The process is iterative; each step often feeds back into previous steps.
    • Design Brief: A design brief includes the problem statement, criteria (requirements), and constraints (limitations).
    • Engineering: Engineering is a systematic problem-solving approach using scientific and technical knowledge.
    • Engineers: Engineers use scientific and technical knowledge to solve practical problems and design solutions. There are four major disciplines (mechanical, electrical, civil, chemical).

    Design Process Definition

    • A design process is a systematic step-by-step approach for solving problems and satisfying needs/wants. The steps include defining the problem, generating concepts, developing solutions, constructing and testing, evaluating solutions, and presenting.

    General Notes

    • Technical Drawings/Sketching: The document includes significant information about various types of lines (center lines, construction lines, dimension lines, extension lines, hidden lines, etc.) used in technical drawings. The types of drawings (orthographic projections), isometric sketches, and sketching conventions are also discussed.
    • Measurement Techniques: Precision vs. accuracy, significant digits, measuring tools and how to use them (like calipers) are essential to follow during measurements. Measurement procedures and summarization of data (mean, median, mode, standard deviation) is critical to quality in engineering.
    • CAD Fundamentals: Concepts like creating 3D models (extrusions, revolutions, polygons, etc.) using computer-aided design (CAD) are discussed.
    • Hole Notes/Thread Notes: Understanding different types of holes (through, clearance, blind, counterbore, and countersink) is essential. The use of standardized symbols and geometric constraints in drawing are highlighted.
    • Orthographic Projections: Understanding the minimum number and types of views in orthographic projections is vital for a complete representation of an object. Selection of front views in technical drawings is also important.
    • Dimensioning: Drawing dimensions and their applications are covered. Correct and incorrect dimensioning practices are mentioned as well as the use of appropriate scales.
    • CAD Assemblies: How to create CAD assemblies, parts lists, and their components/assembly drawings are all essential aspects.
