Study Notes

Engineering Design and Computing

Engineering Design & Computing is an interdisciplinary field requiring collaboration from various specialists.
This field focuses on the development of products and systems that solve real-world problems.
The process typically involves several stages, including:
- Requirements: Defining the needs and constraints of the project.
- Ideation: Generating ideas and concepts.
- Technical Drawings: Producing detailed representations of the design.
- Prototyping: Creating physical models to test and refine the design.
- Material Selection: Choosing materials based on their properties and sustainability.
- Manufacturing: Producing the final product.
Several tools aid this process, like:
- Sketches: Simple representations of ideas used in the concept generation phase.
- Computer-Assisted Design (CAD): Software used to create 3D models and drawings.
- Additive Manufacturing: A technology for building 3D objects layer by layer.
- Ashby Diagrams: A tool for comparing and selecting materials based on their properties.
Sustainable design is a key consideration in modern engineering design. This means designing products and systems that minimize their environmental impact throughout their lifecycle.

Sketching

Sketching is a simple communication tool used in the early stages of design.
It's often referred to as "napkin prototyping," as it allows for quick visualization of ideas.
Sketching is often used during the concept generation phase.
Common tools include pens, pencils, and tablets.
Sketching is a learnable skill and can be improved through practice.

Sketching Process

The sketching process consists of several steps:
- Define goals: Determine what you want to show, who your audience is, and the overall purpose of the sketch.
- Build a mental representation: Develop a clear mental image of the object or system you're sketching.
- Select a representation mode: Choose a sketching method that best suits your goals and the complexity of the design.
- Sketch: Draw the representation using the chosen tools and techniques.
- Validate: Review the sketch and ensure it accurately reflects your ideas and goals.

Sketching Goals

Concept sketch: Shows the overall idea or concept.
Function-oriented sketch: focuses on how the object or system works.
Design sketch: Emphasizes the aesthetics and visual aspects of the design.
Support sketch: Provides additional information about the design, such as dimensions or details.

Different Representations

Sketches can be used to create different representations of a design, including:
- 2D model: A flat representation of the design, as seen from a specific angle.
- 3D model: A representation of the design in three dimensions, allowing for more detailed visualization.
- Photorealistic rendering: A digitally created image that looks like a photograph of the design.

Sketching Circles & Ellipses

Circles: Can appear as ellipses in different projections, like isometric, cabinet, and orthogonal.
Techniques: Two approaches can be used:
- Outside to inside: Start with the outline and then refine it, adding detail as needed.
- Inside to outside: Start with the basic structure and then gradually build up the details.
