IB Design Technology 3.1 Conceptual Modelling Notes

Conceptual Modelling

1. A concept model is a way to represent an idea or design before making the actual product.
2. It helps designers think through their ideas, show them to others, and test different possibilities.
3. These models can be sketches, physical objects, or digital designs.

Types of Concept Models

1. Graphic Models
   1. These are 2D drawings or sketches that show what the design might look like.
   2. Example: Blueprints or rough sketches of a car design.
2. Physical Models
   1. These are 3D models made from materials like clay, wood, or plastic to test how the design looks and feels.
   2. Example: A small-scale model of a building.
3. CAD (Computer-Aided Design) Models
   1. These are 3D models made using software on a computer.
   2. They help designers test different designs without making physical versions.
   3. Example: A digital car design created in software like AutoCAD or SolidWorks.

Advantages of Concept Models

1. Lets clients give feedback – They can see the design and suggest changes.
2. Saves time and money – Testing ideas with a model is cheaper than making a full prototype.
3. Reduces errors – Helps spot problems before production.
4. Checks if parts fit together – Ensures components are the right size and shape.
5. Communicates function and looks – Helps explain how the design works and what it looks like.
6. Tests materials and methods – Can see what works best before full production.
7. Collects feedback – Designers, users, and clients can test and suggest improvements.
8. Used in user trials – Can check how people interact with the design.

Disadvantages of Concept Models

1. Might leave out details – Simple models may miss important parts.
2. Doesn’t always look like the final product – It’s just a rough idea, not the real thing.
3. Material differences – The model’s materials might not match the final design.
4. Scaled models may not show proportions well – A mini version of a product may not fully represent the actual size.
5. Not always durable – Some models break easily and can’t be used for long.
