Physical Prototypes
Physical Prototype
A tangible, real-world model of a product, built using physical materials.
They can be aesthetic (how it looks) or functional (how it works), depending on the design stage and purpose.
Why Build Physical Prototypes?
- Helps Others Understand the Design
- Tests Scale and Space
- Reveals Practical Issues (identify flaws in comfort, interaction etc.)
- Supports Iteration
The fidelity of your prototype (how realistic or detailed it is) should match its purpose. For more on fidelity levels, refer back to Section 2.1.13.
Key Considerations in Prototyping
1 - Scale
- The size of the prototype relative to the final product.
- Considerations:
- Full-scale prototypes: Provide accurate insights into ergonomics and functionality.
- Scaled-down models: Useful for large products (e.g., buildings) to test overall design and spatial relationships.
Always consider the context in which the prototype will be used. A full-scale model may be necessary for testing ergonomics, while a scaled-down version might suffice for visualising overall form.
2 - Shape
- The geometric form of the prototype.
- Considerations:
- Ensure the shape accurately represents the intended design.
- Test how the shape affects functionality, aesthetics, and user interaction.
Shape is not just about aesthetics, it can significantly impact a product's functionality and user experience.
3 - Space
- The relationship between the prototype and its environment.
- Considerations:
- Test how the prototype fits within its intended space (e.g., a chair in a room).
- Evaluate how it interacts with other objects or systems.
Think of a prototype as a dress rehearsal for a play. It allows designers to test and refine their ideas before the final performance, ensuring everything works as intended.
