Graphical Modelling
Which drawing type is used to explore forms and possibilities in the early stages?
Sketching
MISCON: What is the difference between Aesthetic Prototype and a Mock-Up?
Aesthetic Prototype focuses on look and feel, while a Mock-Up is a full size model showing form and layout, to test design concepts
List all the types of virtual prototyping
Surface & Solid, Generative Design, Digital humans, Motion capture, Haptic technology, Virtual reality & Augmented reality
What is one advantage of a low fidelity prototype?
Quick and inexpensive to produce
Encourages experimentation and iteration
Facilitates early user testing and feedback
What does SLS stand for?
Selective laser sintering
What are 3 formal drawings?
Assembly, Orthographic and Exploded
Difference between function and performance prototype?
A function prototype is a prototype that helps designers test how the product works, while a performance prototype tests how well a product meets its intended value
Define haptic technology
A technology that enables the user to interface with simulated touch sense via a haptic device
What is 2 examples of a material used for a prototype?
cardboard, plastic, or 3D printing.
Which is the most cost-effective 3D printing method?
Fused Deposition Modelling (FDM)
What are the 3 differences between sketching and assembly drawings?
- sketching is informal/assembly is formal
- sketching audience is designers themselves/assembly is for manufacturing
- sketching is quick/assembly takes time
(possible other sketching not very precise/assembly is a clear representation)
What is the point of doing a material prototype?
To find suitable materials for a product based on durability, weight, texture, and how the materials interact with each other.
What is the name of this type of prototyping?
uses Al algorithms in CAD to explore a wide array of design options based on constraints (e.g., materials, weight). This technology can enable the discovery of innovative solutions that optimize performance and efficiency.
Generative design
What prototype is effective for presenting to stakeholders?
High fidelity
Which 3D printer uses a laser to cure resin into solid plastic?
Stereolithography
What are the 2 disadvantages of Orthographic projection?
limited perspective and interpretation difficulty
What is the point of Physical Prototypes?
To test ideas and gather insights that inform and aid the development of the product.
What is the importance of FEA in design (at least 2)
Risk Reduction, Design Optimization, Performance Prediction, Cost Efficiency
What is a middle fidelity prototype?
communicate more about an idea or concept. They may communicate some but not all of the functions of the design.
Which 3D printer is used to make complex geometries?
Selective laser sintering (SLS)
How is an exploded drawing presented?
show the relationship between the various parts of an assembly, depicts parts slightly apart.
What are the two types of scale prototypes?
Full-scale prototypes and scaled-down models.
What model can be used to create FEA
Solid models
place in order and describe; Final Validation, Refinement, Concept exploration
:Concept Exploration: Designers might start with quick sketches and rough cardboard or foam models to explore overall form and basic functionality.
Refinement: As concepts are narrowed down, teams may create more detailed 3D printed models or CNC-machined prototypes to test specific features and ergonomics.
Final Validation: Highly refined prototypes using near-final materials and manufacturing processes are created to validate the design before full production.
One pro and one con of Stereolithography
pros: high precision, smooth surface finish,
cons: material limitations, post-processing requirements
