Design Principles
"Select prototyping methods based on task-specific performance and efficiency metrics, favoring virtual methods when they offer significant advantages in speed and outcome quality."
This finding suggests that designers should strategically consider the benefits of virtual prototyping, particularly for iterative design and performance evaluation, to optimize project timelines and outcomes. Understanding when virtual methods are superior can lead to more efficient design processes and resource allocation.
What This Means for Your Design
For making things like mechanical joints, using computer simulations (virtual prototypes) is much faster and gives better results than building a real model (physical prototype). A tool can help you pick the right method, but it needs more testing to be sure.
