Application

Design takeaway

How to apply

When starting a new design project, create a matrix mapping your project's key objectives (e.g., testing form, function, user interaction) against available prototyping techniques, considering cost and time implications.

Project actions

01Explore various prototyping methods beyond just 3D printing, such as sketches, wireframes, and physical mock-ups.
02Clearly define what you want to learn from each prototype before you build it.

Method & Evidence

AimTo review and synthesize the state-of-the-art in design prototyping strategies, techniques, and guidelines for early-stage design development.

MethodLiterature Review

ProcedureThe authors conducted a critical review of literature sources from engineering, management, design science, and architecture, focusing on early-stage design prototyping. They synthesized insights on prototyping objectives, major techniques, relationships between techniques, and developed a strategy matrix. Exemplar prototypes from industrial design were also included.

ContextProduct, service, and systems development, with a focus on early-stage design.

Variables

IVPrototyping technique (e.g., paper prototype, CAD model, 3D print, physical mock-up)

DVDesign outcomes (e.g., clarity of concept, identification of usability issues, user feedback quality), Resource deployment (e.g., time, cost)

CVStage of design development, specific design problem being addressed, project objectives

Strengths & Limitations

Strengths

+Comprehensive review of a broad range of literature.
+Development of a strategy matrix to guide technique selection.

Limitations

The effectiveness of a technique can depend heavily on the specific design context and the skill of the designer. Not all techniques are equally accessible or affordable for student projects.

Reliability & validity

The reliability of the findings is supported by the systematic review of multiple literature sources. Validity is enhanced by the inclusion of exemplar industrial design prototypes and the development of a strategy matrix. However, as a review, it synthesizes existing research rather than conducting new empirical tests, which could introduce variability based on the original studies' methodologies.

Think critically

How does the 'state of the art' in prototyping evolve, and what emerging technologies might disrupt current best practices?

Design Principles

"The selection of prototyping techniques should be driven by specific project objectives and resource constraints, aiming to balance fidelity, cost, and time."

Effective prototyping is crucial for testing and refining design concepts before committing to expensive production methods. Understanding the spectrum of prototyping techniques allows designers to select the most appropriate methods for their specific project goals, thereby optimizing resource allocation and increasing the likelihood of a successful product launch.

What This Means for Your Design

Using different ways to make early models of your design can save money and make your final product better.

How to use in your project

1.Use this research to justify your choice of prototyping methods in your design process. Explain why you chose certain techniques over others based on your project's goals and constraints.

Paragraph starter

The selection of appropriate prototyping methods is critical for efficient design development and project success, as highlighted by Camburn et al. (2017). Early-stage prototyping, utilizing techniques that balance fidelity with cost and time, allows for iterative testing and refinement of design concepts. This approach minimizes resource expenditure and maximizes the potential for a successful final product by enabling designers to identify and address issues before significant investment.
