01Dimensional analysis can be applied to conceptual design for objective evaluation.
02A metamodel framework can integrate generic concepts and rules to guide concept generation and evaluation.
03Transforming a classification structure into a metric space allows for comparable analysis of design concepts.

Application

Design takeaway

Integrate principles of dimensional analysis and metamodelling into your conceptual design workflow to create a more robust and objective evaluation system for design concepts.

How to apply

When evaluating multiple conceptual solutions, identify key functional parameters, derive dimensionless numbers that represent their performance, and use these numbers to compare and rank the concepts.

Project actions

01Clearly define the core functions of your design.
02Identify relevant physical quantities and their dimensions.
03Explore analogies to simplify complex relationships.

Method & Evidence

AimTo develop a conceptual design methodology that utilizes dimensional analysis and dimensionless numbers for improved evaluation and comparison of design solutions.

MethodMetamodelling framework based on General Design Theory (GDT), incorporating analogies and dimensionless numbers.

ProcedureFormalize customer needs, generate design concepts considering the product life cycle, and evaluate concepts using a metamodel that transforms classifications into a metric space through clustering and rule-based conditions.

ContextConceptual design process, product development.

Variables

IVApplication of dimensional analysis and metamodelling principles.

DVRigor and comparability of conceptual design evaluation.

CVFormalized customer needs, life cycle considerations, generic design concepts and rules.

Strengths & Limitations

Strengths

+Provides a systematic and quantitative approach to conceptual design evaluation.
+Integrates life cycle thinking early in the design process.

Limitations

It can be challenging to identify appropriate analogies or to successfully create a metric space from qualitative design attributes.

Reliability & validity

Reliability would be enhanced by clearly defined rules for deriving dimensionless numbers. Validity hinges on the chosen analogies accurately representing the functional relationships and the metric space effectively capturing comparable aspects of the solutions.

Think critically

How might the subjectivity of selecting 'analogies' impact the objectivity of the dimensionless numbers derived?

Design Principles

"Evaluate design concepts using dimensionless metrics derived from functional requirements and life cycle considerations to ensure comparability and rigor."

This approach moves beyond subjective comparisons in early-stage design by providing a quantitative framework. It enables designers to systematically assess and refine concepts, ensuring they align with functional requirements and consider the entire product life cycle from the outset.

What This Means for Your Design

Think of comparing different car designs. Instead of just saying one looks better, this method helps you use numbers to see which one is more efficient or safer based on its core functions and how it will be used over its lifetime.

How to use in your project

1.Reference this method when discussing the evaluation and selection of design concepts in your design project report.
2.Explain how you adapted dimensional analysis or metamodelling principles to compare your design alternatives.

Paragraph starter

The selection of design concepts was guided by principles of dimensional analysis, as proposed by Coatanéa (2005). This involved formalizing customer needs and evaluating potential solutions using a metamodel framework that transforms functional requirements into comparable metrics, ensuring a rigorous and objective assessment of design alternatives against life cycle considerations.
