Method & Evidence

AimHow can an integrated method combining Kansei Engineering and AI-generated content be used to design commercial vehicle body morphology that balances user emotional preferences with design efficiency?

MethodIntegrated methodological approach (AHP-SD-TOPSIS-AIGC)

ProcedureA Kansei evaluation system was built from literature and surveys. Hierarchical design indicators were established using AHP, with weights determined by consistency matrices. TOPSIS identified optimal style forms based on emotional coupling. Edge detection algorithms extracted symmetrical spline features for contour modeling. AIGC tools generated innovative solutions, which were then validated in truck design applications.

ContextCommercial vehicle body morphology design, new energy vehicles, emotional design frameworks.

Strengths & Limitations

Strengths

+Novel integration of Kansei Engineering with AI for vehicle design.
+Addresses both user-centric and process-efficiency aspects.
+Provides a validated methodological framework.

Limitations

The effectiveness of AI-generated designs depends heavily on the quality of the input data and the specific AI tools used. User preferences can be subjective and vary across different cultural contexts.

Reliability & validity

The study's validity is supported by the application of established methodologies like AHP and TOPSIS, and the validation through truck design applications. Reliability would depend on the consistency of user responses and the reproducibility of AI-generated outputs.

Think critically

To what extent can AI truly capture nuanced user emotions, or does it merely optimize for quantifiable aesthetic metrics? How might cultural differences influence the perception of symmetry in vehicle design?

Design Principles

"Balance aesthetic appeal with functional efficiency by leveraging established design principles like symmetry and modern generative design tools."

This research highlights how a fundamental design principle like symmetry can have a dual impact: enhancing user experience through aesthetic appeal and optimizing the technical aspects of product development. Designers can leverage this understanding to create vehicles that are not only visually pleasing but also more efficient to conceptualize and refine.

What This Means for Your Design

Making car bodies symmetrical makes them look better and helps designers work faster. This study shows how to use user feelings and AI to design cars that people like and are easy to develop.

How to use in your project

1.Reference this study when discussing the importance of form and aesthetics in your design project, particularly if symmetry is a consideration.
2.Use the findings to justify the inclusion of user emotional research (Kansei) in your design process.
