Application

Design takeaway

How to apply

When developing new products, use AI image generation to explore a wide range of forms that align with brand guidelines. Simultaneously, analyze customer feedback to identify key emotional drivers and integrate these insights into the design requirements using a QFD framework.

Project actions

01When exploring product forms, consider using generative AI tools to quickly produce a variety of concepts.
02To understand user emotions, analyze customer reviews or conduct sentiment analysis on social media data related to similar products.

Method & Evidence

AimCan an AI-powered method integrating Shape Grammar and Kansei Engineering systematically design product forms that maintain Product Identity while addressing user emotional requirements?

MethodGenerative and quantitative design method

ProcedureThe method involves using Shape Grammar to generate initial product shapes based on existing product morphology and brand identity. These shapes are then refined using AI image generation tools (Midjourney) based on specific prompts. Concurrently, user emotional words are extracted from online reviews, clustered into Kansei factors, and weighted using Grey-AHP. These factors are then integrated with extracted product features into a Quality Function Deployment matrix, evaluated by experts to rank Product Identity Engineering Characteristics. Finally, designers refine the selected concepts into detailed 3D models.

ContextNew Product Development (NPD) for consumer products, specifically focusing on product form design.

Strengths & Limitations

Strengths

+Novel integration of AI, generative design, and established design research tools.
+Addresses a critical challenge in product development: balancing brand identity with user emotions.
+Provides a systematic and quantitative approach to subjective design aspects.

Limitations

The AI tools used might not fully capture the nuances of human emotion or brand identity without careful prompting and iterative refinement. The data collected from online reviews may not represent the entire user base.

Reliability & validity

The study's validity is supported by its systematic approach and empirical testing. Reliability could be enhanced by increasing the sample size for user surveys and ensuring consistency in expert panel selection and evaluation criteria.

Think critically

Consider the potential for AI to create designs that are emotionally appealing but lack genuine user benefit or long-term satisfaction. How can designers ensure that emotional resonance is coupled with functional excellence and ethical considerations?

Design Principles

"Product form design should be a synthesis of brand continuity and user emotional resonance, achievable through integrated generative and analytical methodologies."

This approach addresses the challenge of designing products that are not only aligned with brand identity but also resonate emotionally with users, a critical factor in today's competitive markets. By leveraging AI and structured methodologies, it offers a more systematic and efficient way to achieve this balance, reducing reliance on designer intuition alone.

What This Means for Your Design

This study shows how computers can help designers create products that look like they belong to a brand and also make customers feel good about them, by using AI to generate shapes and analyze feelings from reviews.

How to use in your project

1.This research can inform the ideation phase of your design project by suggesting methods for exploring diverse design concepts that meet specific criteria.
2.The use of AI for concept generation and Kansei Engineering for understanding user emotions can be referenced as advanced techniques for user research and ideation.
