A Product Shape Design and Evaluation Model Based on Morphology Preference and Macroscopic Shape Information

Area of Science:

• Product Design
• Consumer Behavior
• Data Analysis

Background:

• Understanding consumer preferences is crucial for successful product design.
• Existing evaluation methods may not fully capture nuanced preferences.
• A systematic approach is needed to integrate design elements with consumer desires.

Purpose of the Study:

• To propose a novel product form design and evaluation model.
• To enable designers to effectively grasp consumer preferences.
• To validate the consistency and applicability of the proposed evaluation systems.

Main Methods:

• Deconstructing product forms into shape elements and creating a morphological chart.
• Prioritizing shape elements using the fuzzy analytical hierarchy process (FAHP).
• Evaluating selected combinations via fuzzy comprehensive evaluation (I), preference questionnaires (II), and quadratic curvature entropy (III).

Main Results:

• The fuzzy analytical hierarchy process successfully identified priority shape elements.
• Selected design combinations were systematically evaluated using three distinct sub-models.
• Analysis confirmed consistency across the fuzzy comprehensive evaluation, preference questionnaire, and quadratic curvature entropy methods.

Conclusions:

• The proposed product form design and evaluation model is applicable and effective.
• The three sub-evaluation systems demonstrate consistency, validating the model's reliability.
• This approach provides designers with a robust tool for aligning product forms with consumer preferences.
