Project Overview

This week's assignment focused on learning computer-aided design (CAD) principles and creating a parametric 3D model. The project involved designing a 3D Genji Ko representation of 6 difference incense sequences using 3D modeling software and documenting the entire design process.

Historical Context: Genji Mon Pattern

The Genji Mon (源氏紋) is a traditional Japanese family crest pattern with deep historical significance. The pattern represents the Genji clan, one of the most influential families in Japanese history, particularly during the Heian period (794-1185). Historical Significance: • Origins: The Genji Mon pattern dates back to the Heian period and is associated with the Minamoto clan (源氏)
• Cultural Impact: Featured prominently in "The Tale of Genji" (源氏物語), considered the world's first novel
• Design Elements: The pattern typically features geometric arrangements representing different aspects of court life
• Modern Usage: Still used in traditional Japanese arts, textiles, and ceremonial contexts
Pattern Characteristics: • Geometric Structure: Based on traditional Japanese geometric principles
• Symmetry: Highly symmetrical design reflecting balance and harmony
• Cultural Symbolism: Each element carries specific cultural meaning
• Artistic Tradition: Part of Japan's rich textile and design heritage

Design Files

• geniji-mon-3D.step - 3D parametric model of Genji Mon family crest
    STEP format for maximum CAD compatibility and manufacturing readiness
Design Process: 1. Research Phase: Studied traditional Genji Ko designs and geometric principles 2. Sketching: Created initial 2D sketches to establish proportions and layout based on traditional design 3. 3D Modeling: Used parametric design methodology 4. Refinement: Iteratively refined the design based on geometric principles 5. Export: Saved in STEP format for maximum compatibility

Learning Outcomes

CAD Skills Developed: • Parametric Modeling: Learned to use constraints and relationships in 3D design • Geometric Construction: Applied traditional design principles to modern CAD • File Formats: Understood the importance of STEP format for interoperability • Design Documentation: Practiced documenting the design process Challenges and Solutions: 1. Challenge: Maintaining symmetry in complex geometric patterns
    Solution: Used parametric constraints and mirroring operations 2. Challenge: Translating 2D traditional design to 3D model
    Solution: Extruded 2D profiles and used boolean operations

Software and Tools Used

• Primary CAD Software: Fusion360 • File Conversion: STEP export functionality • Documentation: Markdown for process documentation • Image Compression: Online compress JPEG tool

Future Applications

This 3D model serves as a foundation for: • Digital Fabrication: Can be 3D printed or laser cutted

Final Project Concept: 3D Incense Diffuser

Building on the Genji Mon pattern design, I'm developing a concept for my final project - a 3D incense diffuser that incorporates the traditional geometric patterns into a functional object. Project Vision: • Cultural Integration: Combining traditional Japanese design with modern 3D printing technology
• Functional Art: Creating a beautiful object that serves a practical purpose
• Pattern Application: Using the Genji Mon geometry to create ventilation and aesthetic features
• Material Exploration: Testing different materials (resin, ABS) for optimal functionality
Design Considerations: • Ventilation: Genji Mon pattern provides natural airflow for incense diffusion
• Heat Management: Material selection for heat resistance and safety
• Aesthetic Appeal: Traditional patterns create visual interest and cultural connection
• Manufacturability: 3D printing allows for complex geometries impossible with traditional methods

This week was an introduction to the course structure and the beginning of learning computer-aided design. I'm excited to explore the possibilities of digital fabrication and parametric design.
