Overview

This MMA4002 Design for Automated Manufacturing group project developed a 3D-printed underwater sampling container system for ROV-based marine research. The design features pressure-resistant containers with customizable sizes, three different clip mechanisms (magnet, twist, slide), and a universal bracket system. The project applied Industry 4.0/5.0 principles, Design for Automated Assembly (DFAA), and Lean Manufacturing concepts, with final assembly performed by collaborative robots.

Problem Statement

Design a customizable, pressure-resistant container system for underwater sample collection that can be automatically manufactured via 3D printing and assembled by collaborative robots, while meeting diverse customer specifications for size, depth rating, and attachment mechanism.

Challenges & Solutions

Challenge Solution Outcome
Pressure Resistance Design Calculated wall thickness based on depth requirements and material properties (PETG) Containers rated for various ocean depths with appropriate safety factors
Automated Assembly Optimization Applied DFAA principles to minimize parts and simplify assembly directions Robot-friendly design suitable for cobot assembly
Modular Product Architecture Designed interchangeable clips and universal bracket system Product family with three container sizes and three clip variants
