Sustainable Mobile Automated Car Wash

Project Overview

In this innovative design project, I contributed significantly to the development of a sustainable, mobile automated car wash, specifically leading the design and material selection of the drying system and protective cover. Our team aimed to create an environmentally friendly, portable car wash solution addressing the high operational and land costs prevalent in the European market. My responsibilities focused on selecting optimal materials and designing components to ensure operational efficiency, reliability, cost-effectiveness, and environmental sustainability.

Objectives

• Design and develop an effective, energy-efficient drying system for a mobile, automated car wash
• Select optimal materials for a retractable protective cover, balancing durability, portability, and environmental sustainability
• Analyze various materials based on criteria including UV resistance, chemical resistance, durability, portability, heat resistance, and water resistance
• Provide technical justification for each material and design decision based on extensive research and industry best practices

Methodology

Dryer System Design and Development

• Investigated various drying technologies, selecting a touchless drying system using high-performance axial fans for efficiency and reduced risk of vehicle damage
• Evaluated motor specifications (10hp vs. 15hp), ultimately selecting a 10hp motor (170 mph airflow) for optimal balance between drying effectiveness, lower power consumption, and operational cost savings
• Designed an intuitive arrangement of axial fans with polymer nozzles strategically placed to maximize drying efficiency while maintaining low energy usage

Cover Material Selection

• Conducted extensive material analysis (polyethylene, polypropylene, acrylic, fiberglass, and aluminium) evaluating UV resistance, chemical resilience, durability, heat resistance, water resistance, and portability
• Selected polypropylene as the final material, scoring highest overall (26/35), offering superior mechanical properties, excellent chemical and UV resistance, and outstanding durability despite its higher initial cost
• Partnered with Stuart Canvas, a specialist provider of retractable tunnel covers, leveraging their expertise to customize the cover's dimensions, mechanism, and aesthetics aligning with the brand identity and practical needs

Key Innovations and Results

• Implemented a fully touchless drying system utilizing axial fan technology, optimizing airflow (170 mph) to significantly reduce drying times and power consumption
• Successfully developed a robust, aesthetically appealing, retractable polypropylene cover ensuring operational safety and environmental containment
• Established a replicable and scalable methodology for future material selection and system optimization
• Delivered significant environmental impact reduction through energy-efficient design and sustainable material selection
