Design Process • Project Management • Determination of Customer Needs and Definition of Problem • Concept Generation • Final Concept Selection • Initial Design and Assessment • Final Design • Analysis
Problem Statement We, Team Craftsman, are aiming to produce a design for drying clothes effectively in a solar-powered, aesthetically pleasing manner. Our design must compensate for changes in weather condition in the Central Pennsylvania area. Also, our design must be kept eco-friendly, meaning it may not use excessive amounts of energy, nor pollute the environment in any way.
Concept Selection • Main Criteria: • Safety • Cost • Durability • Drying Ability • Capacity
Assembly • Attach four side walls in a rectangle formation. • Fasten solar panel to roof. • Secure roof to side walls. • Attach door to back wall. • Insert heater and fan system in bottom of dryer structure. • Place grate on top of heater/fan structure. • Secure rubber mat on top of grate. • Insert two hanging racks horizontally in dryer structure. • Attach ringer system to outside of dryer structure. • Wire solar panel to heater/fan system.
Design Calculations Standard Clothes Dryer - 833,000 watts per year drying clothes in a typical American family using a standard clothes dryer 119,154 watts per year absorbed by a solar powered dryer 100W per minute to dry clothes * 60 minutes to dry the clothes (6.03 kwh to dry clothes) = 6000W per cycle 6000W * 4.7 loads a week = 28200 watts per year 119,154 watts per year absorbed by a solar powered dryer – 28200 watts per year drying clothes = 90,954 Watts saved using a solar powered dryer
Analysis • Cost efficient and durable materials – determined using material selection charts - aluminum alloy and nickel - plastic and rubber • Retail price at approximately $1999.99
Conclusion Team Craftsman has engineered this dryer to meet the customer’s energy efficiency needs as well as maintaining a stable and thorough drying of the clothes. We have incorporated heat and air flow, the basics of drying, into our design in such a way that does not rapidly increase the user’s carbon footprint. Our large chamber with low-watt fans and vents creates the perfect atmosphere for air to course through the Eco-dryer 1500, drying the clothes rapidly.
