SENIOR ADVANCED DESIGN PROJECT Cooling humidifier umbrella for lung cancer and multiple sclerosis patients Presented by Christopher R Aitken, Christopher J Barry, Jaime Martinez Diaz, Jason J Schwarzwalder, Yizhe Wang, Yunke Chen 1
The problem ● Approximately 300, 000 people are living with multiple sclerosis in the US [1] ● Approximately 500, 000 people that are currently living have been diagnosed at some point in their life with lung cancer in the US [2] ● These diseases cause breathing ailments that can dictate people's lives 2
Overall Goals ● ● Easy to use Keep the user cool underneath Implement Solar panels Light weight 3
Cooling System Background information: ● Source of Humidity and Heat [3] ○ ○ Humidity ■ Humidity is the amount of water molecules in the air ■ Relative humidity is the amount of water molecules in air versus the amount of water the air can hold at a given temperature The sun emits different kinds of electromagnetic radiation ■ 99% of the radiation being ultraviolet rays and infrared rays ■ UV- B and UV-C are not filtered through the Ozone layer ■ Infrared radiation being the source of the heat 4
Cooling system ● Evaporative Cooling[4] ○ ○ Evaporating water leaves behind a cooler temperature Increases the humidity Best for areas with high temperature and low humidity Typical application: ■ Evaporative pad that lowers temperature ■ Fan intakes air through the pad and distributes cooler air ● Reflective Material ○ ○ Prevent absorption of heat by the umbrella Aluminum is able to reflect UV rays and is relatively cheap 5

Cooling System - Components Ultrasonic Atomizer[6]: Comidox Ultrasonic Mist Maker Voltage: DC 5 V Outer diameter: 20 mm Current 300 m. A Atomization speed: 60 - 120 m. L/H Price: $1. 70 10
Cooling System - Components Water Pump[7]: Vipe water pump DC Voltage: 2. 5 -6 V Size: 45 mm x 24 mm x 33 mm Maximum lift: 40 -110 cm Flow rate: 80 -120 L/H Price: $2. 99 11
Humidity and Temperature Detection $9. 95 DHT 22 (AM 2302) [8][9] Measures temperature and humidity Compatible with the Raspberry Pi Works within -40 to 80°C ± 0. 5°C (-40 to 176°F) Works within 0 -100% Humidity 2 -5% accuracy Runs on 3 -5 v 27 mm x 59 mm x 13. 5 mm 12
Data Receiving and System Control Extremely cheap $5 Raspberry Pi Zero [10] Designed for ease of use Vast amount of tutorials Flexible with possible applications Runs on 3. 3 v 65 mm x 31 mm x 5 mm 13
Solar Panels How they work: Silicon material composed of several photovoltaic cells Photons from the sun’s rays hit photovoltaic cells, exciting the electrons, knocking them free of their atoms 14
Primary choice: Uxcell’s Mini Solar Cells [11] Polycrystalline silicon material 5 V, 60 m. A, 50 mm x 43 mm, 36 g 15
Its use in the umbrella: Use several small solar panels Located on the outside of the umbrella canopy Primary source of power to the circuit Connected in parallel Waterproof 16
Alternative choice: JIANG’s Flexible Solar Panel [12] 6 V, 160 m. A, 195 mm x 80 mm, 27 g Could be more convenient for folding the umbrella canopy 17
Primary Battery: Samsung 20 S 18650 Lithium ion battery[13] 2000 m. Ah capacity, 60 A continuous discharge rating, 3. 6 nominal voltage, 65 mm (length) x 18. 44 mm (diameter), 48 g “Backup” power when solar panels can’t supply enough voltage High energy density Can be swapped out to avoid case of umbrella shutting down 18
Alternative choice: Bonai AA Ni-MH Battery[14] 2800 m. Ah capacity, 1. 2 volts, 50. 5 mm (length) x 14. 5 mm (diameter), 26 g Less energy density Takes up more space Safer for charging from solar panels 19
Diode Circuit Acts as a voltage comparator to determine whether the solar panels or battery power the umbrella Current-limiting regulator will prevent the solar panels from overcharging the battery to prevent an damage 20
Umbrella Construction ● Three main factors of choosing umbrella frame ○ Durability ○ Stability ○ Integrate friendly 21
Umbrella Construction ● Primary choice: ○ Bubble Umbrella[15]: ■ Durability ● 3. 0 mm fiberglass ribs ● 8 stainless steel support ribs ■ Superior windproof ● Wind-Resistant frame ● Up to 51’’ canopy size ■ Lightweight construction ● 14 mm aluminum central pole ■ Clear canopy ● Not UV proof 22
Umbrella Construction ● Alternative choice: ○ Double Canopy Umbrella[16]: ■ Durability ● 3. 0 mm fiberglass ribs ● 8 stainless Steel Support Ribs ■ Superior UV-proof and windproof ● SPF 50+ protection ● Double-canopies design ■ “Heavy duty” ● Golf Umbrella ● Up to 68 -inch canopy 23
Umbrella Construction ● The way to assemble umbrella with other components: ○ 3 D prints ■ Software: Cura ● Free use on campus ■ Filament: Polylactic acid(PLA) ● Food safe material ● Friendly for patients ● High melting point 24
Umbrella Construction Expected part needed to be 3 D printed: ● ● Ferrule Water container to umbrella base Mounts for sensors Fan blades 25
