Assistive Device for Mountaineer
On mountains ranging from 2600m to 4000m in height, the air pressure becomes lower than on the plain so that it’s possible to not only have acute mountain sickness but also to possibly die. We designed Reevesi to assist climbers to breath normally through lung expansion by lowering internal pressure, hence lowering the risk of HAPE. T e am Mem b er : Yu a n T i n g W a n g
Design Background Taiwan is a mountainous island. Climbers have plenty of chances to go mountain climbing. However, climbers tend to get acute mountain sickness (AMS). According to a study conducted by Yushan National Park, AMS is correlated with high altitude trekking experience. When the altitude is higher than 3000m, the AMS prevalence rates are 27%. Therefore, we wanted to design a product that would reduce the chances of climbers getting AMS.

pressure
and
increases
the
blood-flow rate. When vasoconstriction happens, water penetrates lungs easily.Those are vital factors to bring to HAPE.
Problem Solving Through principles of negative pressure ventilation, Reevesi compresses air pressure covering the chest which becomes negative while assiting the lungs expansion during inhalation. It can allow people to inhale more air, and get oxygen into the body. Because of this, it slows people’s breathing rate and solves the problem which increases mountain sickness.

Design Concept From the point of view of prevention, we hope to adjust the climber’s breathing rate throughout the whole process of climbing. The climber can inhale more oxygen actively from the air they’re breathing without using an oxygen cylinder.
Prototype In order to fit around a person’s chest and retain enough space to change the pressure inside, we tested, modified and redesigned the shape many times. With the coloured stripes, the device would match the clothing of the climbers, creating a sporty and functional design that is different from other mountain climbing equipment.
Mechanism design According to Boyle's law, the value dierences between pressure and volume have an inverse relationship in our product. If volume increases, then pressure decreases. Reevesi uses a motor controlled by our breathing movements to compress space and change the pressure value. Negative Pressure

Scenario The climber wears Reevesi outside of their base layers before climbing. After that they adjust the Reevesi for the perfect ďŹ t and buckle it. When the climber feels unwell on the road, they push the button and start the machine. It expels the air automatically by detecting the changes in breathing movement. Throughout the change in volume, Reevesi creates a space where is negative pressure so that reduces pressure and increase the inspiration capacity. It is an eective way to regulate breathing.

In Collaboration With
Travel Carriers For Pets
Product Story Traveling is a very exciting for dogs and we found that travel carriers are widely used. As pets spend lots of time in it; we designed iPet. It can be folded up and out fast according like a paper bag. iPet is not only just easy to carry and store, it is also comfortable and secure while dogs are being carried. It gives dog a comfort space to rest .The modern shape and well-designed detail of iPet let users Group Project
can travel with pets in style.

The Generic Laundering Process
Put underwear in bucket
Go to laundry room on roof
- Put underwear on washboard - Smear soap on it by hand - Wash it with clothes brush
Background My aunt suffers severe intellectual disability. Except

her
behavioral disability influences her daily life a lot.I wanted to improve her daily life to let her have more sense of accomplishment from the life.
- Didn’t know how to flatten underwear before washing it - Couldn’t swing arm out so that the brushing distance was shorter than others
