Research and Problem-Finding
For this week's assignment, I settled on a specific winter-related topic to research. I chose to explore thin ice and cold water safety, recalling the reports of drowning and hypothermia I hear every year. By conducting interviews, I learned about the experience of falling through ice and the physiological effects it has on the body. I sought out individuals who have fallen through ice or experienced hypothermia, have knowledge about winter safety, or have experience rescuing drowning victims.
Michael is a freshman at the University of Minnesota who
responded to my online search and volunteered to be interviewed. He has much
experience with falling through ice, having fallen into the pond at his
grandparents' house on ten different occasions. During childhood visits to
northern Wisconsin, he and his cousins would dare each other to run across a
semi-frozen pond. Someone, usually Michael, would break through the ice and
fall into the cold water. All the children would respond with laughter--including
the now shivering Michael. It was difficult for Michael to get out of the
water. The cold numbed his senses and his limbs. He tried to push himself up
onto the ice, only to break through again. He repeated this action, making a
path to the shore five or six feet away. After he had climbed out of the water,
the adults would run outside, yelling and fearing for his life. They brought
him inside, dried his clothes, and warmed him--scolding him all the while.
Michael recommended that anyone who falls through ice should
stay calm and regulate their breathing. He also emphasized the importance of
spreading one's weight across a large surface area when attempting to get back
onto the ice.
Laura is another student who volunteered to be interviewed. She
shared a story about her experience with mild hypothermia. Laura was swimming
at her family's cabin, not during the winter, but on a particularly cold
Memorial Day weekend. She, along with her brother and a friend, pulled a swim
raft into the lake. Laura's brother and friend mostly stayed on the raft, but
she swam to the bottom of the lake and spent more time in the water. Later the
trio was too cold to stay in the water, and the three made their way back to
the cabin. Laura's brother and friend quickly recovered from the cold, but she
was shivering uncontrollably for the next couple hours. She tried to recover by
drinking hot tea and sitting on a couch under a blanket but didn't feel much
better. She didn't fully warm up until taking a long, hot shower.
Laura recalls feeling lethargic and cold to her core.
Immediately after leaving the water, she wanted a way to quickly transfer heat
to her entire body, a need that she couldn't fulfill with what she had on hand.
Dr. Gordon Giesbrecht
Dr. Giesbrecht is a professor at the University of Manitoba who researches human response to extreme environments and has performed hundreds of cold water immersion studies. I used many resources from his website to learn about surviving a fall into cold water. I have contacted him but have yet to receive a reply. I hope to interview him via phone next week.
Kara Owens is the information officer of the Boat and Water Safety division of Minnesota's Department of Natural Resources. We've made contact, but she was unavailable for interview this weekend. We plan to meet next week, and I expect that she will have lots of relevant information. I've already used her Boat and Water Safety website as a research source.
I also contacted the University of Minnesota's Department of Emergency Management and a local snowmobile retailer asking about local winter safety problems and precautions. Both have yet to reply, but I hope to interview their staff members next week.
Designers make observations and conduct research to gather information about their topic of interest. Because it was impossible for me to observe people falling into freezing water, I focused heavily on researching my topic.
Two particularly useful resources were videos on Dr. Gordon Giesbrecht's website, titled "Getting That Sinking Feeling" and "Cold Water Survival." The first is extremely relevant to a product designer. It compares two snowmobile jackets, one that is more comfortable but absorbs water and another that is more expensive but drains water and is buoyant. The better-designed flotation suit, though less comfortable, is able to save a drowning victim. The second video shares specific techniques to climb out of freezing water.
I was also interested in Dr. Giesbrecht "1-10-1 Rule" of cold water immersion. For one minute, a victim in cold water gasps and hyperventilates involuntarily. To survive, he must calm down and concentrate on not drowning. Over the next 10 minutes, the victim loses effective use of his fingers, arms, and legs. Without a life jacket, he will drown. This is the critical time window in which the victim can potentially escape without outside assistance. He can survive for an additional one hour. After this time period, the victim will die of hypothermia. It is a misconception that hypothermia quickly kills victims within minutes.
Designers often take an empathetic approach to their topic, attempting to experience it for themselves. I didn't want to jump into a frozen body of water, but I did opt for a cold shower one morning.
Conclusions and Problem Statements
The goal of the interviews and research was to create problems statements to be contemplated later in the class. These are a few problem statements I constructed:
"Michael, a child who has fallen into an icy pond, needs a better way to get out of the water, because pushing vertically only further breaks the ice."
This problem was inspired by Michael's ineffectual attempts at getting himself on top of the ice. Dr. Giesbrecht also noted in his "Cold Water Survival" video that this technique is a common first response of a victim in cold water.
"Laura, a victim of hypothermia, needs a way to warm up her entire a body quickly, because simply insulating herself isn't stopping her uncontrollable shivering."
In my interview with Laura, she strongly emphasized her need to become warm quickly. She needed heat actively transferred to her body, rather than slowly contained by a blanket.
"Snowmobile enthusiasts need a way to see patches of open water, because their current headlights don't allow them to safely travel at night."
In Dr. Giesbrecht's "Getting That Sinking Feeling" video, a demonstration depicted snowmobiles plunging into water at night. It was stated that the riders should have slowed down so their headlights could illuminate the water. I wondered why the riders didn't simply have better headlights.Idea Wallet
The final portion of this assignment was to start an "idea wallet" and a "bug list." I have been recording interesting inventions, solutions, and oddities I encounter in my idea wallet to use as resources for future creations of my own. A bug list is the opposite. It contains all of the frustrations, glitches, and design flaws I notice every day. Below are two example entries from my week.
One frustration I've had recently was riding to class on a soggy and snow-covered bicycle seat. Some people create makeshift covers out of plastic bags, but I think it is reasonable to expect a better solution. Coincidentally, I also observed a clever idea that monopolizes on this problem. In the picture above, a local business created adjustable and formfitting bicycle seat covers and planted them on college students' bikes. In a brilliant advertising ploy, information about the business was spread and an entirely unrelated consumer need was fulfilled. I'm sure the positive experience created by the advertisement will leave a far more favorable and memorable impression than its direct message--all for virtually no cost.
