  • Planned Obsolescence: Cars

    Definition:

    “Planned obsolescence, or built-in obsolescence if you are in the UK, is the decision by a manufacturer to purposely design, manufacture and distribute a consumer product to become obsolete or non-functional specifically to force the customer to buy the next generation of the product.” (http://www.computerinfoweb.com/computer_electronics/Blu_Ray.php)

    Product: Cars

    A prevalent example of planned obsolescence in a product design is found in that of cars.

    Planned obsolecence in cars is a relatively new thing. In the sixties, cars that were manufactured before WWII were still driven, and during that time Volkswagen built a cheap and practical car “until it flooded the entire market”. However, companies realized that once sales stabilized, people would not buy new cars. For the manufacturers, this meant firing many workers and a drop in profits. Thus, for the next two or three decades they adopted the process of keeping manufacturers and workers busy and producing cars that would not last for a long period of time. Why? To keep customers buying new cars.

    The policy (regarding the production of cars):

    1. “routinely discontinue parts that could otherwise be made available for repairs.”

    2. ” confirm to a strict yearly cycle of model releases, often introducing purely cosmetic changes from one year to the next.”

    3. “retire popular models and bring out something new every few years, making it harder to fix older vehicles.” (instead of “sticking with hits and standardizing   them over time, which would better support a repair aftermarket”)

     

    Cars today, for many, are seen as a fashion accessory and statement. It has become common for people to buy the new model of a car, even if the one they own is in great shape, and still has years to live.

    Although planned obsolecence is beneficial for car companies, as it greatly increases their profits and product demand, one must consider the ethical implications of this policy. Is it ethically acceptable to produce cars that will not last very long in order to make a greater profit?

  • Snow Wovel

     

    http://www.wovel.com/

    Inventor: Mark Noonan

    Product Website: http://www.wovel.com/

     

    How does it work? 

    This product (a shovel on a wheel) is quite simple to use, but requires practice for some. The first step to take is to push the snow with the product, like pushing a stroller. Then, push the handle down to get rid of the snow wherever you please. The product must be assembled before it can be used.

    ** “A study at the University of Massachusetts found back strain from the Wovel is roughly akin to walking, reducing the risk of lower-back injury from shoveling snow by 85 percent.”

    Disadvantages: More expensive than a shovel, and must be assembled.

    Advantages: Ergonomic, convenient, and three times faster than a shovel.

    For those who live in snowy climates, this product proves very useful: it saves time, and most importantly it significantly reduces the risk of back-injuries, and related heart injuries.

  • Robot Lifeguard

    About:

    This robot was invented by inventor, entrepreneur and engineer Tony Mulligan. Named EMILY, an abbreviation of Emergency Integrated Lifesaving Lanyard, it “can swim through riptides at a speed of up to 24 miles per hour.” This makes it 15 times as fat as a human lifeguard, according to Mulligan.

    “It is powered with an electric pump that shoots a forceful stream of water”, and “has been tested at California’s Zuma Beach.” Lifeguards are in control of the robot, through a remote. The 2011 model features sonar technology and is controlled with an iPhone app, allowing it to detect riptides and people who have drowned.

     

    Reactions: 

    1. ” ‘From a technology perspective, [Emily] is quite innovative,’ says Howie Choset, a robotics professor at Carnegie Mellon University. ‘To be able to maneuver such a small craft through choppy waters straight to a drowning victim is incredible.’ ”

    2. ” ‘This is a classic example of an inventor’s idea of how to solve a problem that doesn’t necessarily coincide with reality,’ says B. Chris Brewster, president of the United States Lifesaving Association. He notes that a robotic floatation device — no matter how nifty — can’t save an unconscious swimmer.”

  • Thermoelectric Boots

    “Everything we do generates power — about 1 watt per breath, 70 watts per step.”

    Smart Material: Thermoelectric material.

    European telecommunications provider, Orange, introduced a prototype in 2010 of a pair of rubber boots that convert heat from your feet into electrical power. This electricity can be used to charge battery-powered handhelds, such as mobile phones. In order to charge the handheld’s battery to an hour, you must walk for 12 hours. This may seem long – running would make the process faster, as the more heat produced, the more electricity produced.

    They are a great sustainable, eco-friendly alternative to the vast amount of electrical power that is used everyday to charge battery-powered devices. They are also practical, because the electricity is produced from regular everyday activity.

    How the boots convert the heat into electricity:
