Milk Frother Pulled Apart

Author Date
  1. Prediction 
    1. Froth milk
    2. You put batteries in the back, hold the handle so the spindle end is in the milk, and flip the switch
    3. People just beginning the stationary part of their life
    4. Easily froth milk in a cheap and effective way 
    5. Poor affordance in the battery port
  2. Observation 
    1. I think you flip the switch and insert it in milk until the milk is aerated
    2. Good, except it splashes easily 
    3. It is definitely a no-frills design
    4.  Poor affordance in the battery port and that you shouldn’t put it in while it’s on 
  3. Test 
    1. Okay, it deflated fast and splashed in our faces
  4. Now consider your own device
    1. Straight up trash. It can’t go fast enough to froth milk without breaking, and we had to break to bottom piece bc it wouldn’t in the cup 
    2. Poor mapping in affordance bc it’s not clear where to hold it
    3. Strengths: it’s cool looking. Weaknesses: poor structural strength, mapping/ affordance, and too slow.
    4. Make it out of a strong material, make the spinner smaller, make it easier to hold
  5. Disassemble you IKEA device 
    1. The switch creates a circuit with the batteries. The electricity from the circuit traveled down the metal and copper prongs to the motor. That causes the motor to pull on the copper wires and spin the motor which is attached to the frother that spins around.
    2. It is made with plastic, metal, rubber, and whatever is in a battery
    3. 35 parts total
    4.  15 moving parts
  6. Analyze 
    1. Strengths: strong Weaknesses: very intricate 
    2. NA
    3. I’ve learned about all the components that go into a device
