Chapter 12: Problem 1

Disassemble one of the devices suggested below and put it back together. Sketch all the parts and illustrate how they fit together to make the device operate. List at least three ways you think the design could be improved. Choose one of the following devices: a) flashlight, b) lawn sprinkler, c) sink faucet, d) stapler, e) inkjet printer, f) computer mouse.

Short Answer

Expert verified
Answer: The flashlight was chosen for disassembly and analysis in the exercise. The three suggested improvements were 1) using more efficient LED bulbs for longer battery life and brighter light, 2) designing the switch to be more ergonomic and accessible for users, and 3) using an energy-saving mode for prolonged use.

Step by step solution

01

Choose the device

For this exercise, we will work with the flashlight as our chosen device.
02

Gather materials

Before beginning with the disassembly, make sure you have some paper and a pencil to sketch the parts, as well as a camera to take pictures of each step (if needed).
03

Disassemble the flashlight

Begin the disassembly process by unscrewing the cap at the end of the flashlight and removing the batteries. Next, carefully unscrew any other parts that hold the body of the flashlight together, making sure not to lose any small pieces such as screws, springs, and other parts. Lay out all the disassembled components in a systematic manner.
04

Sketch and label parts

Sketch each part of the flashlight on paper. Make sure to label each part with names and/or numbers, to help in understanding their function and placement later.
05

Analyze the function of each part and their connections

Examine each part and try to understand its purpose in the flashlight. For instance, the batteries provide power, the bulb emits light, and the switch turns the device on and off. Next, see how all the parts fit together. This can be done by analyzing how each part connects to the other and the order in which they need to be assembled.
06

Reassemble the flashlight

Using the sketches and pictures taken earlier, begin reassembling the flashlight by following the order of the disassembled parts. First, place the batteries into the body, followed by the switch and any other components. Lastly, screw the cap onto the end of the flashlight and test it to ensure it is functioning correctly.
07

Identify three possible improvements

After analyzing the flashlight's design, identify at least three ways in which it could be improved. For instance, 1) using more efficient LED bulbs for longer battery life and brighter light, 2) designing the switch to be more ergonomic and accessible for users, and 3) using an energy-saving mode for prolonged use.
08

Wrap-up

In completing this exercise, you have successfully disassembled, sketched, and reassembled a flashlight, while also identifying potential design improvements. Having a solid understanding of how a flashlight works and its components can provide valuable insights into designing a better, more efficient flashlight in the future.

Get together with three other classmates and brainstorm at least 30 ways to use one of the following objects: a) Two-foot length of string b) Ping-Pong ball c) One plastic soda bottle d) Page of notebook paper and a two-inch piece of tape e) 10,000 plastic grocery bags f) Obsolete cellphone g) Deck of playing cards h) Yo-yo i) Metal coat hanger j) Empty plastic milk container k) 15 paper clips l) \(1 \mathrm{lb}\) of rotting vegetables m) Newspaper and 12 inches of masking tape

Assemble a team of five students from your class and use the engineering design process to build a bridge that spans at least three feet between supports in contact with the ground. Materials: one roll of duct tape, 10 feet of rope, a 40 -inch by 75 -inch piece of cardboard, and 14 cardboard slats each 12 inches by 2 inches. After the design is complete, 40 minutes will be allowed for bridge construction and testing. The test: One of your team members must walk heel-to-toe across the bridge; extra points are awarded for spans exceeding three feet.

Assemble a team of four students from your class and use the engineering design process to build the tallest possible tower that can support a 12-oz can of soda/pop. Materials: one roll of masking tape, one package of straws, and one can of soda/pop. Constraints: Your tower must be freestanding and remain upright for five seconds under load to qualify for measurement. You have 30 minutes to complete this exercise.
