Hydraulics and pneumatics

Module 17

Design proposal for a pneumatic /hydraulic puppet

Problem situation

The younger patients of the Morningside Children’s Hospital are very depressed. It is not only because they suffer pain as a result of their illness, but also because nobody visits them to brighten up their day. Their families all live far away. The doctors and nurses observed this need and decided to build them a puppet theatre to brighten up their day and make them laugh again.

Design proposal

Use your knowledge of pneumatic and hydraulic systems as well as of mechanics to design and construct a character with a surprise element that can be used in the puppet theatre to brighten up the day of the younger patients.

Assignment 1:

[LO 1.3]

To analyse the situation

a) Identify the words that you do not understand. Discuss them with your teacher.

b) Briefly rewrite and describe the situation in your own words.

Assignment 2:

[LO 1.3]

To write a design proposal by completing the sentence:

Draft a design proposal by completing the following sentence. ( The design proposal is the possible solution to the problem.)

I am going to design and make a___________ (product/what) for____________

(user/who) that operates by way of a …(how) system, so that it has a

_________________________________ that will make a depressed person

_____________________when it is used in the puppet theatre (its function).

Research

In this module we have already been introduced to the way in which pneumatic and hydraulic systems work. If you wish, you can do further research. Write down any interesting information you might have. Also indicate the source you have consulted.

Assignment 4:

To brainstorm possible solutions to the problem

[LO 1.3]

Design and make :

Limitations / Specifications (the rules that must be followed)

  1. The material you have to use consists of two or three syringes, a plastic tube and a T-connection (if necessary) for the pneumatic or hydraulic system.
  2. The pneumatic/hydraulic system must not be visible to the audience.
  3. The character and its moving part/parts must be made from thick cardboard and held up by a round dowel stick. By pushing the plunger of the syringe in, or pulling it out, the required movement will be caused in the other syringe(s), which will cause the moving part to react as desired. The moving part may be joined to the static part by means of one or more rivets.
  4. The completed article must not be bigger than an A3 page.
  5. It must be completed within two hours
  6. It must be safe, because a child must also be able to handle it.
  7. It must look attractive and demonstrate the learner’s creativity.

Assignment 5:

Decide which of your solutions to Assignment 4 you would like to develop further, and indicate your choice by circling the solution you have chosen.

[LO1.3]

Assignment 6:

Draw freehand sketches of the front and back elevation of your chosen design

[LO 1.3]

  • Colour the front elevation to indicate what the final product should look like and give all the real dimensions and other relevant information.

Front elevation

Rear elevation

Assignment 7:

  • Which materials are you going to use? (See specifications.)
  • Which tools are you going to use?

[LO 1.3]

Assignment 8:

[LO 1.3]

Write down the steps you are going to follow under the following headings: (Use only one verb per sentence and write clearly)

[LO 1.3]

  • Measure
  • Shape
  • Join

Assignment 9:

Now make your own article

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
