Interdisciplinary Unit- Research

Section One: Research Sept.18th 2013

By: Rachael Pye

My machine: How it works what it will look like the materials I will use and the basic scientific principles, which are behind it:

My machine is going to be called the Egg Decapitator. It will cut the top off a HOT soft boiled egg, so you can dip your toast into the egg to eat the yolk.  Currently you have to use a knife and hold the hot egg, which burns your fingers.

It will have a piece of wood that is held vertically upright by a wooden stand. There will be a hole in the wood for the egg to lie in. A cradle will hold the egg, lying down with its top sticking out of the hole. There will be a lever connected to the blade at the top of the main frame and when the fixed straight piece of wood which is the lever is pushed in the center the blade connected to the lever is then going to swing down, it will swing down and cut the egg. “A lever is a simple machine used to gain force, gain speed, or change direction. Crowbars, seesaws, wrenches, wheelbarrows, nutcrackers, hammers, bats, balance scales, and thousands of other things in common use are levers or combinations of levers. Arms, legs, hands, feet, and other parts of the body are also levers.” A lever is a fixed object in a straight line with a pivot in either the center, right or left. There is a class 1 lever, a class 2 lever and a class 3 lever. The three levers vary; the class one lever has a pivot in the middle of the fixed rod the load on the left and the force on the right. The class 2 lever has the pivot on the right hand side and the load in the middle and the effort on the left hand side. The class 3 lever has the pivot on the left hand side the load on the right and the effort in the middle.

The class of lever that I am going to be using for the egg decapitator is going to be the class three lever. This is because when I want the blade to swing down I can push the middle of the fixed rod of the lever and then the blade (which will be connected with a nut and a bolt) to the right on the fixed rod it will come down on the egg and cut off the top of it, it will allow this and it will work the best with my machine. I will have the lever situated on the back of my machine. The lever will have a load which will be the blade secured onto the fixed rod with a nut and bolt, this will allow the blade to swing when I push it down in the middle. Then the blade will swing down and cut the eggs top off. Refer to the picture below:

The materials I will need to make this machine are as follows;

1.   Wood.

2. A blade.

3. A leaver.

4. A stand to keep the machine upright.

5. A cradle to hold the egg.

The lever I am going to be using is a class 3 lever.

The need my machine will meet is:

It will allow you to cut off the top of your soft boiled egg without burning your fingers whilst trying to cut off the top of the soft boiled egg with a knife.

My idea

I came up with this idea when I was finished cooking a soft boiled egg and was becoming very frustrated when trying to cut the top of it off to eat the yolk and kept burning my fingers. So I thought that it would be a good idea to make a simple machine that took off the top of the egg without you burning your fingers. 

The front view of my machine:

The rear view of my machine

Screen Shot 2013-09-24 at 4.56.49 PM

The triangle is the fulcrum, the force is in the middle and the blade then swings down and cuts the eggs top off.

Dimensions = the height of the machine is going to be 15 centimetres. The width is going to be 12 centimetres and the depth is going to be 1 centimetres.

My specific client or group: That I want to be able to consume my machine are housewives or househusbands because they mostly are the ones who stay at home and cook. So therefore whenever they are cooking eggs they can use this machine.

These people would like this machine because they currently burn their fingers when trying to take off the top of their egg  and this machine prevents you from doing this.Why i think they would use this machine is because it is a quick, effective and practical machine to use. it will be quite cheap to produce so therefore in shops they will be able to sell this cheaply also. Most people will therefore be able to afford it and it is extremely easy to use and will come with instructions so anybody will be able to use it.       

The people who will be benefiting economically from my machine are:

  • The workers who build the machine by getting a salary.
  • I would pay them 15 euros per hour they worked.
  • I would need roughly 20 people to make the machine so it could be mass produced. But of course it depends on how big the factory is.
  •  The supermarkets/shops who make a profit from selling the machine.
  • They would get the profit of whatever price they decide to sell my machine at.
  • I would sell the machine to my clients for between 5-10 euros because this would give me good profit.
  • The suppliers of the raw materials from whom I will buy my raw materials.
  • They will make profit from me buying my materials from them but i will pay no more than 3 euro for the wood blade and plastic per machine.
  • My machine is going to be built in a factory.  The people who own the factory are going to be receiving my rent every month so they will be receiving roughly 5000 euro a month as profit.

The people who will lose economically are the people who buy the machine because the machine will cost them money.

The resources that will be needed are the following:

1.   Wood

2. A blade.

3. A leaver.

4. A stand to keep the machine upright.

5. A plastic cradle to hold the egg.

The machine will be sustainable or not sustainable and will need the following resources:

1. Wood

2. A lever

3. A metal blade.

4. Plastic to make the cradle

5. A stand to hold the machine upright

These resources are easy enough to come by.  They will be sustainable because:

1. The wood for the machine from a company who will replant three trees every time they cut down one,

2.  The metal will be sustainable because we will use recycled metal

3. The plastic I am going to use is going to be recycled plastic, so therefore this will be a sustainable resource. Plastic is still bad for the environment though.

My focus group questionnaire: 

Questionnaire

1.  How large/small would you like the machine to be for your storage space?

Douglas: I would like the machine to be small so I can fit it into my cupboard.

Louise: as small as possible, no bigger than 20 centimetres

2. How much would you like this machine to cost?

Douglas: I would not like the machine to cost more than 10 euros

Louise: as cheap as possible no more than 15 euros.

3. Who do you think will buy this product?

Douglas: I think that house wives and people who like boiled eggs will buy this product.

Louise: I think people who like eggs for breakfast will buy this product

4. Do you like the idea of my product?

Douglas: yes I do like the idea of your product.

Louise: yes I do

5. How do you think I can improve my product?

Douglas: I think that you can improve your product by making the depth thicker.

Louise: I think it would help if the blade had a cover over it for safety sake.

6. Would you prefer the blade to be very sharp or more blunt on the machine?

Douglas: very sharp and serrated.

Louise: very sharp.

7. How would you like the machine to look (painted/not painted)

Douglas: painted in funky colours

Louise: painted

8. what else do you think this machine could be used for ?

Douglas : chopping fingers off naughty kids and chopping up carrots.

Louise: chopping the tops/bottoms off carrots beans ECT.

9. How much maintenance would you be willing to put up with (some/none)?

Douglas: none

Louise: none

10. Would you buy this product?

Douglas : yes

Louise: yes

My focus group is my: mother Louise and my Father My Douglas.

Future problems I may come across:

1. Blunt: The blade could become blunt and not sharp enough to cut the egg.

2. Chip: The paint/wood could chip.

3. Size: The hole may not be small enough so that only the small front of the egg fits into the hole and the whole egg falls through.

4. Fixtures: The lever or stand could fall off the main piece of wood.

5. Cost: The cost to make the machine could be far too much.

6. Weight: The machine could be too heavy for the stand

7. Toxicity: If any of the machines parts are toxic this could kill/harm the consumer.

8.Getting burnt: If you get burnt positioning the egg into the cradle this could be a problem.

9. Time consuming: If my machine is too time consuming and not worthwhile using this could be a problem.  

10: Cleanliness: If the machine is not easy to clean bits of egg could get stuck on it which could start to rot.

11: Cutting the egg: If the top of the egg doesn’t come off. This is going to be a problem.

The solutions for Future problems I may come across:

1. Blunt: I would have to re sharpen the blade.

2. Chip: I should varnish the paint /wood.

3. Size: I would have to re measure the size of the egg and figure out the size the hole should be.

4. Fixtures:  I must make the lever very well secured. I would have to make sure that the stand is firmly super glued on.

5. Cost: I would have to either change my suppliers or find cheaper alternative materials.

6.Weight: I would reduce the weight of the wood or use a different type of wood.

7. Toxicity: I would have make sure that before I use any materials for my machine I have to make sure that they are not toxic.

8. Getting burnt:  I will supply clear instructions with the machine therefore you will know how to use it. I may also need to consider designing a ridge onto the end of my cradle to keep the egg in position.

9. Time consuming: I would have to make the machine less complicated to manage or use so I would have to make the machine more simple to use.

10: Cleanliness: My machine must be easy to clean.

11: Cutting the egg: I will have to make sure the blade is sharp enough so it can actually cut the egg.

Three inspiring machines that inspired me to make my machine

Screen Shot 2013-09-25 at 2.55.37 PM

This is a machine called a Guillotine. This machine was invented to during the French revolution and was used to behead people if they were rising up against the king or the queen of France at the time during the french revolution. It was used to behead people during the French Revolution.it was a gruesome machine used for public executions. people at the time enjoyed watching these sorts of things.

When you pull the blade up using a pulley you inserted the person’s head into the hole at the bottom and then you let go of the rope and the person who’s head is in the hole gets chopped off. The last time the guillotine was used was on September 10th 1977 when “torture-murderer Hamida Djandoubi was executed”. it was a gruesome machine used for

This is a machine called EZCracker, which is a machine that cracks eggs.  If you also would like it to it can separate the eggs yolk and the eggs white.

Screen Shot 2013-09-25 at 3.43.31 PM

This is a machine that cracks the top of a boiled eggs shell. You turn the crank, which moves the gears, which moves the spoon on the end up and down hitting the top of the boiled egg and cracking the top of its shell.

Pulleys being used in the guillotine:

The guillotine has not got the same mechanisms as my machine will have, but in fact it uses a pulley instead of a lever. They used a pulley to pull the blade up on a rope and then they inserted the persons head into the hole and let go of the rope and there head would be cut off.

Screen Shot 2013-09-25 at 3.49.20 PM

 This is a picture of the guillotine in use.

http://www.debate.org/opinions/should-we-use-the-guillotine-to-execute-people

The guillotine has been effective/ ineffective in ways.

It was affective In that:

1. It did decapitate people

2. It created a gory show for people to watch.

3. It stopped people from wanting to break the law because they then knew that they would be beheaded.

 It was ineffective in that:

1. It did behead people but not always on the first go. This happened and was bad because this caused the person being be-headed to be in more pain and it then took longer for them to finish the execution. The fact that it didn’t always kill people/be-head people on the first go could have been because the blade wasn’t sharp enough or that the blade didn’t gather enough speed and so there wasn’t enough force when it dropped down to kill the person.

2. It didn’t always stop people from breaking the law.

3. It took a long time to set up

Political (how it changes peoples relationships with the government, and how it may hurt a democracy)

If the guillotine was introduced to a country or community it could lead to the people not liking their government if they imposed this on the people they would obviously not want to be, be-headed if they broke a law so they would probably up rise against the government and a civil war could break out. Then the government would obviously then be less powerful over the people.  This is how it would make the people’s relationship with the government became worse and less strong. This could hurt the democracy by creating a civil war against the government and the people would be unhappy with their government.

If the guillotine was introduced to a country or a community it could stop/scare criminals from doing illegal things because then if you did do something illegal then you could be be-headed. If this machine was introduced to a democracy it would probably also deter criminals from breaking the law as well.

I think that the negative things out way the positive things about guillotine because there are more negatives about the guillotine than positives. To introduce this to a democracy, a community or a country it would be bad, because the people wouldn’t want it.

I now can conclude that this machine is not worth making because the people would most likely be against it. And I think that if there was a choice or a slight possibility that the guillotine was going to introduced to a country it would be outvoted/outlawed at the first vote or decision.

This machine removed criminals from the democracy/community which was a good thing. But when you look at it in a different light its was a bad thing because you shouldn’t go around killing people because that is neither ethically or morally correct.

Ethical/moral things to do with the guillotine are:

The guillotine was a machine that was used in France in the 1700’s during the French revolution. It was used to behead criminals for wrong doings. It was also used to behead the people who tried to rise up against the king and queen at the time. I think this was ethically wrong because say if a criminal had murdered someone and then you think that’s wrong so you go and put them in a guillotine and cut their head off, that’s technically you being just as bad as they had been.

If you go around killing people for doing bad things then you’re being just as bad or worse then they have been. In my opinion they should be punished EG. Being put in jail for an amount of time instead of just being automatically beheaded.

But there were some good aspects of the guillotine too:

1.Criminals could be deterred from breaking the law.

2. Tax payers dint have to pay for the criminals to be in jail.

Which is not fair anyway. Why should we have to pay for their wrong doings?

I think that the negative things out way the positive things ethically or morally about the guillotine because there are more negatives about the guillotine than positives. If the guillotine was introduced anywhere today it wouldn’t be received well because today the people know right from wrong and to go around killing people is wrong. Everyone deserves a second chance not just to be killed.

The ideas i got for my machine from the guillotine:

From the guillotine I got the idea for the design of my machine and the layout of my machine of how my machine is going to work and how its mechanisms are going to work with the levers. I also found that the amount of downward force applied to my machine would affect its effectiveness, just the same as the downward force of the guillotine.

The tools I shall need when building my product:

1. A file and I will find this tool in the DT lab.

2. A tenant saw and I will find this tool in the DT lab.

3. A coping saw and I will find this tool in the DT lab.

4. Calipers and I will find this instrument in the DT/science lab.

5. Engineer square.

6. A hand held drill with a drill bit on and I will find this tool in the T lab.

7. A pair of scissors/snips and I will find this tool in the DT lab

8. A metal ruler for measurement and I will find this tool in the DT lab.

 

These are a selection of tools that are in theDT lab that i may need when building my machine :

To build my machine I will need the following:

A saw : a saw is a hand held tool with one jagged side which allows you to cut a piece of wood or another item. I will find this tool in the DT lab.

A coping saw:

Screen Shot 2013-09-25 at 2.42.40 PM

How you work it is you twist the peg in the corner and the blade will drop out then you can put the blade through a hole that you want to enlarge and re-attach the rest of the saw and cut where you wanted to cut. I will use this when I need to cut out the hole for my egg to sit in. I will find this machine in the DT lab.

My design brief:

My machine is going to be called the egg decapitator. It will cut the top off a soft-boiled egg, so you can dip your toast into the egg to eat the yolk.  Currently you have to use a knife and hold the hot egg with your fingers, which burns your fingers. It will have a piece of wood (that is held vertically upright by a wooden stand) with a hole in the wood and a plastic cradle to hold the egg in. This machine will be fairly cheap to produce, my resources will/won’t be sustainable because:

1. I will buy the wood for the machine from a company that will replant three trees every time they cut down one,

2. The metal will be sustainable because we will use recycled metal.

3. The plastic I am going to use will be a sustainable resource because it will be made out of recycled plastic.

My specification:

Target Market: People who like soft boiled eggs.

Function of Machine: To cut the top off a hot soft boiled egg without burning your fingers

Materials Required:

Wood

A lever/linkage

A metal blade

Plastic to make the cradle

Height: 15 centimeters

Width: 12 centimeters

Depth: 1 centimeter

Dimensions: Stand: 2 centimetres

Height: 3 centimeters

Width: 16 centimeters

Depth: 2 centimeters

Dimensions: Egg hole: 12 centimetres= circumference of an egg

Positioning of lever: The lever is going to be positioned on the same side as the blade (the rear) and then also connected with a nut and bolt to the blade.

Size of handle: The handle is going to be 2 centimeters long.

Size of blade: The blade is going to be 15 centimetres long.

Size of cradle:  The cradle is going to be 4 centimetres long to hold the egg.

Maximum weight of finished machine: The maximum weight of my machine is going to be no more than 1kg.

Colour: The machine that I am making is not going to be painted, the wood will be varnished with non toxic varnish.

The life span of my product:  will be three years long because it will be a sturdy well built and Structured machine.

The cost to make the machine:  7 euros.

Health and safety:When varnishing the machine you would have to be careful In which varnish you would buy because some varnish is toxic and when the egg is being cut some varnish could get on it and harm the consumer so when varnishing the machine make sure it is non toxic varnish.

WARNING: There is a blade on the machine parents please keep away from young children.

 TESTING AGAINST SPECIFICATION:

The test for my target market is: to send a group of people a survey of my machine to see if there is a market for it. This is the survey that I am going to use whenever collecting this data.

My target market survey:

1.Do you like soft boiled eggs?

2.How often do you eat soft boiled eggs?

3.Do you burn you fingers when you cut the top off a soft, boiled egg.

4.If not how do you prevent yourself from burning yourself when dealing with a hot soft boiled, egg ?

5.Would you use my machine?

6.Do you like the idea of my machine?

7.How much would you be prepared to pay for my machine.

8.How do you think I can improve my product?

9.Would you buy my machine.

10.If my machine was not to just specifically cut an egg, what other things do you think I could modify it to cut.

11.How much maintenance would you be prepared to put up with?

12.Who do you think would buy this product.

The test for the Functionality of my Machine is: to test the machine and see if it works like it’s supposed to.

The test for the dimensions of the main body: of the machine is going to be me measuring the length and width of a kitchen cupboard and then measuring my machine and seeing if it will fit into the cupboard.

The test for the stand on my machine is:  to measure the length, width and depth of my stand and taking the measurements of the body of the machine and adding them up and then seeing if it will still fit into a kitchen cupboard.

The test for the dimensions of the egg hole: I will put the egg into the hole and make sure it fits.

The test for the cradle is going to be, taking the measurement of the depth of the cupboard and seeing if the cradle is going to keep the cupboard propped open and from closing.

The test for the weight of my finished machine is: that I’m going to weigh the machine when I am finished building it and make sure it is no more than one kg.

The test for the varnish on my machine is going to be that: I am going to leave my machine outside for two months in all weather and see if the varnish holds.

The test against my products life span is: going to be that I am going to repeatedly use the machine 500 times and see if the machine still works to its full potential.

The test for the cost for me to make my machine is: for me to check with all the companies that I will be buying supplies from, and asking them how much it will cost to buy the supplies that I will need. I will then compare the total cost to the selling price recommended in my focus group

The test for health and safety is: going to be to look on the tin of the varnish and to make sure that it is non-toxic so I don’t harm the consumers.
