DT- Development

Comparing my two designs:

My first design does meet the specification points because all the specification points make sense and are relevant to this machine. This machine corresponds to the specification points in such a way that I will be able to fulfil them and it will work. Both of my machines will eventually meet the same need of the person who wants to cut off the top off their egg without burning their fingers.

 

My second design doesn’t meet all the specification points but it meets most of them the only real ones that it doesn’t meet are: the size and the colour. This would be ok because the colour doesn’t really matter and the size doesn’t make a huge difference to the machine either.

 

Specification points: The specifications either of my machines will / won’t meet:

Target Market: People who like soft boiled eggs. Design 1 = (1) Design 2 = (1)

Function of Machine: To cut the top off a hot soft boiled egg without burning your fingers. Design 1 = (1) design 2 = (1)

 

Materials Required: 

Wood. Design 1= (1) design 2 = (1)

A lever/linkage. Design 1 = (1) design 2 = (1)

A metal blade. Design 1 =(1) design 2 = (1)

Plastic to make the cradle. Design 1 = (1) design 2 = (0)

 

Dimensions: Main body:

Height: 15 centimetres. Design. 1 = (1) Design 2 =(0)

Width: 12 centimetres. Design. 1 = (1) Design 2 =(0)

Depth: 1 centimetre. Design. 1 = (1) design 2 =(0)

Dimensions: Stand:

Height: 3 centimetres. Design 1 = (1) design 2 =(0)

Width: 16 centimetres design 1 = (1) design 2 =(0)

Depth: 2 centimetres design 1= (1) design 2 = (0)

Dimensions: Egg hole: 12 centimeters= circumference of an egg.  Design 1 = (1) Design 2 = (0)

 

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. Design 1 = (1) design 2 = (1)

 

Size of handle: The handle is going to be 2 centimeters long. design 1 =(1)

Design 2 = (1)

Size of blade: The blade is going to be 15 centimetres long. design 1 = (1) Design 2 =(1)

 

Size of cradle:  The cradle is going to be 4 centimeters long to hold the egg. Design 1 = (1) design 2 = (0)

 

Maximum weight of finished machine: The maximum weight of my machine is going to be no more than 1kg. design 1 =(1) design 2 = (1)

 

Colour: The machine that I am making is not going to be painted, the wood will be varnished with non toxic varnish. Design 1=(1) design 2 = (0)

 

The life span of my product:  will be three years long because it will be a sturdy well built and Structured machine. Design 1 = (1) design 2 = (1)

 

The cost to make the machine:  7 euros. Design 1 = (1) design 2 = (1)

 

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. Deisgn 1=(1) design 2 = (1)

 

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

Design 1 = 22/22

Design 2 = 12/22

The questions I will ask my client:

1a. From looking at the drawing of my machines

 

b. How can I improve my machines?

You can improve your machine by reducing the amount of little things that are a bit impractical and can fall off and get lost easily.

 

c. Which machine do you think is most practical?

The first machine because it has a proper holder for the egg which the egg cant fall out of because the hole for it to sit in is a limited size and it has a cradle for it.

 

d. How much would you be prepared to pay for either of my machines?

I would be prepared to pay a maximum of 15 euros.

 

e. Which machine do you think would be easiest to store?

The machine I think would be easiest store would be the first machine because with the second machine there would be more little things that could fall off and get lost in the cupboard.

 

f. Which machine do you think would be more eye catching/appealing to the eye?

I think the second machine would be more eye catching/appealing to the eye because of all the little parts could be painted different colours.

 

g. Which machine do you think is safer for younger children to be around?

I don’t think either of the machines would be safe for children to be around because there is a big sharp blade on both machines and that could be dangerous.

 

h. What name do you think I should give to my machines? The eggatine/ The egg decapitator?

I think the egg decapitator is a better name.

 

2. Which one would you buy?

I would buy the first machine that you made.

 

2a.Which machine would you like me to make for you?

I would like you to make the first machine please.

 

This is the interview with my client :

Evaluating my specification points:

Target Market: People who like soft boiled eggs.This machine is specifically for people who like boiled eggs because if you don’t like boiled eggs wont use this machine because they wont make boiled egg and there for wont need to cut off the top of them.

 

Function of Machine: To cut the top off a hot soft boiled egg without burning your fingers.  This specification point will apply to my machine because that’s what my machine is made to do.

 

Materials Required:

 

Wood.

 

A lever/linkage

 

A metal blade

 

Plastic to make the cradle

 

All of these materials will be required to make my machine. So this specification point will apply to my machine.

 

Dimensions: Main body:

 

Height: 15 centimetres. The height of my machine will be 15cm, which is equal to 30mm

 

Width: 12 centimetre. The width of my machine will be 12cm, which is equal to 24mm

 

Depth: 1 centimetre. The depth of my machine will be 1cm, which is equal to 2mm.

 

Dimensions: Stand:

 

Height: 3 centimeters. The stand will be 3cm in height, which is equal to 6mm

 

Width: 16 centimeters. The stand will be 16cm in width, which is equal to 32mm

 

Depth: 2 centimeters. The depth of the stand will be 2cm, which is equal to 4mm

 

Dimensions: Egg hole: 12 centimeters= 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. The blade will be positioned in this way because it is needed on this side to allow the blade to drop with it and for it to then successfully cut off the top of the egg.

 

 

Size of handle: The handle is going to be 2 centimeters long. This specification point wont be met because there will now not be a handle you will use your hand to push down the lever with the blade on the end of it.

 

 

Size of blade: The blade is going to be 15 centimeters long. The blade will not be 15 centimeters long anymore the blade will now be 14mm long because if it was 15 cm long it would be the same length as the whole main part of the machine.

 

Size of cradle:  The cradle is going to be 4 centimeters long to hold the egg. The cradle is going to be 4 cm long, which is equal to 8 mm long. so this point will apply to my machine.

Maximum weight of finished machine: The maximum weight of my machine is going to be no more than 1kg. My machine will not be more than 1 kg because if it is it will be very heavy and less practical and harder to move/transport. So this point will apply to my machine.

 

Colour: The machine that I am making is not going to be painted. The wood I will be varnished with non toxic varnish. My machine will be varnished because this will then make sure that the machine will not give you splinters while you use because the wood will have been filed and finished. So this point will apply to my product.

 

The life span of my product:  will be three years long because it will be a sturdy well built and Structured machine. This is true to my product because it will be a made of good, sturdy materials.

 

The cost to make the machine:  7 euros. The machine should be no more expensive than this for me to make it or it is going to be harder for me to sell it to supermarkets ECT. because then they wont buy it because it will then be harder for them to sell it and also make a profit. So this point will apply.

 

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. If I use toxic varnish when building this machine I will harm my consumers and they will sue me so this point will apply.

WARNING: There is a blade on the machine parents please keep away from young children. This specification point will apply to my machine because for young children it will be dangerous for them to be operating this machine because of the big blade on it.

 

 My plan: The full sized product:

1. Making sure that all of my materials can be found in the DT lab because if they can’t I will have to go out and buy them
