Prototype Test (Video)

Prototype (Upgraded)

• We had some problems with the previous prototype, and we upgraded them by solving the problems. 
• The first problem was the type of tube. The colour of the tube we have used for the previous prototype was white. We have purchased the one that is clear so the powders can be seen through the tube. 
• The next problem was that the number of tubes we had to produce. For three different amounts of powders for three consistencies, we had to make three different sizes of the tubes. However, we thought that it would be much better to make just one tube that can be used for the all three of the consistencies. Therefore, we have made the wooden tool much longer. 
• Also, we thought about putting the rubber around the tube so the height of the tool can be adjusted inside the tube. We found the useful material which is called "O" ring. By doing so, the amount of powders we can get from the tube becomes more accurate
• The photos below show the steps we have done when producing our device. The sketch was drawn with dimensions in full scale, and it was used when we made our product.

• We are thinking of putting a scale sticker on the clear tubes. The scale sticker will show the numbers in centimetres. The numbers such as 3, 5 and 11 (cm) will indicate that the amount of powders required for the specific consistency, Ketchup, Mayonnaise and Peanut Butter. The transparent scale allows easy measurement of the volume.
• The inside diameter of the clear PVC tube is 3.4 cm. 
• We use the numbers from the table (previous post), and then we have calculated the volume of the powders we need for each consistency. This volume will be used when defining the heights.

How to find creative ideas

"When we think of improving something we tend to think of adding something to it"

However, "improving also means removing".

Learning Outcome 5

Explain any implications of Te Tiriti i Waitangi

1. How do we demonstrate our understanding of the 'implications of the Treaty of Waitangi' in our technology project?
2. What were initial expectations in our process regarding the implications of the Treaty of our technology project?
3. What supports, challenges and dilemmas were encountered as we attempt to fulfil the technology problems towards the Treaty within our technology project?

Plastic Systems

We have been to Plastic Systems to purchase clear PVC tubes. We bought a 32mm (diameter) and 500 mm long tube and cut in three pieces. These tubes will be used for our prototype. 

The difference with the one we have produced before is that this tube is clear so we can see inside of the tube. Using this clear PVC tube would be much better than using glass tube as it is strong and not breakable.
