Week 3 Lesson

 SCAMPER 8 Ideas

  1. Cooling Jacket

  • By adding fans and cool water tubes inside the jacket, it acts like a heat exchanger to exchange heat from the body to the cooling water in the tubes, allowing the user to stay cool.

  1. Cooling Hat

  • That can be accomplished by adding misting fans on top of hats so that the mist will land on our body/face. Through evaporation, it will absorb heat from our bodies and allow users to stay cool.

  1. Cooling Pillow

  2. Cooling Blanket

  3. Portable Air Cooler

  4. Cooling Backpack

  • We can add a cooler in the backpack so that the cold water will run through tubes inside the backpack cooling the back or also by adding fans at the back. At the same time, it can be used as a normal backpack for school or work.

Decision Matrix Template

 A COWS decision matrix is used as a low biased method to choose the most suitable option for our topic. COWS stands for, C: Criteria, O: Options, W: Weightage and S: Score. The following criteria are used for the selection:

  • Functionality

  • Ease of Fabrication

  • Portability

  • Ease of Maintenance

  • Cost

A weightage is assigned to each of the criterias according to its importance. The total score is then calculated. The option obtaining the highest score will be selected as the most suitable idea for our topic. Rating scale from 1 to 3 is used, 1 being the poorest and 3 being the best.

With the cooling backpack obtaining the highest score of 250, it is the most feasible idea for our topic. Its value lies in its high ease of fabrication and portability.



Original Idea that SCAMPER was applied on: _________Cooling Backpack______________

New idea from the application of SCAMPER

S/No

Brief Description of Idea (Include

sketches, if appropriate)

SCAMPER Word used

E.g.

Curry puff skin but substitute the curry

potato fillings to custard

Substitute

1

The padded back panel is modified to include

a fan cooling system to keep user cool


Modify

2

The backpack straps are modified to insert

a cooling tube to keep user cool



Modify

3

The case of the backpack is substituted with a

waterproof material to make backpack waterproof



Substitute

4

The fan in the back panel can be used as a portable

fan when backpack is placed down



Put to other use

5

make backpack a thinner and smaller profile just for

the cooling equipment for people who do not want

to carry a big bag everywhere



Modify

6


Make heater instead of cooler for people living

in cold conditions


Adapt

7

The materials used to make the strips and the

back of the backpack can be modified to have

more holes in them to have a better air circulation

and better cooling effectiveness.

 

Modify

8

The use of cooling system in the backpack can

be used as a drink cooler inside the backpack.

Put to other use

Reflection 

In this week's lesson, we learnt about SCAMPER, which stands for Substitute, combine, adapt, modify, put to other use, eliminate and reverse. It is a method to come up with ideas from a broad topic. For example, the questions that we ask ourselves for adapt are ‘how can we readjust so that our product can be made for other use?’ In our case perhaps in places of cold weather instead of hot weather, the adaptation might be to replace the portable cooler with a water heater for the backpack so that it pumps warm water around the tubings, keeping the user warm. That way it depends on the consumer’s needs. 

 We also recapped the COWS decision matrix, which is a method used to eliminate/ find the most optimal material/product by deciding using a table with different grading criterias, for example, which can be tensile strength to grade for metal. For our main criterias, we decided on functionality, ease of fabrication, portability, ease of maintenance and cost as we came to the conclusion that the criterias are relevant to our products and will allow for a fair judgement without bias.

    Team, as mentioned in the lesson, do organise your weekly blog entries into different tabs so that they can be accessed easily and I will not miss out on any important content. Thanks.

 Hello peeps. This week we carried out an experiment we were assigned called the air-lift pump challenge. we were required to contract the set up with provided equipment.  Here is our equipment and experimental setup  Here are the results we obtained from the experiment Experiment 1 b = 10cm, Y=16.5cm a (cm) X (cm) Flowrate (ml/s) Average Flowrate (ml/s) Run 1 Run 2 Run 3 2 14.5 5.93 5.80 5.71 5.81 4 12.5 4.20 4.13 4.23 4.19 6 10.5 2.82 2.63 2.60 2.68 8 8.5 1.39 1.11 1.93 1.47 10 6.5 0.39 0.37 0.39 0.49 Experiment 2 a = 2cm, X=14.5 b (cm) Y (cm) Flowrate (ml/s) Average Flowrate (ml/s) Run 1 Run 2 Run 3 10* 16.5 5.93 5.80 5.71 5.81 12 14.5 2.89 3.78 3.20 3.29 14 12.5 1.35 1.35 1.20 1.3 16 10.5 0.19 0.19 0.18 0.19 18 8.5 0 0 0 0 20 6.5 0 0 0 0 we used an estimated flowrate of 0 as t water was barely being pumped out. it took too long to collect 100ml of water and it was not feasible for the experimenter to hold the tube for so long. 1.       ...

Week 4 Activity

  Roy, Nigel ,Bjorn, Vernon Group 3 DCHE2A02 Topic: Material Selection for Inner Layer of Thermoflask For week 4, we went to revisit our last year module which was the materials for design and we were tasked to find the right material for the inner layer of a thermoflask. In materials for design, we needed to find the right requirements for the material and from there find different suitable materials. We then use the COWS matrix (Criteria, Options, Weightage and Score) to determine the best material. Here is our findings. Material Requirements In order for the liquid inside the thermoflask to remain hot/cold, the inner layer of the thermoflask must reduce the amount of heat transfer from the liquid to the surrounding. The inner layer thus should have a low thermal conductivity and a high melting point.   Since the inner layer will be in contact with water, it must resist corrosion by any liquid put into it, water and acids from soda drinks. It will be used for drinking, so i...

Week 1 Group Retreat Activity

 Firstly, we went to buy drinks as we were feeling very thirsty and while drinking we were chatting about the stuff we did during the holidays.  After finishing our drinks, we had to use the toilet. We also decided to prank Vernon by taking a wefie with him using the toilet. We were feeling stressed due to the long and hectic day and decided that we needed to distress by playing some mobile games together. We were feeling restless, so we decided to do some pushups together. Despite it being tiring, all of us had plenty of fun together. All in all, this was a fun bonding experience for our group and we felt that this opportunity allowed us to get to know one another better.
