context

We will discuss in this assignment (L3) The problem solving strategies which are :

• Problem Definition.• Generate Solutions.• Decide .• Implement. • Evaluation.

Context

If any one want to solve any problem the first step from the heuristic it is Define the Problem

As we know the definition of any problem depends on:

• Gathering information

• Defining the real problem

• Evaluating of the problem

These steps happened by using some techniques (present state/desired state, dunker diagram and statement/re-statement). In the end we will have achieved an important side in doing the project.

Information Gathering

• The first steps that must to do when you want to define the problem.

• We asked some students if he has any ideas about manufacturing ?

• These is the ratio between who know some thing and who know nothing

Information Gathering

• Then we ask who has not any information about manufacturing what is the reasons?

There are some answers I explain it in this graph.

the reasons from student look

Education27%

no encourage

10% Don’t want to learn7%

University courses

14%

family 14%

Like office work7%

Environment 14%

No trip to factories7%

Information Gathering

We asked a Doctor “why the students have no or less ideas about manufacturing”

1. The students don’t want to learn and search about manufacturing.

2. Environment.

3. No television programs talk about manufacture.

4. No encourage.

5. Education .

6. The family.

Present State/Desired State

Present State Desired State

Some students don’t know enough about manufacturing.

Each student should have enough knowledge about manufacturing.

These two statements now matched and the distinction between them is sharp.

Duncker Diagram

Statement Restatement

• Statement: Students do not know enough about manufacturing.

• Restatement 1: Students do not like to learn about manufacturing .

• Restatement 2: Students don’t read about manufacturing.

• Restatement 3: Students have a little information about manufacturing.

• Restatement 4: The information about manufacturing is not easy to get it.

• Restatement 5: students not guide to the importance of learn the manufacturing.

Five problem definition

• The society and environment are not manufacturing.

• Students do not know the important of manufacturing.

• The university does not give the training more care and time.

• Education before university does not have basic for manufacturing.

• Students do not try to manufacture any thing.

Evaluating the Problem Definition

1-Have all pieces of the problem been identified?

Yes we have identified of the problem.

2-Have all the constraints been identified?

Yes we have identified all the constraints.

3-What is missing from the problem definition?

Nothing of missing from the problem definition.

4-What is extraneous to the problem definition?

Nothing of extraneous to the problem definition.

5-Have you challenged the assumptions and information you were give to formulate the problem?Yes, we have challenged the assumptions and information you were give to formulate the problem.6-Have you distinguished fact from opinion?

Yes, we have distinguished fact from opinion

Discussion

In this assignment we learned the real problem of why student do not know enough about manufacturing .We know that the student do not guide to learn the manufacturing or do not have motivation to learn .We think this define the problem using problem definition techniques will help us to maintain time and resources, then we can generate solutions to the problem which is the second heuristic technique.

context

• After we defined the problem in (L3-A) we will go to next step. In this part (L3-B) (Idea generation). Firstly every member write 20 artifacts then we used Boggle Method to delete the same idea, after that we multi voting to choose between 6-10 artifacts. Then we repeat same steps for the must and wants. Also we used other techniques which are Osborn's checklist and Random Stimulation. We use Osborn's checklist for the musts and Random Stimulation for the wants. Finally we enjoy with this project and now we have some ideas about the next step from our project.

• What are the Possible Artifacts?• In L3-A we define the problem and now in L3-B

we start to learn about manufacturing .• To generate idea about Possible Artifacts we did

some steps:• First step every member used brainstorming

technique to generate 20 artifacts.• Second step we delete the same ideas by

Boggle method.• Third step we choose 10 ideas by using Multi-

voting.

• Third step: Multi-voting.• After we eliminate the duplicate artifacts

by Boggle Method we voting to choose 10 artifacts from 57.

• Also, we calculate the artifact and divide by 3 to determine the member of voting to each member.

• 57/3=19• The table

• toy car• radio• electric motor• bicycle• mobile• telephone• alarm• Play Station• toys• computer

• Mandatory to achieve a successful solution and they have to be measurable.

• 1- More than 10 parts

• 2- Not damage the environment

• 3- Medial cost80-1000 SR

• 4- made from metal

• 5- Electrical artifact

. Not weapon Adapt? Paint gun

Easy to switch on Modify? Switching on wireless with remote control.

Not damage the environment

Magnify?

Not damage the ozone layer.

It has colors Minify? It has only two colors.

. Made from metal

Substitute? Made from plastic

Use battery Rearrange?

Use gas

Easy to fixEasy to carry

Combine? Doesn't have thick material.

• Safety

• Important using

• Easy to draw it

• Easy to development

• Mechanically

• Car accident Repair It has spare parts

• Mountain Marble Beauty shape

• Snake skin wallet High quality

Discussion

• After hard meeting, we reviewed the (L3-B) project from many views. The context, brainstorming, Boggle method multi-volt, Osborn's Checklist and Random stimulation have done it in the correct way. So we learn a lot of thing from this assignment which like how can we use all technique in the top. We believe that after we generate a list of artefacts we can use KTDA in the next step in order to select artefact then solve the problem.

• That's mean we ready now to go to the third block of the HEURISTIC "L-3C" which is taking about "Decide the Course of Action".

Context

• This is our presentation of the third part from our project L3 we will take about some points:

• KTDA table

• Adverse Consequence table

• Cost estimation

KTDA Table

• After we used KTDA Table we get four alternative solution from nine

• Electric DC Motor.– Electrical Motor ……………………………..100 SR– Working tools ………………………………..10 SR– Electrical Experience …………..…………….Free– Mechanical Experience ………………100 SR for the project.– Another Mechanical Experience ……………...Free– Improvement parts …………………………….100– Members work …………10SR * 5 members * 5 hours =250 SR– Printing papers ……………………………………50 SR– Exploitation ………………….………………… 50 SR

• The total 660 SR

• Toy car.– Toy car ………………………………………… 70 SR– Working tools ………………………………….. 10 SR– The experience …………………….50 SR * 1 hours = 50SR– Improvement parts ……………………………….5 SR– Members Work …………10 SR * 5members *0.5 hour = 25

SR– Printing papers …………………………………….. 50 SR– Exploitation ………………………………… 50 SR

• The total 260 SR

Finally

• the selected artifact is the Electric DC Motor based on the KTDA and on the Adverse Consequence analysis and this project will cost us approximately 660 SR.

Discussion

• At the end of this assignment which was on the third tasks – Artifacts Selection- we selected our artifact for our project is “Electric DC Motor” because it got the highest score on KTDA table but it was not get the least score in the Adverse Consequence table this is not real problem because if we have same this situation we can choose what we want if we remember the different between the score was too small. Now we feel that we can apply the KTDA in any decision making case on our life .

Context

This is our presentation of the fourth part from our project L3 we will talk about Implementation we have some main points

• KTSA table

• Gantt Chart

• Artifact parts

• Part name and work

• Disassembly process

KTSA

Gantt Chart

Artifact parts

Part name and work

Disassembly process

• Remove the electric cover (part1).• Remove the circle cover ,then remove the

cylinder cover, take care it has magnetic part here you need more force to remove it.

• Now you should Take care to get the generator out you must do some steps :firstly, take the carbon parts out. Then the springs. Now you can remove the heart easy.

Discussion

After we did this work we now the disassembly plane , we now the artifact parts, we study all parts, also we know how can we assembly the parts. That’s what we will do in the next work (L3-E). we can use the KTSA table and Gantt chart .

Context

This is our presentation of the fifth part from our project L3 we will talk about Evaluation the solution we will explain some main points

• BOM• Initial assembly plan• KTPPA• Final assembly plan• Assembly test• Evaluation • Finally cost of the project

BOM

Initial assembly plan

• Put the three springs in its places. in the base).• Push them by the carbon parts. • Insert the heart (Generator) on the hole which in the

base. The generator will be between the carbon parts. The big side will be up the carbon parts and the other will be in other side.

• Put the generator cover up the generator and fix it by the two nails and nuts.

• Put the circular cover up the plastic gear and fix it.• Finally, put the plastic cover on its place up the

electrical area.

KTPPA

Final assembly plan• Put the three springs in its places in the base).• Push them by the carbon parts. Keep the carbons and

springs inside them area any way.• Insert the heart (Generator) on the base hole. The

generator will be between the carbon parts. The big side will be up the carbon parts and the other will be in other side.

• Now let the carbon parts free it will touch the generator.• Put the generator cover up the generator and fix it by the

two nails and nuts- take care the cover has magnetic part you need more force to put it in the correct place, don’t try to ball it quickly you will bull the generator and break the carbon parts-.

• Put the circular cover up the plastic gear and fix it.• Finally, put the plastic cover on its place up the electrical

area.

Assembly test

• We take our artifact with the final plan and give it to Mohammed’s friend he takes 20 minutes he said “ the plan clear but the artifact need more careful when you want to assemble it”

Evaluation

• Environmental Impact

• The corrosion of metal specially the iron. This impact happen in special situation where located Oxygen and Humidity

Social Impact

• The old man can use it easily.• The ill and sick use it easily.• Save time when you repair the tire quickly.• If women will be a driver she can use it easily

Cultural Impacts

• There is no cultural impact for our project.

Economic Impact

• If the car companies take our project and made it in the new cars there will be increase the car cost may be it not more put there is

Finally cost of the project

Discussion

• In this assignment we learned how to assemble plan for our artifact (Dynamo). Also we deal with unexpected problem by using K.T.PPA table, so we change our plan of assembling to deal with the assembly after considering the potential problem. Then we test our plan. After that we study the negative and positive impact of environmental, society, economic and cultural of our bicycle.

• Go to movie

Discussion

After we finished this work We learned a lot of thing:• Work as a team.• Write the reports.• New English words.• Make presentation• Solve problem by the five techniques• Define the problem by many techniques• Generating the solutions• Decide the solution• Implement it• Evaluate the solution• And so on…….
