Investigation
Monday, March 2, 2011
IntroductionSituation:
People often find mechanical devices amusing. Automata are mechanical devices that perform movements automatically. They go through a routine designed to be amusing. There is a growing market for ‘Automata’ as toys.
Client? MR BLOGGS
Task
I am required to design and manufacture a prototype ‘automata’ with two attractive moving parts. The automata will be for a client of your own choice.
Unit Question: How can motion be used in a mechanical toy?
Monday, March 2, 2011
AOI
Human Ingenuity
I chose Human Ingenuity because I will be making a mechanical toy. When we’re building this toy, we will need
creativity on how we construct things and make things work. I think human
ingenuity is all about creativity and how human work/process.

TYPES OF MOTION
Monday, March 2, 2011
Linear MotionLinear motion is a motion that goes in a straight line.
Linear motion is the most basic motion.
Monday, March 2, 2011
Rotary MotionRotary Motion is motion that turns round in a circle. Rotary
motion spins around. The examples of rotary motion could be a turning wheel and a ferris wheel.

Creative Caterpillars, neat,
good quality
Nice colored fish and cat, neat, good
quality
Cost $6.40 $11.29 $12.30
CustomerKids, because the
would just push and pull the toy and the
ducks move
Kids, It would most likely entertain kids on how the
worm moves.
Kids, because they will be most entertained by how the fish went to the cats
mouse after the toy is wind up.
EnvironmentThis would probably
made out of plastic so it would destroy the
environment because it is hard to be decomposed.
The material was made out of plywood, that is easy to grow. It will be cheap
and since it grows fast it will be more friendly to nature. But then the paint
would be acid so the won’t be good for the environment.
It was made out of plywood, so it would be
safer to the nature. The fish tank will be bad because it
is made out of plastic.

SafetyIt is very safe, because the ducks will roll smoothly,
perfect for children
Source 2 would be safe if the box doesn’t have
any sharp edges
Source 3 would also be safe if the box doesn’t have any sharp edges
Size The size will have to be big for children to pull.
The size is good enough

Gantt Chart
Monday, March 2, 2011
Evaluation of The PlanI think the planning I made was detailed
enough , so that people could just follow my plan when they are making another
mechanical toy. I think my plan is helpful, especially for the gantt chart because it tells the specific time I will be using for each of the manufacturing I do. The step by step would also help to know what we will be
doing in a simpler way.

CreateDocumented Evidence
Monday, March 2, 2011
On the Design stage, I made a design of a horse riding mechanical toy. On this design stage, I will be making
a documented evidence of how I am going to manufacture this mechanical toy. I will be following the step-by-step plan and the gantt chart so that I
don’t waste much time on doing something.
The design I made:Horse riding

Week 1
I chose 2 PAIRS of plywood. 1 pair of plywood will need to
be the same size.
1 pair
1 pair

We TAPE the wood together. We will be using these pile of wood to make the MACHINERY BOX of
the mechanical toy.
Monday, March 2, 2011
I draw the BODY of the horse...
Then the HEAD of the horse...
IN ANOTHER PIECE OF WOOD...
After that, the LEGS of the horse...
Monday, March 2, 2011
Week 2continuing to draw IN ANOTHER PIECE OF WOOD...
I draw the BODY & HEAD of the horse
rider...
Last but not least, the LEGS & HANDS of
the horse rider...
Monday, March 2, 2011
I cut each of the pieces with the fret saw. I NEED to where the glasses while cutting it with the fret
saw for SAFETY.
I am a fret saw
I am a blower
The BLOWER will help me GET RID of the dust that is
covering the LINE that I should cut.

Week 3Mechanism time !
I chose three blocks. Two with the same size, and one with a
longer side.
Then I smooth those three pieces of wood...
I used the sanderMonday, March 2, 2011
I drill the hole on to the pieces of wood.
I am a Drill
Addition (+):There are three kinds of drill in the DT LAB (Small,
Medium, Large) . You would want to drill the two same sized wood with the MEDIUM SIZED drill.
And the longer sized block with the BIG SIZED drill.
Monday, March 2, 2011
It will end up like this...
two holes of the medium sizedOne hole of the large sized
Monday, March 2, 2011
Pick three sticks. One short, and two longer with the same size...
Hit the stick with a hammer onto the blocks
I am a hammer
I am a HAMMER.
My job is to place the sticks in the
wood.
Monday, March 2, 2011
But the other stick was too small to put in the block. So, Mr. Julian told me I could use the GLUE. This will make it stick in
the block.
I am a GLUE and I will glue this
stick together to the block.
I am a GLUE and I will glue this
stick together to the block.
Mr. Julian said that it will be strong in 24 hours. So I let it dry...
Monday, March 2, 2011
Week 4 I drilled a large sized drill onto the wood that is for the mechanical
box.I drilled it in the centre
For the horse, I started drilling a small sized hole
through the bottom
Monday, March 2, 2011
and another small sized hole through
the mechanism
It will end up like this...
Monday, March 2, 2011
Working on the horse !Firstly, I drilled a hole through under the head of the horse, and the upper end of the horse’
body.
Then, I sticked a thin strip of wood between the head and body of the horse. This will become the neck of the
horse.Monday, March 2, 2011
Firstly, I drilled a hole through under the person and on top of the horse’s body. With a Small sized drill.
Then I painted the person white
Also, I place another thin strip of wood
between the person and the horse. And the horse black
Monday, March 2, 2011
I also painted the wood for the mechanism box
I painted it brown because it’s the color of wood.
I leave all the painted wood dry, for next week!
Monday, March 2, 2011
Week 5I start putting things together
Nail up the feet of the guy together
and also sticking the hand of the guy with the
glue gun.
Monday, March 2, 2011
Same thing with the horse. I paint it black
Nail those feet into the horse
Monday, March 2, 2011
I didn’t forget the eyes too! I cut it, smooth it and paint it!

Week 6 MAKE IT SHINY!
Ingredients: Water+Glue
First, put the paint brush into the bowl of “Water+Glue”
Second, Wipe them off to the whole body to make it
shinier

EvaluationMonday, March 2, 2011
InvestigationThe Investigation was the longest part of this process since we need to do the AOI, the Case Study, Design Speci=ication, etc. I think the hardest part on this stage is to make the case study because I will have to criticize three designs. I think I already improved much from last year and doesn’t need further improvements.
DesignFor this stage, I think this stage was the hardest stage in the design cycle. I would need to brainstorm creative ideas and choose one among 6. But the hardest I found most, was the designing in which I had used google sketch up. I think I would need further improvements at google sketch up, so I wouldn’t be wasting much time on it.
PlanThe plan stage is the 3rd stage in the design cycle and is the easiest since I only need to do my Gantt chart and the evaluation towards my step-‐by-‐step plan. This stage is an important stage because all we need to do is follow the Gantt chart. The Gantt chart also tells us how much time should we waste for doing a job so that we won’t waste time focusing in one job. I think I wouldn’t need any improvement for this stage.
CreateThe create stage was the 2nd hardest stage but it wasn’t also that hard because it was the funnest stage of all. In this stage, we had made our =inal product of mechanical toy. Although, this stage was a really long process. So, we would need the documented evidence about our long process of manufacturing. Since it was a long process, I would also need to improve on saving time. I had also learned a lot of new machines that could be used to manufacture in the DT lab.
EvaluationI think this re=lection process is kind of long, and the most boring stage in the design cycle. While evaluating, we have to tell everything that we had done in the design cycle and I think this re=lection is really useful to re=lect ourself through the project.
