4.1a Puzzle part combinations

11/14/2013

Intro: We will combine are puzzle cube parts.

Design brief:  During the process of creating blocks I decided to make the block easy to combine and make the mlocks more appealing to the eye.

Design:

Justification: Mr.H checked my blocks

Class comments: People like how my block are and they think it is easy to see as a cube.

                        

Creating blocks:

Conclusion:

The reason why it is important  for people to find different ways to solve something is so that they can figure out the fastest and easiest way to solve the cube. Inventors want all their products to be really easy to use so that it makes the person who bought the item happy and might recommend it to their friends. Making more sales and creating more production and more money.

The constraints that I used where mate and flush. Mate is when you want to connect two blocks together. This was really helpful for connection  your blocks together. The purpose of using flush was to put blocks right next to each other. This was really important to make sure the blocks were in the right position. All these blocks keep the blocks in that position so you can’t move them apart.

When someone says they followed the design process this means that took every step need to create something. They started of with a sketch or Idea like I did. They continue with Creating dimensions and putting these blocks on inventor. They continue with a 3d sketch of the object. They then create the blocks with wooden blocks and assemble them. Finally they create an animation of the cube being created.

The company might use the blocks as decorations for the store or sell them. They can use them to repair broken furniture.


Activity 5.2a Geometric Constraints

1/8/14

Intro:We will Geometric Constraints shapes.

Conclusion

1: Geometric constraints are when you change shapes by moving, connecting, and changing how shapes appear.

3: A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point..


5.2b introduction to CAD modeling skills

1/9/14

Intro: We will be creating CAD models.

Model:

Conclusion:

1: Cad sketches are more prices and you can have straighter lines. The CAD sketches also have more features and can fillet lines easier.

2 Regular sketches are more hands on and free to your liking.


5.5 CAD Model features part 1

2/10/2014

Intro: We will be making model features.


Conclusion:

1: One of the things you can do to create a coat hanger would be to use a sweep. As you can see from the paper clip, we used the sweep to make curls and non straight parts. This would come in handy for making a coat hanger.

5.5 part 2

2/13/2014

Intro: We will be doing more CAD drawings.

Conclusion:

1. To create a baseball bat CAD sketch One tool you can use is the revolve setting. This setting will help by making one side of the bat and then use revolve. Revolve will make the other side and extrude it will rounding it.


6.1 Visual Design Principles and Elements Identification

2/21/2014

Intro: We will choose a part and reverse engineer the product.

1: The part that I have is a Micrometer Stand. The price is 29.95. It is half organic shape as well as geometric. This part is used to hold micrometers still so that you don't need to hold the micro meter.

Emphasis - It is dark green and black easy to see nobs.

Contrast –  The knobs stick out from everything else.

Formal balance –The part that hold the micrometer and the knobs stick out from the rest of the part.

Regular Rhythm – The lines on the holder have rhythm.

Proportion –  The base is the biggest part and the knobs are much bigger than normal sized knobs.

Unity –  Use of cool curves and smooth surface.

Economy – Rounded lines and as well as straight lines.

Conclusion:

A product that i feel is appealing is a couch. These couches are a sacred tool in which people lay or sit on. The softness and comfort of couches makes them appealing.


6.2 Visual analysis

2/24/2014

 Intro: We will be doing a Visual analysis.

The part that we have is a Micrometer holder.


6.3 Functional Analyzation

2/25/2014

Product name:Micrometer holder company name:Unknown Purpose:

 To hold a micrometer will you measure objects with it. You spin the knob and it tightens the teeth you spin the second knob and it changes the degree.

 2:1. Why do engineers perform reverse engineering on products?

 5 Clamps Knobs screws.

2. What does a black box represent in the system input/output model?

 6 There are no invisible components.


6.4 Structural analysis

3/12/2014

 Intro: We will disassemble and 3 d sketch the product.

https://docs.google.com/a/student.leyden212.org/presentation/d/18jSTB4wIZgVjg_6uOGOT44-_2lVoygvUUvt-oaIYX6A/edit#slide=id.g1d58af2a5_10

Conclusion:

1:  The first thing you do is tell what your part is and then take it apart find out what things work with what and draw each part.

2: once you disassemble the part you start to figure out what things work with what.

3: Consumers will use this product to hold there Micrometer still when trying to measure things.

4: You twist the Big knob to hold the micrometer still.

5: Yes it was.

6: I would redesign the base because there are so many unneeded designs on it.
