Technological Design: Final Evaluation
Transcript of Technological Design: Final Evaluation
Technological Design: Final Evaluation
From the beginning...
Starting from the beginning weeks of school, the very first tool we learned was safety rules within a technical facility. It was crucial for us to learn these rules so that we could operate safely in a technical facility. Some of these rules included:
- do not wear loose clothing
- do not engage in roughhousing or horseplay
- use machine guards at all times to prevent injury
-do not wear sandals or open toed shoes
These rules became second nature to us as we began the course and our projects.
After learning the safety rules we then moved on to learning how to dimension. We learned...
- there are two main types of dimensions: over and detail.
- over= give the full length, height and width of the object.
- detail= give the size and location of various parts of the object.
Once we knew this there were a few rules we had to follow while dimensioning plans. They were:
- all dimensions must read from the bottom of the drawing.
- extension lines may cross, but dimension lines must not cross other lines.
- extension lines start 2mm from the object and extend 3mm past the last dimension line.
- where is less than 10mm arrows are placed outside the extension line and the dimension is placed between them.
Applications of Architectural drawings...
For our first project we took the information we had learned so far and applied it. We used the safety rules, dimensioning and scale, and our own architectural drawings to build our own deck. This was our first project and each of our groups had to design and build our very own deck out of wood. We first learned about permits and codes to building decks. We learned that a permit was a document that secured that the safety of your the structure you were building, it also gives you permission to build the structure. We also learned different codes that we must follow while building our deck. Some of them included:
- every walking surface must be protected by a guard where there is a height difference of 600mm.
-a 3 ply 2x8 SPF beam must be supported by a post or pad every 8'-o"
-lumber in contact with 12" of grade level must be pressure treated.
After we learned these rules we began creating working drawings of our own designs, and once they were completed we began to build our models. our decks turned out fantastic and we had our first project under our belt.
The First Project...
During this time we also learned about scale:
scale is a ratio of an actual objects dimensions compared to the dimensions on the drawing.
ex) 1cm: 100cm- where 1cm on paper is 100cm in real life.
After we learned how to dimension and scale our work we then spent some time learning how drawings are used in an everyday setting. We learned that there are 6 types of architectural drawings:
-plans: "birds-eye" view of drawing.
-elevations: two dimensional view of drawing
-sections:view of one slice of a planned structure
-detailed drawing:reveals precise info on methods and materials of the structure
-renderings:1,2,3 point perspective of the drawing. shows what the final result will look like
- models: 3D replicas of the structure
We also learned that drawings are used 3 ways in the planning and construction of a building. There are general purpose drawings, working drawings and constructional drawings.
general purpose drawings: give apporx. sizes of rooms and dimensions on a single line floor plan
working drawings: contain all information needed to complete and construct the building
construction documents: contain hundreds of facts and figures plus legal and financial info . needed for the building process
The next step after finishing our decks was taking our hand drawn drawings of ourprojects and transferring them over to Auto CAD. Auto CAD is a software that allows you to draft your architectural drawings 2 and 3 dimensionally. We learned specific ways to best develop our drawings. We learned how to begin our drawings in the command box. we learned that:
to create a line enter "L" in the command box
to give the distance of the line you wish to create enter the length into the command box and press enter
to specify a angle enter the length@<the angle (ex @80<270)
to dimension go to the dimension and click on the two points ou would like to dimension.
we also learned terms such as Grid, Snap, and Ortho
This was tricky at first but we eventually all understood and was able to use the programme.
Project Number Two...
The next project we received was designing our own dream home. We were allowed to design anything we wanted but the house had to meet a few specifications. It had to be one floor only, and it must involve wind powered energy. Like our other project we first had to create a set of drawings. Once our drawings were complete we began making a model of our house according to our drawings. We used foam board to create the walls, appliances, and roof of our homes. After this was complete we learned about the different types of natural energy that could be used in our homes.
Geothermal: energy created from the heat in the interior of the earth
Solar: energy captured by the suns rays through solar panels.
wind:conversion of wind into a useful source of energy through wind turbines.
Once we learned these different forms of energy we were able to build our turbines for our homes. The challenge was being able to place the turbines on the roof of our homes.
The Third Project...
After our second projects were complete it was time to move on to our third, the brain bucket. The goal for this project was to create a helmet that a water balloon could fit into and be dropped from two meters in the air and not break. This project forced us to think critically and create the safest helmet possible. Many of us used different kinds of padding to protect the balloon from breaking against the force of hitting the ground. When it came to testing the projects each group had a different outcome but no matter if the project worked or didn't we all learned and tried our best!
After our third project was finished it was time to learn about auto design. We learned about the different parts to an engine and specific parts to a car. An engine contains an exhaust valve, an intake valve, fan, carburetor, spark plug,crank shaft,connecting rod and piston,engine block and cylinder, and a cam shaft.We also learned that depending on how many cylinders the car has determines the max speed it can reach.For our next project we had to learn to make a model car. We took apart each piece and built our own engine and outer shell of the car.
Throughout the semester we have participated in a number of hands on activities that have taught us how to create and design our own projects using a variety of different media and technology.
Technological Design in Our Society...
Throughout the course of the semester we have learned many environmental, societal and cultural aspects associated with technological design. During the semester we have learned that in order to keep our environment alive and well new designs for technology must occur. We learned that new designs are always changing to benefit the environment. New forms of solar panels, wind energy, and geothermal energy are improving and becoming more popular amongst society. We have also learned that a number of occupations are available that focus on technological design and are in great demand for our changing society. Some include software engineer, graphic design, automotive design, carpentry and many more. An example of one of these jobs is...
Interior design is an occupation that is responsible for designing the decoration of a room or building. An interior designer's job consists of designing an interior space that functional and beautiful to be in.
In Ontario Ryerson University in Toronto has an Interior Design programme that takes 4 years to complete. Once one finishes the programme you will receive a Bachelor of Interior Design. During this programme students will participate in a number of hands on tasks that teaches the students the principles needed to design a beautiful space.
In Michigan schools such as Eastern Michigan University, Lawrence Tech, and Western Michigan University also have Interior Design programmes that will allow students to earn a Bachelor of Interior Design.
