Design brief

Design Brief

It is basically a “summary” of the project

How to create a “Design Brief”

  • State the Problem, underline key terms

  • List the Constraints (limits)

  • Brainstorm ideas.

  • Draw up sketches, lists, etc.

  • Select a Solution- draw final drawing and prepare 3d models.


Design process1

#4 of the design process states “Draw up sketches”

You must learn how to sketch so that you can complete the design process.

Design Process

State the Problem, underline key terms

List the Constraints (limits)

Brainstorm ideas.

Draw up sketches, lists, etc.

Select a Solution- draw final drawing and prepare 3d models.

Make a prototype.

Sketching techniques

Sketching

Sketching

Sketching is a freehand drawing. This means that it is drawn without the aid of any equipment. Sketches do NOT have to be excellent quality. They are rough.

Why do we sketch?

  • It is a fast and easy way to organize your thoughts and get an overall picture of the item you are sketching.

  • Helps minimize errors on the final drawing.


General sketching techniques

General Sketching techniques

  • Always make strokes from left to right and top to bottom.

  • Hold the pencil at a 30 degree tilt.

  • Rotate paper slightly

  • Use short, light lines


Sketching straight lines

Sketching Straight Lines

  • Mark the beginning and end points of your line with dots

  • Without touching the paper, make a few motion trails with your pencil to practice where the line is going to go.

  • Sketch very light, short lines (2 to 3 inches) between the dots

  • Keep your eye on where you are ending.

    Try it. Draw 2 dots 4 inches apart

3 methods

  • Letter O method


Measurement lines and proportions

Line 1

Line 2

Measurement Lines and Proportions

Example

Without measuring the line, describe how long each one is in relation to the other.

When sketching objects, all the lines that make up the object are related to each other by size and direction. For a sketch to communicate effectively it must be drawn in the same proportion.

Line 1

Line 2

When sketching, you do not use a measurement scale.

Creating multiview sketches

Creating Multiview Sketches


Design process

Multiview Drawing

A multiview drawing is one that shows two or more two-dimensional views of a three-dimensional object.

Multiview drawings provide the shape description of an object. When combined with dimensions, multiview drawings serve as the main form of communication between designers and manufacturers.


Multiview sketching technique

Width, Depth, and Height

All three-dimensional objects have width, height, and depth.

Width is associated with an object’s side-to-side dimension.

Height is the measure of an object from top-to-bottom.

Depth is associated with front-to-back distance.

Isometric Pictorials


Isometric sketches

Isometric Sketches

Isometric views portray objects in a true 3d perspective.

Approx. 30 degrees

Approx. 30 degrees


Design process

Draw a 3 x 3 x 3 cube on your regular graph paper.

Does it look like a Cube?


Design process

Look at this for a minute.

Do you see triangles or 3d boxes?


Design process

All lines must be drawn in 1 of 3 directions.

Can you see the pair of shoes in the cubby hole?


Design process

Can you see the 3 surfaces here?


Design process

Can you see the flat surfaces on this sketch?

Sketch this in the top corner of your paper!


Design process

Step #1: Constructing The Box

They did NOT count the squares correctly on THIS drawing between the given figure and the one they drew.


Design process

Isometric Sketches

Step #2:Use points and construction lines to identify surfaces that are not parallel to the faces of the box.


Design process

Step #2: Outside Faces

They did NOT count the squares correctly on THIS drawing between the given figure and the one they drew.


Design process

Isometric Sketches

Step #3:Trace out the visible edges of the part with thick, dark object lines.


Design process

Step #3: Object Lines

They did NOT count the squares correctly on THIS drawing between the given figure and the one they drew.

Block technique

Block Technique

  • When sketching an object, visualize the object surrounded with an overall rectangle. Sketch this rectangle first with very light lines. Sketch the proper proportion with the measurement-line techniques.

Think of a

BLOCK of Styrofoam


Block technique1

Block Technique

  • Cut sections out or away using proper proportions as measured by eye, using light lines.

  • Finish sketch by darkening

    Lines and erasing unwanted

    Lines.

Cut Away 1st


Design process

  • Before you open Inventor:

    • In your “My Documents” folder, make a new folder and call it Engineering.

      Save everything we do in that folder!!

Line conventions

Line Conventions

Dimension Line

Dimension Line

  • Dimension Lines: Lines that are used to show distance.

  • Arrows are drawn on the ends to show where the dimension line starts and ends.

  • The actual distance is usually located in the middle of this line to let you know the distance being communicated.


Line conventions1

Line Conventions

Extension Line

Extension Line

  • Extension Lines: Lines used to show where a dimension starts and stops on an object.

  • Used with dimension lines to properly dimension an object.

  • The line is 1/16” away from the part as to not get confused with the object lines.


Line conventions2

Line Conventions

Leader Line

Leader Line

  • Leader Lines: Leader lines are used to show dimensions of arcs, circles and to help show detail.
