Design

Design is regarded by many as the core problem-solving process of technological development. It is as fundamental to technology as inquiry is to science and reading is to language arts.

Define Design:

An interactive decision-making process that produces plans by which resources are converted into products or systems that meet human needs and wants or solve problems

Define Design Brief:

A written plan that identifies a problem to be solved, its criteria, and its constraints. The design brief is used to encourage thinking of all aspects of a problem before attempting a solution. This may also be referred to as the Design Envelope.

Explain why we use Design Principals:

Design rules regarding rhythm, balance, proportion, variety, emphasis, and harmony, used to evaluate existing designs and guide the design process

Define the Design Process:

A systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve a problem or satisfy human needs and wants and to narrow down the possible solutions to one final choice.

Define Design Proposal:

A written plan of action for solutions to a proposed problem.

Designers are driven to develop products that are creative through inventions and innovations that show resourcefulness utilizing their ability to visualize and think abstractly along with considering several solutions for the same problem. Ideas are stimulated by our personal senses as they relate to the elements of design. These ideas are processed by individuals and incorporated into new products. Designers work through a collaborative effort to achieve the best possible solution for new products and systems. Designs are developed through an ongoing process of evolution that allows a product to improve over time.

List the 3 concepts you need to consider when you are designing a message.

  • Audience
  • Content
  • Format


List the 7 Principles of Design and describe each one.

  • Balance-
    • Balance involves determining the visual weight of an object or image in either formal symmetry or informal symmetry.
  • Unity-
    • Unity refers to the ability to make components of a design have agreement with no elements out of place or seem as they do not belong together.
  • Proportion-
    • Proportion distinguishes the size relationship of various parts of the project or graphic as they relate to the finished product.
  • Harmony-
    • Harmony is utilized to add rhythm and allow the viewer to see items in an agreeable manner.
  • Emphasis (Contrast)-
    • Contrast establishes a point of emphasis to draw the viewer's eye in on specific elements of a graphic or product.
  • Rhythm-
    • Rhythm is the reoccurrence or repetition within a design that gives it the appearance that movement is taking place.
  • Variety-
    • Variety is used to add elements of interest to a graphic or product to gain interest in a graphic or product.

List the 6 Elements of Design.

  • Line
  • Color
  • Shape
  • Space
  • Form
  • Texture


Invention is the process of coming up with new ideas, design is concerned with applying these ideas.

Innovation is an improvement of existing product, system, or method of doing something.

Creativity is the ability to think outside the box and imagine new possibilities

Experimentation is the form of technological problem solving that resemble most closely the methods that scientists use.

The design process should be utilized to develop productive, useful products that may be advantageous to society in many areas such as communications, transportation, manufacturing, construction, energy and power, and biotechnology systems. The design of products as they relate to the systems of technology will ultimately change over time by the way individuals weigh the factors of a product's ability to be utilized. These factors include:

Safety - to comply with codes and regulations so as to provide safe operation of products by the developer and the consumer.

Reliability/functionality - the process of a product working properly utilizing proper materials within the development constraints

Economic considerations - development of jobs and products for the marketplace for individuals to purchase and pay tax on.

Quality control - requires information feedback related to measurement tolerances and specifications to assure proper production of products.

Environmental concerns - developing products that are produced in harmony with our environment and recyclable.

Manufacturability - the ability of a product to be produced through feasible means and meet a need using available materials and resources.

Maintenance/repair - products produced with the intention of long life and low maintenance along with simple field replacement units.

Ergonomics - the study of workplace equipment design or how to arrange and design devices, machines, or workspace so that people and things interact safely and most efficiently.

Design firms around the world are striving to compete with the ever-changing global marketplace. The human capability to initiate invention and innovation of new creative products and systems are evident in our world. Development of new products to fill our needs and wants will continue to change the way we think and act within our environment.

Benefits vs. Consequences of New Designs As one develops new products and systems in this ever-changing society, he or she must weigh the benefits of the design against the potential hazards of it. The benefits of a new product must outweigh the hazards. For example, the development of energy sources that create pollution (such as fossil fuels and hazardous waste) must be compared to the development of energy sources that have clean emissions, as our society no longer accepts pollution as a trade-off for lower priced energy sources. Our society today is more environmentally conscious than ever before. Earth is our home—we must protect and preserve it for future generations.

Our current observations and discoveries about the design of genetic codes (such as DNA & RNA) are leading to many new, amazing rewards that will indeed change our future. Our ability to implement preventive measures for many birth defects is only one of the benefits. Another breakthrough medical advance is the ability to design agricultural products that are utilized in diet and medications for the treatment of a variety of health-related conditions. We now have the ability to create artificial devices that extend our lives by repairing or replacing certain parts of the body. The designs of new medical technology, equipment, and the development of many of the medications over the years have saved countless lives. Medicines to fight off diseases, such as polio, measles, and small pox, offer one hope in the current race to cure AIDS, cancer, and the numerous other incurable diseases that plague our world today. Biotechnology is applied in advances toward the development of products that produce higher yields to feed the ever-growing world population. New developments in caring for our environment and developing specialized products have resulted in spin-offs such as pharmaceuticals, energy sources, and control of our environment, which help our world every day.

What two non-computer generated items are used in the beginning stages of Desktop Publishing.

The design and production of graphic arts typically begins with two non-computer generated items
  1. Thumbnail sketches generally show choices for possible page layouts.
  2. The rough layout or mechanical layout shows the dimensions, size and locations, of all of the elements, text, and images on the page.
More often now than in the past, designers are not physically pasting elements onto the camera-ready copy of the design. Instead, most of this so-called, paste-up is done solely on the computer. Computers are also used in generating film and printing plates without the use of process cameras. Typical desktop publishing software that is involved in the graphic design or pre-press process includes PageMaker, and Quark Express. Color separations and other digital photographic processes are accomplished with graphic design software like PhotoShop and Corell Draw.

For the composition of landscape and other non-portrait photographs, generally the rule-of-thirds is followed. It means that the photograph is composed of two-thirds sky and one-third ground or visa versa depending on what is the most interesting. Students often leave too much headspace and shoot from too far away when composing interest shots. Lead space should also be included if a subject is facing a certain direction or is moving in a particular direction. Portraits should be shot close up without too much headspace.

What is a storyboard used for?

The storyboard helps people visualize each shot with regard to lighting requirements, sound, dialog, etc. Planning shoots depends on the requirements that are specified in the storyboard.
