Fundamental Design Principles

  • Occam’s razor

In general, Occam's Razor states that the simplest explanation is usually true. In engineering, using Occam's Razor means to do something in the simplest manner possible.

  • Lateral thinking

It is a mental process of generating ideas and solving problems not directly, with a frontal attack, but by evaluation of a situation and approaching problem from a non-standard direction.

  • Engineering design practice

Engineering design practice depends on two factors:

  1. Background of the designer;
  2. Available technology.
  • Units and measurements

In general, engineers in the North America use English system, and in Europe - metric.

  • Off-the-shelf components in design

From the Occam’s razor we know that design should be as simple as possible. Therefore, a good practice is to find as many off-the-shelf parts as possible.

  • Modular design

The principle of modular design allows end user to customize, repair and reuse products by simple replacement of a faulty component.

  • Freezes

In engineering design freezes mark the end points of various development stages.

  • Accuracy, repeatability, and resolution

Accuracy – indicates how close a measured value is to the real quantity of what is being measured.

Repeatability – describes how well a system can reproduce an unchanged outcome.

Resolution – is the smallest variation the system can display.

  • Reference features

In engineering drawing, a reference is a relation with the datum from which the measurements are made on the part.
