In-person class cancellation and work-from-home / Annulation des cours en présentiel et télétravail. McGILL ALERT! Due to freezing rain all in-person classes and activities on Wednesday, March 11, will be cancelled. Staff are asked not to come to campus tomorrow unless they are required on site by their supervisor to perform necessary functions and activities. See your McGill email for more information.

ALERTE McGILL! En raison de la pluie verglaçante, tous les cours et activités en présentiel prévus pour le mercredi 11 mars sont annulés. Nous demandons au personnel de ne pas se présenter sur le campus demain, à moins que leur superviseur ne leur demande d’être sur place pour accomplir des fonctions ou activités nécessaires au fonctionnement du campus.

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.
