Engineering Design tips for beginners

Faultless engineering exists only in theory. Everybody makes mistakes that even WD-40 cannot solve. Our engineers still tried to compile a comprehensive list to keep in mind when designing, to minimise the amount of those problems. Write them down and keep them in front of you at all times during the designing process. Cross out the demands that have been met and add new ones, if necessary. Keep it up to date.

Engineering Design tips for beginners

If you are having a hard time at coming up with good solutions. Many of them include great ideas that may aid you on the journey to a good design.

Build Your CAD Files Logically

This an important engineering tip. Use as few features as possible to build your parts. A shaft can be done using one command and a sketch (revolve) or multiple protrusions, followed by chamfers and radii. If your CAD program has a shaft feature (Inventor does), then use it. Your colleague will appreciate your considerate nature, if she has to redesign your part at a later time.

Design for Price

You may design the most beautiful machine ever but nobody will buy it, if the price is double of your competitor’s, unless the machine is a car. Check the prices of different solutions to compare and make choices accordingly.

Design for Beauty

If the customer is paying €40,000 for your machine or construction, he won’t want to get something that looks straight from the landfill. Looking good might be the edge in a competitive market. Turn to a laser or plasma cutting service to give smooth edges and trim down some unnecessary weight, in style.

Make It Modular

You might need to make another similar product. Look ahead to avoid cursing at a later time. Modular design will give you the option of only updating a part of the assembly, leaving most of it untouched. It also gives you the possibility to have more standard parts in stock, diminishing your delivery times.

Avoid Over-Dimensioning

Nobody wants to pay for unnecessary weight. Use Finite Element Analysis software to analyse the strength of the structure. Check those calculations manually. Optimise your design accordingly and choose the right type of metal for your application. A highly advanced way to tackle this point is by using CAD software with possibilities for creating models through generative design. This feature allows to minimise the use of material but also sets its own limits to the manufacturing technologies suitable for producing the part.
