How do Engeneers design products?

Question

Engeneers design products for the use of other products today eneneers are deigning an most inovasive products for the use of everydays use like a drill is the use for nails and making holes in wood and lasers are the usefull ways in surgeries to enable the surgeons to find things during the surgery lamps are use for lights and light bulbs and moderen way of everyday use machines are used for many industrial products and medical products hosptals use them for the patients health conditions so as many ways engeneers designing products for the use of other products

Answer 1

Engineering design is a complex process and requires lots of thinking do to be done before you actually come out with a product. Let me tell you about the design process in simple terms. You have three major areas in design:
1. Developing a totally new product.
2. Modifying a product that's existing already
3. Reverse Engineering, or developing a design from a product that already exist and doing further changes to the design.

Developing a new product involves coming out with the solid model of the part using a good CAD tool like Pro-E, Unigraphics, or SolidWorks. We need to also choose the right CAD tool for your application. In the next stage you do the stress analysis on the part to see how the part behaves at different loading conditions. There is a technique or method called Finite Element Analysis(FEA) which is mainly used by major designers. We also have softwares for FEA to make things easier for us.

In the next stage we develop prototype of the solid that we arrived at and the purpose of the prototype is to test how the part behaves under practical conditions. If the prototype is good, we proceed with the actual manufacturing of the part.

After using a part for some time we get to know about the mofications that we can make on the part and this can be done only by market analysis of the part or the assembly which carries the part and it's performane at user's end. If your part isn't good, the customer will naturally go for your competitor's part which has a better design. Now you get back to your part model and modify it suitably.

Reverse Engineering is one where you're starting to design a product that already exists. You get a part, study it's dimensions and come out with the design for the part. You further modify it to make it much more functional than the part that you started with and produce the part.

I hope I'm clear with the basics of Product design. Engineering design is like an ocean and can never be explained in simple terms.

Answer 2

An Engineer has to find a solution to a problem keeping in view the available resources and has to ensure (by applying his engineering knowledge) that the solution is safe and is economically and practically possible.

Answer 3

you take what already exists and add to it. you have to have a good imagination based upon things you know will work.
