Welcome to Design Verification

Are you a Mechanical engineer who works in any Industry and also feels like having expertise in your core area of working?

Have you ever come across making any Technical specifications for your products being manufactured or to be procured?

Have you ever seen the failure of any Mechanical structure or system failure under certain loading conditions and tried to do find out the exact reason of failure?

Have you ever tried to find  out how materials behave under different loading condition and bending moments affect structures, and what causes bending?

Do you feel that all the Technical questions asked by the people or your colleague shall be explained by you with all the logical and practical approach?

If you are still finding the solution to the above problems, You have landed in a right place.

I had such problems, and that’s why I started to share my experience and practical knowledge related to design and manufacturing in a blog form.

Before we dive into the steps that will help you to become a successful Mechanical Engineer, let’s take a look at what Mechanical engineering really is.

Mechanical engineering focuses on the design, manufacturing, testing, and improvement of mechanical systems, which are used in almost any industry you can think of.

On this platform, we will understand the intuitive side of Mechanical design, manufacturing, testing, and improvement of mechanical systems and discuss the Logical and practical aspects at the highest level.

Before proceeding, let us discuss How Mechanical designer proceed with the design and development of a product.

Since childhood, we all have seen the development of many comfort-providing products. Over the period of time, numerous development has been done in field like Transportation, communication, Energy, etc. For example, think about the era when we used to travel by BULLOCK CART and then we moved to BUS or Rail and so on. You can also consider the mobile handset that we used around some 15-20 years back. If we compare it with today’s handset we can find many more changes in terms of weight, size, Material, and so on.  Similarly, you can find many products around you which got changed in many aspects like Material, shape & size, cost, and comfort point of view. Now, the question which comes to mind is “What was the need for development?” and ‘How come all these development of products became possible? The answer to the first question can be given in one line that is, the Development of a product is done to provide comfort to the user and for the survival of an organization in the competitive market. For the answer to the second question, you will have to first know about the “Design and Designer” and their Approach to the development of any product. A design is a method to create an Idea or concept or specification having all the technical details including Material & Dimensions for the manufacturing of a feasible & economical product. These all are based on the experience and feedback of the users. A person who performs these tasks is called A Designer. Now, let us discuss the approach for the design of any product. Look around yourself and find out all the products that you and your family members use. For example, A Bicycle. You might have seen a Bi-cycle for an Adult as well as for a kid. Try to find out the answer to the following question.

1. Why do you use your Bicycle?
2. Can any Adult use the kid’s Bicycle? if not then why?
3. How many persons can Sit in your Bicycle? If the number is limited then why?
4. Why it’s not made of plastic?
5. Can you drive it in a slippery area? If not, then Why?
6. Most of the parts like the handle, crossbar, frame, etc. are made from pipe, not of any angle or C-section. Why?
7. Why Some of the Bi-cycles are costly?

There are many questions that can come to your mind and once you find the answer to all the above questions in an engineering way you will be able to understand the approach of a designer for the development of any product. Before designing any product, a designer always explores the following things related to it:

1. Requirement
2. User
3. Load/Weight/Force that it’s going to bear during operation
4. Material that can be used
5. Environmental or working conditions for its use.
6. Aesthetic look along with strength 
7. Ease of manufacturing
8. Handling
9. Cost

All the design involves a detailed calculations based on some basic formulae that we have studied in our engineering colleges.
