There are times when we can learn much more by taking an object apart than by putting it back together from scratch. This perspective is what reverse engineering proposes, a process that aims to solve problems or provide improvements to a product or service by understanding how it works once it is built. It is a kind of ‘game’ in which the objective is to understand the construction completely backwards.
It may seem like a somewhat strange positioning, but the results are often astonishing. In fact, reverse engineering plays a crucial role in many areas and has very interesting applications. Do you want to find out how it works and where it is used?
What are the origins of reverse engineering?
When we use the term reverse engineering, it may seem like we are talking about the latest invention or the new way of doing research, but the curious thing is that the entire process of understanding a construction has been with us practically since we became humans. This method has allowed our species to understand the dimensions of an object and then reconstruct it, both to create a copy and to perfect it.
We can go to almost any point in history and find traces of its earliest uses. In Rome in 264 BC, for example, a Carthaginian quinquereme was reverse-engineered to build and optimize a Roman fleet of 300 ships in just 3 months, outperforming the Carthaginian fleet in both numbers and complex naval maneuvers.
The difference that we can see in its use is with the advancement of technology and industries. Although its initial purpose was basically military, today it is useful in many other fields, including manufacturing. In fact, over time it has not only been applied to other sectors, but manufacturers themselves have also begun to use the technology they have available to measure objects and import them into CAD software for 3D modeling.
This is not the only advance that has been added to reverse engineering, as we can also find coordinate measuring machines (CMM), probing systems and articulated arms mounted on robots. In this way we are able to get rid of any problems related to a more manual method. However, when choosing 3D technology we must take into account the required tolerance levels, data density and speed, part characteristics, line of sight and ease of use of the device.
Its recurring use is due to the precise, reliable and repeatable results it offers, since, although other technologies can also provide them, 3D is much faster and easier to use. In addition, it also allows 3D data to be acquired from a part directly in the workshop.
What is it then?
We now understand the origin of reverse engineering and how it has actually been with us practically since the dawn of our species. Ultimately, this process seeks to understand the components of an already created object, how they interact with each other, and what their manufacturing process is. That is why this technique has so many current applications, because it can be used to understand the inner workings of an object and, in this way, improve it.
As we have said, the first industries to be created already used it to copy elements of older human creation, but it is current technology that has made reverse engineering shine and offer everything it can give us. In fact, it is widely used, for example, in hardware and software for computer applications on many platforms.
The best way to understand what reverse engineering is about is with an example, in this case a true and historical one. We only have to look at the Enigma machine and how people tried to understand its operation by breaking it down to analyse its construction, circuitry and elements.
How to use?
Since reverse engineering involves ‘disassembling’ to understand how the parts that compose it relate to each other or if they could fit better in another way, what we have to do is ‘go backwards’ to follow its process:
Identification. As in any process, the first thing we must do is determine what we are going to analyze the object in question for, that is, for what purpose. It will be time to decide what information is needed (design, operation, materials, etc.) according to our purpose and the element in question.
Gathering information. The next step is to gather as much information as possible about the object. This includes manuals, diagrams, technical specifications, etc., as well as, of course, the physical object itself for analysis.
Disassembly. Now it’s time for the fun part, systematically taking it apart, documenting each step with photos, notes, and diagrams. As we slowly take it apart, it will be necessary to identify and label its individual components to keep track of all the components.
Component analysis. Now that we have the elements that form the object of our reverse engineering analysis, we will have to study each component to understand its function and how it interacts with the others. Everything must be measured and the materials and manufacturing techniques used must be identified.
Modelling and recreation. As we have mentioned above, we can use current technology to create digital CAD models based on the measurements and observations we have made and simulate their operation with specialized software.
Comparison and validation. Now that we have a mock-up in the virtual world, we can compare it to the original object to ensure that it is accurate. Testing will be needed to verify that the recreated model works in the same way as the original.
Documentation and improvement. Reverse engineering is used to understand how an object works, recreate it and make improvements. After studying it, we must document all the findings, including diagrams, models and notes, and identify possible modifications.
Application of knowledge. Now all that remains is to use the information gained to improve the original design, create new products or develop maintenance solutions.
Benefits
Understanding how it was built can offer us a great number of advantages, as we can recreate it and make a practically exact copy. However, this is not the only advantage we can gain from this process:
- Improving product design. It allows manufacturers to study existing products to understand their design and performance. This makes it much easier to identify areas for improvement in efficiency, functionality and quality and to offer improved versions of the product or to develop new products based on information obtained from successful designs.
- Repair and maintenance. Facilitates the repair and maintenance of obsolete products or those lacking technical documentation. By breaking down and understanding the product, engineers can identify the necessary components and their function, useful for equipment that is no longer in production.
- Innovation and product development. One benefit that is often overlooked is that it provides a source of inspiration. By analyzing existing products, you can identify new ideas, features, or approaches that you can bring to other products, encouraging the creation of those that meet market needs.
- Cost reduction. By understanding how products are designed and manufactured, companies can find ways to produce them more economically (identifying alternative materials, more efficient manufacturing methods, etc.).
- Competitiveness in the market. It allows companies to remain competitive by adopting and improving the technologies and designs of their competitors. If we understand their creations, as a company we can develop strategies to overcome or integrate them.
- Compliance with regulations and standards. It helps ensure that products comply with industry regulations and standards. By analyzing and understanding existing ones, we can ensure that our products meet legal and quality requirements.
- Development of technical documentation. Generate detailed technical documentation for products that lack it. This is essential for repair, maintenance and upgrading products, especially those that have been in use for a long time.
- Education and training. It is a valuable tool for the education and training of engineers and technicians. By studying and breaking down existing products, students and professionals can gain a deep understanding of design and manufacturing principles.
What industries use it?
Manufacturers from all types of sectors take advantage of the power of reverse engineering to optimize their production, gain a competitive advantage and reduce costs. Some of those who have jumped on the bandwagon of this process and who are getting the most benefits from it are:
