Reverse Engineering is an approach or method for determining the design of existing devices or systems. You can use it to learn the design process or you can go for a step to redesign the process. Whereas, reverse engineering is used to realize the methods and materials to create something. When there comes a statement that why do engineers perform reverse engineering on products then it must be kept in mind that reverse engineering services are performed by engineers on products to realize the methods or designs to create something. Furthermore, engineers go for analyzing the process of reverse engineering because they wanted to design or redesign the devices or systems.
Reverse engineering is a process that takes a device, system, or software program apart and starts determining the details and working of the product, it is because to construct a new device that has the same process without copying from the original. Whereas, reverse engineering could be applied to the design of the same products and learning from the defects of existing designs that are known as the objective of reverse engineering. Reverse engineering is a part of the redesign procedure, where a product is detected, observed, analyzed, and tested according to its performance.
As we know that engineering is known as the profession in designing, constructing, maintaining the products, devices or programs. There are two types of engineering at a higher level: one is forward engineering and the second is reverse engineering.
Forward engineering is the process of going from logical designs to physical execution of the system. there may be some part without practical details that include drawing, electrical properties, deprived of any engineering data, etc.
Whereas, without the process of copying an existing component or product without the help of drawing, or computer model is known as reverse engineering.
Furthermore, reverse engineering could be viewed as the process of examining a system:
It usually identifies the component of the system and creates the physical representation of the device or product.
Reverse engineering is common in software engineering, products, chemicals, mechanical designs, entertainment, etc. if we talk about that when a machine comes into a market, some of the constructers will buy it and learn how it was built and it is working. Whereas, a chemical company uses reverse engineering to defeat a rival’s construction process.
Here are some few reasons for reverse engineering a product:
Here are some bad features of a product that must be designed out.
Reverse engineering allows the copying of an existing product by picking up the material properties, features, and physical dimensions, etc. if you wanted to go with reverse engineering, you first need to have a well-planned life-cycle and cost or benefit analysis should be accompanied to justify the reverse engineering projects.
An example of reverse engineering starts from a physical product, then you have to obtain dimensional details, create a 3D model, examine the model with a physical model, create manufacturing drawing, and process of manufacturing. It includes Air-conditioning and refrigeration systems, Mechanical seals, Air conditioning system dryer housing assembly, High-temperature washer assembly, or Bleed-air valve components, etc.
It is useful when the original design has been lost or not existed. Whereas, some of the bad features of a product must allow to designed out. It is important to analyze the good and bad features of the competitor’s product.
It is stated that Reverse engineering starts with the product and works with analyzing the design process to arrive at a product definition statement(PDS). Hence, it helps to uncover the information as possible about the ideas of the designs that were going to use to produce a product.
