From steam engines to computers: Historical context for Industry 4.0

Calling something a revolution is a huge claim. The truth is that many “revolutions” we’ve heard about have not lived up to the hype.

Then, what makes Industry 4.0 a true revolution?

It is the capacity of Industry 4.0 technologies to disrupt existing orders. Technologies like blockchain, artificial intelligence, etc., all have the potential to undermine and massively transform core institutions. 

To put this into context, let’s take a brief look at the previous three industrial revolutions.

i) First Industrial Revolution – Mechanization

During the late 18th century in Britain, the first industrial revolution ushered in a new era of mechanization, replacing human and animal power with water and steam power. This revolution transformed society with the advent of trains, mechanized manufacturing, and lots of smog.

ii) Second Industrial Revolution – Mass production

A century later, the second industrial revolution brought technology to industries that resulted in new forms of energy, including oil, gas, and electricity. The introduction of these new power sources, along with more advanced telephone and telegraph communications, brought mass production to manufacturing processes.

iii) Third Industrial Revolution – The digital revolution

The third industrial revolution, which began in the mid-20th century, gave rise to computers and telecommunications. This revolution also opened the door for new technologies that allowed for advancements in biotechnology and space exploration.

These three were all called ‘revolutions’ because the innovation behind them didn’t just slightly improve productivity and efficiency, it completely revolutionized how products were created and how jobs were performed.

Now, sometime in the last decade, manufacturing entered a period of transformation. New industrial technologies started quickly emerging, like cloud computing, artificial intelligence, the Internet of Things, big data analytics, 3D printing, cyber-physical systems, etc.

Together, these technologies inaugurated a Fourth Industrial Revolution. This revolution, also called Industry 4.0, is changing manufacturing at a pace and scale similar to the invention of steam power or electricity. Let’s explore this revolution in more detail in the next section.

Well, we are glad to tell you that not only companies have implemented them successfully they are being benefitted from them every day. 

Let’s spotlight a couple of real-world examples to show you that Industry 4.0 is already a reality.

A. Bosch Software: When data analytics meets manufacturing

Bosch Automotive Diesel Systems Co is a consumer goods company located in Wuxi, China. It is one of the most important bases of the Bosch Group. This company has combined IIoT and Big Data in order to drive the digital transformation of its factory in China.

And how exactly is it doing it? It has connected its machines to monitor the overall production process at the core of its factory. 

  • Sensors are embedded into the machines in the factory that are used to gather information about their cycle times and conditions.
  • Modern data analytics tools analyze this data in real-time and notify the working staff when any production bottlenecks are found.

Thus, it can now easily predict equipment failures, enabling the factory to schedule maintenance operations well before any failures occur. As a result, the factory is able to keep its machinery working for extended periods of time.

The company states that using data analysis in this way has contributed to more than 10% output increase in certain areas whilst improving delivery and customer satisfaction.

Ultimately, having more knowledge about the plant’s operations helps the entire organization make decisions that are better and faster, which enables it to minimize equipment downtime and optimize production procedures.

B. Team Penske: Racing to win with digital twins

Team Penske, an American pro racing team, wanted to speed up the race car development process. It partnered with Siemens in 2018, gaining access to advanced digital design and simulation solutions – including digital twins.

This gave Team Penske engineers a virtual testing ground for developing new components and enhancing vehicle performance before they ever touched the actual vehicle.

  • A race car digital twin was built by fitting sensors onto a real car. 
  • These sensors gather information on the engine control, tire pressure, and wind speed, which is then used to create a virtual car model.
  • This model enabled engineers to evaluate different design configurations and make efficient, data-driven design changes at a very rapid pace.

This ultimately helped Team Penske to carry out a cheaper, more resource-efficient product testing process. As a result, it completed the best racing season in the team’s history, was able to deliver parts to the track in less time, and achieved the 200th IndyCar and 500th team wins.

Both of these examples illustrate how organizations are integrating the latest technologies to enhance the performance of their operations. Hopefully, now you are able to get an idea of how much the world will change with the implementation of these awesome technologies.
