Key Applications of IoT in Manufacturing
So how are manufacturers actually using IoT to transform their operations? Here are some of the key applications:
Predictive Maintenance
One of the most impactful applications of industrial IoT is predictive maintenance. Smart sensors continuously monitor the condition and performance of production assets to detect potential issues before they result in costly unplanned downtime. Advanced AI algorithms analyze the sensor data in real-time to predict when maintenance will be needed based on factors like vibration, temperature, and runtime.
Armed with these AI-driven insights, manufacturers can optimize their maintenance schedules and replace parts proactively to maximize equipment uptime and useful life. Studies have found that predictive maintenance can reduce machine downtime by 30-50% and increase machine life by 20-40%.
Connected Factory
IoT is also enabling manufacturers to create fully connected, self-optimizing “smart factories.” By connecting machines and other assets across the factory floor, manufacturers gain real-time visibility into every aspect of the production process.
Factory workers are equipped with mobile devices and wearables to connect them to the production line. Environmental sensors monitor the factory conditions to ensure optimal settings. All of this IoT data is collected and analyzed by a centralized factory management platform to orchestrate and optimize the entire operation.
The results are powerful. Smart factories can operate with much greater flexibility and agility, seamlessly adapting production to changes in demand or conditions. Overall equipment effectiveness (OEE) increases while cycle times shrink. Product defects and waste are minimized. Ultimately, the connected factory makes it possible to achieve the long-sought goals of “just in time” and “lot size one” manufacturing.
Automated Quality Assurance
Ensuring consistent, high quality products is an essential task for any manufacturer. Here too, IoT is providing a major assist. Connected cameras and sensors can monitor products at every stage of the manufacturing process, spotting defects in real-time and enabling much faster root cause analysis and corrective action.
In addition to visual inspection, IoT quality assurance solutions also typically incorporate non-visual sensors (e.g. weight, conductivity) as well as functionality tests conducted by connected devices. All inspection data is fed into an AI-powered quality management system that ensures only products meeting specifications make it through to the end customer.
The impact of IoT-based quality assurance is substantial. Defect rates can be reduced by 90%, leading to multi-million dollar annual savings for large manufacturers. And by reducing defects and warranty claims, IoT helps protect the brand’s quality reputation.
Connected Worker
While much of the discussion around industrial IoT focuses on machines and automation, the technology is also transforming the role of human workers on the factory floor. IoT-enabled connected worker solutions equip factory workers with an array of smart devices and wearables – smart glasses, mobile devices, smartwatches, location badges, etc. – to augment and enhance their work.
These connected worker devices can deliver information and guidance to help workers complete tasks faster and more accurately – step-by-step visual instructions, checklists, diagrams and other AR content. The devices also capture data on worker activities to optimize training, workflows, and ergonomics.
From a safety perspective, wearables monitor worker health metrics and alert of any dangers, while location tracking ensures workers are only accessing equipment they are authorized and trained for. The end result is a more skilled, productive and safe manufacturing workforce empowered by IoT technology.
Adaptive Robotics
As costs have fallen and capabilities advanced, connected robots have found rapidly increasing adoption in manufacturing environments. Industrial IoT robotics solutions go beyond traditional single-purpose robots to create flexible, adaptive robotics systems that can be quickly trained and deployed for a variety of applications.
Using machine learning and computer vision, these robotic systems can adapt to real-world variability and learn by example. A factory worker can train a robot simply by walking it through a task, rather than requiring specialized programming. The robot’s learning is then shared with a network of connected robots.
These adaptive IoT robotics solutions dramatically lower the cost and expertise barriers to implementing automation for manufacturing tasks. Manufacturers can deploy flexible, multi-purpose robots that can be efficiently re-trained and re-deployed as needs change. IoT is making robotics accessible and cost-effective for manufacturers of all sizes.
Challenges of Industrial IoT Adoption
While the benefits of IoT in manufacturing are clear, there are also challenges manufacturers must navigate in adopting the technology:
| Challenge | Description |
|---|---|
| Integration with legacy systems | Most manufacturers have extensive legacy equipment and systems that were not designed for IoT connectivity. Integrating these assets can be complex and costly. |
| Data security concerns | With so many connected devices and vast amounts of data, IoT significantly expands the attack surface for cyber threats. Robust security is essential. |
| Finding the right talent | Implementing industrial IoT requires specialized skills in areas like data science, cybersecurity, and AI that many manufacturers lack. |
| Difficulty proving ROI | Manufacturers may struggle to build a compelling business case and ROI model for IoT investments, slowing adoption. |
