The automotive industry continues to be a hotbed of patent innovation. Activity in selective catalytic reduction (SCR) mixer assembly is driven by factors such as emissions regulations, fuel economy improvements, cost-effectiveness, and consumer demand, and growing importance of technologies such as helical baffles, ceramic composite materials, laser cutting, and computational fluid dynamics (CFD) modeling to enhance efficiency, reduce emissions, and improve air quality. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in automotive: SCR mixer assembly.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

300+ innovations will shape the automotive industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the automotive industry using innovation intensity models built on over one million patents, there are 300+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, integrated multi-motor drivetrains, electric power steering (EPS), and post-collision handling are disruptive technologies that are in the early stages of application and should be tracked closely. Variable compression engines, V2V distance monitoring, and turbocharger shaft bearings are some of the accelerating innovation areas, where adoption has been steadily increasing. Among the maturing innovation areas are kinetic energy recovery system (KERS) and plasma-jet ignition, which are now well established in the industry.

Innovation S-curve for the automotive industry

SCR mixer assembly is a key innovation area in automotive

An SCR  mixer assembly is a system that reduces the level of NOx emissions in exhaust gas by injecting a reductant, usually a urea solution, into the exhaust stream. The assembly mixes the reductant and the exhaust gas, which promotes the hydrolysis of the urea solution and the creation of ammonia, a necessary component for NOx reduction.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 30 companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of SCR mixer assembly.
