The automotive industry continues to be a hotbed of patent innovation. Activity in vehicle electric insulation is driven by increasing adoption  of electric vehicles (EVs), rising demand for lighter, more durable, high-temperature, and flame-retardant materials, and growing importance of technologies such as flexible polyimide film coated with metal, and Kevlar fiber and self-healing insulations. These technologies are still in development, but they have the potential to revolutionize the automotive industry. 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: vehicle electric insulation.

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 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

Vehicle electric insulation is a key innovation area in automotive

Vehicle electric insulation refers to the process and materials used to protect electrical components and wiring in vehicles from external factors such as moisture, water, and mechanical damage. It involves the use of insulation materials and techniques to ensure reliable and safe electrical connections and prevent short circuits or malfunctions due to environmental conditions.

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 vehicle electric insulation.
