The automotive industry continues to be a hotbed of innovation, with activity driven by autonomous and connected vehicles, as well as the growing importance of technologies such as cloud computing and machine learning. In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Innovation in Automotive: Worm gears.

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 stabilising 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.
290+ 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 619,000 patents, there are 290+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, resilient spoke wheels, auto-transmission lubrication circuits, and ignition switching engines are disruptive technologies that are in the early stages of application and should be tracked closely. Engine purge actuators, electro-dynamic braking, and adsorptive vapour recovery system estimation are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are collision avoidance braking control system and direct injection type engines, which are now well established in the industry.
Innovation S-curve for the automotive industry
Worm gears is a key innovation area in automotive
Worm gears comprise a worm and a gear (sometimes referred to as a worm wheel), with non-parallel, non-intersecting shafts oriented 900 to each other. The worm is analogous to a screw with a V-type thread, and the gear is analogous to a spur gear. They are power-transmission components primarily used for high-ratio reductions to change the direction of shaft rotation.
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 20+ companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of worm gears.
Key players in worm gears – a disruptive innovation in the automotive industry
‘Application diversity’ measures the number of different applications identified for each relevant patent and broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of different countries each relevant patent is registered in and reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

JTEKT is a key player in the worm gears innovation. JTEKT engages in the production of worm gears that provide high reduction ratios and correspondingly high torque multiplication. JTEKT’s worm gears can also be used as speed reducers in low- to medium-speed applications. They are also more compact than other types of gear due to their reduction ratio, which is based on the number of gear teeth. Mando, Hitachi, Oiles, ZF Lenksysteme, and ThyssenKrupp are some of the other key players.
