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.

80+ innovations will shape the construction industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the construction industry using innovation intensity models built on over 232,000 patents, there are 80+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, self-healing concrete, waterproof floor drains, and construction 3D Printing are disruptive technologies that are in the early stages of application and should be tracked closely. Smart glazing, regeneration control hydraulics, and floating breakwaters are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are wall surface temperature controls and embossed floor panels, which are now well established in the industry.

Innovation S-curve for the construction industry

Hydraulic slewing drive is a key innovation area in construction

A hydraulic slew drive is a mechanical component used in heavy machinery, such as excavators and cranes, that enables rotational movement of the machine's working components. The drive is powered by hydraulic pressure, which activates an internal hydraulic motor, causing the drive to rotate. The hydraulic slew drive is typically installed between the machine's body and the rotating component, allowing the rotation to occur smoothly and precisely.

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 10+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of hydraulic slewing drive.

Key players in hydraulic slewing drive – a disruptive innovation in the construction industry

‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Kobe Steel, Liebherr, Manitowoc, and Kawasaki are among the leading innovators in the hydraulic slewing drive space.

A recent innovation by Kobe Steel involves the use of a slewing control device that enables the system to detect breakdowns in the driving system. The device utilizes a mechanical brake, which generates enough torque to prevent movement of the slewing body when an anomaly has occurred, thus, acting as a fail-safe. The innovation has potential to improve the safety of operating machinery and avoid excessive damage to the machine.

In terms of application diversity, the leading companies are XCMG, Liebherr, and Manitowoc, while Hitachi, Sumitomo and Liebherr are the leading companies in terms of geographic reach.
