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

Pneumatic door closers is a key innovation area in construction

Pneumatic door closers are mechanical devices that use air pressure to control the opening and closing of a door. They use specifically designed components such as pistons, cylinders, and valves to regulate the air flow and provide a controlled closing motion of the door.

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 construction companies, and up-and-coming start-ups engaged in the development and application of pneumatic door closers.
