The construction industry continues to be a hotbed of patent innovation. Activity is driven by an increased focus on environmental sustainability and workplace safety, and the growing importance of technologies such as the Internet of Things (IoT) and robotics. In the last three years alone, there have been over 425,000 patents filed and granted in the construction industry, according to GlobalData’s report on Robotics in construction: smart toilet. Buy the report here.

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, polishing robots, robotic excavators, and autonomous worksite machines are disruptive technologies that are in the early stages of application and should be tracked closely. Welding robots, automated slurry-blast tools, and adaptive road milling rollers are some of the accelerating innovation areas, where adoption has been steadily increasing. 

Innovation S-curve for robotics in the construction industry

Smart toilet is a key innovation area in robotics

Smart toilets incorporate technology into the bathroom plumbing fixture, and can include features such as adjustable water spray systems for bidet facilities, automatic flushing, automatic seat opening and closing, lighting systems, and seat warming functions. Smart toilets can be environmentally friending, by reducing water usage and the use of toilet paper, and allow for greater accessibility for people with disabilities.

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 40+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of smart toilet.

Key players in smart toilet – 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’.
