Challenge: Aquabar approached Cubik with an idea for an inflatable flood defence system. They had a simple mechanical rig that they inflated with an electric tyre inflator. Aquabar wanted a proof of concept solution that would show the possibility of automated inflation. They wanted to activate the device automatically when the property becomes under threat from flooding. It also had to enable the user to deflate the device under certain conditions I.e. when the property is no longer under threat. The unit had to be battery powered in case of a power cut, but also provide a method of recharging the battery once power had been restored.

Cubik designed and built 2 technology demonstrator units, using a rapid prototyping PCB as well as various standard components combining these items with a Commercial off the Shelf enclosure. The unit uses an external float switch that is mounted to an exterior wall to detect rising flood water; the Aquabar then automatically inflates protecting the user’s home. The pressure is monitored continuously and will continue to keep the Aquabar “topped up” in case of air leaks.  After the flood has receded the Aquabar can be deflated by the user.

Results: Aquabar received the 2 demonstrator units and have been using them to highlight the products capabilities to several interested parties. Cubik will continue to assist Aquabar with their requirements and hope to develop a bespoke solution in the later part of 2013.




Adrian Schmieder of HiETA commented: “Cubik’s quick turn-around of a functioning PCB has sped the delivery of the project and enabled me to focus on areas of the project in which HiETA has expertise.  The project is a great success and produced valuable information even from its first use.  I am very impressed with the support Cubik provided me throughout the project, from initial concept through to PCB delivery.  I will not hesitate to engage with them again as future PCB projects arise.”


Speaking about the collaboration between Inductosense and Cubik Innovation, Founder and CTO Dr Chenghuan Zhong (Bamboo) stated: "It was great working with the knowledgeable and experienced team at Cubik Innovation. They always provide full support as well as useful and thoughtful advice to us, helping us find solutions for really difficult problems."


Geoff Jones, Aquabar Inventor: "It was a pleasure to work with Cubik on our project. Paul and Sam understood the concept at one meeting, and produced a solution filling the brief within two weeks which has enabled us to find a potential partner. We will certainly use Cubik for our production units later in the year, Many thanks."

Paul Davey, Associate Professor (SL) Plymouth University: "If you need a prototype developed to a high standard and on time you would be hard pushed to find someone better. They have highly trained, experienced engineers who get the job done."
