Every year, Australia produces some solid engineering and design ideas, but it’s not the only country to do so, and while we have a pretty strong entrant for the James Dyson Award, some of the competition is pretty impressive, too.

The winner of the Australian division of the James Dyson Award – Shan Shan Wang – did pretty well to beat out futuristic police helmet and avalanche-protective ski mask with her kid friendly oxygen tank, but it’s going to be interesting to see it go up against ideas from around the world, too.

Around 650 projects were entered into the Dyson Award, which seeks to find the best inventions and ideas from around the planet, with James Dyson judging the best and choosing the winner that shows the most amount of promise.

“Bold ideas, big or small, can solve significant problems,” said Dyson. “The entries into this year’s award, from young engineers and scientists around the world, all show promise but are only at the start of the long process towards commercialisation.”

Some of these ideas look truly remarkable, and will definitely provide Ms. Wang with some excellent competition, including one from New Zealander Jake Evill called the “Cortex.”

An evolution of the arm cast for when you have a broken arm, the Cortex is a 3D printed cast utilising the strong honeycomb structure.

The Cortex is printed out of recyclable plastic for the arm in question, and while it’s a tight fit, it also allows plenty of breathing thanks to the holes left in the structure, allowing the arm to be washed easily, as well as not getting too sweaty in warmer weather.

It’s not the only idea that impresses us, with a four-person team from America making a new type of exoskeleton arm for helping workers lift objects.

Called the “Titan Arm,” it was developed by Elizabeth Beattie, Nick McGill, Nick Parrotta, and Niko Vladimirov, and it will attach to a back using a brace and help enhance human strength, making it easier for workers lifting quantities of large and weighty objects.

Not only useful for that, the creators of the Titan Arm see it as a solution for people who need to rebuild muscle from injuries, or who may have disabilities.

Another American project is also a cool idea, and it’s for cyclists everywhere.

Developed by Kent Frankovich, “Revolights” are LED rings that can be attached to the inside of bicycle rims, with a lithium-ion battery powering the lights and an accelerometer working out when the lights need to be switched on.
