Engineering can be a really exciting field to work in. All kinds of engineers need to be creative, original thinkers who are incredibly good at problem solving and this means that there is a huge demand for them in recruitment. To showcase exactly what engineering knowledge allows young people to get into, we’ve rounded up 10 amazing inventions dreamt up by engineering students across the planet.
#1 – Smart Needle
During surgeries and biopsies, needles are often required to perform tasks inside the body. However, standard straight needles are often difficult to manoeuvre around organs and bones to get to certain parts of the body and so surgery can be risky and time-consuming.
A team of engineering students at Temple University in Philadelphia addressed this problem with their invention – the Smart Needle. This needle was designed using a metal alloy called nitinol which is made up of nickel and titanium and has shape memory and super-elasticity. This means that the Smart Needle would be flexible and be able to move around obstacles in the body but it would resume its original shape following the surgery. Now that’s what we call sharp thinking.
#2 – Iron Man
An Indian engineering student has taken inspiration from the movies for his creation of a walking robot suit – a real-life Iron Man suit. It doesn’t fly but it can lift up to 330 pounds which is more than its own weight! Plus, the designer and builder of the suit, Vimal Govin Manikanden only spent $750 (roughly £578) on the creation. With existing walking-assist exoskeletons costing tens of thousands of dollars this invention could be the beginnings of a major step in progressing the use of exoskeletons in prosthetics.
#3 – Space Brewery
The Iron Man suit may not actually be able to fly up into space but the next innovation on our list is looking to do just that. Team Original Gravity are designing a kit that will be able to brew beer – on the moon. They are competing to win space for their machine on a lunar lander set to launch to the moon in December this year. If their proposal is selected, the cola-can-sized kit will be on the lunar lander when it blasts off and it will test the viability of growing yeast in outer space. Sadly, as the lander will be unmanned, no one will be able to drink the beer but this could mean future generations will be able to enjoy their favourite tipple on the moon – and we’ll drink to that!
#4 – Water Filter
If beer’s not really your thing, then perhaps a cool, refreshing drink of water would better fit the bill? Indian mechanical engineering student, Niranjan Karagi is addressing the struggle many Indians face in accessing clean water with his clever, portable water filter. While the NirNal filter may be small, it is also mighty; each one can filter up to 100 litres of water and purifies this water by up to 70%. Plus, the solution is extremely cost-effective with each filter costing only Rs 20 (roughly 24p)!
#5 – Electric Car
In China, supercar fan Chen Yinxi has used his experience in automotive engineering to build his very own electric supercar. Yinxi designed and built the Hainan Xiaohuohua car from scratch, using fibre-reinforced plastics from his father’s company and purchasing parts online. It doesn’t quite reach supercar speeds (its estimated maximum speed is just 18mph) but it’s certainly an impressive achievement for a student to build a working car from nothing.
#6 – Tiny House
The next student on our list took things one step further than building a car from scratch: University of Texas student, Joel Weber, has designed and built himself an entire house! With a total cost of just $15,000 (£12,000), Weber saved himself the enormous cost of renting a campus apartment (roughly $72,000 (£57,800) over four years) – and his home is pretty cool, too. The tiny house is built on a trailer to avoid size requirements in building codes but includes everything a single person home could need: bedroom, kitchen facilities, bathroom and, of course, a desk and work space.
#7 – Rollercoaster
If you’re looking for more of a thrill in your back garden than a tiny home on wheels, then Canadian teenager, David Chesney’s invention could be right up your alley. Chesney commandeered his parent’s back garden to build a 12-foot-tall and 92-foot-long rollercoaster! The Engineering student named the coaster ‘The Minotaur’ and it consists of 25m of track including two 3.6m drops. The best thing? He never has to wait in line for a turn!
#8 – Prosthetic hand
Meanwhile, a group of biomedical engineering students in Greater Cincinnati, Ohio, started a student initiative back in 2015 to build inexpensive prosthetic hands for local kids. The students use 3D printing technology to create plastic components which the team then put together and the prosthetic is delivered to the patient in roughly a week. Each hand costs only around $20 to make and this is made possible by using just plastic, twine and elastic so that the user can control the finger movements from their wrist. If this isn’t the true definition of a helping hand, then we don’t know what is!
#9 – Pawsthetics
A team of engineering students from the University of Massachusetts have also been working on prosthetics but these are a little different than other prosthetics you might have seen before – Pawsthetics are made especially for animals. This team also use 3D printing to create their prosthetics and their aim is to help the 2.25 million dogs in the USA affected by leg amputations.
#10 – Braces
The final innovation on our list was created by American student Amos Dudley out of need. When Dudley realised that he needed braces to straighten out his teeth, he couldn’t afford the $8,000 cost of the clear braces he needed. So he made his own. He used state-of-the-art technology at his school New Jersey Institute of Technology, to scan and print models of his teeth and created his own custom braces for just $60.
