The most popular inventions are innovative designs to create fresh water from polluted, brackish, or waste water. Solutions that do not depend on any fuel except sunlight, and yet can maximize the output necessary to support a human's need - are by far the toughest problems and most valuable answers. Lack of clean water kills more people than any other affliction in many poor countries.
Competitions are also held in professional design circles for mobile housing units for medical treatment centers. These all-in-one clinics are efficient and yet can deal with the majority of issues for a local area (mostly infection-based).
Since many populations in poor countries are illiterate, education about preventative lifestyles regarding STDs, food/water preparation, and other health issues is very difficult. Superstitions and incorrect beliefs could many attempts to introduce changes for healthier living.
It's fun and usually free to participate in such competitions, try it out and good luck!

Many people use the internet and have cell phones... if you consider them new inventions.
