“For travelers, balancing luggage, a snack, personal items, and a drink can be difficult, often resulting in spilling of beverages either while walking around or while seated on, for example, a plane or in a car.”
What one needs, perhaps, is a self-stabilizing drinks-cup holder? And, fortunately, a newly patented solution has become available. Inventor Donald Joseph Berg of Escondido, California, has just been granted a US patent for a ‘Gyroscopic cup holder’. It’s also applicable, they say, for use with bicycles, strollers, carts, boat railings, cars and trucks etc. etc..
The word ‘Gyroscopic’ appears just once in the patent document (i.e. in its title). And perhaps that may be one time too many, as it doesn’t feature a gyroscope of any kind – relying instead on a dual-axis gimbal mechanism.
Also Note :
The 2017 Ig Nobel FLUID DYNAMICS PRIZE was awarded to Rouslan Krechetnikov [USA, RUSSIA, CANADA] and Hans Mayer [USA] for studying the dynamics of liquid-sloshing, to learn what happens when a person walks while carrying a cup of coffee.
