It’s frequently the case that a person has an insufficient number of hands to perform a particular task. Specifically, a person carrying two objects (Figure 1) might temporarily need an extra hand to operate a door handle / press a button / etc.
As shown above, solutions to this problem are inelegant at best.
Technology to the rescue! Although most people have at most a single arm attached to each shoulder, there’s really no reason these shoulders couldn’t accommodate another arm (Figure 2).
These bonus arms could be made to be extremely stable, like a camera stabilizer (frequently referred to by the brand name “Steadicam”). It’s possible that the “bonus” arm would actually be less prone to spilling a coffee than a regular human arm!
It would be easy to wear a set of extra arms as a sort of “backpack,” so attaching them securely is clearly no issue at all.
Although people would probably take some time to warm up to this idea fashion-wise, it’s almost inevitable that this will be part of the standard business attire of the future.
PROS: Reduces the chance of deadly career-ending coffee spills.
