Design Question

Lots of us have been hurt while chopping onions or doing something else with a knife.
That pops a question asked to me some years earlier :
"What would you change in the design of the Knife to make it safer?"

Oh Anonymous Fella,

Some observations on your solution :

(a) The risk associated of cutting yourself has been replaced by the risk of electrocuting himself (minimal but not zero!)

(b) Other than the blades your redesign requires the "electrical technology" whereas knife requires using only one technology : light.(so that you can see the oject)

(c) The complexity has been increased exponentially

Now I am not saying you havent solved it, but I am pointing the cost versus benefit ratio seems unjustifiable for most cases and also the fact that the redesign didnt spare the original design.

BTW This question was asked in a technical interview :-)

Damn it, If you take the edge of the knife, its no more a knife. All you can do is guard against its attacks. Perforated metal glove would do or go on a liquid diet or transfer the risk by employing a servent.

Hehe...i thought n pondered n couldn't find a solution..then I read the comments and aw it's a technical question! *light shines* Now how could "I" get it then!;-) LOL!

Fascinating though...

PS Am highly amused by the exchange between Anonymous and you!

You are right.Thats what I referred to as "not sparing the original design".A good designer always prefers miminalism of changes to leverage a maximum functionality.
Usual Anon: You of the all the people would know this.

[Geetanjali] *light shines* ..You are right.My solution is incorporating intelligent sensors in the blade that sense to cut anything except human skin.
