How a real life problem is solved - to buy or not to buy a new washing machine

thumb how a real life problem is solved buy or repair

This was a simple act of domain mapping using abstraction. The nature of fault was generalized to body repair, detaching it from the domain of washing machines. We were now on the lookout for a reliable mechanic in the more general higher layer domain of metal body repair...

This problem in contrast to the earlier one looked difficult. The challenge was on - would we be able to achieve its elegant solution? Not always we know about the end in the beginning of our journey, but finally concept based strategic approach provided the initial breakthrough and then led us to the elegant solution in a few more steps...

How to solve a simple looking problem with a twist, domain mapping


In a problem that looks simple but somehow wrong and violates the commonly known concepts, power of abstraction may often overcome the apparently unknown and uncertain state and helps to reach the elegant solutions. On the way to the solution, usually a higher level rich concept is created the precise form of which was hidden just around the corner...

Principle of disproportion saved us millions this time

thumb_principle of disproportion

All things in nature are in proportions that we accept and have become used to. Mimicking nature we build our things that also follow rough proportional relationships that we are not always explicitly aware. But when such a proportional relationship is violated outright we might feel something is wrong, if we have the principle of disproportion imbued in us.
