Extra IKEA parts. A service design.

I'm probably not the typical IKEA customer but for us frequent IKEA shoppers, at some point, we have bought so many IKEA furniture and hate throwing away good useful extra parts/tools that comes with the simple 1-2-3 DIY boxes, it seems very wasteful to keep getting parts I don't need but have no where to dispose of them fruitfully.

So. How about this?
What if IKEA had a fun station for the frequent buyers with a ton of spare parts of some parts and not others, where there's a dispenser that automatically dispensed the parts we'll need to build the furniture we just bought, bag up the ones we are lacking and put the rest back in the 'Extra Parts Bin'.

And like a coin organizer, the extra parts bin can easily organize all the various parts to the different components and feed back to the parts vending machine.

IKEA today already currently have stations in the back door to get some extra parts.

The proposed assembly line system can also feed to this back door supply and make it fun and gadgety to get extra parts :)

I love these self service stands; I feel more part of the shopping and building experience.
It's not for everyone, especially if you want a quickie at crowded IKEA. But perhaps Mr. Ford might approve of this self service assembly line... :)
I love optimization problems. In another universe, I might've studied Operations Research Industrial Engineer ...
