Ideal Technological System, some practical examples

The previous post got me thinking a bit about the TRIZ concept of an “Ideal Machine” or “Ideal Technological System”. This is a very powerful and deep rooted TRIZ concept, which stated simply can be summed up by the sentence:

“An ideal technological system is a system which does not itself exist as a physical entity but¬†the function that it delivers is still fully performed”

Sounds a bit strange doesn’t it? If the system itself doesn’t exist then how on earth does it deliver any function at all? Well, lets see if we can think of some examples of ideal technological systems, that is, things which delivers¬†functions but which don’t themselves exist.

1. The office printer, scanner, fax¬†and photocopier used to be¬†four discrete devices, each with their own costly consumables and space requirements. Now you can get all the same functions from one device. So you could say that, for example,¬†the fax function is delivered without any system. Here’s a shiny example from Canon to prove¬†it, just look at all the stuff it does!

 

2. As I showed in my post about evolution of technical systems, the system to move aircraft control surfaces¬†has become¬†quite complex due to the need to control and move control surfaces on large and fast aircraft. The¬†active aero-elastic wing (AAW) prototype demonstrates a new way to move control surfaces by using shape memory alloys to flex the entire wing surface. This format eliminates many of the subsystems needed in a conventional wing such as flaps and hinge systems. Incidentally I’ve found some film of the AAW is action which is rather cool.

 

3. OK, I’m going to shift industry area completely now. Here is a final example of ideality. In this case, a recent innovation in dishwashing tablets – Finish Quantum. The key innovation here is that the tablet is encased in a hot water soluble barrier. I know it’s not perfect, I’ve stopped using them myself after a brief flirtation, but you get my point – no wrapper!

 

I hope you can see that such a thing as an “Ideal Technological System” can actually exist in reality and isn’t just a high-flown abstract TRIZ concept. From the TRIZ viewpoint the reason this concept is so important is that all technological systems, even if they are far from ideal right now, tend to evolve towards the “Ideal Technological System” over time, just look at computers, mobile phones and audio media for example (compare MP3 with an LP to get an idea here).¬†¬†
