The Inventive Gondola

On a recent trip to Venice I learnt a little about the design of the gondola and was delighted to discover that it displays a number of TRIZ inventive principles.

gondolas

The hull of the gondola is asymmetric (Inventive Principle #4) in order to counteract the asymmetric force of the single oar (the rèmo). Further asymmetry in the hull shape ensures that the gondola floats upright even though the gondolier stands on one side of the vessel – indeed, with nobody aboard a gondola takes on a distinct list to starboard – an example of prior counter-action (Inventive Principle #9).

Similarly the weight of the distinctive metal fèrro at the bow helps to counteract the weight of the gondolier at the stern – an example of both prior counteraction and also equipotentiality (Inventive Principle #12).
I was also intrigued by the complex shape of the gondola’s rowlock (the fórcola) which provides for as many as eight different rowing positions for the oar – a form of universality (Inventive Principle #6).

So, should you ever find yourself taking a romatic gondola ride along the canals of Venice, don’t forget your Inventive Principles!

Never be stumped for resources

The use of resources is an important theme in Triz. It’s useful to develop a habit (perhaps an obsession) of always looking to use existing and/or available resources to solve a problem rather than introducing anything new.
One definition of a resource that I’m fond of is:

“A resource is anything that is not being used to its full potential”

What’s nice about this is that encourages us to look at what’s around us (or in the systems we develop) and consider what additional useful functions could be provided by the resources be find.
Here’s a nice example I spotted a few years ago at the Hunters boat yard at Ludham on the Norfolk broads:

Being there and not being there

One of the moist brutal – and therefore most helpful – physical contradictions we can tackle is one of existence and non-existence. We often find (having vigorously waved the magic wand of ideal outcome) that what we really, really want is for some particular object, thing, component or other thingamabob to be there and not be there. TRIZ will lead us to consider the use of separation principles to solve such a contradiction. In this case a useful trick (which is very much linked to inventive principle #6:  Universality) is to consider a system component that delivers different functions at different times, especially when we have identified a pair of there-and-not-there contradictions. Although, strictly speaking, the component still exists at all times, from a functional perspective it has ‘disappeared’ and been replaced by something functionally different – and ideally useful in its new functional guise.

A folding penknife is an example of this:

Ideally:

  • the handle of the knife should be there (when we are cutting things) and not there (when we are not cutting things
  • the blade cover should be there (when we are not cutting things) and not there (when we are cutting things

The two contradictions are resolved by combing the required functions into a single component that only delivers one of the two functions at a time.

But what about situations in which we cannot separate in time? There is a useful line of attack when we are dealing with systems that interact with people. The human sensing system is complex (especially when we include the processing going on in the brain) and has behaviours and characteristics that can be exploited to resolve physical contradictions. Here is one of my favourite examples:

This stamp is one of set that celebrates a number of British aircraft designers. The Supermarine Spitfire, the most famous creation of its designer Ronald Mitchell,  dominates the image. And yet Mitchell himself is also there – and not there. The stamp itself does not change, but our perception of it can. It’s (almost but not quite) enough to turn me into a stamp collector.

Beyond Brainstorming: Encouraging Team Innovation

I just had an interesting conversation with a client: he asked me how you get a team to move beyond brainstorming. Oxford Creativity have a rule in our innovation sessions, that we always create a “Solution Park” in which we put ideas as they come up, in order to keep people engaged in TRIZ’s systematic approaches.

Brainstorming has its place, and generating solutions is fun, but it has a number of risks.

I’ve thought of an idea!

1) You don’t spend enough time understanding the problem, and you end up solving the “wrong” problem. Probably about 40% of the problems we are brought into solve are not the real problem: they are actually interesting but flawed solutions to a deeper problem. Uncovering and solving that more fundamental problem always generates more robust solutions.

2) You run out of energy. This is why simple tricks or triggers like “imagine how a rose could solve your problem” are often used, but these are random and while they can encourage new ways of thinking, they are not related to your situation. It is a bit like searching for buried treasure and just picking random places to dig. If you spend the time modelling your problem in a TRIZzy way, the solution triggers suggested will suggest the best places to dig, focusing your energy in the right places.

3) You are dependent on the knowledge in the room. Chemists will suggest chemical ideas, biologists biological ideas, mechanical engineers will suggest ideas involving duct tape or hitting it really hard with a hammer (or both). This limits the scope of solutions you can generate.

4) Brainstorming favours certain types of people: not everyone in a team will contribute equally. Some people find it very easy to generate lots of ideas – others don’t. Some people are very comfortable pushing their ideas forward – others aren’t. However if you want to get the most from your team, you need to encourage everyone to participate, and having a big sheet up on the wall and giving everyone post it notes encourages even the quieter people who are often shouted down during brainstorming to participate and share their ideas. And I say this as a noisy, confident person who loves to share her ideas…..(I often feel sorry for the people who have to facilitate me during our facilitation training sessions)…

5) You can be under the tyranny of a facilitator. When you have a facilitator at the front of the room in front of a flipchart, I can tell you  exactly how many people in the room are fully engaged, fully participating and enjoying themselves. One. The facilitator. It can be a collosal waste of everyone else’s time and energy. We always split people into groups whenever we can, but even if you have to have someone at the front of the room with a flipchart, everyone else can still be generating solutions and sharing them.

5) ALL ideas are shared. This is important as the best ideas usually come from combining different ideas together. It also stops the most senior person in the room pushing their idea forward, no matter how terrible it is…

Management often push their own solutions

The joy of teams is that different people come up with different ideas, and we want to capture all of them.

I am passionate about getting teams fully engaged and participating in innovation sessions, and using a solution park is an incredibly simple and very powerful way of encourage team innovation. If you want to start a session with brainstorming, by all means do so, but put all the ideas on the solution park, draw a line underneath them, then move on. Apply systematic tools and I guarantee you will generate many more solutions – and demonstrably move beyond brainstorming.

Learning from my customers: Innovating TRIZ & the 40 Principles

I just had a lovely telephone call with a customer: Kent had attended our public 5 day TRIZ workshop in Oxford in July and I gave him to ring to find out how things were going. He was glad I called as he wanted some help applying the 9 boxes, as he is going to be running some problem solving sessions soon using TRIZ, but found it hard to work out how to apply the 9 boxes sometimes. We talked through the different ways you can apply it, but I mentioned a side benefit of the tool in problem solving sessions as a facilitator.

I find starting a session with a 9 box context map really useful for understanding the problem – you map out the history of the problem, looking at what happened in the past and what will happen in the future if you do nothing. Formally mapping out the context and details of the problem’s history helps me as a facilitator understand where the big issues really lie, and ensures we are looking at the problem at the right level. 

However he then mentioned that he had done some maths on the matrix and the 40 principles! He had done some statistical analysis and found that Inventive Principle no.35, Parameter Change, is the most often used principle. This I knew, but what I didn’t know is the next most commonly used principle. He found the order was this:

35 – Parameter Change

Image

10 – Prior Action

1 – Segmentation

28 – Replace Mechanical System

I thought this was really interesting and I will keep an eye out in future sessions about whether these principles do tend to be suggested more often than others. 

What has been your experience?

Formula 1 technology monitors children in hospital

An interesting article in the BBC this morning highlighted how technology is being adapted to different fields.

Telemetric data from cars is being continuously recorded and fed back to the F1 team, allowing them to monitor the levels of tyre temperature, engine output, suspension, braking and any other part of the car that needs to be watched. This information then allows the team to make adjustments to the car before races and refine the performance of the car over the season.

The technology that supports this has now been adapted to the field of health care, with Birmingham Children’s Hospital using it to monitor children in intensive care. Hospitals can keep an eye on a number of results, including blood pressure, oxygen levels, temperature and heart rate, and respond faster if a change in these is noted. The aim is that this information will be sent wirelessly, reducing the cost and speeding up the process.

TRIZ encourages us to look at the wider world for solutions to our problems. One of the first questions we ask before any problem solving session is “Has someone solved this problem before?”

By reducing the problem to its most important elements we can use the prism of TRIZ to identify possible solutions to our problem.

This new collaboration has got off to a strong start and hopefully we will be seeing this in hospitals more and more into the future. What other areas could telemetrics be expanded to? Let us know your thoughts in the comments.

Inventive Principles and the Olympic Cauldron

It was good to see a number of Inventive Principles at work in the Olympic cauldron during the opening ceremony on Friday night.

Image

 Segmentation, Dynamics and Merging (among others) enabled the design to solve a number of physical contradictions:

  • There should be one flame and many flames (204 in all)
  • The flames should be separated (so that each participating country is individually represented) and yet together (not separated) because all countries are united through a common Olympic spirit.
  • The flames should be low (so that they can be lit from ground level) and high (so that the whole caboodle is more visible and impressive).

In many respects there a cauldron – and not a cauldron.
