"A system will continue to evolve towards increased Ideality."
In an existing organisation, generally the most sought after goal is to achieve Ideality. The ideal system performs a required function without actually existing. The function is often performed using existing resources.
The Process Involves :
> Useful characteristics to be improved such as Reliability, Action speed, Productivity, Manufacturing accuracy, Dispensing accuracy and so on
> Reducing undesired factors such as Energy consumption, Complexity, Energy & Time wastage, Cost, Noise, Wear, Environmental influence, Harmful human actions
> To improve overall control and management
The process involves the use of the I-TRIZ Universal, General, Auxiliary and Specialised Operators.
These tools work with and integrate other techniques. Focusing on refined innovation knowledge.
I-TRIZ relies on its inherent unified and integrated knowledge base for all types of problems with an exhaustive set of potential solutions.
Pursuing Ideality
The Law of Increasing Ideality: A system will evolve toward increasing degrees of ideality, where ideality is defined as the quotient of the sum of the system's useful effects, Ui, divided by the sum of its harmful effects, Hj.
Ideality = (∑Ui )/(∑Hj )
Useful effects include all the valuable results of the system's functioning. Harmful effects include undesired inputs such as cost, footprint, energy consumed, pollution, danger, etc. The ideal state is one where there are only benefits and no harmful effects.
From a design point of view, engineers must continue to pursue greater benefits and reduce cost of labor, materials, energy, and harmful side effects. Normally, when improving a benefit results in increased harmful effects, a trade-off is made, but the Law of Ideality drives designs to eliminate or solve any trade-offs or design contradictions.
The ideal final result will eventually be a product where the beneficial function exists but the machine itself does not. The evolution of the mechanical spring-driven watch into the electronic quartz crystal watch is an example of moving towards ideality.
