Objective Laws Of System Evolution Systems Evolve in Predictable Ways

Propeller Pushes Vessel Water Lifts / Positions Water Propels Materials / People Transports Systems Never Remain Static Sails Pushes Vessel Water Lifts / Positions Wind Pushes Materials / People Transports

Super System Sub System PastPresentFuture Systems Change at all levels

If two systems have the same function, but use different effects (physical phenomena) to deliver the main function we will call them different systems

Same Propulsion System Same Function and Same Effect (Oars) Different Propulsion Systems Same Function but Different Effects (Steam Powered and Wind Powered)

What Stages Occur Between Effects? Lifts Payload Light gas Lifts Payload Wing Lifts Payload Propellant

Law of Stages How systems grow up

Stage 1: Determining the Parts and Where They Go

Fuel Tanks become supporting structure Stage 2: Removing the Bad Marks

Boosters can be added or removed depending upon payload Stage 3: Dynamizing = Make Adjustable

pressure Stage 4: Introducing Feedback

Stage 5: Transition To New Effect The Effect is Still Present but... Macro to Micro (Make use of Bulk Properties) Ionic Drive Engine uses bulk properties of Plasma + = Combine with Super-system

Time For a New Effect? â Is automatic feedback used to perform the main function? press ure â Has the system reached the point of diminishing return? â Must multiple conflicts be resolved for improvement? â Has the system become very specialized?

infancy Rapid growthMaturity Stagnation Technical parameter related to main function Number of inventions Profit Level of invention Level of invention 1. No resolution of contradiction 2. Resolves contradiction with small change 3. Resolves contradiction with a major change. Uses technology from same field 4. Resolves contradiction. Complete change in Effect. Usually a technology from another field. 5. Fundamental Effect. Has ability to change the super-system to which it belongs. New Effect Towards End of Maturity

Law of Increasing Ideality Ideality = Index of Useful Functions Index of Harmful Functions Less Harmful Functions (Includes $ Time Weight and Harmful Interactions) More functions done better

Ideality Exercise Based upon the laws of ideality, what should happen to this lawn mower?

Law of Shortening Energy Paths What should happen to this automobile transmission? ã Transmissions paths are shortened and eventually eliminated ã Energy transformations are reduced and finally eliminated. ã Muscle and control signals use the same field.

Law of Non-Uniform System Development Engine Bleed Valve Engine efficiencies improve as temperatures increase. What effect will this have on an attached valve? â System parts are improved in “fits and spurts” â When one part is improved, other parts may be harmed. â System improvement is slowed by increasing conflicts. â When one part improves, other parts may appear worse by comparison. â System Takes on Subsystem improvements and Effects

Law of Transition from Macro to micro â Functions performed at the macro-level are eventually performed at the micro level where the bulk properties are controlled by a field.
