What is a Technical System?

Anything that performs a function is a Technical System

Model of a Function
A function is an intended direct
(physical) action of the tool on the
object Tool Object
function
Formulation of Functions Correct (If not, Correct it)

Fan cools the Body
Lens magnifies the Object
Hot air dries hair
Incandescent bulb illuminates the room
Air Conditioner improves our comfort
Lightning Rod attracts lightning
Microwave Oven cooks Food

Exercise 5 minutes (group of 4/5)

You are a patent engineer – you received an Invention Disclosure as described
below – Please write down an abstract (Maximum 30 words)

A motorbike with wireless connection to a mobile phone. The mobile phone
controls the bike. When you buy the bike, mobile phone is given free of cost



You are a patent engineer – you received an Invention Disclosure as described
below – Please write down an abstract (Maximum 30 words)



Exchange the abstract written by your group with the group next to you.




You are Now a novelty evaluator – you received the abstract of the
ID with you – Please make relevant keywords and logical (and,
or, not) queries you will use to search for the prior art in the
US PTO!

FSA- Function Analysis

Adequate Useful Action

Absent Useful Action

Inadequate Useful Action

× Harmful Action


1. Law of Increasing Degree of Ideality -
Increasing Ratio -> Benefits/Harm (cost)

Law of Increasing Degree of Ideality (Cardinal Law) Fully Functional System
No Resources No Harm

How close to Ideality is the How can you make it closer to
current Invention? ideality?


2. Law of Non-uniform evolution of subsystems
-> Leads to System Conflicts

Law of Non-uniform evolution of sub-systems More Complex System
means more non-
uniformity

Which sub-systems are closer to What are the conflicts if any sub-
ideality? systems function is intensified?


3. Law of Transition to a higher Level system
-> from simple to more complex

Law of Transition to a Higher level system Multi-functional system

What are the Useful functions What more functions can be
provided? combined?


4. Law of Increasing dynamism (flexibility)
-> More adaptable to change

Law of Increasing Flexibility Adaptable System

What parts can be made more Based on different environments,
flexible? what changes can be done to make
system functional?


5. Law of Transition to micro-level
-> Increasing fragmentation

Law of Transition to Micro Level Micro level structures

What parts of the system can be What micro materials are
replaced by micro structures? available?


6. Law of Completeness
-> Gradual Elimination of
Human Component

Law of Completeness No Human Involvement

What parts of the system has How to eliminate human
human involvement? components?


7. Law of Shortening of Energy Flow Path
-> Reduction in Energy/Info
transformation stages

Law of shortening of Energy Flow Path Energy Flow in the
system is close to zero

What parts of the system have Can one shorten energy flow?
energy flow?


8. Law of Increasing controllability
-> Evolution of controlled
interactions of system elements

Law of increasing controllability Completely controlled
field

How can one control the field – for
What parts of the system non- example changing gravity to
controllable fields? electric field?


9. Law of Harmonization of
rhythms -> Synchronization of
natural frequencies of elements

Law of harmonization of rhythms Perfect resonance of
parts

What parts of the system have How to make these activities in
various time based activities? perfect harmony?


Applications of Patent Analysis

Patents as a trigger for Brainstorming
Technological Alternatives or Design Around a Patent
White Space Identification
Opportunity Finding


Patent as a Trigger for Brainstorming

Map the conflicts identified for the whiteboard marker patent to the Contradiction
Matrix and identify the relevant Inventive Principles. Generate ideas for each of those
principles to solve the problems or generally think about a new whiteboard marker.

Trimming and Design Around a Patent

Designing around the patent means changing the
Function and Structure Analysis Picture in some way so that it is different from the one
in the original patent, but that delivers the
Same (or better) useful functions to the user. Look at the Function and Structure
Analysis picture for the whiteboard marker patent. How can it be altered – can some
element be eliminated from the system completely?
