Study Notes

Function-Oriented Search (FoS)

FoS is a structured search method for problem-solving, focusing on adapting existing solutions rather than inventing new ones
TRIZ encourages borrowing concepts from other industries or nature to address biomedical problems
FoS involves adapting solutions from existing technologies or natural processes

FoS Steps

Define the core function
Generalize this function
Find relevant technologies (e.g. from leading industries/nature)
Come up with a new concept
Apply this new concept in the current scenario, ensuring its suitability for the problem
Invent a product using this new concept

Case Study: Disinfecting Contact Lenses

Contact lenses require sterilization for safe use
Traditional chemical sterilization methods have drawbacks
The objective is to develop a new technology for disinfecting contact lenses

Case Study: Sterilizing Contact Lenses

The process involves a cleansing agent sterilizing contact lenses
A general function model includes removing germs, cleaning, sterilizing, and sanitizing

Contact Lens Sterilization (Generalized Function)

remove harmful substances
clean the lens
sterilize the lens
sanitize the lens

MATCHEM Fields

Mechanical, Acoustic, Thermal, Chemical, Electrical, Magnetic, Intermolecular, Biological
These fields describe possible interactions and substances relevant to contact lenses during sterilization

PG Case Study – Teeth Whitening System

A polymer tray filled with whitening gel is used
The gel causes gum damage, needing one-night application per week
The goal is to find a way to whiten teeth without damaging gums

Function Model (Teeth Whitening)

The tray (irritates gums)
The gel (damages gums)
Removing plaque
Diluting the gel with saliva
