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
