I. Invention, innovation and design

  1. How generic technologies (automobile, electric lighting, electronic computing, etc.) develop

  • Concept Development Stage - The invention exists only as an idea in the mind of progressives and dreamers.

  • Demonstration of Basic Concept - Usually comes from scientific research. Prior to this point the invention or technology can only exist as an idea

  • The Trailblazing Stage - Characterized by individual inventors or R&D groups demonstrating inventions which do not become innovations.

  • The Commercial Development Stage - Characterized by highly expensive and/or poorly performing commercial products

  • The Commercialization Stage - Characterized by mass product and applied research aimed at lowering costs and improving performance. The performance/cost ratio vs. time curve takes on a sigmoidal shape.

  • Maturity - The performance/cost ratio stagnates. Sometimes the product is replaced.

  1. Invention/Innovation case studies

  • bicycle

  • automobile

  • electric lighting

  • computers

  • wireless communication

  1. Idea Generation

  • Market Pull: Problems in search of a solution
  • Technology Push: Solutions in search of a problem
  • Demonstration of New Scientific Findings: Example - glowing platinum wire led to the light bulb.
  1. Take an Invention from Concept to Prototype - the Lemelson-MIT InvenTeam method

  • conduct literature searches on  ideas
  • conduct patent searches
  • find clients and customers willing to help develop the idea
  • write a Lemelson-MIT type invention statement
  • run simulations of basic concepts using programs such as Interactive Physics
  • develop time line plans (Gantt charts) using Excel
  • develop and track budgets using Excel
  • make detailed and 3D drawings using CAD
  • build prototypes
  • assemble a final report which will sell the idea to potential investors.
  1. State why inventions succeed or fail to become innovations.

  • Marketability - Can it be sold

  • Financial Support - Are investors available?

  • Marketing - Can customers be identified and served?

  • Need - Does it solve a problem or address a human need?

  • Cost - Can it be manufactured for a low enough cost to be sold?

  1. Protecting Inventions and Other Intellectual Properties.

  2. Invention, innovation and the environment
