Inventor’s Log

Maintaining a logbook is an important part of the inventing process. The logbook is a written record of the process of creating the invention. This should be written as the inventing is going on and not compiled after the process is complete. The logbook does NOT have to be in any particular style or format. And it does NOT have to be perfectly written, drawn and spelled. Sloppiness and errors should be avoided, but they are not fatal flaws.


The logbook can contain more information and sections, but as a minimum it should address each of the Stages of Invention.

  • Identifying the Problem
  • Understanding the Goal
  • Identifying a Solution
  • Designing a Solution
  • Building a Device
  • Testing & Evaluating the Device
  • Communicating the Results
