Rules for the Invention Convention

Here are the basic rules for taking part in the CT Regional and State Invention Conventions. For more information and details, inventors should read the FAQ and the APP info sheets. 


1. An invention must be the product of a single inventor.  Pair or group inventions are not allowed.

2. Prototype Size - The size of the invention prototype must not exceed 2 feet wide x 2 feet deep (height is less of an issue). The inventions are allowed a space of 2 feet by 2 feet on the tabletop in front of the Display Board. If the invention is too tall to fit safely on the table, you are allowed to put it on the floor in front of the Display Board. However, if the invention is larger than 2 x 2 feet, it will not be allowed in the event venue to be displayed at the event. Instead, you can build a smaller prototype that fits in the space allowed, or take a few pictures or short video demonstrating how the prototype works. Please see the FAQ for more information.

3. An invention must meet the following definition:

An invention must have utility; it must solve a real problem.  It is something that no one has ever made before.  It cannot be purchased in a store or found in a book.  An invention may be a non-obvious improvement to an existing object that yields new utility.

4.  The cost of the invention prototype should not exceed $50. Inventors are encouraged to use recycled materials.

5.  Display Board

    • The invention must be accompanied by a self-standing display board (requiring no more than 24 inches of table space) that includes the following information:

      • The title of the invention

      • A description of the problem the invention solves

      • A description of how the invention works

      • The inventor’s name, grade, and school

5.  The inventor must submit an Invention Log that:
