Be another Edison - give light to the world! Put your hands and minds to creative use and invent something that would make life simpler and brighter for all mankind. This is your chance to put your creativity to the test. This category allows you to stretch the boundaries of your imagination.

The final requirements for this category are:
1. A working prototype of the Invention
2. Evidence of testing / trials carried out to improve the prototype
3. An invention log
4. Project-Details Submission (in line with Tan Kah Kee Young Inventors' Award)


1. The Invention:
The emphasis is on originality and creativity. Both these concepts may be interpreted in a variety of ways, e.g. if a piece of wood is your base material, how would you exploit its shape, size, texture, flexibility, etc.

You are encouraged to modify and recycle materials. Parts may be purchased, but projects would be severely penalized if many of the major parts of the prototype were obtained commercially. You need to demonstrate the invention with a working prototype. Research or surveys and experimentation with the prototype needs to be conducted to convince the teacher evaluators that it is feasible and would benefit others.

All projects should be of a size and scale that you can handle as students, within the limited time-frame given. Do not be too ambitious – you might find yourself frustrated with an unfinished project when it is time to be evaluated.

There is no restriction on the amount of outside help obtained, but these sources have to be acknowledged. Sponsorship or funds obtained should also be clearly indicated. Naturally, projects which are the brainwave of students and done entirely by students would score better in the teacher evaluators’ assessment.

In the Proposal Round, you are only required to present the objective and a reasonable background research of a project of substantial potential with a powerpoint presentation.

In the Mid-Term Evaluation Round, you will need to showcase the details of your project, which would have to be more than 80% completed and the prototype of your invention has to be constructed by this stage of evaluation. A powerpoint presentation is expected for this round of evaluation. There should be evidences of testing or trials carried out to improve the prototype.

In the Final Evaluation Round, the whole project should be completed. You will be evaluated on your oral presentation with appropriate visual aid.

High quality invention projects will be identified after the final evaluation for external competitions, such as Tan Kah Kee Young Inventor's Award, Science Fair, etc.

2. An Invention Log:
An invention log has to capture your inventive process. You should start using one the moment you think of an idea for an invention.

Keeping an invention log is a very important part of the invention process. Your log book can help you prove that you had the idea for this invention first.

Inventors sometimes have to prove they were "first to invent" in order to receive a patent.

Your log book can also help you keep track of all your ideas, and it will help you organize all of the steps required to complete the invention process. The log book will help you capture your group’s reflection throughout the invention process as well.

You will need to present your invention log (online or hard-copy) to the teacher evaluators during all stages of evaluation.
