June 2009's TRIZ Journal

| On 01, Jun 2009

Welcome to the June 2009 issue of The TRIZ Journal. This month’s articles include:


Advanced Electrical Discharge Machining and TRIZ


Electrical discharge machining (EDM) is a non-traditional process based on thermoelectric energy between a work piece and an electrode. A pulse discharge occurs in a small gap between a work piece and an electrode, and removes the unwanted material from the parent metal through melting and vaporization. The electrode and the work piece must have an electrical conductivity in order to generate a spark. Dielectric fluid acts as a spark conductor, concentrating the energy to a narrow region. There are various types of products that can be produced and finished using EDM such as moulds, dies, aerodynamic parts, automotive and surgical components. This research reveals how vibration can be incorporated into EDM through modeling an advanced design called the ultrasonic electrical discharge machine (UEDM) using the Theory of Inventive Problem Solving (TRIZ).

TRIZ-based Practice Book in Education


The demand for research work from students, ages 6 to 10 years old, is growing due to the changing requirements of school graduates. Depending on a student’s age the research activity assigned is directed toward the reception of subjective novelty or the development of working skills with information sources.

Using TRIZ Tools for Airport Runway Optimization


Theory of Inventive Thinking (TRIZ) tools are used in the conceptual design and layout of novel runway models (ascending and descending) for the effective use of short length airport runways. When handling bigger aircrafts at smaller airports it is necessary to consider the economic effects and benefits of the larger airliners, and assisting more air travelers of the region. The proposal of ascending and descending runways enables the operation of wide body aircrafts such as the Boeing 747 and the Airbus A380-800 by using the third dimension of a runway with a gradual slope of 2.5 degrees in addition to a rapid exit runway diversion of 18 to 22.5 degrees from the main runway orientation.
