A Large Variety of Writing Instruments: Students had no ideas on - PowerPoint PPT Presentation

TRIZ Future Conference 2010 Report of the Seminar Class for 2nd year students of Faculty of Informatics Held by The Europen TRIZ Association (ETRIA) April to July, 2010 (1st semester): 90 minutes × 14 = 21 hrs. 10 students. A Large Variety of Writing Instruments: Students had no ideas on technology development nor TRIZ, Studying the Evolution of Technologies when they selected (or were assigned to) and started this Class. in Familiar Items ==> A Class to learn important TRIZ/Technology concepts without using any TRIZ terms/tools November 3 - 5, 2010 Initial Wondering Situations before the Class University of Belgamo, Italy For what purpose this class handles Toru Nakagawa (Osaka Gakuin Univ., Japan) , things like 'Writing instruments'? Kurumi Nakatani (Osaka Gakuin Univ., 2nd Yr. Student) , Do they have any relationship with PCs or IT? (1) List up different kinds of Writing Instruments, (2) Understand the Basic Mechanisms of as much as you can think of ! Principal Writing Instruments ! - Show your own favorite writing instruments of everyday use, Explain the mechanism/principle of writing/drawing with and explain their good points! each Writing Instrument ! - With the keyword of 'writing instruments', Pencil: The graphite crystal (of the lead) leaves its fragments on the paper. list up as many examples as you can think of ! Ballpoint pen: The small metal ball rotates and transfers the ink (liquid) onto - Describe each item on a Post-It-Note, one after another ! the paper. - Instead of a commercial product name, Pen: The slit of the pen tip transfers the ink (liquid) through little by little. Felt pen: The porous part of the pen allows the ink (liquid) to go out little by little use more general name of the product ! onto the paper. - Put every item card on a big sheet of paper, and try to classify them ! Classify the Writing Instruments with the mechanisms ! - Homework: Visit stationery stores, convenience stores, home-centers, stores of drawing materials, etc., and Pencil and chalk belong to a same group. survey various kinds of writing instruments ! Crayon is similar, but slightly different. Mechanical pencil is just a version of pencil made convenient. ... Watch the products closely, take photos, and take notes of them ! Also study in libraries, on the Internet, in catalogues, etc.!
