Recently, the 8th China TRIZ Cup College Student Innovation Competition, jointly sponsored by the China Association for Science and Technology and the Ministry of Science and Technology, came to an end. 23 works from NEFU stood out from the more than 1,300 works from 157 colleges and universities, winning 1 special prize, 2 first prizes, 6 second prizes, and 13 third prizes. NEFU also won the Outstanding Organization Award.
Due to the impact of Covid-19, the competition was launched online, and the final was conducted through online video conference. The works from NEFU won many prizes in the final. “Compound straw micro-powder machine” won the special prize of the innovative design group, “a leaf removal, peeling and scraping straw stalk separation device” won the first prize of the innovation design group, and “a UV-curable castor oil-based waterborne polyurethane dispersion and its preparation method and application” won the first prize of the process improvement group. Six works such as “snow and ice removal device for sidewalks” won the second prize, and 13 works such as “vitrified microbead modified polyurethane foam material based on TRIZ theory” won the third prize. In addition, “the application of TRIZ in the safety design of biomass flat mold machine” won the excellent teaching achievement award for innovative methods. Additionally, Fu Min won the honorary title of “Outstanding Instructor”, and Xu Xiaojia won the honorary title of “Outstanding Liaison Officer”.
Under the theme of “For Innovation and Entrepreneurship, Method Goes First”, the China TRIZ Cup College Student Innovation Competition has received more than 1,300 entries from 157 colleges and universities from 24 provinces, municipalities and autonomous regions since its official launch in August of this year. The competition is close to actual life, so that more scientific and technological achievements can be transformed into real social productivity.
Project Introduction
compound straw micro-powder machine
The comprehensive development and utilization of straw has become a hotspot of international concern. After being powdered, straw can replace wood flour as a filler to extract nutrients such as lignin, thereby achieving high-quality utilization of straw resources, but currently there is no straw micro-powder machine on the market. In response to the existing problems of large particle size and low production efficiency of straw crushing, 15 TRIZ tools such as function-oriented search, scientific effect library, S-curve and technical system evolutionary rule, functional analysis and tailoring, nine-screen diagram and resource analysis, causal chain analysis, STC operator, goldfish method, IFR, contradiction analysis, object field model, etc. were adopted, and 39 plans were proposed for the 9 parts including crushing method and crushing chamber, and 2 implementation plans for compound straw micro-powder machine were obtained.
