On May 7, the paper structure model design competition of the School of Marine Science and Engineering was held in the 202 laboratory of the Haike Building. The 11 participating teams used A4 paper and glue as materials to design and manufacture load-bearing structures, and finally won the first prize with a load-bearing ratio of 191.6kg/99.1g, showing the engineering ingenuity of light weight and high strength.
Two weeks before the competition, the teams began to prepare intensively, and through repeated tests of the paper tube diameter, folding angle and mechanical distribution, they explored the optimal structural solution. Triangular supports, hollow cylinders, hexagonal prisms and other designs have both stability and aesthetics, and creative models such as core wrapping and nesting show their style on the field. The competition is judged by the ratio of the weight of the model to its own weight, and the contestants need to balance science and artistry under limited materials.
The weight-bearing test brought the competition to a climax. The team members stacked the weights on the wooden board on top of the model layer by layer, from 2.55kg large weights to 0.1kg small weights, and each time they were placed, the precision of the model's structure was tested. With the roar of the weight falling to the ground and the exclamation of the team, the results of the competition were settled: Three Fools Messing Around A4 Paper and 23 Material 2 won the second prize, three teams including Not Quite Team won the third prize, and another five teams won the Excellence Award.
This competition breaks the traditional manual creation mode and integrates engineering design thinking. From drawing design, mechanical analysis to disassembled assembly, students transform professional knowledge such as materials science and structural mechanics into real-world results through the practical process of optimization-failure-reoptimization. The person in charge of the event said that although the paper structure is small, it carries the exploration of systematic innovation, and provides a vivid classroom for cultivating the ingenuity and collaboration ability of future marine engineers.
A piece of tissue paper, a thousand powers. When the lightweight model lifted hundreds of kilograms, the students used wisdom and sweat to interpret the spirit of the competition of a thousand pieces of paper, highlighting ingenuity, and also wrote creative footnotes for professional learning.
