A certain bridge engineering group is facing the problems of insufficient protection of core technologies and lagging academic achievement transformation in the research and development of key technologies for wind and earthquake resistance of ultra long span cable-stayed bridges. The new steel-concrete composite beam cable-stayed bridge technology developed by the group has increased the bridge span to 1200 meters and improved wind resistance stability by 40%. However, only 5 utility model patents were applied for in the early stage, and the core technologies such as flutter suppression algorithm and shock absorber design are facing the risk of being copied; At the same time, the massive experimental data accumulated by the R&D team has not formed systematic academic achievements, and lacks discourse power in industry technical exchanges.

After our intervention, we formed a cross disciplinary team to conduct technical exploration and identified 15 innovative points in 8 core technology modules, including wind flutter control, structural damping, and health monitoring. In terms of patent layout, a full chain protection strategy of "core technology+construction process+operation and maintenance method" has been formulated, assisting in the completion of 28 patent applications, including 18 invention patents forming a tight protection network, including core patents such as "a flutter suppression method for cable-stayed bridges based on streamlined deflectors" and "magnetic rheological damping device for large-span bridges", covering the entire process from technology research and development to engineering application.

In terms of academic paper conversion, guided the R&D team to extract three research directions with academic value from patented technologies, and wrote six academic papers on topics such as "Vibration Mechanism and Control Method of Cable stayed Bridges" and "Mechanical Characteristics of Composite Beam Structures". By optimizing the presentation of experimental data and highlighting the performance comparison with traditional techniques, four of them were included in the Journal of Chinese Highway Engineering, and two were presented orally at international bridge engineering conferences. Cleverly citing publicly available patent technology principles in the paper, concealing core parameters, not only ensures patent novelty but also enhances academic persuasiveness.

After the implementation of the project, the patent protection coverage rate increased from 25% to 96%, and two cases of infringement were successfully intercepted. Academic papers have been cited 230 times, and the technological influence of enterprises has significantly increased. They have been invited to participate in the formulation of three national bridge design standards. Based on the dual support of patents and papers, this technology has been successfully applied to the construction of three super large cable-stayed bridges, with an additional contract amount of 1.8 billion yuan. It has won the second prize of National Science and Technology Progress Award and become a benchmark for technological innovation in bridge engineering.
