To address the issue of bridge cables being covered by ice, the work aims to study and design a bridge cable deicing device through an improved coupling double-drilling program. Through the coupling improvement of the double-drilling program, various design models were integrated into a comprehensive design program to carry out the function requirement exploration, requirement weight quantification, technical requirement transformation, core function contradiction group construction and solution output of bridge cable deicing device successively, thus achieving the coupling effect of "the whole greater than the sum of parts". Ultimately, the complex design requirements for the deicing device were resolved by the coupled improved double-drilling program, resulting in a design proposal for a bridge cable deicing device. Theoretically, the coupled improved double-drilling program demonstrates significant advantages and advanced capabilities for complex device design development. Practically, the bridge cable deicing device meets the specific deicing needs and aligns with the current trend towards unmanned hazardous operations, ensuring a certain level of scientific validity and rationality.
