Addressing the critical demand for high-level research capabilities, this study employs a mixed-methods approach to investigate sustainable digital literacy cultivation pathways through a longitudinal case study (2020–2023) of the Non-linear Control Systems course. A pedagogical framework was developed, integrating three core mechanisms: goal-oriented instructional design aligned with DIGCOMP 2.2 standards and a quadruple mentorship system encompassing digital literacy, academic, project, and enterprise mentors. Implementation outcomes demonstrated statistically significant advancements, including a 55%−68% improvement in technical problem-solving competencies (p < 0.01). Student satisfaction rates surged from 78% to 95.45%, with medium-tier academic performances eliminated post-intervention. These findings substantiate the framework's efficacy in bridging theoretical-practical gaps through competency-based assessment protocols and adaptive mentorship architectures. The study contributes actionable strategies for engineering education reform, including scalable curriculum-digitization models and evidence-based industry-education integration frameworks, ultimately cultivating professionals equipped with sustainable digital competencies for intelligent manufacturing ecosystems.
