Architectural Constraints in Silk Processing Technologies: Implications for Technology Transfer and Rural Value Capture

Silk-processing technologies play a critical role in supporting rural livelihoods and bio-based production systems across the Global South. However, many prevailing technological trajectories remain poorly aligned with the operational realities of small-scale and resource-constrained production systems. This study examines 252 granted patents related to silk-processing technologies through a qualitative, system-level analysis of four key architectural dependencies associated with input standardization, operational continuity, downstream infrastructural integration, and operator-technology coupling. The findings indicate that patented technologies frequently assume standardized inputs, coordinated processing environments, complementary infrastructure, and sustained technical supervision. Together, these interdependent characteristics form architectural configurations that may create technology-fit constraints and participation thresholds for small-scale rural producers, potentially limiting opportunities for technology transfer and participation in higher-value segments of the silk value chain. The results further suggest that the transferability of the patented technologies depends not only on their technical performance but also on the extent to which their underlying architectural assumptions align with local production contexts. By emphasizing the importance of context-adapted technological design, this study contributes to ongoing discussions on sustainable production systems and rural innovation, highlighting pathways to improve technology fit and reduce participation barriers in small-scale production systems.
