Against the backdrop of accelerating globalization and industrialization, traditional handicrafts embedded in specific socio-cultural contexts are facing critical challenges, including a decline in inheritors, shrinking market demand, and increasing disconnection from modern lifestyles. Promoting their integration into contemporary society while preserving cultural authenticity and ensuring their sustainable transmission and development has become a key issue in Intangible Cultural Heritage (ICH) revitalization. This study takes woodcarving in Qianjiang, Hubei Province, China, as a case study to explore transformation pathways for traditional handicrafts in the context of modern consumption. Questionnaire surveys were conducted to examine tourists’ preferences for cultural and creative products, and a user demand framework was constructed based on the three-level emotional model. The Analytic Hierarchy Process (AHP) and Decision-Making Trial and Evaluation Laboratory (DEMATEL) methods were employed to identify key influencing factors and their interrelationships. The results reveal significant differences among target groups in terms of cultural identity, emotional experience, and purchase intention. Based on these findings, a systematic framework of “demand identification–design concept–implementation strategy” is proposed to guide the sustainable design and development of traditional handicraft products. Furthermore, this study explores the integration of traditional craftsmanship with digital production to balance production efficiency and cultural expression. This research contributes to the theoretical development of ICH revitalization and provides practical insights for the cultivation of sustainable cultural and creative industries.

Distributed photovoltaics (DPV) is rapidly expanding under the “Dual Carbon” strategy, yet suffers from a systemic imbalance of prioritizing construction over service provision. Existing research focuses predominantly on techno-economic analyses, neglecting holistic service lifecycle examination, systematic urban-rural comparison, and actionable design tools. This study employs qualitative methods, including literature review, case analysis, service blueprinting, and stakeholder analysis, to examine DPV full-lifecycle services across rural household and urban commercial and industrial contexts. Findings reveal multi-stage service breakpoints, including early-stage information asymmetry, mid-stage unclear responsibility allocation, and late-stage recycling absence alongside significant urban-rural variations. To address these gaps, the study proposes a sustainable service design strategy balancing efficiency, equity, and resilience, comprising visualized rights-responsibility checklists, tiered revenue distribution schemes, and standardized full-lifecycle service blueprints. This work contributes a lifecycle service architecture, a systematic urban-rural comparative perspective, and practical governance tools for DPV sustainability. This work makes the key contribution that includes a full lifecycle service architecture as the core framework, systematic urban-rural comparison as the analytical perspective, and actionable governance and service tools as the practical outputs.
