China is the main technology research and development country in the world’s bamboo industry, as well as the main producer and exporter of bamboo products. It ranks at the international leading level in terms of bamboo forest area, stock volume, bamboo product output and scientific research level. However, through literature review, it is found that the development of bamboo products in the modern social environment still faces many challenges. The author searched the keyword “bamboo product design” through CNKI and SCOPUS database systems, and initially retrieved 562 literatures. According to the screening criteria “Bamboo Product Design Status and Strategies”, and excluding redundant and repetitive studies, 76 papers were finally screened and identified. The author uses the A-type graphical tool of the KJ method to combine, classify and analyze the keywords in the “problem” literature, and use the relationship between these materials to organically combine and summarize these facts. It is found that there is a gap in capability between bamboo product designers and craftsmen. What is the gap between them? How to narrow the gap between them and improve their design capability? This is the research question of this study. To a certain extent, it is one of the key factors for the insufficient design innovation of bamboo products and the inability to meet consumer demands. Therefore, this study constructs a strategic framework of five capability dimensions by reviewing the literature on design capability management, combining product design standards and design capability demand theory, and incorporating the unique relevant factors of bamboo product design. The framework aims to improve the knowledge system and professional capability of craftsmen and designers to enhance the diversification and innovation of bamboo products, help the bamboo industry to clarify the market positioning of products, and meet people’s needs for bamboo products in modern life.

There have been reported cases of wellbore instability near-wellbore area due to failures associated with drilling operations, the magnitude and extension of the failure area is imprecisely evaluated by copious researchers due to some of the limitations posed by the numerical simulations used. Therefore, this paper estimates a failure zone area near-wellbore based on the conducted coupled Thermal-Hydro Mechanical (THM) analysis integrated into UDEC, wellbore enlargement, and Failure area analysis. A two-dimensional horizontal plane stress model of 2 × 2 m is created using rock properties from a vertical well, and a wellbore radius of 0.11 m is drilled under confined stress using the in-situ stresses. The Voronoi tessellation joint system was used to create randomly polygon fractures referred to as Discrete Fracture Size (DFS). The coding of various parameters was performed to study the near-wellbore stability for both underbalanced and overbalanced drilling conditions, the four cases of DFS were used against seven wellbore pressures. After comparing with other DFS, The parametric analysis at DFS of 0.1 and 0.12 m offers low shear and block displacements that led to an induced shear and tensile failures, respectively. However, to evaluate the optimal DFS, a comparison is done using Failure area and Borehole enlargement analysis, and the results show that DFS of 0.12 m yields significantly low wellbore enlargement rate and failure area zone for all stress ratios and drilling cases. The proposed simple model for wellbore failure area estimations is verified against a well vertical section located in Northern China. [ABSTRACT FROM AUTHOR]
