Parametric Design of Urban Furniture Based on the Analytic Hierarchy Process
No full textAs an important component of public spaces, urban furniture meets the daily needs and cultural expressions of residents. It also significantly influences the aesthetic and practical value of urban environments. The research used an integrated approach of affinity diagram method (KJ method), analytic hierarchy process (AHP), and fuzzy comprehensive evaluation to conduct a systematic qualitative and quantitative analysis of urban seating design, assessing the importance of function, form, materials and regional features. By analyzing the integration of urban furniture design with regional features, this paper offers a multidimensional perspective for modern design. Based on the survey results, integration of regional cultural symbols and recreating historical scenes are key requirements that guided the parametric design of Harbin Westred Square’s seating furniture. It highlights the importance and potential of parametric design in innovating urban furniture and conveying the spirit of urban culture
Consumer Perceptions of Cultural Sustainability in Neo-Chinese Furniture: A Text Mining Analysis of Online Reviews from JD and Tmall
No full textThis study investigates how consumers perceive the cultural sustainability of Neo-Chinese furniture through the lens of online reviews on two major e-commerce platforms in China: JD.com and Tmall. Employing a mixed-methods approach combining Word2Vec modeling, qualitative content analysis, and a cultural semiotics framework, 47,766 reviews were evaluated across eight representative brands. Consumer perceptions were categorized into three cultural layers—tangible (e.g., material quality, design form), behavioral (e.g., functional use, craftsmanship), and intangible (e.g., aesthetic taste, historical symbolism). The data revealed that Tmall reviews were 23% more likely to mention aesthetic attributes (viz., style, elegance), while JD reviews contained 35% more references to functional features and material credibility (viz., “solid wood,” “durability”). However, references to intangible cultural dimensions—such as traditional narratives or symbolic meaning—accounted for less than 8% of all keyword clusters on both platforms. This indicates a shared deficit in deep cultural cognition. The paper concludes by proposing platform-specific strategies to enhance cultural communication and engagement, contributing to the broader discourse on sustainable design and digital cultural branding
Generative Design of Bamboo Furniture Combining Game Theory and AI-Generated Content
No full textConsumers tend to purchase and use furniture products that fulfill their emotional needs. However, existing bamboo furniture design departments lack a systematic and scientific approach to morphological design, and their innovation capabilities remain insufficient. This study proposes a generative design method for bamboo furniture that integrates Game Theory (GT) with AI-Generated Content (AIGC), grounded in Kansei Engineering. This approach aims to assist design departments in developing creative products that align with consumers’ emotional needs, thereby fostering sustainable consumption and advancing the bamboo furniture industry. First, consumer-driven Kansei words were collected and categorized. Then, subjective and objective weight values of consumer requirements were calculated using Grey Relational Analysis (GRA) and entropy, respectively. Based on GT, a comprehensive weight value was determined to accurately identify key consumer requirements. Next, Diffusion Models in AIGC technology were employed to generate new furniture images, followed by morphological deconstruction. Finally, a House of Quality based on Fuzzy Quality Function Deployment was constructed to establish the mapping relationship between key consumer requirements and new morphological elements, determining the optimal furniture design parameters. The proposed method integrates the strengths of both subjective and objective approaches, enhancing the accuracy and scientific rigor of design decision-making
Particleboard Surface Optimization for High-Quality Laminating with Decor Paper
No full textThe level of wood consumption is important in particleboard (PB) manufacturing because wood is a natural source. This study aimed to determine the optimum wood consumption in PB manufacture. The study examined how the PB's surface (SL) and core (CL) layer ratio and sanding tolerance affect the PB surface laminating condition. The optimal manufacturing conditions were determined among different combinations of PB density (520 or 560 kg/m3), SL/CL ratio, and sanding thickness using the multi-criteria decision-making method (MCDM). Grey relational analysis (GRA) was used as MCDM. Samples were characterized according to TS EN 312. The moisture content (MC) increased (30%) as the SL ratio increased. Thickness swelling (TS) and water absorption (WA) generally decreased as SL increased. Increasing surface layer density and board density significantly improved internal bond (IB) strength and surface stiffness (SS). Modulus of rupture (MOR) and elasticity (MOE) decreased as the sanding tolerance increased. Surface and edge screw withdrawal (SRy and SRk) resistance were increased as the density, sanding tolerance, and surface density increased. This study is the first comprehensive optimization approach to improve quality in coating low-density particle boards with decorative paper, potentially leading to material savings and production efficiency for the furniture and coating industries
The Sensual Intention of Wardrobe Furniture Materials Based on Women’s Visual and Tactile Experience Evaluation
No full textWith the rise of the ‘her economy’, the influence of women's consumer demand on furniture design is becoming increasingly important. The purpose of this study was to explore the relationship between female consumers’ visual and tactile perceptions of different wardrobe furniture materials and their psychological and sensory cognition. Based on the theory of Kansei engineering, a questionnaire was designed using a semantic differential scale and a seven-point Likert scale. Female participants were invited to rate 8 sets of perceptual vocabulary for 13 representative wardrobe furniture material samples through visual and tactile perception. SPSS 27 software was used to conduct reliability and validity tests, cluster analysis, and factor analysis on the experimental data. Cluster analysis categorized the materials into three types: natural flexible materials, patterned solid wood materials, and modern materials. Factor analysis identified two key dimensions: tactile perception and visual perception. These dimensions were used to analyze the differences in sensory cognition among the three material types in female consumers. This experiment provided theoretical support for the study of female consumers’ perceptual perception of wardrobe furniture materials, and at the same time provided rational references for designers to optimise the choice of materials in wardrobe furniture design based on the emotional needs of female users
Comparative Analysis of Fiber Characteristics and Chemical, Physical, and Mechanical Properties of Six Indigenous Bamboo Species from Indonesia
No full textBamboo is a versatile, sustainable resource used in industries such as construction, furniture, textiles, and paper. Its species vary in properties, influencing their suitability for specific applications. This research aimed to perform a comparative analysis of the fiber characteristics and chemical properties of Indonesian bamboo species from the genera Gigantochloa, Schizostachyum, and Bambusa. Pearson’s correlation analysis was performed to quantify associations among fiber characteristics, chemical composition, and mechanical performance. The results indicated that Bambusa presented the greatest fiber density, whereas Gigantochloa presented superior fiber dimensions, and Schizostachyum presented intermediate values. The mechanical properties of the fibers were inversely related to density. Bambusa showed the highest fiber dimensions, followed by Schizostachyum, whereas Gigantochloa presented the lowest scores, with the exception of the flexibility ratio. All the species, notwithstanding their variation, satisfied the criteria for fiber quality class II. The Bambusa species presented the highest contents of holocellulose, α-cellulose, and hemicellulose, followed by Gigantochloa and Schizostachyum. The highest concentration of starch was found in Schizostachyum, followed by Gigantochloa, and then Bambusa. Notably, G. serik, S. brachycladum, and B. blumeana have demonstrated considerable potential for pulp and paper applications, similar to traditional pulpwood species
Integrated Analysis of Cork Presence in Korean Oak Barks Using Visual Inspection, Colorimetry, FT-IR, and Py-GC/MS
No full textSix oak species are native to Korea, but a visible cork layer is present only in Quercus variabilis. This study presents a chemical analysis approach—including colorimetric analysis, FT-IR, and Py-GC/MS—to compare the cork composition of six Korean oak species: Quercus acutissima, Q. aliena, Q. dentata, Q. mongolica, Q. serrata, and Q. variabilis. The analysis focuses on suberin and lignin, the main cork components, by identifying their pyrolysis products. Methanolysis with 3% NaOCH₃ extracted suberin monomers, revealing approximately 20% suberin content in all species except Q. variabilis, which showed around 40%. Py-GC/MS differentiated suberin-derived fatty acids—found exclusively in cork tissue—from other fatty acids present in the rhytidome. Q. variabilis exhibited 2–8 times higher levels of suberin-derived fatty acids and abundant lignin monomers, mainly guaiacyl (G) units. In contrast, lignin monomers were undetectable in Q. acutissima, Q. aliena, and Q. dentata, suggesting either very low levels or concentrations below the instrument’s detection limit. Syringyl (S) monomers were also absent in Q. mongolica and Q. serrata. These findings suggest that lignin composition, along with visual cork layer assessment, can help evaluate the cork potential of Korean oak species and identify viable substitutes for commercial cork
Enzymatic Suppression of Postharvest Fungi in Tomato Fruits: In-vitro and In-silico Evidence of Chitinase and β-1,3-Glucanase Efficacy
No full textSpoiled tomato fruits exhibited fungal infections, and the isolates were identified as Penicillium expansum, Alternaria alternata, Aspergillus terreus, and Fusarium oxysporum. Varying doses of chitinase, β-1,3-glucanase, and a chemical fungicide were tested against four fungal pathogens. All treatments showed dose-dependent inhibition of fungal growth. The chemical fungicide caused complete inhibition at the highest dose, while chitinase and β-1,3-glucanase significantly reduced colony size, especially in P. expansum and A. alternata, though they were less effective against A. terreus and F. oxysporum. This study rigorously investigated the molecular docking interactions of chitinase (PDB ID: 1CTN) and β-1,3-glucanase (PDB ID: 4M80), with target proteins of F. oxysporum (PDB ID: 7T69). Molecular simulations revealed compelling binding affinities, with chitinase demonstrating a docking score of -82.67 kcal/mol and β-1,3-glucanase exhibiting a score of -78.1 kcal/mol. Detailed interaction analyses revealed distinct binding mechanisms: Chitinase forms a stable complex through multiple hydrogen bonds and significant π-π stacking with key residues such as TRP210, while β-1,3-glucanase employs extensive hydrogen bonding and strong ionic interactions, notably with GLU121, for electrostatic stabilization. These findings provide critical molecular insights into the antifungal capabilities of these enzymes, highlighting their potential as agents to combat postharvest fungal pathogens
Morphological Remodeling and Performance of Cured Tannin-Sucrose Adhesive Layer: Enhancement by Catalyst
No full textNew adhesives were developed using sustainable bayberry tannin and sucrose as raw materials. Through introducing three catalysts—citric acid, p-toluenesulfonic acid, and phytic acid—a comprehensive analysis of their differential impact mechanisms on catalyzing sucrose conversion, promoting cross-linking reactions, and shaping the microstructure of the adhesive was conducted. The results showed that under the phytic acid catalytic system, the yield of 5-hydroxymethylfurfural (5-HMF) reached 17.5 μg/mL, which was higher than that of p-toluenesulfonic acid (14.1 μg/mL) and citric acid (12.9 μg/mL). The introduction of catalysts led to a stepwise improvement in the mechanical properties of the adhesive. The adhesive catalyzed by phytic acid exhibited excellent bonding strength and water resistance, reflecting its advantage in promoting deep cross-linking between 5-HMF and tannin. Scanning electron microscopy results intuitively demonstrated the reshaping of the adhesive layer morphology by the catalysts, evolving from the loose and porous structure of the blank group to a dense, wrinkled morphology after the action of the catalysts. The results of thermogravimetric analysis further quantified the enhancement effect of the catalysts on the thermal stability of the network structure, with the three-dimensional network structure built by the phytic acid system exhibiting superior thermal protection capabilities
Optimization of Flame Retardant System for Waste Tetra Pak/Bamboo Fiber Composites with Inorganic Flame Retardants
No full textTetra Pak (TP)/bamboo fiber (BF) composites were prepared using waste TP and bamboo fiber as the main raw materials. Twelve inorganic flame retardant systems were used to modify the flame retardancy of TP/BF composites. Specimens were evaluated with the limiting oxygen index test, water absorption test, dry shrinkage and wet expansion test, mechanical property test, and Fourier transform infrared spectroscopy (FTIR). The results showed that the composite flame retardant systems outperformed the single flame retardant system, with the limiting oxygen index reaching up to 37.6%. Retardant addition lowered the modulus of elasticity (MOE), modulus or rupture (MOR), and internal bond (IB) and impaired dimensional stability, the extent varying with type and dosage. Among them, the TP/BF composites modified by systems Z3, Z8, Z9, and Z12 satisfied GB/T 11718-2021requirements for ordinary, furniture, and building medium-density fiberboards. FTIR showed the presence of chemical bonds of various functional groups that would be consistent with the development of adhesion within the composite
