“…With dependence on the type of chair construction, the joint between the side rail and back leg or the seat-back joint is the most stressed joint [86][87][88]. This fact was confirmed in the process of lamella chair construction with the stress concentrated especially in the mold of seat frame.…”

The research on population shows that the count of overweight people has been constantly growing. Therefore, designing and modifying utility items, e.g., furniture should be brought into focus. Indeed, furniture function and safety is associated with the weight of a user. Current processes and standards dealing with the design of seating furniture do not meet the requirements of overweight users. The research is aimed at designing flexible chairs consisting of lamellae using the finite element method (FEM). Three types of glued lamellae based on wood with different number of layers and thickness were made and subsequently, their mechanical properties were tested. Values for modulus of elasticity and modulus of rupture were used to determine stress and deformation applying the FEM method for modelling flexible chairs. In this research, the methodology for evaluating the ultimate state of flexible chairs used to analyse deformation and stability was defined. The analysis confirms that several designed constructions meet the requirements of actual standards (valid for the weight of a user up to 110 kg) but fail to meet the requirements for weight gain of a population.

“…In addition to durability, the wooden structure has stability against settlement and strong earthquake resistance. Recently, researchers have explored the specific properties of wood structure joints through quantitative calculation and analysis (Ke et al 2017). Iringová and Idunk (2017) performed static analysis on an existing load-bearing structure, and the strength of the structure was evaluated.…”

Wooden structure and the process of extracting elements are performed together with the adolescent. Young people have gradually forgotten ancient wisdom hidden in traditional objects. Traditional East Asian wooden architecture use mortise-and-tenon joints with various types. We have summarized the main types of wood structure joints and selected joint styles for image perception analysis. First, the joint structure is simplified, and the CAD digital model of the objects was established to facilitate the understanding of its structures and assembly approach. Second, connecting elements were extracted into five functions and shape types. Four stages questionnaires were used to survey feedback to verify the main recognizable features. The initiative's primary intended outcome is 30 adjective with each sample which have differences in their cognition. After summing up by factor analysis, they can more clearly know the difference in image cognition between mortise-and-tenon samples.
