Comparing furniture joint variants using a multi-criteria analysis

Abstract

This research article compares selected furniture joints. The first part focuses on conventional joining techniques, including cam and dowel joints, and the second part discusses innovative joints, primarily plastic ones. The article also describes new connectors that allow simple assembly of furniture. The research deals with several parameters in a multi-criteria analysis: bending moment capacity under compression, bending moment capacity under tension, price of fasteners, machining time, assembly time, visibility and dismountability. Spearman's rank correlation coefficient is also used in the research, proving that there is a correlation between different parameters of the joints. This study aims to compare the performance of furniture joints based on various parameters, including strength, cost, and ease of assembly. The study looks at the individual connections from a different perspective, which can also be evaluated by users. The aim of the study was to evaluate the individual connections from several perspectives. Another aim was to find out whether the individual parameters interact or not. The utilization of a multi-criteria analysis enables furniture manufacturers to make informed decisions regarding joint selection and production processes.
