Diseño de un portaconos adapble a máquinas de coser caseras marca Singer modelos 4423, 4411, 4432 y 6335M

Abstract

This document shows the development of a functional cone holder design adaptable to the range of Singer brand home sewing machines using the original factory cone holder. This design aims to solve the problem present in this type of machines corresponding to the impossibility of implementing a large cone in the sewing operation, this is because the accessories available on the market are not compatible with this type of machines or with this type of cones. The development of cone holder is based on the implementation of a QFD matrix (Quality Function Deployment), whose information was collected through a survey to users; the 3D printing and testing stages are also shown, going through the design and calculation stages necessary to reach the satisfactory functional results obtained.
