3d Anthropometry in Ergonomic Product Design Education

Abstract

The Faculty of Industrial Design Engineering of the Delft University of Technology offers a bachelor's degree education programme and three master's programmes. Our students are lectured in ergonomics and learn to design and conduct research in ergonomics. In this paper we describe the development of methods to realise ergonomic fit mapping based on 3D anthropometrics and to educate students on this topic. Due to the increasing availability of 3D scan data, we enter the complex field of 3D anthropometry and statistical shape models, which is an increasingly popular mathematical representation for 3D human shape variation. These facilities and knowledge are particularly useful when it comes to products that should fit close to the human body. The use of 3D anthropometrics is explained and practiced throughout the different stages of complexity. It starts with the use of 1D and 2D anthropometric data, the application of percentiles and the DINED tool Ellipse to see the correlation between two different body dimensions and to determine the consequences for related product dimensions. It ends with the use of 3D anthropometric data for the design of a helmet for cyclists, by way of bi-variate based shape analysis of the head. We made efforts to lower the burden for students working with 3D scan data, for example by providing pre-processed 3D scan databases and casus specific measurement tables.

Desarrollo de modelos estadísticos de predicción del ajuste y talla de prendas de ropa a partir de la percepción y características antropométricas del usuario

“…Con un formato más dinámico, que permite seleccionar el perfil de la población objetivo (género, edad, país) y los estadísticos de salida, la aplicación web DINED (Jellema et al, 2019;Johan Molenbroek, 2018) es una fuente de consulta interesante que permite obtener tablas antropométricas más enfocadas a aplicaciones concretas (Figura 64). Con una aproximación similar, el software 'PeopleSize' (Open Ergonomics, 2008) integra una recopilación de estudios antropométricos de 10 países (Austalia, Belgica, China,Francia, Alemania, Italia, Japón, Suecia, Reino Unido y EEUU).…”
