Abstract

Purpose

The purpose of this paper is to decrease musculoskeletal disorder (MSD) problems using a combined approach including design for Six Sigma, generic product development process, and ergonomic-safety philosophies.

Design/methodology/approach

A total of 550 students voluntarily participated in this study. Kolmogorov–Smirnov and t-tests were used to analyze the collected anthropometry. A cause-and-effect diagram, Pareto’s chart, a brainstorming session, and a priority matrix were also used to extract the 22 design parameters of the product. Moreover, Cronbach’s alpha values were determined to verify the validity of qualitative and quantitative data.

Findings

Results showed that students are at a high risk of developing MSD issues. The most serious MSD problems among the students were neck pain (74%), back pain (73%), muscle and joint pain (67%), knee pain (57%), leg pain (54%), etc. Besides, all anthropometrics of males are higher than females except Hip Breadth. Among 12 anthropometries, two measurements and one measurement showed statistical significance at p < 0.01 and p < 0.05, respectively. Six design parameters of the mounted desktop (Seat Height, Desk Height, Seat to Desk Clearance, Seat Width, Seat Depth, and Backrest Height) are the most crucial design parameters to design and develop the product.

Practical implications

The proposed design of the mounted desktop can be used in different tertiary educational institutes to reduce MSDs among students.

Originality/value

To the best of the authors’ knowledge, this is the first attempt that introduces a combined approach to reduce MSD issues by applying Six Sigma, a generic product development process, and ergonomics-safety philosophy to design and measurement of 22 design parameters of mounted desktop for university students.
