Effective training can be achieved in a safe and stress-free space in classrooms ( 2).
University is one of the educational settings in training of students. A chair with such characteristic can be used by many students with different body sizes.Įducation is the most effective means to ensure economic growth and national development in countries ( 1). Some ergonomic characteristics of this chair include adjustability of footrest, backrest, armrests, and desk. Such chair can reduce musculoskeletal disorders in students. The width and height of the backrest were also 54 cm and 44 cm, and the backrest angle was adjustable in 95° to 105°.Īn ergonomic chair with adjustable parts was designed to achieve a well-match between anthropometric characteristics of students and the furniture. The height of the desk was adjustable in 19 to 29 cm, and the depth and length of the desk were considered as 51 cm and 65 cm. The seat height, depth, and width of the chair were determined as 44 cm, 42 cm, and 42.15 cm, respectively. In this study, an ergonomic chair was designed based on anthropometric data from students.

The chair was planned in the CATIA software and developed by a three-dimensional print. The data were analyzed using the SPSS 20 software, and the results were extracted as mean, standard deviation, and percentiles. The aim of this study was to design and develop an ergonomic chair, based on anthropometric data of students in educational settings.Īnthropometric parameters were obtained from a stratified-random sample of 207 students. 4, pp.Proper designing of chairs based on ergonomics increases efficiency, promotes quality of education, leads to correct posture in students, and reduces risk of musculoskeletal disorders. Keywords: Workstation table, anthropometry, Digital Human Modelling (DHM), Rapid Upper Limb Assessment (RULA), footwear It also helps to reduce occupational risks by easing uncomfortable work positions. The proposed workstation and work layout are helpful to improve the accessibility of required tools and materials to footwear workers. CONCLUSION:The anthropometric database proposed in this study is likely to be useful in designing Kolhapuri footwear manufacturing tools. The virtual ergonomics assessment of this design revealed that the vision, thigh clearances, and RULA scores were satisfactory in the new design. The design was evaluated for thigh clearance, vision analysis and RULA analysis with the help of Digital Human Modelling (DHM). This work proposed a novel workstation design to reduce the high risk of MSDs. RULA scores suggested that ‘a change in posture’ to improve the efficiency of artisans was required for most of the workstations. RESULTS:It was observed that the entire footwear making activity was carried out in awkward postures. Rapid Upper Limb Assessment (RULA) was used for postural analysis of the artisans. This work measured 35 different body dimensions of the footwear manufacturing artisans. METHODS:An anthropometric database for the Kolhapuri footwear making population was developed. The work further aimed to improve the design of current workstations and evaluate the proposed design using virtual ergonomic assessment techniques. OBJECTIVE:The main objective was to study and assess different footwear manufacturing workstations and working postures. Due to the nature of the job, workers occupy various apparent non-optimal postures that may cause multiple work-related disorders such as musculoskeletal disorders (MSDs). Therefore, any occupational hazard-related documentation is not available. Workers of this craft use traditional methods and work in cottage-based enterprises where organized laws and legislations are not applicable. Artisans using traditional tools manufacture this footwear manually. It is a well- designed craft used by Indian people for many years. Kolhapuri footwear is a popular handmade craft in India. In the Indian footwear production industry, there is an enormous potential for employment, export, and development. Ībstract: BACKGROUND:The footwear manufacturing industry is one of the significant sectors of leather businesses in India. | Salve, Urmi RavindraĪffiliations: Department of Design, Indian Institute of Technology (IIT) Guwahati, Guwahati, Assam, IndiaĪddress for correspondence: Ganesh Suresh Jadhav, Department of Design, Indian Institute of Technology (IIT) Guwahati, Guwahati 781039, Assam, India.
