Design and development of appropriate desk and chair for secondary schools in Ondo State, Nigeria using anthropometric variables

Abstract

Furniture provision is a major component of teaching and learning facilities in schools which is usually done without considering the body measurements of users leading to discomfort for the users. A survey of anthropometric measurements of secondary school students in Ondo State of Nigeria was carried out alongside the size of existing chairs and desks in order to determine the level of mismatch. Obtained data were analyzed and the population of students was grouped into 5th, 25th, 50th, 75th, and 95th percentiles. In Ondo State, Bio-characteristics of the students showed that the average age of students from JSS 1-SSS 3 increased from 10 years for JSS 1 to 16 for SSS3 which conformed with the entry and exit age requirement. Ergonomically compliant furniture was designed with adjustable features using 36.25 cm as the lower limit point and with the upper limit of 46.85 cm for seat height while lower limit was 54.46 cm for desk and upper limit having 67.60 cm. With these measurements, a typical desk and chair was produced by using round pipe and laminated board. Selection of non-adjustable furniture is both impracticable and unsuitable for a large of people; hence provision of adjustable compliant furniture was preferred to accommodate the entire population.

Antropometrik değişkenler kullanılarak Nijerya'nın Ondo eyaletindeki ortaokullar için uygun sıra ve sandalye tasarımı ve geliştirilmesi

Abstract

Mobilya tedariki, okullarda genellikle kullanıcıların vücut ölçüleri dikkate alınmadan yapılan ve kullanıcıları rahatsız eden öğretim ve öğrenim tesislerinin önemli bir bileşenidir. Uyumsuzluk düzeyini belirlemek için Nijerya’nın Ondo eyaletindeki ortaokul öğrencilerinin antropometrik ölçümlerine ilişkin bir anket, mevcut sandalye ve sıraların boyutlarına göre gerçekleştirildi. Elde edilen veriler analiz edildi ve öğrenci popülasyonu 5., 25., 50., 75. ve 95. yüzdelik gruplara ayrıldı. Ondo eyaletindeki öğrencilerin biyo-özellikleri, JSS 1-SSS 3'teki öğrencilerin ortalama yaşının, giriş ve çıkış yaşı gerekliliğini karşılayan JSS 1 için 10 yıldan SSS3 için 16’ya çıktığını gösterdi. Ergonomik uyumlu mobilyaların alt sınır noktası 36,25 cm, oturum yüksekliği üst sınırı 46,85 cm, çalışma masası alt sınırı 54,46 cm ve üst sınırı 67,60 cm olacak şekilde ayarlanabilir özellikte tasarlanmıştır. Bu ölçüler ile yuvarlak boru ve lamine levha kullanılarak tipik bir masa ve sandalye üretilmiştir. Büyük bir insan grubu için ayarlanamayan mobilya seçimi hem uygulanamaz hem de uygun değildir; bu nedenle, tüm nüfusu barındırmak için ayarlanabilir uyumlu mobilyaların sağlanması tercih edildi.
