Do it yourself furniture: Part A - Designing fittings for an easy to manufacture hybrid chair

Abstract

Traditional productions of goods are being changed by technological advances. Furniture production also takes its portion from this either positive or negative manner. Because either traditional wood material preparing ways or design and manufacturing of fittings are being changed by the technological software and hardware. The do-it-yourself perspective of additive manufacturing applications emerges as a reflection of these advances and changes. Different types of connectors were designed and manufactured for a specific joint of a chair by previously published studies. However, in this study, four different connector types were designed for properly assemble of a chair instead of element joint in accordance with the do-it-yourself perspective. CATIA software was used for three-dimensional modeling and assembly. Dowels were applied to each joint for strengthening chair construction. Wooden elements were designed without curves to provide easy-to-manufacture chairs for end-users who have limited knowledge about wood joinery. Views and sections were included for presenting the assembly details. Some construction add-ons such as an upholstery seat and a backrest with a proper slope were offered to improve the comfort issue that arises from the straight-line design approach.

Kendin yap mobilya: Bölüm A – Kolay imal edilebilir melez sandalye için bağlantı elemanları tasarımı

Abstract

Teknolojik gelişimlerle birlikte ürünlerin geleneksel imalat şekilleri değişmektedir. Mobilya imalatı da bundan olumlu ya da olumsuz anlamda payını almaktadır. Çünkü gerek geleneksel ahşap malzeme hazırlama gerekse de bağlantı elemanı tasarım ve üretimi teknolojik yazılım ve donanımlarla değişime ve gelişime uğramaktadır. Eklemeli imalat ile kendin yap anlayışı da bu gelişim ve değişimin yansımalarından biri olarak karşımıza çıkmaktadır. Önceki çalışmalarda genellikle sandalyenin belli bir bağlantısı için farklı tip elemanlar tasarlanıp üretilmiştir. Fakat bu çalışmada, kendin yap anlayışı doğrultusunda bir sandalye montajının tam olarak yapılmasını sağlamak için dört farklı bağlantı elemanı tasarlanmıştır. Üç boyutlu modelleme ve montaj için CATIA yazılımı kullanılmıştır. Sandalye konstrüksiyonunu güçlendirmek için her bir bağlantı noktasına kavelalar uygulanmıştır. Ahşap parçalar, ahşap doğramacılığı hakkında kısıtlı bilgiye sahip olan nihai kullanıcıların bir sandalyeyi rahatlıkla imal edebilmesi için herhangi bir kavis olmadan tasarlanmıştır. Sandalye montaj detaylarını göstermek için görünüşler ve kesitlere yer verilmiştir. Uygun eğimlere sahip takılıp çıkarılabilir döşemeli oturak ve sırtlık gibi bazı konstrüksiyon eklentileri düz hatlı tasarım yaklaşımı nedeni ile ortaya çıkan konfor meselesini iyileştirmek için önerilmiştir.
