“…Now it is the moment to try to break this barrier. e flexible structural system (FSS) emerges as a solution to the attempt of obtaining a structural system that supports a great adaptation to multiple constraints of volumetric design, as well as the possibility of making easy and affordable changes in the structure of a building, throughout its life [14].…”

The main aim of this research work is to design a structural system for building customization, through simple industrialized components. The system is able to adapt to different orthogonal geometries and presents the necessary flexibility to allow modifications over the structure of the building throughout its life. The so-named “flexible structural system” (FSS) is characterized by using only small industrialized components, handled by one person, which exhibit an easy and simple assembly. The new system proposes the use of just two different pieces named basic units (BUi) with only two possible thicknesses for any of them. The system is composed of only 5 different pieces. The generating process of the structural system is based on different combinations of the basic units (BUi) to obtain resistant members (RMn). These resistant members allow to build structural frames (F), and finally, the addition of structural frames allows to generate diaphanous volumes (DV) and obtain the desired structure for the building. The limit of structural length is set at 4.8 meters. Finally, an example is shown where a structure for a diaphanous volume is obtained, using the referred industrialized elements. This shows that the system is systematic and easy to understand by users. We want the users themselves to design and build their own home as well as make the necessary modifications throughout the useful life of the building. This is the final objective.

Menciptakan sebuah produk wajib melalui tahap pengembangan dan perancangan. Pada tahap ini seluruh komponen produk, biaya produksi, desain dan waktu perakitan diperhitungkan. Melalui desain dan evaluasi produk yang berkelanjutan, dimungkinkan untuk mengatasi tingkat kinerja perakitan produk dan kesulitan dalam proses perakitan, serta waktu dan biaya perakitan. Waftafel portabel secara manual merupakan konsep produk dimana alat yang dirancang lebih efektif dan efisien sehingga dapat meningkatkan higienitas daripada wastafel pada umumnya. Pada tahap pengembangan wastafel secara manual peneliti menambah fungsi dari sebuah wastafel yang semula proses keluarnya air dengan memutar kran dan dikembangkan dengan menambahkan pedal untuk menekan keluarnya air kran tersebut yang bernilai jualnya lebih tinggi sehingga pemanfaatkan barang yang tidak terpakai bisa menghemat biaya agar produk lebih ekonomis dan lebih efisien. Perancangan dan pengembangan produk ini menggunakan metode Design For Manufacturing and Assembly (DFMA). Metode DFMA merupakan metode yang digunakan untuk menentukan desain produk dengan waktu dan biaya yang terbaik. Secara umum, metode ini juga dapat digunakan dalam pengembangan untuk meningkatkan kualitas dan mengukur peningkatan desain produk wastafel. juga mengggunakan pedal untuk mempermudah pengguna untuk mengoperasikan. Diharapkan wastafel termasuk dikembangkan efisiensi desain lebih tinggi daripada desain wastafel dengan harapan dapat memberikan alternatif desain produk dalam mencapai produk berkualitas dan biaya produksi rendah.

“…The authors [24], propose a methodology that is validated by a redesign of a sheet metal industrial clock, in which the impact of sustainability is calculated from a comparison between an existing product and a new product. The implementation of the method in the case study demonstrates reductions of over 25% of product mass, energy consumed and CO2 footprint, and over 50% of theoretical assembly time and product complexity.…”

To remain competitive on the market with a developed product, it’s very important to analyze the manufacturing costs and times, from the concept stage of the product. Design for manufacturing and assembly (DFMA) is one of the engineering methods that can be applied to reduce manufacturing costs and times, right from the design stage, without compromising product performance and reliability. The 3D modeling of the tray was made in Solidworks, and for the analysis of it’s manufacture and assembly, the Boothroyd and Dewhurst principle and recommendations from the DFMA software were followed. This paper presents a case study for a subassembly called a tray, used in automatic vertical storage systems. For the redesigned model, substantial improvements were obtained, through cost reductions of 12% and an increase in design efficiency from 4.86 to 12.03. Product analysis using DFMA has proven to be a key point in the development of a product that meets engineers.
