AbstractA new design methodology for long life and large size (Ll-Ls) products called Design for Installation (DfI) is proposed. Ll-Ls products are usually made up of large parts that need to be assembled on field. The proposed methodology, based on adapted Design Structure Matrix (DSM) and Design for Manufacturing and Assembly (DfMA) methods, enables to optimize the design of a Ll-Ls product in order to reduce time and cost of the installation process. The new methodology works with a conceptual design of the product and the weight and size restrictions given by logistic factors as inputs.
A method to select a key HOQ of QFD from the existed HOQs for variety of design is introduced first. Evolution of technique (ET) is used to find exciting requirements for the product to be designed and VOC driven by ET is formed. A new conceptual design model is illustrated, which integrate VOC driven by ET, QFD, inventive principles and separation principles of TRIZ. A design example is carried out using the model.
