The purpose of this paper is to combine the consumer needs and design decisions for redesigning a Foil sealer which is existing Bangladeshi market. Quality Function Deployment (QFD), functional decomposition is used to frame a formal optimization model that links product design and marketing decision making models by defining and coordinating interactions between the two. The redesigning of the Foil sealer is implemented using popular Quality Function Deployment (QFD) based approach. It is found out that the existing product suffered from some drawbacks mainly temperature control and heat management. A QFD model is defined in order to expand the services provided by an existing Foil Sealer in market which is congruent with the consumer needs. The model would reflect the impact of overriding characteristics of the new product. New components are introduced and modifications were made to the existing design to accommodate the customer needs. These new characteristics of components are analyzed using 3D diagrams. This paper describes the efficacy of the QFD based approach to investigate the customer needs and modification of an existing product.
