Obtaining sustainable production from the product design analysis

Abstract Analysis of a product’s assembly properties is needed during the initial design stage in order to identify potential assembly problems. These problems affect product performance in the later stages of a product’s life cycle. An analysis methodology has been developed that supports product design analysis for assembly during the initial design stage. The methodology, referred to as the Assembly Design Evaluation Metric (ADEM), utilizes the incomplete nature of initial design data and a generic model of assembly operations in the analysis of a product design. ADEM generates ratings for each component of a product design and each process that would be needed to assemble the components together. From the individual component and process ratings, ADEM computes overall ratings for the product design itself. These overall product ratings can then be used to compare the differing iterations of a product design. Because ADEM provides an explicit model of assembly operations, different levels of data and process abstraction can be maintained and analyzed. This enables ADEM to evaluate product designs earlier in the design stage than existing design analysis methods such as DFA (design for assembly) techniques.

Reuse of existing design knowledge is the key to realize rapid product design. Analysis of present knowledge capture, representation and reuse method as well as study of static and dynamic knowledge capture method, the design template as a carrier for knowledge expression and reuse method is proposed. A typical instance for small agricultural machinery product is given to demonstrate the feasibility of the design approach.

Informed Decisions

This article discusses it has become a basic assumption that prices do not rise but instead they should fall in the economics of electronic products. It was precisely to meet customers’ expectations of lower prices that a Canadian manufacturer went to an essentially mechanical redesign of a telecommunications device. Nortel’s work on the redesign followed the principles of a system called DFMA, or design for manufacture and assembly, a design analysis tool developed by Boothroyd Dewhurst Inc., Wakefield, RI. It enables product designers to pinpoint parts and assemblies that add unnecessary costs to a product, and then design to avoid them. DFMA is designed to give engineers a structured way to evaluate ease of assembly and the overall manufacturability of a product. Design for assembly requires the user to assess whether each part is necessary, and to consider the time and cost of assembling the product. Design for manufacture integrates information about manufacturing processes, allowing users to estimate manufacturing costs and make informed decisions about materials.
