Design Requirements

Conceptual design is a critical design phase during which initial design solutions, called design concepts, are developed. These design concepts must be evaluated to ensure they satisfy the specified design requirements and the most appropriate design concept must be selected. It is often difficult for the designer, especially for the novice, to make an appropriate design concept evaluation and selection. Existing work on design evaluation lacks an effective tool for evaluating the temporal performance of the design concepts. To address this problem, a Critical Path Method (CPM) from project management is adapted for design evaluation, whereby a CPM network is converted from a causal behavioral process (CBP) and the methodologies relating to CPM are also applied to design improvement. A case study of a lever-clamp assembly system is also presented to illustrate as well as validate the method.

Probabilistic Entropy

Abstract Formal methods for conceptual design must embrace the uncertainty that pervades the earliest parts of the design process. Operating over this uncertainty, decision-based design measures the value of restricting the design space as well as the impact of refining design evaluation or analysis models. Missing from this framework is the cost in terms of design freedom of restricting the design space. We propose a measure of design freedom based on probabilistic entropy and demonstrate its application to two example conceptual design problems.

Collaborative Evaluation

In conceptual design, a number of design concepts and alternatives would be generated. These concepts and alternatives usually need to be evaluated to reduce the search space. However, it is not easy for the designers to determine which alternative is better, especially in the design environment where multiple designers might be involved. Current researches mainly focused on the evaluation models, but rarely provide the integrated tools to assist the evaluation process. To address this problem, we propose a web-based collaborative design evaluation platform and two evaluation principles for different evaluation situations. A design case is used to illustrate the evaluation process, where it is necessary for the designers to select a working phenomenon for the “generate force” subfunction of a nailing machine.

Positioning Errors

A microfactory is a system that can perform manufacturing processes within a very limited space such as a desktop. However, design optimization of miniature machine tools in microfactories have not been studied enough. Since the miniature machine tool designs are not supported by existing design experience as normal machine tools are, design guidelines for miniature machine tool are strongly demanded. And a design tool to analyze machine performance without prototyping will be also necessary because the miniature machines have wider design choices than normal machine tools have, based on its small size and less constraints. This paper focuses on a robust design tool combining form-shaping theory with the Taguchi method, to roughly estimate performance of miniature machine tools at its conceptual design stages. The effort not only identifies critical design parameters that have significant influence on the machining tolerance, but also determines which structure has the best theoretical performance. The paper tells that the proposing design evaluation method can help machine tool designers in determining the optimum structure of a miniature machine tool. The study also realizes two designs of miniature mills to measure positioning errors. The measurement ensures the design evaluation method can predict the machine performance well enough for usage in conceptual design stages. The paper concludes that the design evaluation method is applicable to a systematic miniaturization of a machine tool.
