Industrial and technical products have traditionally been designed from two complementary perspectives. The other has focused on functionality and the other on external appearance. Research on usability and human-centric design has partially bridged the gap by integrating cognitive and contextual considerations with emotional, semantic, and esthetic considerations. This paper argues that to fil...

Tolerancing is one of the most important tools for planning, controlling, and improving quality in the industry. Tolerancing conducted by design engineers to meet customers’ needs is a prerequisite for producing high-quality products. Engineers use handbooks to conduct tolerancing. While use of statistical methods for tolerancing is not a new concept, engineers often use known distributions, in...

Plastics product design is very experience dependent process. In spite of various computer tools available on the market, the designer has to rely on personal or supporting experts’ knowledge and experience when designing plastics products. Proposed development of the intelligent advisory system presented in this paper involves two methodologies. “Design for X” strategy will be applied to consi...

In interactive design processes, strategic decisions are made at different levels. To support designers, design support systems need to include corresponding strategic knowledge at these levels. In this paper three levels of strategic interaction and strategic knowledge are identified within a compositional model of design. These levels are identified in reasoning about the manipulation of requ...

Adders and multipliers are two main units of the computer arithmetic processors and play an important role in reversible computations. The binary multiplier consists of two main parts, the partial products generation circuit (PPGC) and the reversible parallel adders (RPA). This paper introduces a novel reversible 4×4 multiplier circuit that is based on an advanced PPGC with Peres gates only. Ag...

How to make healthcare products and systems fit the work they are to support is a question that has received growing attention over the last decade. In most of the studies trying to answer this question, engineers put an effort to provide the best possible technical solution, but they dispose the important position of users. Design studies in different domains indicated a focus on the users and...

In this paper, our experience in developing learner-centered technical review techniques in programming courses is described. To better serve educational purposes, our learner-centered technical reviews define review artifact, review outcomes, expectation and format, etc according to the levels of programming course. Our learner-centered technical reviews have been proven to be very effective i...

The paper highlights the importance of design in product innovation, using portable computers as an empirical case study. This is an attempt to redress the balance in the innovation and product technology literature, which has overwhelmingly focused on hardware technologies (technical characteristics) of products. Principal components analysis is used to identify clusters of design characterist...
