(The American Society of Mechanical Engineers (ASME), 2014)This paper reports on a linear actuation mechanism in the form of a parallelcrank mechanism (i.e., doublecrank mechanism) articulated with two dielectric elastomer actuators working in parallel that are fabricated as a ... -
Using Singularities of Parallel Manipulators to Enhance the Rigid Body Replacement Design Method of Compliant Mechanisms
(The American Society of Mechanical Engineers (ASME), 2014)The rigidbody replacement method is often used when designing a compliant mechanism. The stiffness of the compliant mechanism, one of its main properties, is then highly dependent on the initial choice of a rigidbody ... -
Market Simulation Based Sensitivity Analysis as a Means to Inform Design Effort as Applied to Photovoltaic Panels
(The American Society of Mechanical Engineers (ASME), 2014)Product design success depends on the engineering performance of the product and also on the reaction of external stakeholders such as customers, retailers, and policymakers. This article illustrates how an earlystage ... -
Continuous Preference Trend Mining for Optimal Product Design With Multiple Profit Cycles

The Equal Bending Strength Design of Space Curve Meshing Wheel
(The American Society of Mechanical Engineers (ASME), 2014)The space curve meshing wheel (SCMW) has been studied previously for small power transmission. To extend its application in conventional power transmission, the bending strength of the SCMW needs to be studied. In this ... -
Estimating Local Decision Making Behavior in Complex Evolutionary Systems
(The American Society of Mechanical Engineers (ASME), 2014)Research in systems engineering and design is increasingly focused on complex sociotechnical systems whose structures are not directly controlled by the designers, but evolve endogenously as a result of decisions and ... -
Effects of Product Attributes in Case Based Reasoning Methods for Cost Estimation and Cost Uncertainty Modeling
(The American Society of Mechanical Engineers (ASME), 2014)This paper presents casebased reasoning methods for cost estimation and cost uncertainty modeling that may help designers select a new product concept at the early stage of product development. The casebased reasoning ... -
Design of the Curved Flank for the Star Wheel Tooth in Single Screw Compressors
(The American Society of Mechanical Engineers (ASME), 2014)The wear of starwheel teeth is an important problem in single screw compressors. In order to prolong the service life of star wheels, a new curved flank of the tooth is proposed. Section profile of the tooth flank is a ... -
A Descriptor Based Design Methodology for Developing Heterogeneous Microstructural Materials System
(The American Society of Mechanical Engineers (ASME), 2014)In designing a microstructural materials system, there are several key questions associated with design representation, design evaluation, and design synthesis: how to quantitatively represent the design space of a ... -
An Experimental Investigation of the Effectiveness of Empathic Experience Design for Innovative Concept Generation
(The American Society of Mechanical Engineers (ASME), 2014)An important part of designing successful products is building empathy for the people for whom the product is intended. Despite recent interest in empathic design techniques, they remain confined primarily to customer needs ... -
The Deviation Function Method of Rotary Engine Design by Geometric Parameters
