Should Optimal Designers Worry About Consideration?
(The American Society of Mechanical Engineers (ASME), 2015)Consideration set formation using noncompensatory screening rules is a vital component of real purchasing decisions with decades of experimental validation. Marketers have recently developed statistical methods that can ... -
A Data Driven Network Analysis Approach to Predicting Customer Choice Sets for Choice Modeling in Engineering Design
(The American Society of Mechanical Engineers (ASME), 2015)In this paper, we propose a datadriven network analysis based approach to predict individual choice sets for customer choice modeling in engineering design. We apply data analytics to mine existing data of customer choice ... -
Requirements Development: Approaches and Behaviors of Novice Designers
(The American Society of Mechanical Engineers (ASME), 2015)Elicitation and development of product requirements are crucial aspects of frontend design and have significant impacts on future product success. This study sought to better understand how novice designers approach the ... -
Products' Shared Visual Features Do Not Cancel in Consumer Decisions
(The American Society of Mechanical Engineers (ASME), 2015)Consumers' product purchase decisions typically involve comparing competing products' visual features and functional attributes. Companies strive for “product differentiation†(Liu et al., 2013, “Product Family Design ... -
Connections Between the Design Tool, Design Attributes, and User Preferences in Early Stage Design
(The American Society of Mechanical Engineers (ASME), 2015)Gathering user feedback on provisional design concepts early in the design process has the potential to reduce timetomarket and create more satisfying products. Among the parameters that shape user response to a product, ... -
Communicating Consumer Needs in the Design Process of Branded Products
(The American Society of Mechanical Engineers (ASME), 2015)User preferences in design process of branded products are addressed through several layers of mediation occurring at the interfaces between consumers, product designers, and engineering designers, whereby product designers ... -
Pattern Analysis of IDEO's Human Centered Design Methods in Developing Regions
(The American Society of Mechanical Engineers (ASME), 2015)While there is increasing interest in designing for the developing world, identifying appropriate design research methods for understanding user needs and preferences in these unfamiliar contexts is a major challenge. This ... -
Developing World Users as Lead Users: A Case Study in Engineering Reverse Innovation
(The American Society of Mechanical Engineers (ASME), 2015)This paper examines the “reverse innovation†of the leveraged freedom chair (LFC), a highperformance, lowcost, offroad wheelchair originally designed for developing countries. A needs study of 71 developed world ... -
Large Scale Needfinding: Methods of Increasing User Generated Needs From Large Populations
(The American Society of Mechanical Engineers (ASME), 2015)Understanding user needs and preferences is increasingly recognized as a critical component of early stage product development. The largescale needfinding methods in this series of studies attempt to overcome shortcomings ... -
Special Issue: User Needs and Preferences in Engineering Design
(The American Society of Mechanical Engineers (ASME), 2015)Addressing user needs and preferences is critically important in developing innovative and successful engineered products and systems. The task is inherently challenging due to the heterogeneity of user needs and the ... -
Latent Customer Needs Elicitation by Use Case Analogical Reasoning From Sentiment Analysis of Online Product Reviews
(The American Society of Mechanical Engineers (ASME), 2015)Different from explicit customer needs that can be identified directly by analyzing raw data from the customers, latent customer needs are often implied in the semantics of use cases underlying customer needs information. ... -
Design and Analysis of a Novel Centrifugal Braking Device for a Mechanical Antilock Braking System
(The American Society of Mechanical Engineers (ASME), 2015)A new concept for a mechanical antilock braking system (ABS) with a centrifugal braking device (CBD), termed a centrifugal ABS (CABS), is presented and developed in this paper. This new CBD functions as a brake in which ... -
Automated Discovery of Lead Users and Latent Product Features by Mining Large Scale Social Media Networks
(The American Society of Mechanical Engineers (ASME), 2015)Lead users play a vital role in next generation product development, as they help designers discover relevant product feature preferences months or even years before they are desired by the general customer base. Existing ... -
Design of a Portable Compliant Device for Estimating the Failure Load of Mesoscale Cemented Sand Specimens
(The American Society of Mechanical Engineers (ASME), 2015)In this paper, we present the design and development of a portable, handoperated composite compliant mechanism for estimating the failureload of cmsized stiff objects whose stiffness is of the order of 10 s of kN/m. The ... -
Docking Robustness of Patient Specific Surgical Guides for Joint Replacement Surgery
(The American Society of Mechanical Engineers (ASME), 2015)In joint replacement surgery, patient specific surgical guides (PSSGs) are used for accurate alignment of implant components. PSSGs are designed preoperatively to have a geometric fit with the patient's bone such that the ... -
Turning Functions in Optimal Synthesis of Mechanisms
(The American Society of Mechanical Engineers (ASME), 2015)In this paper, we describe the use of turning functions to compare errors between the coupler and the target paths. The main reason to use turning functions is that the measured error does not depend on the mechanism scale ... -
Screw System Variation Enabled Reconfiguration of the Bennett Plano Spherical Hybrid Linkage and Its Evolved Parallel Mechanism
(The American Society of Mechanical Engineers (ASME), 2015)This paper presents the Bennett planospherical hybrid linkage and proposes a novel metamorphic parallel mechanism consisting of this planospherical linkage as part of limbs. In light of geometrical modeling of the Bennett ... -
Analytical Investigations on the Mesh Stiffness Function of Solid Spur and Helical Gears
(The American Society of Mechanical Engineers (ASME), 2015)Approximate formulae are presented which give the timevarying mesh stiffness function for ideal solid spur and helical gears. The corresponding results compare very well with those obtained by using twodimensional (2D) ... -
