Preliminary Study

Sketching is an activity that takes place throughout the engineering design process, and is often linked to design cognition. This preliminary study identifies different skills that contribute to a designer’s sketching ability and explores how those skills might be related to sketch fluency and design outcome. A positive correlation was found between the quantity of sketches produced and sketch skills that emphasize drawing facility, but a negative correlation was found between sketch quantity and a skill related to mechanism visualization. Sketching is sometimes considered a generic skill, but this study suggests that there are differences among the different types of sketching skills in the context of engineering design. No notable relationship was found between sketching ability and design outcome. Results also suggest that students provided with explicit instruction in sketching tended to draw more overall, although there are likely many other factors involved.

Positive Correlations

Previous studies have demonstrated the importance of sketching in design cognition, particularly in the early stages of engineering design. The goal of this preliminary study is to consider the role of a designer’s sketching ability and to examine the potential link between sketching skill and measures of engineering design performance. Sketching ability was evaluated on three distinct aspects relevant to engineering design: visual recall, rendering, and novel visualization. These evaluations were correlated with each other and with measures for sketch fluency, reviewer ranking, and design project outcome. The results of this study suggest that sketching skill is not comprehensive nor is it solely task based. Rather, a designer’s sketching ability lies between these two poles. Positive correlations were found between the quantity of sketches produced and two of the sketching skills that emphasize drawing facility, but a negative correlation was found between sketch quantity and a skill related to mechanism visualization. No conclusive correlations were found between the sketching skills and design outcome and reviewer ranking. This study's findings suggest an important interplay between a designer's ability to sketch and their ability to visualize in their heads or through prototypes. Results also suggest that designers who are given sketch instruction tended to draw more overall.

Concepts of precision engineering design process for optimal design where engineering sciences contribute in the successful good design are elaborated in this paper. Scientific theory, numerical methods and practicality are discussed in this paper. Factors necessary for a complete product or systems design are detailed and application of mathematical design optimization in producing a good design are shown. Many applicable engineering design examples are itemized to show relevancy of the optimal design theory to engineering design. Future trends of optimal design with respect to the 4th industrial revolution of digitization is presented. Paper sets to elaborate that most of the engineering and scientific design problems can be optimized to a good design based on many new/advanced optimization techniques.

Purpose The purpose of this study is to examine a week-long science, technology, engineering and mathematics (STEM) project-based learning (PBL) activity that integrates a new educational technology and the engineering design process to teach middle and high school students the concepts involved in rotational physics. The technology and teaching method described in this paper can be applied to a wide variety of STEM content areas. Design/methodology/approach As an educational technology, the dynamic and interactive mathematical expressions (DIME) map system automatically generates an interactive, connected concept map of mathematically based concepts extracted from a portable document format textbook chapter. Over five days, students used DIME maps to engage in meaningful self-guided learning within the engineering design process and STEM PBL. Findings Using DIME maps within a STEM PBL activity, students explored the physics behind spinning objects, proposed multiple creative designs and built a variety of spinners to meet specified criteria and constraints. Practical implications STEM teachers can use DIME maps and STEM PBL to support their students in making connections between what they learn in the classroom and real-world scenarios. Social implications For any classroom with computers, tablets or phones and an internet connection, DIME maps are an accessible educational technology that provides an alternative representation of knowledge for learners who are underserved by traditional methods of instruction. Originality/value For STEM teachers and education researchers, the activity described in this paper uses advances in technology (DIME maps and slow-motion video capture on cell phones) and pedagogy (STEM PBL and the engineering design process) to enable students to engage in meaningful learning.

Design Ideas

Information is transferred through a process consisting of an information source, a transmitter, a channel, a receiver and its destination. Unfortunately, during different stages of the engineering design process, there is a risk of a design idea or solution being incorrectly interpreted due to the nonlinearity of engineering design. I.e., there are many ways to communicate a single design idea or solution. This paper provides a comprehensive review and categorization of the possible sources of information loss at different stages of the engineering design process. Next, the authors present an approach that seeks to minimize information loss during certain stages of the engineering design process. The paper i) explores design process and dissemination methods in engineering design; ii) reviews prior work pertaining to these stages of the engineering design process and iii) proposes an information entropy metric that designers can utilize in order to quantify information loss at different stages of the engineering design process. Knowledge gained from this work will aid designers in selecting a suitable dissemination solution needed to effectively achieve a design solution.
