Appearance Design

Appearance design is becoming an increasingly important factor for determining product value as well as product functions as customer preference continues to diversify, leading to growing demands for sophisticated designs. Current CAD systems are not effective for design because they lack functions to express the designer’s sensitivity (Kansei). In the first step of appearance design, the designer embodies the shape image from concepts. In this stage, if 3D models can be easily built and corrected based on KANSEI, the process of embodying the shape image becomes easy. In addition, product design must also reflect customer needs. The objective of this study is therefore to develop a design system that can construct and analyze 3D car models based on terms expressing “Kanse”. In this study, these terms are defined as “Kansei words”.

Form Generation

Generative design system is a complex system that often focus on the technical and complex details thus away from building a system from the product designer’s thinking patterns. In addition, by focusing on the mechanism, the system is hard to construct and difficult to use for practical situation. Horizontal/vertical design thinking patterns are often used in product design practice, thus how designers make decision affect the generation reasoning. With the cognitive design researches on design thinking patterns, two research stages (experiment and implementation) are conducted and policy/generation rules are discovered during the experiment with 30 5-year design experts as focus group. An experimental system called thinking pattern-based generation system, a.l.a. ThinkGen is developed for testing the hypothesis.

This article focuses on applying the ethics of the product features during the students’ design education. Good/Bad design term is a conventional approach to discuss the ethical/unethical design values of the products. It is noted that different aspects of the product design such as visual information design, interface design, and appearance design have a vital role in judging the levels of ethics in the product. So the students of product design everywhere need to practice the term ethical/unethical design during their study because designers influence society more than they could imagine. This influence can be done by creating an attractive organized appearance and perfect functions that support the ethical brand’s image to the customers. The interviews and discussions were held as a research method with the students of product design in some institutions in addition to some design experts and customers to find out their opinions about the design values that achieve the ethical dimensions in the product design. They can end up with products that carry ethical values in their design. The final article’s results are in the descending order of the different design values according to their importance in emphasizing the ethical aspects of the products, in addition to a checklist including some important questions that can help the designers to be more aware of ethics’ considerations in the product design because ethics is a process of learning, not a process of obedience, and to highlighting the term of ethical designer which in turn reflects on the ethics of customers and societies.

Abstract This paper gives an overview of a collaborative design system (CDS) for electromechanical products. To reduce design costs and to manufacture high-quality products, it is well known that concurrent engineering (CE) is a very efficient approach. Three-dimensional (3D) CAD system and engineering database system are essential components of CE. The CDS is an environment to realize CE. By creating 3D models in a computer and performing some simulations such as mechanical, electronic, software simulation and integrated simulations, it is possible to estimate functions, assemblability, manufacturability and so on, before making prototype models. In this paper, we outline the CDS and mainly discuss the total information management system (TIMS) which makes an important role of the CDS. This paper describes the implementation experience of some functions of the TIMS.

Abstract Based on knowledge representation in product design, we propose a knowledge model of the product design process based on graphical semantic perception. The ontology semantic of the product is analyzed together with the product design process knowledge. Then the basic element model for knowledge representation of the product design process is built. With the concepts of the extension origin point basic element and extension vector thus defined, knowledge representation, consisting of growth, convergence and optimization is realized. On this basis, the model for case base clustering based on graphical semantics is built. Feasibility verification is performed with the case of appearance design of a machine tool. The highlight of the proposed method lies in the combination of the formalized and quantitative approach for product appearance design.

Abstract Rapid shape creation and visualization of solid models remains a tedious task despite advances in the field of Computer Aided Design (CAD)/Solid Modeling. CAD systems require a significant level of detail, such as vertices, edges, and faces to be specified by the user, even before the simplest of shapes can be created and viewed. In addition, most CAD systems have an essentially 2D interface for designing artifacts. This makes artifact visualization, for example by interactive rotation, difficult since all manipulations have be achieved by 2D translation of the mouse or by typing in the required angles of rotation. The limited visualization capability and the requirement to create shapes through the specification of low level entities is especially cumbersome in the concept shape design stage. This paper describes the Conceptual Virtual Design System, COVIRDS, a tool for product concept design. COVIRDS provides an intuitive voice and hand input-based interface for modeling of products using a ‘construction’ approach. Product shape models are created by ‘attaching’ simpler parametrically defined ‘Shape Elements’ to other elements to create more complex models. Voice commands are used to instantiate shape elements and change their parameters, for example, the width, length and height of a block element. 3D hand input is used for positioning shape elements during element attachment. The voice and hand input-based interface together with a stereoscopic visual display facilitates rapid creation and visualization of concept shape models.

Current product design methodologies do not typically address the creation of inclusive products (products that meet the needs of persons with and without disabilities). In this paper, empathic design principles and modular product design strategies are explored as part of a novel approach to inclusive design. The use of disability simulation as a data collection methodology both increases the safety and ease by which customer needs can be gathered and gives designers an empathic design experience with the products they develop. A disability simulation suit is designed to support empathic gathering of customer needs. The suit is subjected to validation trials to determine how accurately it mimics the physical and perceptual behaviors of persons with disabilities in users of the suit. Initial results show that the disability simulation suit provides a valid empathic design experience that yields similar customer needs and reduced dexterity as persons with disabilities.
