Designing a new product can be a challenging task particularly for a novice designer. This paper explores the application of TRIZ to assist a designer in performing this task within a descriptive design framework. The descriptive design framework permits the designer to track his ideas throughout the design process. The ‘technical contradiction matrix’ of TRIZ is integrated into this framework to allow it to provide support to designers. This contradiction matrix is adapted to enable designers to assign their levels of belief or preference to contradicting features to solve design problems. This preference assignment allows more emphasis to be placed on the critical features of a design problem. The proposed TRIZ-based system was tried out on a novice designer in a case study to design a scheme to support concrete filling between beams.

The orthosis is considered a class 1 medical device which often originates from a nonstructured development process. As these devices are mainly developed by small- and medium-sized enterprises, with no standard research method, the result can be an unadapted device which may not respond to the user’s needs and which in the short term may be abandoned. One way to solve this problem is to define and apply standard rules and procedures throughout the development/design process. Although methodologies may solve the “empiricism” in orthosis design problems, these design strategies are not applied during orthosis development due to the particularities of this field and the difficulties in linking the required knowledge and the actors that may be present during the orthosis development. The objective of this work is to develop a methodology to structure the orthosis design process that takes into account both the device life cycle and the different stakeholders involved in the design process. A case study was used to validate the proposed methodology. It was applied to the development of an orthosis to treat a specific postural disorder called camptocormia, also known as bent spine syndrome. This disorder is characterized by the anteroflexion of the trunk and especially affects elderly people. Contrary to scoliosis, the characteristics of camptocormia are not permanent, which means that the patient is able to straighten his posture. A postural brace is used to treat this disorder which enables the patient to redress and maintain the correct upright posture of the trunk.

Students learning design engineering at times need a good example of procedure for novel design engineering. The systematic heuristic-strategic use of a theory to guide the design process – Engineering Design Science – and the methodical design process followed in this case study is only necessary in limited situations. The full procedure should be learned, such that the studentcan select appropriate parts for other applications.This case example is presented to show application of the recommended method, and the expected scope of the output, with emphasis on the stages of conceptualizing. The case follows a novel design problem of a gangway for ship-shore transfer for the Caravan Stage Barge.

Cross-disciplinary technologies are noticeable phenomena in modern products, as found in renewable energy and electric vehicle industries. However, current conceptual design tools have been limited to respond these cross-disciplinary technology products. One of remarkable characteristics in this technology change is transforming an existing product with multiple cross-disciplinary technologies. This paper presents a new product design paradigm, called Transformative Product Design (TPD), to respond this phenomenon. In TPD, transformation is a design process to produce a new product (i.e., transformative product) from a base product by adding and/or converting functions/features with reference products or technologies. To accomplish the transformation process, this paper develops a new Functional Concept-based Detection method. Also, the proposed functional concept-based detection method is described with a case study in the context of transformative product design process.

Problem discovery is messy. It involves many mistakes, which may be regarded as a failure to address a design problem correctly. Mistakes, however, are inevitable, and misunderstanding the problems we are working on is the natural, default state of affairs. Only through engaging in a series of mistakes can we learn important things about our design problems. This study provides a case study in Many-Objective Visual Analytics (MOVA), as applied to the problem of problem discovery. It demonstrates the process of continually correcting and improving a problem formulation while visualizing its optimization results. This process produces a new, clearer understanding of the problem and puts the designer in a position to proceed with more-detailed design decisions.

Buildings are significant contributors to energy-related sustainability challenges and a sustainable future. Practice shows—that the traditional building design process is becoming ineffective and will no longer be able to meet the determined requirements and standards of low energy architecture. The aim of this research is to introduce and validate the newly developed technology of building design concept, which integrates Quality Function Deployment (QFD) and Axiomatic Design (AD) methods. The proposed technology eliminates the traditional building design problems, ensures a smooth Integrated Building Design (IBD) process and matches the needs of the customer and the whole building design team. The new technology also provides a quicker and more effective way to find a sustainable and customer-orientated solution. Validation of the technology on the case study has shown that the energy functionality of the building proved to be superior to buildings, created during traditional building design process.

AbstractAlgorithm-based optimization is widely applied in many fields like industrial production, resulting in state-of-the-art workflows in the production process optimization. This project takes the cultural lag of conventional industrial architecture design as a motivation to investigate the implementation of algorithm-based optimization into traditional design processes. We argue that an enhanced way of architectural decision-making is possible. Current approaches use a translation of the whole design problem into a single, overly complicated optimization system. Contrary to that, this paper presents a novel workflow that defines precise design steps and applies optimizations only if suitable. Furthermore, this method can generate relevant results for factory planning design problems with contradicting factors, making it a promising approach for the complex challenges of i.e. resource-efficient building.

Knowledge management has recently become the focus of public attention in business and engineering. Because knowledge acquisition is situated in the upstream of knowledge management, capturing knowledge is an important step for enterprises to achieve successful knowledge management. We focus on how engineers solve their design problems under given design contexts and propose a novel model and methods to capture knowledge from engineering design processes. Our goal is to acquire know-how knowledge without disrupting the normal design process. A three-layer design process model is introduced to represent generic design processes, and a grammar and extended dynamic programming (GEDP) method is developed based on the process model. GEDP adopts the grammar approach and EDP to automatically identify meaningful clusters, called operations, from primitive design events. Our approach is evaluated through a case study of designing a double-reduction gear system.

Garment Industry is one of the industries that have dumped a large amount of wasted fabric at least 30-40 kg / month. Wasted fabrics are caused by the process of sewing, hydraulic pumping, and flaws on fabric. Those wastes were not being used for any further utilization. The current work investigated the use of Upcycling, a process to converse waste material to become a new product with higher quality and environmentally friendly value, as a conceptual model in the design process and examined its value for Upcycling product design by looking at a case study project. The concept from the Upcycling framework study was chosen for the investigation in order to evaluate a case study: a wasted fabric lamp. The findings suggest that Upcycling was helpful for improving and developing a wasted fabric lamp throughout the design process: including idea development, decision making, and implementation. Based on the evaluation of 3 design experts, it was found that a wasted fabric lamp is appropriate for using new materials or raw materials that do not cause problems for the environment.

While most engineering schools substantially agree on the general form of the design process that should be used to address engineering design problems, surprisingly little is known about the actual practical effectiveness of many recommended techniques. In this paper and presentation, we review some of the recent evidence concerning the effectiveness of several well- known practices related to ideation - i.e., generating alternative potential solutions to a design problem.
