Abstract Most of the front loaders are compact structures that do not allow loading at greater heights. On the Polish and foreign market, there was a need to develop a front loader design that would allow to increase the loading height. As a result, the front loader was designed a front loader with the possibility of extending the arms for the Kubota M5 agricultural tractor. The system enables unloading and loading of cubes, straw and hay bales on higher piles. Before starting the design process, the available front loader solutions were analyzed and on this basis, three concepts of design solutions were proposed. These concepts were scored on the basis of the adopted criteria and the one with the highest number of points was selected. For the selected concept, strength analytical calculations and verification calculations using the FEM method were performed. The developed loader is innovative compared to other available designs and has a good chance of implementation.

The article presents the design process of the gerotor pump body made of plastic. As the shape of the projected body a simple prism with a square base was adopted. That body shape is called the basic. It consists of three parts: front, middle and back body, which are connected by a screw joint. This shape was subject to strength analysis, using the FEM method. As a result of these analysis, the place and nature of the stress and deformation of the basic body shape was determined. It was established that the body is deformed in both axial ie. along the pump shaft axis, and radial directions, ie. perpendicular to the axis of the shaft. There have been made modifications to the basic shape of the body in order to reduce the stress and deformation. As a result of these modifications, the modified body shape was obtained, which was then subjected to strength analysis by FEM method. It was found that the modifications resulted in reduction of the stress and deformation. Reducing the stress values, enables loading of pump body with higher operating pressures. Reducing the deformation of the body leads to a reduction in axial and radial clearances in the pump and enables achieving higher efficiency.

AbstractA design problem with deficient information is generally described as wicked or ill-defined. The information insufficiency leaves designers with loose settings, free environments, and a lack of strict boundaries, which provides them with more opportunities to facilitate innovation. Therefore, to capture the opportunity behind the uncertainty of a design problem, this study models an innovative design as a composite solving process, where the problem is clarified and resolved from fuzziness to satisfying solutions by interplay among design problems, knowledge, and solutions. Additionally, a triple-helix structured model for the innovative product design process is proposed based on the co-evolution of the problem, solution, and knowledge spaces, to provide designers with a distinct design strategy and method for innovative design. The three spaces interact and co-evolve through iterative mappings, including problem structuring, knowledge expansion, and solution generation. The mappings carry the information processing and decision-making activities of the design, and create the path to satisfying solutions. Finally, a case study of a reactor coolant flow distribution device is presented to demonstrate the practicability of this model and the method for innovative product design.

Early Phases

Various architectures exposing certain phases of the design process have been developed. A closer analysis of the presented timelines is leading more to postpone the design solution rather than advancing it in the early phases. This paper advances a new architecture for the design process with the main emphasize on the product functional design, based on functional-constructive knowledge stored in databases, and on the principle of selecting design solutions in an incipient phase and developing them during the further design process stages.

<p>Knostrop Footbridge was designed and constructed as part of the Leeds Flood Alleviation Scheme. The project’s principle objective was to provide new walking and cycling routes along the River Aire, as well as creating a landmark gateway to the city. Given the intended purpose, budget, programme, and site constraints, a list of key aspirations was developed:</p><ul><li><p>Creation of a slender, flowing structure which “floats” over the water and encourages local use and interest.</p></li><li><p>Simplified construction through off-site fabrication and streamlined installation.</p></li><li><p>Mirroring the alignment of the soon to be constructed Knostrop Weir and utilising the weir walls for sub structure support, all whilst accommodating the construction lag between the weir and the bridge.</p></li><li><p>A durable, low maintenance structure is essential with the difficult access constraints of the weir.</p></li></ul><p>Achieving the above in combination required an innovative approach. Numerous potential solutions were developed, experimented with, and analysed, prior to finalising the design.</p><p>This iterative process allowed the bridge to develop into a unique, innovative, and recognisable design, and one which exceeded expectations to efficiently fulfil its purpose with minimal anticipated lifetime maintenance.</p><p>This paper presents the innovative design solutions adopted in overcoming the various challenges and achieving the design aspirations.</p>

Matrix Case

With the rise in popularity of additive manufacturing (AM), relevant design methodologies have become necessary for designers to reap the full benefits from this technology. TRIZ is a problem-solving tool developed to assist with innovative and creative solutions. This paper aims to create a new TRIZ matrix specifically developed for designers using additive manufacturing. The TRIZ matrix offers designers general innovative design solutions to improve specific features of a design while not sacrificing the effectiveness of other features. The proposed matrix can help effective design decision making for additive manufacturing in an early design process as well as a redesign process. Also, a design for additive manufacturing (DfAM) worksheet is provided to enable users to easily find specific design solutions for certain additive manufacturing techniques based on the general solutions derived by the TRIZ matrix. To illustrate the potential of this AM specific TRIZ matrix, case studies are presented.

Beta Test

This article presents study that shows beta testing shapes software to the users’ hands so the product will fit the marketplace. MoldWizard is intended to reduce the time necessary to design complex mold tooling, such as this mold used to manufacture the plastic housings for high-quality nail guns. Depending on the complexity of a mold and its eventual use, the design process can require as many as 50 different steps, including tasks such as importing and cleaning up the CAD model of the part, adjusting its size for shrinkage, separating the core and cavity, generating mold bases, and adding sliders, inserts, and other standard components. Minco Tool & Mold uses Unigraphics to design molds like the one shown in the article for an automobile hubcap. Minco participated in the MoldWizard beta test program. A news group at the website let the test users communicate directly with each other. When beta testers had questions about how to use the program, they posted them in the news group and other testers would respond.

Tagging systems design is often neglected despite the fact that most system designers agree on the importance of tagging. They are viewed as part of a larger system which receives most of the attention. There is no agreed method when it comes to either analyzing existing tagging systems or designing new ones. There is a need to establish a well-structured design process that can be followed to create tagging systems with a purpose. This chapter uses practical inquiry methodology to generate a general framework that can be applied to analyze tagging systems and proceeds to suggest a design process that can be followed to create new tagging systems. Existing user behavior while tagging is the main guide for the methodology.

Ubiquitous Presence

Design has been described by Bruno Latour as the missing masses, and tellingly as “nowhere to be said and everywhere to be felt” (2005: 73). Traditionally, not only objects, but design’s presence in general has gone largely unnoticed by the public, but that is changing, due, in considerable part, to the ubiquitous presence of computing technology. Design, as representative of unnoticed and neutral objects, is no longer feasible, but design, as a participative presence in the lives of its users, is fast gaining ground in our complex society. Designers are no longer fully in control of the design process, meaning design practice, and as a result design education must change to adapt to the increasing pace at which different social groups are evolving new ways of communicating and living.
