Product design in the context of the social needs in less industrialised economies

This thesis is related to the subject of technical innovation, specifically to the activity of design in microenterprises operating in less industrialised economies. Design here is understood as a process, which is not the sole domain of formally trained categories such as engineers, architects or industrial designers. The 'professional boundary' discussion in this investigation is perceived as secondary as, in this context, products are designed, copied or adapted by workers, entrepreneurs themselves, or directly by the poor community. Design capacity at this level is considered to be important both in relation to the conception of capital and consumer goods and to the building up of technical knowledge. Although professional design emerged in Latin America little over three decades ago, this activity has remained marginalised throughout industry. Design activity tends to be concentrated in some product categories in the formalised industrial sector. For microenterprises operating informally, industrial design appears to be unknown. The existing literature pays little attention to 'informal design' capacity. Other areas of knowledge, such as development economies, recognise the importance of microenterprises and technological capability but neglect the potential role of industrial design in small manufacturing units. The management literature, though it focuses on technical innovation and design, has also paid little attention to 'informal design'. In less industrialised economies this neglect is felt by the lack of programmes specifically tailored to create or stimulate 'informal design'. There is a need for recognition of 'informal design' capacity and for the implementation of programmes which specifically target design as a central activity in the manufacturing firm, independent of their size and technological capability. Addressing 'design by the poor for the poor', requires a down-to-earth approach.

Practice based learning approaches in collaborative design and engineering education:a case study investigation into the benefits of a crossdisciplinary practice based learning strategy

This study explores the ongoing pedagogical development of a number of undergraduate design and engineering programmes in the United Kingdom. Observations and data have been collected over several cohorts to bring a valuable perspective to the approaches piloted across two similar university departments while trialling a number of innovative learning strategies. In addition to the concurrent institutional studies the work explores curriculum design that applies the principles of Co-Design, multidisciplinary and trans disciplinary learning, with both engineering and product design students working alongside each other through a practical problem solving learning approach known as the CDIO learning initiative (Conceive, Design Implement and Operate) [1]. The study builds on previous work presented at the 2010 EPDE conference: The Effect of Personality on the Design Team: Lessons from Industry for Design Education [2]. The subsequent work presented in this paper applies the findings to mixed design and engineering team based learning, building on the insight gained through a number of industrial process case studies carried out in current design practice. Developments in delivery also aligning the CDIO principles of learning through doing into a practice based, collaborative learning experience and include elements of the TRIZ creative problem solving technique [3]. The paper will outline case studies involving a number of mixed engineering and design student projects that highlight the CDIO principles, combined with an external industrial design brief. It will compare and contrast the learning experience with that of a KTP derived student project, to examine an industry based model for student projects. In addition key areas of best practice will be presented, and student work from each mode will be discussed at the conference.

Trandisciplinarity and Design: Comparative Review and Synthesis for the Design Process

Transdisciplinarity gained importance in the 1970s, with the initial signs of weakness of both multi- and interdisciplinary approaches. This weakness was felt due to the increased complexity in the social and technological landscapes. Generally, discussion over the transdisciplinary topic is centred in social and health sciences. Therefore, the major challenge in this research is to adapt design research to the emerging transdisciplinary discussion. Based on a comparative and critical review of several engineering and design models for the design process, we advocate the importance of collaboration and conceptualisation for these disciplines. Therefore, a transdisciplinary and conceptual cooperation between engineering and industrial design disciplines is considered as decisive to create breakthroughs. Furthermore, a synthesis is proposed, in order to foster the cooperation between engineering and industrial design.

Reactive and proactive approaches for introspective CBR

This work investigates applying introspective reasoning to improve the performance of Case-Based Reasoning (CBR) systems, in both reactive and proactive fashion, by guiding learning to improve how a CBR system applies its cases and by identifying possible future system deficiencies. First we present our reactive approach, a new introspective reasoning model which enables CBR systems to autonomously learn to improve multiple facets of their reasoning processes in response to poor quality solutions. We illustrate our model’s benefits with experimental results from tests in an industrial design application. Then as for our proactive approach, we introduce a novel method for identifying regions in a case-base where the system gives low confidence solutions to possible future problems. Experimentation is provided for Zoology and Robo-Soccer domains and we argue how encountered regions of dubiosity help us to analyze the case-bases of a given CBR system.

Kiinteäkerroskaasuttimen toiminnan teoreettinen tarkastelu ja puupellettien kaasutuskokeet myötävirtareaktorilla

Tämä työ on osa tutkimusprojektia, jonka tarkoituksena on kehittää uudentyyppinen kaasutustekniikkaan perustuva kiinteistöjen lämmitysjärjestelmä. Työ on tehty osaksi kirjallisuustutkimuksena käyttämällä hyödyksi alalla tehtyjä tutkimuksia ja kirjallisuutta. Kirjallisuustutkimuksen tavoitteena oli luoda yhtenäinen tietopaketti lämmitysjärjestelmän kehityksen tueksi. Työn kokeellisen osion tavoitteena oli tutkia lämmitysjärjestelmän kaasuttimen prototyypin toimintaa ja selvittää sen käyttöön liittyviä ongelmia. Kirjallisuusosiossa käsitellään kaasutuksen vaiheita: alkulämpeneminen ja kuivuminen, syttyminen, pyrolyysi sekä jäännöshiilen palaminen ja kaasutus. Varsinkin pyrolyysiprosessin tunteminen on merkittävää, kun halutaan parantaa biomassan poltto- ja kaasutusprosessien suunnittelua. Lisäksi kirjallisuusosiossa käsitellään kaasutuksessa syntyvän tuotekaasun ominaisuuksia: koostumus, lämpöarvo, tiheys ja palamisominaisuudet. Tuotekaasun ominaisuudet vaihtelevat suuresti kaasutusprosessista ja -olosuhteista sekä polttoaineesta riippuen. Tuotekaasun kohdalta käsitellään myös sen käyttökohteita. Perinteisesti kaasutuksen tuotekaasua käytetään lämmöntuotantoon, mutta tulevaisuuden haasteena on tuotekaasun käyttö kaasuturbiineissa sähköntuotantoon. Tuotekaasun käyttöä laajemmin rajoittaa sen sisältämät epäpuhtaudet. Tämän vuoksi kirjallisuusosiossa käsitellään myös tuotekaasun puhdistusmenetelmiä ja sen poltossa syntyvien päästöjen vähentämiskeinoja. Kokeellisessa osiossa suoritettiin puupellettien kaasutuskokeita TTKK:n Energia- ja prosessitekniikan laitoksen raskaaseen laboratorioon rakennetulla kaasutusreaktorilla. Kaasutuskokeiden avulla löydettiin kaasutusreaktorin toiminnan ongelmakohdat ja pystyttiin aloittamaan lämmitysjärjestelmän jatkokehitys.

Computing the persistent homology of range images with alpha shapes

Laser scanning is becoming an increasingly popular method for measuring 3D objects in industrial design. Laser scanners produce a cloud of 3D points. For CAD software to be able to use such data, however, this point cloud needs to be turned into a vector format. A popular way to do this is to triangulate the assumed surface of the point cloud using alpha shapes. Alpha shapes start from the convex hull of the point cloud and gradually refine it towards the true surface of the object. Often it is nontrivial to decide when to stop this refinement. One criterion for this is to do so when the homology of the object stops changing. This is known as the persistent homology of the object. The goal of this thesis is to develop a way to compute the homology of a given point cloud when processed with alpha shapes, and to infer from it when the persistent homology has been achieved. Practically, the computation of such a characteristic of the target might be applied to power line tower span analysis.
