In this exploration of the human battery interface, the way in which battery information and notifications effect interaction are analyzed through two small scale studies and a design proposal which is then user tested. With the first study, an attempt is made to gauge user’s feelings toward the current battery information display on their smartphones through a brief online questionnaire. Participants who were selected for further study installed battery monitoring software on their devices and shared the resulting data. This data was then analyzed and some usage patterns were extrapolated. After surveying current market solutions and research in the field, design opportunities were explored and a final design proposal was created and tested with possibilities for further applications being discussed.

This thesis project identifies an issue of limited interaction options with cell phones and considers it to be a design opening and opportunity, rather than a problem. The design opportunity presented in this work is for shaping of future cell phone interactions by allowing users to design their own cell phones. To explore this provocative yet complex design opportunity a programmatic design research approach is used. The design program in this thesis is referred to as the ‘Design-It-Together cell phone’, or the DIT cell phone, design program and can be described as a design research effort into how users working together to design and make their own cell phones could offer a new set of perspectives and possibilities in shaping future interaction options with cell phones in contrast to an industry lead cell phone design and development process. Furthermore, the motivation for this thesis is not problem-based but rather exploratory, where the intention is not to build an ideal phone but rather to explore the opportunities and challenges faced by the design program, and what that can mean for shaping the future of cell phone interactions. A comprehensive exploration of this design space was done in nine main explorations or nine main experiments. Each experiment was formulated to challenge a perspective of the design program. The results of the explorations generated a repertoire of examples relating to understanding the current situations and predictions for future possibilities for cell phone interactions. Interpretation of the design program was done by analyzing this repertoire of examples from the perspective of n nine specified dimensions of the design program. The dimensions acted as a guide in thinking about possible futures of cell phone interactions within the design space of the program. Interpretation of the design program in this way allowed for comprehensive scenarios to be created of what the future of cell phone interactions could be like, as well as gaps and bigger picture impacts of the design program. The overall results and contribution of this work adhered to what is expected from a programmatic design research approach and is stated here as knowledge generated from explorations and interpretation of the DIT cell phone design program, based on the generated repertoire of examples, which helps shape possible futures for cell phone interactions.

Design Research 2024 folgt als Fortsetzung dem ersten Band Design Research 2020, der erneut als eigenständiger Sammelband mit acht Beiträgen Einblicke in aktuelle Promotionsvorhaben der Professur für Technisches Design der TU Dresden bietet. Dabei scheinen die inzwischen gestärkten Verknüpfung weiterhin technologieorientierter Designforschungsthemen mit übergreifenden Nachhaltigkeitserfordernissen (Sustainability) und dafür notwendigerweise zu gestaltenden Übergangsprozessen (Transition) nun deutlicher auf. Die Designforschung hat an der TU Dresden eine lange Tradition. Erste Forschungs- und Promotionsvorhaben fanden bereits ab den späten 1960er Jahren unter Rudi Högner statt. Schon damals wurde Fragestellungen zum Design in technisch komplexen Kontexten und Multi-Stakeholder-Konstellationen in empirischen und interdisziplinär geprägten Forschungsvorhaben nachgegangen. Im Kontext der dann als Arbeitsumweltdesign bezeichneten Ausrichtung der Designforschung an der TU Dresden folgten weitere Dissertationen in den 1980er Jahren unter Betreuung von Johannes Uhlmann.

Indiana University-Purdue University Indianapolis (IUPUI) / Crashworthiness design is gaining more importance in the automotive industry due to high competition and tight safety norms. Further there is a need for light weight structures in the automotive design. Structural optimization in last two decades have been widely explored to improve existing designs or conceive new designs with better crashworthiness and reduced mass. Although many gradient based and heuristic methods for topology and topometry based crashworthiness design are available these days, most of them result in stiff structures that are suitable only for a set of vehicle components in which maximizing the energy absorption or minimizing the intrusion is the main concern. However, there are some other components in a vehicle structure that should have characteristics of both stiffness and flexibility. Moreover, the load paths within the structure and potential buckle modes also play an important role in efficient functioning of such components. For example, the front bumper, side frame rails, steering column, and occupant protection devices like the knee bolster should all exhibit controlled deformation and collapse behavior. This investigation introduces a methodology to design dynamically crushed thin-walled tubular structures for crashworthiness applications. Due to their low cost, high energy absorption efficiency, and capacity to withstand long strokes, thin-walled tubular structures are extensively used in the automotive industry. Tubular structures subjected to impact loading may undergo three modes of deformation: progressive crushing/buckling, dynamic plastic buckling, and global bending or Euler-type buckling. Of these, progressive buckling is the most desirable mode of collapse because it leads to a desirable deformation characteristic, low peak reaction force, and higher energy absorption efficiency. Progressive buckling is generally observed under pure axial loading; however, during an actual crash event, tubular structures are often subjected to oblique impact loads in which Euler-type buckling is the dominating mode of deformation. This undesired behavior severely reduces the energy absorption capability of the tubular structure. The design methodology presented in this paper relies on the ability of a compliant mechanism to transfer displacement and/or force from an input to desired output port locations. The suitable output port locations are utilized to enforce desired buckle zones, mitigating the natural Euler-type buckling effect. The problem addressed in this investigation is to find the thickness distribution of a thin-walled structure and the output port locations that maximizes the energy absorption while maintaining the peak reaction force at a prescribed limit. The underlying design for thickness distribution follows a uniform mutual potential energy density under a dynamic impact event. Nonlinear explicit finite element code LS-DYNA is used to simulate tubular structures under crash loading. Biologically inspired hybrid cellular automaton (HCA) method is used to drive the design process. Results are demonstrated on long straight and S-rail tubes subject to oblique loading, achieving progressive crushing in most cases.

Fear is an intrinsic human emotion, which produces with variable intensity a bodily reaction as a response to a stimuli. It is considered one of the basic human emotions, and it is universal of all animal species. Despite its subjective quality, fear has gained a rather negativistic stereotype that this research intends to debate and readdress, proposing that “negative fear” is part of an evolutionary transition cultivated by social and cultural constructs. This thesis will analyze the context in which fear operates, employing experience design methodologies and design research to reevaluate the role of fear in the contemporary settings of our societies to prove its connection to imagination, transhumanism and the production of empathy. After a brief historical perspective to situate this thesis in the contemporary framework of experience design, this research will investigate fear as prolific tool for the production of imagination, derived from its aesthetic connection to wonder and pleasure. This particular connection between fear to wonder was investigated among others by Charles Darwin, who also promoted the functionality of fear as the key to animal survival. The complex mechanism in which fear engages us will lead to the production of design prototypes that look at the animal kingdom and several other species’ talents in the detection and implementation of fear as a tool to survive. Here, the potential of our species to further evolve through the use of design will open a discussion on transhumanism and the future of humanity. The last section speculates a counterfactual conditional statement of how our humanity would operate, if emotional identities were reevaluated. In particular, the emotion of fear will be reevaluated for its unpleasant characteristics, from the bodily sensations to the mental postliminary conditions, to understand why certain human behaviors are still exercised, when the physiological effects are universally acknowledged as distasteful. By interpreting the physiological impact of fear, this research will continue its argument towards empathy, questioning what it truly means to ‘stand in someone’s else shoes’, specifically when fear is practiced. Empathy, as a pilaster in the mission statement of many contemporary disciplines, has surfaced in this research as viral phenomenon, which little has to do with truly ‘empathizing’. Here, it investigates how empathy can be experienced when fear is in play: if sharing fear as the bodily experience of someone else can lead to the production of authentic empathy, then humans have a chance to reevaluate its application in the contemporary global topics of war and diplomacy, domestic and public violence, or bullying to name a few. This research ultimately establishes a new perspective on the role of emotions in our societies, and creates a connection between design and the experience of intangibles, producing a view of the intrinsic systems of our being as ones deemed of value in the ambitious evolution of our species. / <p>The full thesis contains copyrighted material which has been removed in the published version.</p>

This study focuses on challenges and prospects of the teaching of the Doppler Effect to grade 12 learners. The challenges of teaching the Doppler Effect were established and these findings influenced the development of activities. These activities were tested, refined and re-tested in an iterative cycle and finally provided prospects on teaching the Doppler Effect. Educational Design Research (EDR) was used to bridge theory and practice in education. This study was done in the Vhembe district in the Limpopo province. In the first cycle, questionnaires and interviews with 32 teachers and a subject advisor were used to establish the baseline with regards to the challenges of teaching the Doppler Effect. After the analysis of the data which forms the first cycle of EDR, the content and methodological problems faced by teachers when teaching the Doppler Effect were revealed. In the second cycle of the EDR, learning activities were developed that was informed by the analysis and tried out in 2 schools by learners and their teachers. Completed activity sheets were marked and the results were used to determine if there were a correlation between the activity sheets and the written test. Problems were documented and changes to the activities were again made and tried out in 10 schools by 216 learners with the help of 10 teachers. The data collected from the learners` work sheets were analysed. Pearson`s product moment correlation has shown that there is a statistically significant relationship (r = 0.65; p < 0.01) that exists between these design-research activities and solving of problems on the Doppler Effect. An instructional manual was developed comprising of the final activities. This was distributed amongst the district officials and teachers to assist them in the teaching of the Doppler Effect in the Vhembe district. / Physics / M.Sc.(Mathematics, Science and Technology Education)
