Author supplied from the article: ABSTRACT Increasing global competition in manufacturing technology puts pressure on lead times for product design and production engineering. By the application of effective methods for systems engineering (engineering design), the development risks can be addressed in a structured manner to minimise chances of delay and guarantee timely market introduction. Concurrent design has proven to be effective in markets for high tech systems; the product and its manufacturing means are simultaneously developed starting at the product definition. Unfortunately, not many systems engineering methodologies do support development well in the early stage of the project where proof of concept is still under investigation. The number of practically applicable tools in this stage is even worse. Industry could use a systems engineering method that combines a structured risk approach, concurrent development, and especially enables application in the early stage of product and equipment design. The belief is that Axiomatic Design can provide with a solid foundation for this need. This paper proposes a ‘Constituent Roadmap of Product Design’, based on the axiomatic design methodology. It offers easy access to a broad range of users, experienced and inexperienced. First, it has the ability to evaluate if knowledge application to a design is relevant and complete. Secondly, it offers more detail within the satisfaction interval of the independence axiom. The constituent roadmap is based on recent work that discloses an analysis on information in axiomatic design. The analysis enables better differentiation on project progression in the conceptual stage of design. The constituent roadmap integrates axiomatic design and the methods that harmonise with it. Hence, it does not jeopardise the effectiveness of the methodology. An important feature is the check matrix, a low threshold interface that unlocks the methodology to a larger audience.

circular economy as a system change is gaining more attention, reusing materials and products is part of this, but an effective method for repurposing seems to be missing. Repurpose is a strategy which uses a discarded product or its parts in a new product with a different function. Literature on specific design methods for 'repurposing’ is limited and current design methods do not specifically address repurpose driven design. This paper aims to contribute to the literature on repurpose as a circularity strategy by evaluating repurpose driven design processes which are deployed in practice and evaluate to what extend existing design methods are suited for repurpose driven design. Building on a multiple case study two main design approaches are identified. First, a goal-oriented approach in which a client commissions the design studio. Second, a resource-oriented approach in which a discarded product or its components is the starting point of a design process initiated by the designers. Although both approaches follow a more or less standard design process, each intervenes with repurpose specific input at different phases in the design process, depending on the role of the designer. Results show that in order to be able to deal with the inconsistencies of discarded products, specific repurpose-related tools are required for an efficient and effective repurpose driven design process. Future research should address these issues in order to develop comprehensive and practical tools that accommodate the two repurpose driven design approaches.
Hoogwaardig afvalhout van bewoners, bouwbedrijven en meubelmakers blijft momenteel ongebruikt omdat het te arbeidsintensief is om grote hoeveelheden ongelijke stukken hout van verschillende afmetingen en soorten te verwerken. Waardevol hout wordt waardeloos afval, tegen de principes van de circulaire economie in. In CW.Code werken Powerhouse Company, Bureau HUNC en Vrijpaleis samen met de HvA om te onderzoeken hoe een toegankelijke ontwerptool te ontwikkelen om upcycling en waardecreatie van afvalhout te faciliteren. In andere projecten hebben HvA en partners verschillende objecten gemaakt van afvalhout: een stoel, een receptiebalie, kleine meubels en objecten voor de openbare ruimte, vervaardigd met industriële robots. Deze objecten zijn 3D gemodelleerd met behulp van specifieke algoritmen, in de algemeen gebruikte ontwerpsoftware Rhino en Grasshopper. De projectpartners willen nu onderzoeken hoe deze algoritmen via een toegankelijke tool bruikbaar te maken voor creatieve praktijken. Deze tool integreert generatieve ontwerpalgoritmen en regelsets die rekening houden met beschikbaar afvalhout, en de ecologische, financiële en sociale impact van resulterende ontwerpen evalueren. De belangrijkste ontwerpparameters kunnen worden gemanipuleerd door ontwerpers en/of eindgebruikers, waardoor het een waardevol hulpmiddel wordt voor het co-creëren van circulaire toepassingen voor afvalhout. Dit onderzoek wordt uitgevoerd door HvA Digital Production Research Group, met bovengenoemde partners. HUNC heeft ervaring met stadsontwikkeling waarbij gebruik wordt gemaakt van lokaal gekapt afvalhout. Vrijpaleis biedt toegang tot een actieve, lokale community van makers met een sterke band met buurtbewoners. Powerhouse Company heeft ervaring in het ontwerpen met hout in de bouw. Alle drie kunnen profiteren van slimmere circulaire ontwerptools, waarbij beschikbaar materiaal, productiebeperkingen en impactevaluatie worden geïntegreerd. De tool wordt ontwikkeld en getest voor twee designcases: een binnenmeubelobject en een buitengevelelement. Bevindingen hiervan zullen leidend zijn bij de ontwikkeling van de tool. Na afronding van het project is een bètaversie gereed voor validatie door ontwerpers, bewonerscollectieven en onderzoek/onderwijs van de HvA.
Low back pain is the leading cause of disability worldwide and a significant contributor to work incapacity. Although effective therapeutic options are scarce, exercises supervised by a physiotherapist have shown to be effective. However, the effects found in research studies tend to be small, likely due to the heterogeneous nature of patients' complaints and movement limitations. Personalized treatment is necessary as a 'one-size-fits-all' approach is not sufficient. High-tech solutions consisting of motions sensors supported by artificial intelligence will facilitate physiotherapists to achieve this goal. To date, physiotherapists use questionnaires and physical examinations, which provide subjective results and therefore limited support for treatment decisions. Objective measurement data obtained by motion sensors can help to determine abnormal movement patterns. This information may be crucial in evaluating the prognosis and designing the physiotherapy treatment plan. The proposed study is a small cohort study (n=30) that involves low back pain patients visiting a physiotherapist and performing simple movement tasks such as walking and repeated forward bending. The movements will be recorded using sensors that estimate orientation from accelerations, angular velocities and magnetometer data. Participants complete questionnaires about their pain and functioning before and after treatment. Artificial analysis techniques will be used to link the sensor and questionnaire data to identify clinically relevant subgroups based on movement patterns, and to determine if there are differences in prognosis between these subgroups that serve as a starting point of personalized treatments. This pilot study aims to investigate the potential benefits of using motion sensors to personalize the treatment of low back pain. It serves as a foundation for future research into the use of motion sensors in the treatment of low back pain and other musculoskeletal or neurological movement disorders.
In the road transportation sector, CO2 emission target is set to reduce by at least 45% by 2030 as per the European Green Deal. Heavy Duty Vehicles contribute almost quarter of greenhouse gas emissions from road transport in Europe and drive majorly on fossil fuels. New emission restrictions creates a need for transition towards reduced emission targets. Also, increasing number of emission free zones within Europe, give rise to the need of hybridization within the truck and trailer community. Currently, in majority of the cases the trailer units do not possess any kind of drivetrain to support the truck. Trailers carry high loads, such that while accelerating, high power is needed. On the other hand, while braking the kinetic energy is lost, which otherwise could be recaptured. Thus, having a trailer with electric powertrain can support the truck during traction and can charge the battery during braking, helping in reducing the emissions and fuel consumption. Using the King-pin, the amount of support required by trailer can be determined, making it an independent trailer, thus requiring no modification on the truck. Given the heavy-duty environment in which the King-pin operates, the measurement design around it should be robust, compact and measure forces within certain accuracy level. Moreover, modification done to the King-pin is not apricated. These are also the challenges faced by V-Tron, a leading company in the field of services in mobility domain. The goal of this project is to design a smart King-pin, which is robust, compact and provides force component measurement within certain accuracy, to the independent e-trailer, without taking input from truck, and investigate the energy management system of the independent e-trailer to explore the charging options. As a result, this can help reduce the emissions and fuel consumption.
