Title: The influence of risk classification and community affiliation on the acceptance of user-innovated medical devices
Authors: Fiedler, Jakob; Schorn, André; Herstatt, Cornelius
Abstract: User innovation contributes significantly to societal advancement, particularly in developing novel products and services, offering substantial financial potential, and fostering the common good. This is particularly evident in medical science, where it addresses diverse needs and is often shared at minimal or no cost. However, the diffusion of user-innovated products remains limited and research on the perception of user-innovated products is rather scarce, reducing their potential contributions to the common good. This paper investigates end-users' perceptions of user innovation, a critical yet underexplored aspect of diffusion. Specifically, using a mixed-methods approach, we examine the influence of product risk classification and community development on the perception of user-innovated medical devices. This study combines qualitative research through semi-structured interviews (n=5) and quantitative research using a 2x3 (User Innovation vs. Producer Innovation; Product risk classification I, II, III) between-subject experiment (n=301). Our findings reveal that end-users evaluate user-innovated and traditionally-innovated products differently based on various criteria. User-innovated products are perceived as more pleasant and attractive, while traditionallyinnovated products are viewed as safer and of higher value. This effect is more pronounced for products with higher risk classifications. However, the perceived lower safety and value of user innovation products result in a reduced willingness to purchase among end-users. Additionally, we find that community-developed user-innovated products consistently outperform in all evaluation categories compared to "pure" user-innovated products.2023-01-01T00:00:00ZEcological lightweight design for sustainable composites: Need for application of frugal engineering principles

Title: Ecological lightweight design for sustainable composites: Need for application of frugal engineering principles
Authors: Achtelik, Timo; Tiwari, Rajnish
Abstract: Lightweight design is regarded as a technological approach to engineer products in a more energy and material efficient- and, therefore, resource-saving way. In this sense, high-tech multi-materials, also referred to as composites, have become very popular for many decades due to their adaptability of material characteristics as well as high specific mechanical properties. However, composites in particular have also challenging characteristics, for example in the end-of-life of a product, as they cannot be recirculated in a typical material stream, or can only be recycled to a very limited extent (also known as 'downcycling'). Alongside a common product lifecycle, we therefore describe challenges and constraints of ecological lightweight design and underpin the identified issues using semi-structured interviews with experts from the lightweight industry. We further approach the topic through the theoretical lens of frugal engineering, which critically evaluates and reduces the effective features and performances needed for an innovation thus resulting in more affordable and sustainable outcomes. Arguably, frugality might play a decisive role in ecological material transition as technology-driven innovation paradigms in search for the best material are substituted by more use case oriented engineering principles in search for the most suitable material.2022-01-01T00:00:00ZLes opportunités de la frugalité dans l'ère post-Corona

Title: Les opportunités de la frugalité dans l'ère post-Corona
Authors: Herstatt, Cornelius; Tiwari, Rajnish
Abstract: L'objectif de ce document de travail est double: Premièrement, nous évaluons l'impact probable de la crise Corona sur les choix économiques et sociétaux des personnes, notamment en ce qui concerne la simplicité volontaire. Deuxièmement, nous contextualisons l'impact de ces choix dans le domaine de la gestion de l'innovation. En adoptant une perspective normative-conceptuelle, nous cherchons à comprendre dans quelle mesure la frugalité, et entre autres les in-novations frugales, peuvent jouer un rôle dans une meilleure gestion des effets de la crise Corona et quelles implications en découlent pour les acteurs sociétaux concernés, en particulier pour les entreprises, les décideurs politiques et les consommateurs. En prenant note des discussions historiques sur le rôle de la frugalité en tant que "vertu", nous proposons que la quatrième renaissance de la frugalité, actuellement en cours, doit - et est sus-ceptible - d'émerger comme une mégatendance qui pourrait façonner une "ère" frugale aboutis-sant à "l'excellence verte abordable" comme paradigme d'innovation dominant. Pour réaliser ce potentiel, il est toutefois nécessaire de s'éloigner de l'accent unidimensionnel mis sur l'accessibili-té monétaire des solutions frugales. Il est nécessaire de développer une compréhension plus complète et multidimensionnelle de l'accessibilité financière qui vise à garantir l'accessibilité financière, sociétale, infrastructurelle et écologique des produits, services, technologies et mo-dèles commerciaux frugaux. Les innovateurs et entrepreneurs frugaux ne doivent pas se contenter de viser une "réduction significative des coûts" par rapport aux produits de substitution existants, mais plutôt viser à garantir une "accessibilité financière élevée" qui ouvrira de nouveaux horizons commerciaux grâce à des innovations de rupture et à l'excellence technologique. Ce changement de paradigme nécessite l'intervention de toutes les parties prenantes, y compris les décideurs politiques.2022-01-01T00:00:00ZFrugal sustainability: A new perspective to foster corporate sustainability

Title: Frugal sustainability: A new perspective to foster corporate sustainability
Authors: Achtelik, Timo; Herstatt, Cornelius; Tiwari, Rajnish
Abstract: Frugal innovations are increasingly considered in the context of sustainability and are seen to have promising potential for the realization of global sustainability goals. So far, the discourse has focused on the question of whether and how frugal innovations contribute to sustainable development without presenting concrete guidelines and principles. Through a systematic literature review guiding principles are therefore derived, conceptualized in the motivational context of emerging and industrialized economies and empirically illustrated using the example of Western automotive companies. The principles can be used to further substantiate the link between frugal innovations and corporate sustainability as well as to use them for the development of green(er) innovation.2022-01-01T00:00:00Z
