Managing Circular Business Model Uncertainties with Future Adaptive Design

Designing products that can adapt to changes over time is crucial for managing product-related business risks in circular business models. However, there is limited circular economy research on how product adaptivity can contribute to more circular products and business models, especially in the early phases of business development and design. To address this research gap, this conceptual paper builds on the adaptable design concept and incorporates ideas from research on circular business models and circular design literature. It proposes a framework we collectively term “Future Adaptive Design” to help manage product-related business risks in circular business models and investigates related design strategies for product-based companies aiming to adopt circular business models.

Movable Possessions: alternative housing through adaptable design

Poor communities around the world have developed architecture without architects. Subsidized low-income housing has been built as if to provide only a shortterm solution. Poverty and lack of affordable housing is not a short-term problem but an ongoing issue that demands creative adaptable solutions for a changing world. Adaptable architecture is essential for the redesign of affordable housing that is environmentally, economically, and socially sustainable. In order to mend the broken bond between lower-incomes and the architectural quality of space, this design research strives to both defend and produce affordable architectural alternatives to housing through the use of adaptable design principles and strategies found within Barbados’ Vernacular Architecture, the Chattel house.

The Perceived Hazard of Sound Scheme and Desktop Theme Auditory Elements

The interface concept of adaptable design allows users to select and apply alternative auditory elements to the user interface. This study examines the consistency of the arousal strength of auditory elements that accompany exception messages available in two adaptable design options available for the Microsoft Windows operating system: (1) sound schemes and (2) desktop themes. The auditory elements available in these options differ in composition and sound features. Prior work indicates that such differences could result in differences in the arousal strength communicated by the auditory elements and therefore violate the key user interface design principle of consistency. The auditory elements within IT environments should communicate consistent levels of hazard as measured by arousal strength in order to achieve “hazard matching.” Results reveal differences in the arousal strength of the important critical stop auditory element across both sound schemes and desktop themes. Implications of this finding are discussed.

Dynamic Lifecycle Cost Modeling for Adaptable Design Optimization of Additively Remanufactured Aeroengine Components

Additive manufacturing (AM) is being used increasingly for repair and remanufacturing of aeroengine components. This enables the consideration of a design margin approach to satisfy changing requirements, in which component lifespan can be optimized for different lifecycle scenarios. This paradigm requires lifecycle cost (LCC) modeling; however, the LCC models available in the literature consider mostly the manufacturing of a component, not its repair or remanufacturing. There is thus a need for an LCC model that can consider AM for repair/remanufacturing to quantify corresponding costs and benefits. This paper presents a dynamic LCC model that estimates cumulative costs over the in-service phase and a nested design optimization problem formulation that determines the optimal component lifespan range to minimize overall cost while maximizing performance. The developed methodology is demonstrated by means of an aeroengine turbine rear structure.

Surveying the Perception of the Environmental Advantages of an Adaptable Product

The aim of adaptable design is to create products that can easily adapt to different needs. The objective if this study is to analyze the effectivenes in communication to promote an adaptable baby stroller, in order to know the user perception of the advantages derived from its adaptability, as well as the environmental ones, and if there is correlation between them. It is also intended to determine whether age or previous experience with this type of product can influence this perception. To this effect, a study with 54 participants has been conducted. Results show that users percieve the advantages and find the adaptable design interesting. Valuation of the advantages of the product is affected by previous user experience with the need for adaptability. Valuation of the environmental benefits is independent from the degree of experiense, as well as from the age of the participants (between 30 and 45 years old).
