A HOUSE THAT GROWS ON THE INSIDE

<p>With house prices rising so rapidly, many New Zealand families find the stretch to homeownership beyond them. It is now customary to hear of people unable to purchase a property for their needs, in relation to the size of the house, its location or both and the idea of homeownership is fast becoming a pipeline dream for most people. With large upfront costs and large mortgage repayments, the cost of purchasing or building a house is unaffordable for a growing number of the population (Aravena & Lacobelli, 2012; Michael Bassett, 2013). Affordability is a broad notion but in essence, this research portfolio addresses it as the concern for accessibility of New Zealanders to put a roof over their heads. The crux of this issue is the relatively high cost to purchase a place to call home, making housing a commodity to enrich a few. An alternative solution to building and financing a home is needed. This research portfolio questions how flexible design and incremental construction approaches can be applied to a range of sites typical to the New Zealand context, providing an alternative housing solution that addresses housing affordability. This alternative housing solution demonstrates flexible design and incremental construction tactics derived from the comparative and critical analysis of literature and precedence. These tactics are demonstrated through the design of four typologies that accommodate the users changing needs and financial circumstances. Housing affordability has been addressed by the consideration of these flexible design and incremental construction tactics to allow for incremental investment. As the users, financial circumstances increase or change, the design and construction of their dwelling allows them to make changes easily. This reduces the need for major construction work in order to change the layout and use and it easily allows for the opportunity to expand when the money becomes available. It also averts the necessity to move which in the current property market is costly in terms of finances and time. To address the aims of this research portfolio, this alternative housing solution inverts the typical process of building and financing a home. It responds effortlessly to the occupant’s requirements, however varied. Incorporating flexible design and incremental construction tactics allows for incremental change and incremental investment over the lifetime of the building. At times when a lack of supply has resulted in rampant price increases, we need to question why, would one build a house that takes a great amount of time, money and effort to construct but so quickly becomes redundant? A dwelling, therefore, shouldn’t be a product. A dwelling should be an ongoing process.</p>

Flexibility “of” vs. “in” Systems: A Complementary Strategy for Designing Fleet-Based Systems for Uncertainty

Complex systems must sustain value over extended lifetimes, often in the face of significant uncertainty. Flexibility “in” systems has been shown to be highly valuable for Large Monolithic Systems (LMS). However, other research highlighted that the value of flexibility “in” is highly contingent on delays in implementation. These limitations become more important when applied to other classes of complex systems, including Fleet-Based Systems (FBS). To overcome these challenges, this paper introduces a complementary approach to flexible design, termed “Flexibility ‘of’” and applies it to a case study of a fleet of military vehicles (an FBS). Unlike LMS, FBS are composed of multiple identical units that collectively deliver value. While each unit is itself a complex system (e.g., a tank or aircraft), the collective nature of the operations provides additional paths to flexibility: in addition to implementing flexibility at the vehicle level, flexibility can be applied to the management of the fleet. Flexibility “of” involves procuring a mixed capability fleet upfront and then actively managing which subsets of that fleet are deployed to meet emerging needs. Our results demonstrate the potential value for an “of” strategy and provide guidance for when different flexibility strategies should be adopted alone or in combination.

Robustly printable freeform thermal metamaterials

Thermal metamaterials have exhibited great potential on manipulating, controlling and processing the flow of heat, and enabled many promising thermal metadevices, including thermal concentrator, rotator, cloak, etc. However, three long-standing challenges remain formidable, i.e., transformation optics-induced anisotropic material parameters, the limited shape adaptability of experimental thermal metadevices, and a priori knowledge of background temperatures and thermal functionalities. Here, we present robustly printable freeform thermal metamaterials to address these long-standing difficulties. This recipe, taking the local thermal conductivity tensors as the input, resorts to topology optimization for the freeform designs of topological functional cells (TFCs), and then directly assembles and prints them. Three freeform thermal metadevices (concentrator, rotator, and cloak) are specifically designed and 3D-printed, and their omnidirectional concentrating, rotating, and cloaking functionalities are demonstrated both numerically and experimentally. Our study paves a powerful and flexible design paradigm toward advanced thermal metamaterials with complex shapes, omnidirectional functionality, background temperature independence, and fast-prototyping capability.

Embodied Intelligence in Soft Robotics Through Hardware Multifunctionality

The soft robotics community is currently wondering what the future of soft robotics is. Therefore, it is very important to identify the directions in which the community should focus its efforts to consolidate its impact. The identification of convincing applications is a priority, especially to demonstrate that some achievements already represent an attractive alternative to current technological approaches in specific scenarios. However, most of the added value of soft robotics has been only theoretically grasped. Embodied Intelligence, being of these theoretical principles, represents an interesting approach to fully exploit soft robotic’s potential, but a pragmatic application of this theory still remains difficult and very limited. A different design approach could be beneficial, i.e., the integration of a certain degree of continuous adaptability in the hardware functionalities of the robot, namely, a “flexible” design enabled by hardware components able to fulfill multiple functionalities. In this paper this concept of flexible design is introduced along with its main technological and theoretical basic elements. The potential of the approach is demonstrated through a biological comparison and the feasibility is supported by practical examples with state-of-the-art technologies.
