Lipinski T, Lee SH, Childs PRN, 2014, Domestic Passive Ventilation with Heat Recovery (PVHR): Performance criteria, tests and operational variations
Historically, housing in general has had low levels of insulation and poor airtightness. Although this characteristic was not energy efficient it provided a plentiful supply of fresh air. Over the last twenty years insulation and airtightness of homes has received attention due to a global drive towards energy efficiency and carbon emissions reduction. Since a large portion of energy used in homes is utilised for comfort heating or cooling, the focus has been on improvements to insulation and airtightness in order to decrease the dwellings' total energy use, as well as ensuing carbon emissions. However, a large body of research shows that airtight houses require adequate air management (controlled ventilation) to prevent the occurrence of poor indoor air quality which can contribute to illness such as asthma as well as the so-called sick building syndrome. Introduction of controlled ventilation presents another energy related challenge - fresh air introduced to homes needs to be re-heated (or cooled) adding to energy use and negating most gains resulting from improved insulation. Even if Mechanical Ventilation with Heat Recovery (MVHR) is used, the systems use electricity and require maintenance to operate, adding to cost and reducing energy savings. Thus an air management system that can improve building ventilation, prevent excessive heat loss and use no energy in operation is a desirable option. The Ventive PVHR technology, described in this paper, can be such an option that provides efficient ventilation with heat recovery and no electricity use. This system utilises both thermal buoyancy and pressure caused by the wind-driven Pitot effect of a cowl as its two driving forces. Advances in heat exchanger design resulting in interleaved coaxial heat exchanger units allow the thermal energy of the outlet air to be exchanged to the cooler inlet air with consistently high efficiency and negligible pressure drop. Thus heat loss due to air ventilation can be minimised a

A core design and manufacture group project has been run in the second year of the Mechanical Engineering undergraduate programme at Imperial College for over two decades where students are required to develop highly loaded rotating machinery, such as a pump or a winch, early in the second year of their undergraduate study. The aim has been to provide a practical opportunity to apply and develop skills learnt in the first year and to provide the experience of manufacturing, operating and testing what has been designed. While these projects have been a mainstay of the educational experience for many years, there has been a persistent concern that the projects are deterministic and highly constrained. The course team and student body have debated and now implemented a new project that is both less constrained and more appealing to the student cohort. In this project the students are tasked with developing a transmission for an electric scooter. The project has resulted in a significant diversity in designs and, importantly, the students embracing the curriculum content with fervour. The challenge still requires attention to the application of fundamental mechanical engineering principles such as transmissions, solid mechanics and materials, but also focuses on electronic control systems, battery and motor characteristics, high current and power, health and safety and a range of transferable skills. The multi-disciplinary nature of the project combined with an appealing application has resulted in a highly engaged year group. This paper reports on the project and includes an analysis of the diversity of designs and student effort.

Design and engineering have worldwide impact. The products and systems generated affect every level of our lives. In a competitive world where the prosperity of local industry waxes, wanes and emerges in new forms, temporal strategies and policies for survival and gain inevitably emerge. It is in this context that engineers and designers operate their exciting trades, with consideration of multiple functional attributes in any given application. This may involve attention to technical, aesthetic, economic, social and latent function and their often complicated interrelationships, with one attribute affecting the performance of others in a significant manner. The value of each attribute needs to be maintained at the design stage in order to deliver worldwide competitive products, systems and services. It is in the conceptual, detailed design, fire-fighting and application phases that engineering analysis shows its potential, time and time again, to deliver order-of-magnitude as well as validated estimates for quantities. The tools of engineering provide essential input and infl uence for the design process. These tools can be operated with diligence and exacting analysis, as well as in the fast-paced conceptual stages of any project, in order to explore the 'what if' and to provide a physical basis for an idea, as well as the impetus to give that idea the justification for the resources it requires for elaboration. © Manchester University Press.

Childs PRN, Zhao Y, Grigg J, 2013, Narrative in design development, Pages: 108-113
This paper describes the value of narrative used with ideation tools in aiding the rapid production of product concepts and designs for masters students of graphics, fine art, product and industrial design. The ideation tools used alongside narrative included elements of divergent and convergent thinking in combination with reverse engineering and functional analysis, and practical prototyping using a range of readily adapted artefacts. Narrative was introduced and used by the students in order to ensure the development of a context and purpose for the product, artefact or system developed or proposed and to stimulate original product concepts, ideas and thinking. The concept of narrative is familiar in design. Here however the concept was reinforced using structures associated with fictional narrative. Reverse engineering exploring the deconstruction and identification of function for each component in a product was used to aid students ensure practicality in their idea implementation. This paper describes positive experiences resulting from this activity, with a particular focus on the value of narrative in developing robust concepts. The use of physical prototyping provided tangible and instant feedback for divergent and convergent phases of idea development.

Nam TJ, Childs P, Sohn M, 2013, A design model and tackles for systematic conceptual design, International Journal of Mechanical Engineering Education, Vol: 41, Pages: 341-353, ISSN: 0306-4190
Systematic design models are useful in the professional education of both designers and engineers; they also support complex multi-faceted design activities that involve a large number of individuals. This paper introduces a range of design models, but then focuses on the linked node model, which uses nodes to indicate the properties of an outcome and links to show the connections between the nodes. The model is based on the premise that good design serves to generate a harmoniously integrated outcome. The paper also explores a range of tools and 'design tackles' that can be used in a systematic approach to design. Finally, it introduces a design project aimed at creating better user experiences in Dongdaemun market in Seoul, Korea. © Manchester University Press.

For the last three years a course has been offered to MEng students in their third or fourth year of studies called Design Led Innovation and New Venture Creation. The rationale for offering the course was a combination of demand for design orientated options as well as the desire to deepen students' understanding and experience of the process of realising their ideas and ventures commercially. The premise for the course is that successful design-led innovation depends on blending customer insight and technical inventiveness to create value for customers and users as well as commercial value for innovative firms and their investors. Students are coached intensively in interdisciplinary teams by design experts, engineers and entrepreneurs to develop a project into a business proposition. Theproject ideas are formed in response to the positing of a meta-theme. Students are exposed to keyconcepts in design, creativity tools and the disciplines of human-centred design as well as strategies for introducing new products or services to a market and developing the necessary value networks. A key outcome of the course has been the emphasis necessary for ensuring that the process of preparing a new venture is considered and acted upon. This has been realised by means of intensive tutoring by experienced and practicing entrepreneurs. This paper reports the student experience along with the series of interventions that have been necessary in order to develop behaviours compatible with turning technical inventiveness into potentially viable innovation propositions.

Design can have an influence far beyond the initial activity on a product, processor system. Design represents a dynamic entity as a result of the interactions withthe user and the context. Once released, a design can be adopted for uses, notinitially considered, sometimes with unintended consequences. The world of designis used to the reach of the domain, and it is within this context that the RioTinto Sports Innovation Challenge was initiated.The intention was to explore Paralympic sports, to see what design could offer.A wide open brief was developed and we pressed go. This book presents thecontributions of the many participants, students, elite sportsmen and women,domain experts and course staff.

Engineering Design Theory as an integral part of design education serves the purpose of structuring actions and thinking processes in order to increase the efficiency of development processes and the quality of developed products. In many institutions in Europe and the U.S.A., problem-oriented process models based on the approach of functional decomposition have complemented teaching approaches that rely on studying standard solutions such as machine elements. If one assumes that these models have been designed to suit the thought habits and educational traditions in the cultural spheres of their origin, their validity in the context of the globalization of engineering education must be discussed. Especially with regards to "Western" and "Asian" cultures, Nisbett  substantiates the existence of profound cognitive differences that might be relevant for design education and practice. Summarizing some of Nisbett's assertions, Westerners are more likely to rely on categorizing and individualizing objects and applying formal logic in any situation, whereas Asians prefer not to disentangle objects from their context in favour of a more holistic view of the world. This paper explores the consequences of such cultural differences in the context of product design and development to add plausibility to the authors' own observations from teaching practice with students from China, Germany, South Korea, Thailand and the United Kingdom. The discussion focuses on the applicability of the established model of the Engineering Design Process, narrowing the scope of Design Theory but broadening on the view that different design practices are attributed solely to differences in social interactions.
