Printoo – from here to the Internet of Things

This thesis is a pedagogical case study on Strategy applied to Innovation, using Printoo – a product by Ynvisible – as a setting. Hence, the focus of this case is to describe and analyze the challenge of this company and its managers to define a fit strategy for its new, innovative product. Printoo’s concept is highly innovative and it is inserted in an area of technological development with great potential – Printed Electronics. Several tools and trends influence this area, such as the Makers culture, Crowdfunding, Open-Source and the increasing use of Technology in Education. Furthermore, there is a debate on implementing the concept of the Internet of Things – in which Printed Electronics may have a role. From the interviews and analysis performed, this paper has two key conclusions. The first one is that Ynvisible should focus on both Printoo – a series of kits of Printed Electronics technologies components – and on the company’s own proprietary Electrochromic displays – that are included in Printoo – in order to maximize the power it has over the potential profits that will derive from this innovation, because Printoo is highly imitable and the displays are not. Nevertheless, Printoo is an important marketing tool to promote Ynvisible’s displays and other components from suppliers. The second conclusion is that Education is an important market that Printoo should address, and that the approach should combine continuous improvement – of the technologies that the kits contain and of the experiences they allow to perform – and service improvement – as courses and workshops – which actually Ynvisible is starting to do. Other markets are also important, such as the Makers, Open Source market and the Prototyping market

A comparison of processing techniques for producing prototype injection moulding inserts.

This project involves the investigation of processing techniques for producing low-cost moulding inserts used in the particulate injection moulding (PIM) process. Prototype moulds were made from both additive and subtractive processes as well as a combination of the two. The general motivation for this was to reduce the entry cost of users when considering PIM. PIM cavity inserts were first made by conventional machining from a polymer block using the pocket NC desktop mill. PIM cavity inserts were also made by fused filament deposition modelling using the Tiertime UP plus 3D printer. The injection moulding trials manifested in surface finish and part removal defects. The feedstock was a titanium metal blend which is brittle in comparison to commodity polymers. That in combination with the mesoscale features, small cross-sections and complex geometries were considered the main problems. For both processing methods, fixes were identified and made to test the theory. These consisted of a blended approach that saw a combination of both the additive and subtractive processes being used. The parts produced from the three processing methods are investigated and their respective merits and issues are discussed

Reducing risk in pre-production investigations through undergraduate engineering projects.

This poster is the culmination of final year Bachelor of Engineering Technology (B.Eng.Tech) student projects in 2017 and 2018. The B.Eng.Tech is a level seven qualification that aligns with the Sydney accord for a three-year engineering degree and hence is internationally benchmarked. The enabling mechanism of these projects is the industry connectivity that creates real-world projects and highlights the benefits of the investigation of process at the technologist level. The methodologies we use are basic and transparent, with enough depth of technical knowledge to ensure the industry partners gain from the collaboration process. The process we use minimizes the disconnect between the student and the industry supervisor while maintaining the academic freedom of the student and the commercial sensitivities of the supervisor. The general motivation for this approach is the reduction of the entry cost of the industry to enable consideration of new technologies and thereby reducing risk to core business and shareholder profits. The poster presents several images and interpretive dialogue to explain the positive and negative aspects of the student process

Rapid Prototyping Methodology of Lightweight Electronic Drivers for Smart Home Appliances

Many researches have been conducted in smart home topic. Mostly, they discussed on the specific aspect of application. On the other side, many applications still can be explored and attached into the system. Several main challenges in designing the application devices are system complexity, reliability, user friendliness, portability, and low power consumption. Thus, design of electronic driver is one of the key elements for overcoming these challenges. Moreover, the drivers have to comply the rules of smart home system, data protocol, and application purpose. Hence, we propose a rapid prototyping methodology on designing lightweight electronic drivers for smart home appliances. This methodology consists of three main aspects, namely smart home system understanding, circuitry concept, and programming concept. By using this method, functional and lightweight drivers can be achieved quickly without major changes and modifications in home electrical system. They can be remotely controlled and monitored anytime and from anywhere. For prototyping, we design several drivers to represent common electronic and mechanical based applications. Experimental results prove that the proposed design methodology can achieve the research target

The Potential of Printed Electronics and Personal Fabrication in Driving the Internet of Things

In the early nineties, Mark Weiser, a chief scientist at the Xerox Palo Alto Research Center (PARC), wrote a series of seminal papers that introduced the concept of Ubiquitous Computing. Within this vision, computers and others digital technologies are integrated seamlessly into everyday objects and activities, hidden from our senses whenever not used or needed. An important facet of this vision is the interconnectivity of the various physical devices, which creates an Internet of Things. With the advent of Printed Electronics, new ways to link the physical and digital worlds became available. Common printing technologies, such as screen, flexography, and inkjet printing, are now starting to be used not only to mass-produce extremely thin, flexible and cost effective electronic circuits, but also to introduce electronic functionality into objects where it was previously unavailable. In turn, the growing accessibility to Personal Fabrication tools is leading to the democratization of the creation of technology by enabling end-users to design and produce their own material goods according to their needs. This paper presents a survey of commonly used technologies and foreseen applications in the field of Printed Electronics and Personal Fabrication, with emphasis on the potential to drive the Internet of Things

Frankenstein's Toolkit: Prototyping Electronics Using Consumer Products

In our practice as educators, researchers and designers we have found that centering reverse engineering and reuse has pedagogical, environmental, and economic benefits. Design decisions in the development of new hardware tool-kits should consider how we can use e-waste at hand as integral components of electronics prototyping. Dissection, extraction and modification can give insights into how things are made at scale. Simultaneously, it can enable prototypes that have greater fidelity or functionality than would otherwise be cost-effective to produce

Improving African healthcare through open source biomedical engineering

The lack of accessible quality healthcare is one of the biggest problems in Africa and other developing countries. This is not only due to the unavailability of resources, but also to the absence of a structured formative process for the design and management of healthcare facilities. Crucial to the effective and efficient exploitation of healthcare facilities and biomedical technology is the support of Biomedical engineers, who form the link between technology and medical practice. Indeed Biomedical engineers, together with nurses and doctors, form the pillars of healthcare systems in the developed world. In this paper, the Open Source for BioMedical Engineering (OS4BME) project and its kick off summer school are presented. The OS4BME project aims at developing a new generation of biomedical engineers, able to exploit emerging technologies generated by the recent "Makers" revolution. During the one week summer school, students from various sub-Saharan countries were introduced to these new design, development and sharing paradigms. Students worked together to identify new simple biomedical devices, which could help in daily clinical practice in their countries. A cheap and easy-to-use neonatal monitoring device was chosen as a Crowd design project. The OS4BME Baby Monitor was designed and assembled by the students during the one week summer school, demonstrating the creative potential of the new generation of biomedical engineers empowered with the paradigms of crowdsourcing and rapid prototyping
