The modern engineer needs to have diverse skills ranging from abilities in re-design, co-design, customisation, management of resources and intellectual property, combined with technical expertise. Design education needs to prepare individuals for these requirements and manage the expectations of the students concerned. A particular challenge is the disconnect between empowered design practice, where the practitioner already has the necessary skills to explore the task, and the novice who is still learning technical and design skills. In order to develop understanding of design processes commonly experienced in industry a combination of projects using fuzzy or constrained briefs are introduced in the first and second years on the MEng in Mechanical Engineering at Imperial College. Constrained briefs defining the limits for the design activity, are sometimes criticised as limiting the creative opportunities for the people involved. Some creative techniques however focus on identifying the constraints and conflicts involved with a view to resolving them. This paper explores a constrained brief project, used for the second year, where students are required to design, manufacture and then test their design for a pump. The project encourages use and exploration of analytical skills, engineering science and form development as well as basic manufacturing skills. Students can use CNC manufacture for their impeller and volute but are required to manually machine the majority of their bearing housing and shaft arrangement. The combination of concept development within constraints, use of analysis and engineering science, development of manufacturing and assembly skills and the student experience derived from testing their designs, are described within this paper.

Engineering design activities rely heavily on the richness of knowledge and information available. In order to progress their tasks, designers undertake numerous searches to answer their information requests. A review of the literature on information seeking (IS) found that the role of the types of information request on source selection has been little investigated compared with that of the source itself, the seeker, the seeker–source relationship and the work context. This paper describes the empirical research that was carried out in collaboration with the aerospace group of a major power systems company to understand the relationship between information searches and information requests raised by designers involved in individual design tasks. The empirical part of the research consisted of participating in a design activity undertaken within the collaborating company and in conducting analytical studies with its designers. Two large data sets were gathered using a diary study and observations with shadowing. Based on the literature review and empirical research, a framework to describe how engineering designers access information was developed. The context of an information request, the request itself and the associated search were characterised through three groups of categories. Designers were found to raise requests to acquire information and to process information. The main sources used to answer these requests were colleagues, databases and drawings. In examining how sources are used, the research confirmed that designers generally prefer to source knowledge and information through informal interactions with their colleagues and demonstrated that colleagues are more often consulted to answer the requests to process information and documentary sources to answer the requests to acquire information. The results on the use of the media to communicate with colleagues indicated that face-to-face interactions are preferred to answer the requests to process i

KIM S, AURISICCHIO M, WALLACE KM, 2009, Towards automatic causality boundary identification from root cause analysis reports, Journal of Intelligent Manufacturing, Vol: Vol.20, Pages: 581-591
This paper presents the results of developing andevaluating an automatic approach that identifies causalityboundaries from causality expressions. This approachfocuses on explicitly expressed causalities extracted fromRoot Cause Analysis (RCA) reports in engineering domains.Causality expressions contain Cause and Effect pairs andmultiple expressions can occur in a single sentence. Causalityboundaries are semantically annotated text fragmentsexplicitly indicatingwhich parts of a fragment denote Causesand corresponding Effects. To identify these, linguistic analysisusing natural language processing (NLP) is required.Current off-the-shelf NLP tools are mostly developed basedon the language models of general-purpose texts, e.g. newspapers.The lack of portability of these tools to engineeringdomains has been identified as a barrier to achieving comparableanalysis accuracy in new domains. One of the reasonsfor this is the rare and unpredictable behaviours of certainwords in closed domains. Ill-formed sentences, abbreviationsand capitalization of common words also contribute to thedifficulty. The proposed approach addresses this problem byusing a probability-based method that learns the probabilitydistribution of the boundaries not only from the NLP analysisbut also from the local contexts that exploit languageconventions occurred in the RCA reports. Using a collectionof RCA reports obtained from an aerospace company, a testshowed that the proposed approach achieved 86% accuracy outperforming a baseline approach that relied only on theNLP analysis.

Documented engineering design rationale has the potential to become a key source of information about past designs. Easeof comprehension of design rationale might play a crucial role in ensuring that the full potential of documented informationis realized and that the effort and time necessary to capture design rationale pay off. This research proposes an empiricalmethodology for evaluating how structuring design rationale and supplying it with visual nontextual cues influences readingand interpretation. The study compares reading and interpretation of technical documentation presented in different formatsto engineering graduate trainees in the aerospace industry.

Industrial organisations increasingly rely on empirical research projects to develop a better understanding of their processes. If the aim of a research project is to identify the fundamental factors influencing the design process, then a detailed study of that process is necessary. Several studies have been undertaken in academic environments to study either natural or controlled design processes. Undertaking detailed studies in industry is challenging and poses several research issues. A review of engineering design literature showed that little has been published on the competencies required by researchers carrying out such empirical studies, as well as on the characteristics of participants. This paper identifies and discusses key competencies and characteristics, based on the literature and the experience gained by the authors during a detailed research project, in collaboration with the aerospace group of a major power systems company.
