Cognitive design of products for engineering and vibromechanics by criterion of minimization labor input of their manufacturing

The basis of the algorithm for determining the labor input are user-configured according to the parameters of its real production. It is shown that in the early stages of designing the designer can minimize the expected cost of the product by changing the design solutions, its head by a reporting engine will evaluate the range of materials and assortments and will issue guidelines to reduce it, and the technology and setters will calculate the final demand for materials and labor. Developed labor regulation system, built on the theory of fuzzy decision trees

The Relevance of Rigour for Design Practise

Design is an inverted discipline. The concept of rigour, as understood within the natural sciences, cannot be applied to Design Practice. Rigour for the natural sciences is a quality assurance mechanism ensuring that the knowledge bases of the disciplines are developed to an accepted set of standards. Design’s ontology is not like the natural sciences and as such an understanding of rigour for Design must proceed from an appropriate standpoint about the nature of Design Practice. This paper builds upon Harfield’s [1] ontological assessment of Design, Schön’s [2] [3] work on Reflective Practice and Spencer’s [4] investigation into the experience and practise of designing to develop a standpoint about Design Practice and make a proposition about the relevance of rigour for Design Practise. This paper considers how individual Reflective Practice practitioners, within the context of Design Practice, manage and ensure quality control through the application of care and thoroughness. This paper argues that rigour for Design Practise is the personal and phenomenological quality control of a design inquiry: a process of managing expanding mental chaos and restricting order

Drawing, (building), writing

This paper argues that it is crucial to conceptualize the difference between the notions "design rationale" and "discursive rationale". Awareness of the rational component in the design process may not be confused with having "theoretical knowledge" on the way designers design. We do not define the act of designing as a "discursive process" in which every step taken can be argued and covered with theoretical knowledge. That's why the description (and the analysis) of a certain "design rationale" is distinct from the "practical design knowledge" as we find in design guides. When we really want to think about "design" we have to articulate the interstice between thinking, writing and designing

Innovative lightweight aircraft design : a student competition

Education in engineering design is a challenging task. On the one hand the students have to get a broad theoretical basis and engineering expertise, on the other hand they have to learn how to apply their knowledge and how to face real technical problems [Pulko, 2004]. Since time in University is limited (in Germany a engineering degree at university level takes about 5 years to complete) often an emphasis is put on a sound theoretical education at the expense of practical experience. This paper presents a student competition between four German universities, which provides a practical team-work project for engineering (design) students that nearly spans the whole life-cycle from brainstorming for product ideas to manufacturing and usage of the product. The development task is an aircraft or flight device totally made of steel. Aim of the project is to apply the theoretical knowledge at a practical task

Structural design of Abutment Using GEO 5 Program

The soil mechanics and designing technique got the revolution quickly in the 2000’s, especially in Indonesia which has many types of soil. By the developing technology era of construction building, it is also in the geotechnical technology. To make easy in the designing of foundation, especially; abutment, the using of software is also needed. Based on the problem above, the writer want to investigate the usage of program in designing the abutment, the program is Geo5. In this designing, the data is taken from Pagotan Bridge Rehabilitation, Pacitan. Central Java. The abutment with concrete as the structure, controlling the stability of sliding, overturning, soil weight volume (ɤ) 1,424 gr/cm3; cohesion (c) 0 kN/cm2; friction angle (φ) 30o.The geology condition of soil layer in the field is sand; the high of abutment is 5.8 m. The calculation method is done twice; manual calculation and Geo5 program calculation. After the calculation, the result show that the stability manual factor of sliding is 2.04>2 (safety), stability of overturning 3.07>2 (safety). The differences result between manual calculation and Geo5 program is because the calculation of lateral earth pressure is difference. The manual calculation used Rankine while Geo5 program used modification Rankine, it is Mazindrani

Off to a Good Start - Or How to put the 'T' in C.D.T

The pungent smell of machine oil mingled with disinfectant prevails the workshop air. Lathes stand gleaming, a little worse for wear but devoid of swarf and bits of metal. Floors and benches swept clean, tool cupboards, racks full, vacant places replenished with sharpened dividers and scribers. Files, try squares, calipers, all recolour coded with a fresh coat of paint. Another school year and the beginning of a new term. The noise of Third Years lining-up in the corridor cracks the atmosphere, eager, expectant, demanding bodies rush and jostle. Mixed ability, mixed emotions, mixed sexes, all mixed up in groups of twenty-ones.Finding a project, topic, problem, need, situation, design brief, whatever we call it that involves a total Craft, Design and Technology concept and experience is difficult. No, you may say, it's easy - just set a design problem such as design and make a small hammer, box, egg-holder, toothbrush rack and so on. Good old standbys, never fails, grabs their interest, teaches skills, functional end product - 'Something to show Mum and Dad'. But ask yourself is it CDT? Producing a design problem that is stimulating, demanding and relevant to that age group and combines the following:(a) that encourages the development of each pupils' potential both in cognitive and manipulative skills.(b) encompasses the whole essence of what CDT is about.I would suggest that points (a) and (b) are a challenge for many new and even established teachers.Probably one of the main reasons for this situation occurring is what I call 'The Great Technological Syndrome'

Capitalising on the utility embedded in design and technology activity : an exploration of cross-curricular links

Despite international support for cross-curricular activity involving design and technology, science and mathematics classroom practice in secondary schools has been unable to respond positively or effectively. This paper explores the ideas of purpose and utility as drivers to enable collaboration between teachers from these subjects and suggests ways in which this collaboration might take place

Services Aren\u27t Goods: Post-Industrial Principles for Policy Design

As the United States moves from an industrial society to a post-industrial society, fewer people are engaged in the production of goods, and a majority now produce services. The processes of designing and producing goods and services are radically different. This differences calls for innovation in both the structure of the work setting and the policies which govern work in the society as a whole. The article examines differences between goods and services and proposes a new model for designing and producing services, as well as new principles for social policy for service production. The model and principles are illustrated with examples in health care
