In systematic design the overall function is the relationship between inputs and outputs of a plant, machine, or assembly. This overall function is defined by the requirements and it is usually divided into sub-functions to be solved separately, because it is easier to find solutions for the smaller sub-functions. Finding the sub-functions and the solutions(More)
Current trends in production are leading to one-of-a-kind products designed and manufactured in shorter time. The pressures of emerging design requirements, e.g. safety and recycling, are importing new disciplines to the tightening design schedules. Specialized software tools are able to solve individual problems, but the data exchange capabilities of these(More)
1. Aims and objectives Global competition has forced companies to redesign themselves (Leifer et al., 2000). The goal of redesign has been to strengthen a company’s position as one of leading companies in the world. One well-known example is Metso Corporation with its three core business areas. Two of these business areas have about half of global markets.(More)
According the present thinking, a function based platform approach is most virtuous for configurable products. Although there are successful cases of utilising this type of platform in industry, success has often been only temporary. This is due that challenges set by long-term platform life cycle management has not been addressed adequately. Dynamic(More)
Interfacing knowledge based engineering systems and object-oriented databases allows utilization of the best features of the both worlds. Methods of object-oriented databases enable storaging, in addition to simple technical data, e.g. large part of component speciic knowledge into the database. In this paper we present object-oriented views, which allow(More)
Several methods of modeling systems are common in TRIZ for problem solving, system simplification, and improvement. Subject – Action– Object models are based on specific physical components of a system and the explicit effects they exert on other components of the system, and are derived from the Su-field modeling method of classical TRIZ. “Operational”(More)
Advanced design support solutions such as 3D simulations have enabled improved management of design information for years. The challenge, however, is that acquiring these type of design support solutions does not necessarily create a visible business value for the company in a short run. Moreover, the organization surrounding the simulation solution should(More)
