It is the aim of this study to present a framework for the design of technical systems. This can be achieved through a general Design Science, a knowledge system in which products are seen as objects to be developed within engineering design processes. The authors have developed this design science from a division of the knowledge system along two axes. One deals with knowledge about technical systems and design processes while the other presents descriptive statements. Relationships among the various sections of the knowledge system are made clear. Well-known insights into engineering design, the process, its management and its products are placed into new contexts. Particular attention is given to various areas of applicability. Widespread use throughout is made of easily assimilated diagrams and models.

Principles of Engineering Design discusses design applicability to machine systems, the nature and scope of technical processes, technical systems, machine systems, the human design engineer, the design process, and cases related to methods and procedures. The text deals with the structure, mode of action, properties, origination, development, and systematics of such technical systems. It analyzes the design process in terms of case problems, modelling, structure, strategies, tactics, representation, and working means. It also describes in detail the general model of a methodical procedure: separate design steps are treated in a unified fashion from different perspectives. The text notes that the tasks and methods of design research involve the following: (1) Components—determining structural elements in the design process; (2) Sequence—determining a general procedural model for the design process with a minimum of failures; (3) Modifications—what changes in factors affect the design process; and (5) Tactics—selection for individual design operations to obtain optimal results. A case study exemplifies the significant stages of design of a welding positioner. The book is highly recommended for students and the practicing design engineer in various fields.

This book presents a comprehensive and unifying theory to promote the under­ standing of technical systems. Such a theory is useful as a foundation for a ratio­ nal approach to the engineering design process, as a background to engineering education, and other applications. The term "technical system" is used to represent all types of man-made artifacts, including technical products and processes. The technical system is therefore the subject (in the grammatical sense of the word) of the collection of activities which are performed by engineers within the processes of engineering design, including generating, retrieving, processing and transmitting of information about products. It is also the subject of various tasks in the production process, including work preparation and production planning, and in many economic considerations, company-internal and societal. In this way, the Theory of Technical Systems is a contribution to science, as in­ terpreted in the wider, Germanic sense of a "co-ordinated and codified body of knowledge". It brings together the various viewpoints of engineers, scientists, economists, ergonomists, managers, users, sociologists, etc., and shows where and how they influence the forms of engineering products. It also explains the influ­ ences that a product exerts on its environment. This Theory of Technical Systems should thus interest design engineers, and en­ gineers involved in production, management, sales, etc. In an interdisciplinary ap­ plication of value analysis, the Theory of Technical Systems should provide answers to many questions raised in this field.

Mit diesem Buch wird das Konstruieren, eine der Hauptaufgaben des Ingenieurs, auf ein wissenschaftliches Fundament gestellt. Dies geschieht inerster Linie mit dem Ziel, Studenten von Universit{ten und Fachhochschulen in eine neue Denkweise einzuf}hren, die ihre sp{tere praktische Arbeit zu systematisieren gestattet. Es wendet sich aber auch an den bereits konstruktiv t{tigen Ingenieur, dem es sein meist extrem umfangreiches Wissenordnen hilft. Das Buch gliedert sich in drei Teile: I. die Beschreibung des Konstruktionsprozesses, II. der Weg von loser Wissensanh{ufung zur Ordnung, III. die Ableitung spezieller Wissenssysteme aus der allgemeinen Konstruktionswissenschaft.Darstellung und Strukturierung des Textes sowie Auswahl und Aufbau der Bilder folgen den f}r diese Aufgabe erarbeiteten didaktischen Prinzipien.

Die Theorie der Maschinensysteme bildet den ersten Teil einer wissenschaftlichen Konstruktionslehre. Das Maschinensystem als Repräsentant aller Arten von Maschi­ nenprodukten ist Gegenstand der Verarbeitung nicht nur im Konstruktionsprozeß, sondern auch in der Vorbereitung der Fertigung und im Fertigungsprozeß, sowie in vielen wirtschaftlichen Uber1egungen. Deshalb muß die Theorie der Maschinensyste­ me nicht nur den Konstrukteur, sondern auch den Fertigungs-, Betriebs- und Ver­ kaufs-Ingenieur interessieren. Für die interdisziplinäre Wertanalyse beantwortet die Theorie der Maschinensysteme viele Fragen, die auf diesem Gebiet auftauchen. Besonders im Hinblick auf die Studenten aller dieser Richtungen hoffe ich mit dem Aufzeigen neuer Gesichtswinkel auf dem Gebiet des Maschinenbaues zu einem besseren Verständnis der Problematik beizutragen. Die vorliegende Arbeit verfolgt mehrere Ziele: einmal, die Arbeitsweise, die Kate­ gorien und die Eigenschaften der Maschinensysteme zu behandeln, dann auch, die grundlegende Terminologie der Konstruktionslehre aufzubauen und letztlich, wich­ tige Erkenntnisse über Maschinensysteme zu formulieren, auf welche sich weitere Kapitel der Konstruktionslehre, besonders über Arbeitsmethoden stützen werden. Von dieser Zielsetzung her mag dieser Teil etwas trocken und theoretisch erscheinen. Es soll aber nicht Aufgabe des Lesers sein, diesen Stoff von Grund auf zu studie­ ren, vielmehr möchte das Buch als Nachschlagewerk dienen, zu dem man immer wieder greift.
