Real Essence

When we think of paper-folding, we usually think first of the name that is usually associated with it: origami. But in the field of architecture, origami is more than just imagining an animal or flower which is what this word usually brings to mind. In architecture, we extend the meaning to take in the real essence of the word – that of great structural and constructional loads. The basic unit of origami – the fold – allows us to start manipulating space and even to create space itself. Paper-folding, with its spatial modelling potential, is to three-dimensionality what drawing is to two-dimensionality. It is after all an ancient Japanese art which encapsulates the advantages of intuitive thinking and fast modelling, once the basic elements of folding are known. Heino Engel (2001) in his book “Structural Systems”, describes intensive studies on types of structures which derive from this systematization. And the architect Ming Tang often uses structures in his projects which clearly originate in the concept of origami, and he correlates these structures with sustainable materials. The architect Michael Hansmeyer manages to incorporate all the beauty of the action of folding with the help of a computer, where the final result is a shape that approaches a real application at an architectural level. Over time, there have been numerous people who have found a relationship between the harmony and proportions of paper-folding and their own studies and projects. What is missing is a single point where clear concepts on the possibilities of folding and the results of those who have experimented with it can be brought together. This cataloguing, which is being carried out in this Master’s dissertation, is intended to be a contribution to the design method in architecture, through which the architect may achieve spatial dexterity over a piece of paper.

Inverse Design Method

A new dual-point inverse blade design method was developed and applied to the redesign of a highly loaded transonic vane, the VKI-LS89, and the first 2.5 stages of a low speed subsonic turbine, the E/TU-4 4-stage turbine that is built and tested at the university of Hannover, Germany. In this inverse method, the blade walls move with a virtual velocity distribution derived from the difference between the current and the target pressure distributions on the blade surfaces at both operating points. This new inverse method is fully consistent with the viscous flow assumption and is implemented into the time accurate solution of the Reynolds-Averaged Navier-Stokes equations. An algebraic Baldwin-Lomax turbulence model is used for turbulence closure. The mixing plane approach is used to couple the stator and rotor regions. The dual-point inverse design method is then used to explore the effect of different choices of the pressure distributions on the suction surface of one or more rotor/stator on the blade/stage performance. The results show that single point inverse design resulted in a local performance improvement whereas the dual point design method allowed for improving the performance of both VKI-LS89 vane and E/TU-4 2.5 stage turbines over a wide range of operation.

Curve Simplification

Pipeline segmentation design is the first step to design alignment sheet. In this step, several rectangular boxes are used to cover pipeline and each box will become the basic unit of alignment sheet design. After studying various pipeline alignment sheet mapping technologies, the author found that traditional manual design method, which can take advantage of designers’ subjectivity, causes low work efficiency. By reviewing and studying existing works at home and abroad, the author believed that it is possible and feasible to develop an automatic segmentation algorithm based on existing curve simplification algorithms to improve to improve the efficiency of pipeline section design and alignment sheet mapping. Based on several classical curve simplification algorithms, the author proposed the automatic segmentation algorithm, which automatically adjusts the location of rectangular boxes according to the number of pipeline/circle intersection points and pipeline/ rectangular box intersection points. Finally, through comparing time and result with the traditional manual method, the author proved the algorithm’s effectiveness and feasibility.

AbstractThe design of three-dimensional (3D) microstructures is an interesting, fascinating and highly challenging research topic. One of the very promising approaches for 3D microstructuring, inspired by the Japanese art of paper folding – origami, is based on self-folding films. Such films consist of two kinds of materials with different volume expansion properties and are able to form different structures ranging from simple tubes to highly complex 3D shapes. In this review, our recent progress in the design of polymer bilayers and understanding of their folding is summarized.

Further Development

This article presents a framework for the design process of structural systems based on the notion of topological interlocking. A new design method and a computational tool for generating valid architectural topological interlocking geometries are discussed. In the heart of the method are an algorithm for automatically generating valid two-dimensional patterns and a set of procedures for creating several types of volumetric blocks based on the two-dimensional patterns. Additionally, the computational tool can convert custom sets of closed planar curves into structural elements based on the topological interlocking principle. The method is examined in a case study of a building floor. The article concludes with discussions on the potential advantages of using the method for architectural design, as well as on challenging aspects of further development of this method toward implementation in practice.

Low Profile

This paper presents a simple, compact and low-cost design method that allows one to obtain low-profile multi-band antennas for the overcrowded future generation networks, which are widely versatile and very heterogeneous in the K/Ka bands. The proposed antennas comprise n radiating monopoles, one for each of the desired operating frequencies, along with a frequency selective feeding network fed at a single point. This concept enables a single antenna to be shared with different radio-frequency (RF) frontends, potentially saving space. Typically, with n-band structures the biggest challenge is to make them highly efficient and here this is assured by multiplexing the frequency, and thus isolating each of the monopoles, allowing the design of scalable structures which fit the 5G applications. Based on the vision proposed here, a dual-band and a tri-band structures were built and characterized by their main parameters. Both prototypes achieved peak efficiencies around 80%, with adequate bandwidths and gains, as well as great compactness.

Pass Through

The main factors involved in the design of anti-kickback fingers is in the contact angle at the point of contact with the wood, the radius of wear at this point, and the roughness of the wood with which it comes in contact. Because of the wide range of wood thicknesses that pass through a machine, conventional single-point fingers cannot come in contact with the wood at angles appropriate for each of these thicknesses. The use of many points ensures that a suitable contact angle is achieved for all thicknesses of wood for each machine. The results of two anti-kickback finger design projects, one for a machine in the furniture industry and the other for a machine in a sawmill resulted in a new analytical design method for efficient multipoint anti-kickback fingers. This new approach, as opposed to the conventional graphical method, was validated by comparing three specific cases; the advantages of the new method are illustrated in an example of the redesign of multipoint anti-kickback fingers.

Definition Of

In accordance with V. F. Sidorenko, ‘Canon-culture’ is ‘negative definition of Design’, because the Design always produces new forms and breaks the Canon. However the fact that the Design is always strives for new forms as a rule becomes the cause of superficial understanding of own traditional culture among designers. In turn it leads to loss of cultural identity what we can see in design in our country. The purpose of the article is to trace ‘positive’ connection between the Design and the Canon by the example of Japanese interior. We believe that it will help us to find deeper cultural meanings for design objects. At first we research the fundamental principle of Japanese art called ‘Shin – Gyo – So’. It is remarkable that this principle let transform the Canon within the Canon. Then we research the method called honka-dori, which, on the one hand, is rooted in traditional culture, in poetry, but, on the other hand, in the 20th century it was reconsidered and transferred in contemporary ‘traditional’ interior. After all we research design method of interpretation of the Canon. We called it the method of ‘internal of similarity’, because it let follow traditional aesthetics without of ‘cites’ of traditional forms. We suggest that it is this method which gives us ‘positive’ connection between the Design and the Canon. Although this method brings partial loss of cultural meanings, by the example of Japan we can conclude that the principle of ‘Shin – Gyo – So’ as well as the method of honka-dori can be used in contemporary design.

A new product configuration design method based on extensible product family is presented in this paper. The extensible product family is a multi-layered model with extensible function, extensible principle, and extensible structure. Treating extensible element as a basic unit, the model can be used to associate extensible parts with reusable factors in the range from 0 to 1. The principle of configuration method has been implemented in software. Complicated rule editing and modification are handled by Ch, an embeddable C/C++ interpreter. Designers can establish and edit the configuration rules including formulas dynamically. According to the client requirements and nearest-neighbor matching, the results of the designed configuration can be obtained automatically. Furthermore, the multi-dimensional information about parameters and reusable factors can be displayed and analyzed graphically. If the client requirements or configuration rules are changed, the system can be easily re-configured to obtain designed results based on the new configuration quickly. The system has been successfully deployed and used to design complicated products with a large number of configurations and different specifications such as elevators, machine tools and smut-collectors.
