Abstract Conventional multiband antennas suffer from strong interactions among different operating frequencies, complex configurations, low bandwidth, and reduced efficiencies. A design concept for a multibeam multiband antenna in wireless devices is proposed in this paper. The design concept provides a promising approach to augment transmission and reception. The principle of design involves a primary radiating element embedded in a triplate conformation which excites a passive array of multiple frequency secondary radiators, forming a frequency selective structure in triplate (FSST). The higher order mode behavior of the parent antenna characterizes the design of FSST placed in its nearfield. The mathematical modeling and analysis of the design methodology is also presented. As proof of concept, the proposed design methodology is validated with simulations and experiments at four unlicensed communication bands and the results are compared.

Recently, bicycles are used as exercising machines and traffic vehicles. Planetary gear trains can be used as the transmission systems with multi-speed for bicycles. The purpose of this work is to propose a design methodology for the design of eight-speed internal gear hubs with planetary gear trains for bicycles. First, we propose a design concept for the design of eight-speed planetary gear hub. Then, based on this design concept and train value equation of planetary gear train, the kinematic design of eight-speed planetary gear hub is accomplished. One eight-speed planetary gear hub is synthesized to illustrate the design methodology. Based on the proposed design methodology, many eight-speed internal gear hubs with planetary gear trains can be synthesized.

Concept Application

To raise the market competition ability of the civil helicopter, it is required to have high technical content in RMS including reliability, maintainability, safety, supportability and testability for the new generation civil helicopter. To meet the requirements of the civil helicopter, it is decided to follow strictly the maintenance matrix from the preliminary design phase of the transmission system. To decrease the maintenance cost, the structure will be optimized during the detail design phase and checked by DMU (Digital Mockup) in VPM (Virtual Product Model) system. And to get the high safety and reliability, some advanced design technical are applied and substantiated by some new test methods. This paper explains design concept application on RMS for tail drive system of the civil helicopter by showing some practice for an example. It can provide the method and reference for the development of civil helicopter transmission system.

The Way

Abstract Students at three graduate schools of mechanical engineering and adult groups in Japan have been taking conceptual design courses the authors teach. Among the three graduate schools, the 24 hour course, at the University of Tokyo, spread over 13 classes during 4 months, takes the students all the way from identifying their design goals, generating ideas, refining their designs, to building prototypes. The adult course students also spend long hours of building prototypes. Despite strong encouragement by the instructors for detail design, the students often leave their design concepts at rough stages without refining their ideas to the detail level needed for prototype building. Building a prototype from a design concept that is not fully expanded often results in efforts that lead to failure and retrial. Such back and forth between concepts and physical trial is unavoidable in design, however, if possible they better be kept at the minimum. The instructors, in their efforts to better motivate students to refine the designs, developed a metric “Level of Readiness (LOR) index” for evaluating how refined a design is. Students are better motivated to reach higher scores and this index that evaluate the quality of their designs, in terms of how detail they are, in numbers serves as a better incentive for the students than words from the instructors.

In this paper a SysML navigation models and early design methodology is briefly introduced. The methodology is offering tool and pre-defined models for mobile robot design in early design stage. The main target is reaching the optimal and efficient conceptual solution for detail design stage by using the pre-defined and validated SysML models according to the robot purpose and missions. As an example a snow plowing mission is demonstrated. Real mobile robot platform called UKU is developed and used for model validation purpose.

Abstract A methodology is presented for automating or at least aiding a human designer in selection of a design concept for given design requirements. Futhermore the proposed methodology provides reasonable estimates for the various parameters of the design structure. This is accomplished by representing design requirements and design parameters as multidimensional vectors and performing appropriate interpolations to estimate feasible solutions.

Locks are important safety devices in our daily lives. The purpose of this study is to design new mechanisms of multipoint mortise locks based on a systematic approach. Firstly, the classification and advantages of mechanical locks are introduced, and the definitions and the development of mortise locks are described. Then, the multipoint mortise locks are decomposed into four sub-parts by the different functions, including the latch bolt lock, the dead bolt lock, the dead-latch bolt lock, and the connecting mechanism. The four sub-parts are further analyzed to conclude their structural characteristics as well as design requirements and constraints. Based on Yan’s creative mechanism design methodology, the concepts and the atlas of designs are synthesized systematically. One feasible mechanism is further chosen for detail design. Finally, a computer program for simulation is developed and prototypes are built for verifying the design results. The results of this study provide a valuable reference for designing multipoint mortise locks and for the analysis of mechanism characteristics of mortise locks.

The 1960S

This paper is not a comprehensive survey of the architectural career of Arata Isozaki, one of the most distinguished practicing architects in the world today and the 2019 winner of the Pritzker Prize, but a specific look at his formative years of the 1960s when he began to build his own design methodology. It delineates Isozaki’s encounter with the avant-garde art movement of the 1960s, collectively called “Anti-Art, ” against the backdrop of the “anti-spirit” of Japanese society. Although Isozaki’s artistic side has been overstated at times, previous studies rarely addressed how his intensive interactions with art circles played a role in shaping his design methodology. I would like to examine the convergence of creative individuals and cross-disciplinary connections to understand Isozaki’s architectural thinking.This study examines how Isozaki’s collaborations with his artist contemporaries enabled him to formulate the notion of the “invisible city, ” a radically new design concept characterised by the expansion of the nature of architecture from producing isolated built-forms to all-encompassing natural and manmade environments. However, after drawing on communications and information theory, which prevailed in 60s architectural circles, Isozaki’s destructive and anarchistic connotation of “invisible city” was channeled into a systematic cybernetic model and eventually transformed into a constructive planning method. I will discuss the realisation of a cybernetic environment at the Festival Plaza of Expo’ 70 and trace the legacy of “invisible city” in his later postmodern work.
