Starting Point

The importance of the concept development phase in product development is contradictory to the level and amount of current computer-based support for it, especially with regards to mechanical design. Paper-based methods for conceptual design offer a far greater level of maturity and familiarity than current computational methods. Engineers usually work with software designed to address only a single stage of the concept design phase, such as requirements management tools. Integration with software covering other stages, e.g. functional modeling, is generally poor. Using the requirements for concept models outlined in the VDI 2221 guideline for systematic product development as a starting point, the authors propose an integrated product model constructed using the Systems Modeling Language (SysML) that moves beyond geometry to integrate all necessary aspects for conceptual design. These include requirements, functions and function structures, working principles and their structures as well as physical effects. In order to explore the applicability of SysML for mechanical design, a case study on the design of a passenger car’s luggage compartment cover is presented. The case study shows that many different SysML diagram types are suitable for formal modeling in mechanical concept design, though they were originally defined for software and control system development. It is then proposed that the creation and use of libraries defining generic as well as more complicated templates raises efficiency in modeling. The use of diagrams and their semantics for conceptual modeling make SysML a strong candidate for integrated product modeling of mechanical as well as mechatronic systems.

The energy consumption and environmental impacts of a product are largely determined during concept design. It is the core for energy saving product development to integrate energy saving into product concept design process. In this paper, a framework for energy-saving product concept design based on TRIZ/function analysis is proposed, the energy flow chart is built based on the analysis of product function. By eliminating the harmful function associated with energy and environment, resolving the conflict parameter and attributes of components in energy and function, the new product that satisfy user needs while minimizing energy consumption is obtained. A case study is also presented to illustrate the effectiveness of the proposed design framework.

The purpose of this paper was to make people aware of the new concept design of the food court that influence the ambiance and related to the attractiveness factors. The method of documentation of the interior element was done by the analysis to the food court in Senayan City. It was expected to be a comparison of the previous design before the renovation (Food Studio) in connection with the modernization and renewal of the design (Delicaè). Some design elements such as floor wall and ceiling that applied must bear a lasting impression and be an inbuilt piece of the decoration that linked to scale, style, and color. This research was potentially contributed to shopping malls attractiveness factors and their impact on shoppers’ satisfaction in shopping malls in Jakarta and outside the city. It can be concluded that updating the design is very important if the shopping malls do not want to left-behind in this modern area. The comparison has been made between old-design with the new one that is found out that people nowadays are very open-minded about design and do care about attractive things in shopping malls.

AbstractTopological optimization (TO) is commonly used to design a part for additive manufacturing (AM), but rarely for entire systems including several parts. How can be optimized a mechanical system in which each optimized part changes the boundary conditions? A Design method called TOMS (Topological Optimization of a Mechanical System) has been developed to take into account the variation of the boundary conditions when optimizing parts. When the using TOMS method the loops are performed until the optimization converges. The object of this article is to propose a discussion on the quantification of this convergence based on a practical case study.

Footwear Comfort

Advanced technologies for modelling and production are an important part in the whole process of product manufacturing. These advancements have changed the way of product development and play an important role in customization. In the footwear industry, as in any other industry, the use of these technologies is widely spread. Footwear comfort is one of the main selection criteria for purchase. Considering this fact, a case study of different steps for shoe designing according to individual foot shape will be presented. Taking into consideration the aesthetics of the sole and in a more sustainable view, through topological optimization reducing of material wastage for sole production will be presented. By means of the topological optimization in the shoe design process, sole optimization is realized. As a part of personalization, feet’s plantar pressure maps taken from 1 participant gave a better explanation of weight distribution of each foot. Following, sole personalization according the plantar pressure maps for each foot gives the possibility to obtain the best least material design according to the feet’s pressure while maintaining biomechanical performance.

This paper presents a methodology called ‘Design for Fixturability’ (DFF). This methodology enables designers to perform manufacturability analysis of their product designs upfront into the design process. The DFF approach provides a mapping between parametric representation of a part design and fixturing capability of a facility and presents a methodology to evaluate the design with respect to the fixturing capabilities. The methodology is applicable to the mass-production commodity parts and part families, which typically require dedicated manufacturing facilities. A prototype DFF system for connecting rods of an automotive engine is developed. The system enables the designers to design the connecting rods by considering the fixturing (datums) capabilities of existing manufacturing facilities during the concept design stage, when design parameters are still not frozen. The DFF system analyzes the design with respect to fixturing capabilities of facilities and generates suggestions for the designer, to modify his design if required.

Puh Sarang Church which located at Kediri, East Java, Indonesia, who’s made by Henri Maclaine Pont, give an illustrated of case study, how the Church developed with a good and great idea from the Architect which his effort to revitalized a local mind (intelligence) and then to transformed in a new form (modern form), but it is still hold on a local paradigm. The Puh Sarang Church in Kediri is different with any church form that build in Java (in that time) which some Church architecture and interior design a propose from Europe. Besides make use of local potency, Puh Sarang Church shown the impression of a sustainable product, because all of the transformation which Henri Maclaine Pont has already happens, he still use the natural paradigm became prime element for the design and the development. The aim of this paper is want to show if the architectural and interior design’s product done with use local paradigm in the concept, design, and carried by material, new technology is effort revitalization and transformation architecture and interior design as a holistic and comprehensive thinking.
