The delineated approach provides an educational concept for Collaborative Product Development. It aims at teaching and training skills to accomplish collaborative product development projects as the head of the team as well as a team member. Attention is especially paid to heterogeneous teams of different skills, knowledge, specialization, ambition, location as well as cultural background. As Collaborative Engineering aggravates the definition of structures the proposed approach ceases from the common focus on curriculum-driven education. Instead, the approach incorporates principles of active learning, an approach developed in the early 90s, for exercises. Whilst base knowledge is imparted by means of conventional frontal instruction lectures, the according skills are trained in line with exercises lessons encouraging active participation. A novel exercise concept has been developed to cope with the challenges raised by Collaborative Engineering. This concept stipulates a realistic simulation of a collaborative product development environment. For that purpose, cooperation among the Institute for Engineering Design, RWTH Aachen University, Germany and the Mechanical & System Design Engineering (MSDE) Department as well as the Industrial Design Department, both of Hongik University, Korea has been established. Students from the three departments participate in cooperating project teams to develop a certain product. During the project, the lecturers just assist as consultants, acting if explicitly asked for help by the students. It is intended to let critical situations emerge as under realistic conditions, so the students learn by first hand when and how certain techniques can be applied.

Plain and simple, a corrugated cardboard box(CCB) provides the right level of protection for goods in transit, which helps keep shipping costs down. As made mostly from trees, a renewable resource, corrugated cardboards are processed and also recycled into paper products and even new boxes. CCB come in a number of shapes and sizes. From regular slotted, squared-shaped containers, to full telescope designs for fragile items, there are a variety of styles to choose from. Moreover, thanks to the material’s durability, many corrugated packages can be reused multiple times before they even hit the recycle bin. The research provides an appropriate tool aid that makes the eco-friendly corrugated packaging to suit specific product shipping needs for the environment with no glues or extra binding material at all.

The activities for the development of STEP-NC, a new STEP-compliant data model for the NC controllers, have been started since 1998, and recent tests showed that the new process chain allows savings of about 20% of total machining cost. The primary goal of the paper is to develop a 'data model', which can be a foundation for the exchange of product data in rapid prototyping(RP) as the one among STEP-NC modules. User requirements have been collected and analyzed in order to formulate a basis for the RP data model that is expected to be a functional model for estimating time and cost for part fabrication.

In-line skate generally consists of four major parts: boot, frame, bearing and wheel, and the most important part among those for necessary functionality is the frame. It is the most expensive, and it also makes a decisive role in practical race skating. The functional behavior of a frame is greatly affected by external dynamic forces as well as the static weight of a skater. We are proposing a new inline speed-skating frame design that has been improved in structural strength and weight for providing optimum speed in 20-40km marathon skating.

Direct Metal Deposition (DMD) is a new additive process producing three-dimensional metal components or tools directly from CAD data, which aims to take mold making and metalworking in an entirely new direction. It is the blending of five common technologies: lasers, CAD, CAM, sensors and materials. In the resulting process, alternatively called laser cladding, an industrial laser is used to locally heat a spot on a tool-steel work piece or platform, forming a molten pool of metal. A small stream of powdered tool-steel metal is then injected into the metal pool to increase the size of the molten pool. By moving the laser beam back and forth, under CNC control, and tracing out a pattern determined by a computerized CAD design, the solid metal part is eventually built line-by-line, one layer at a time. DMD produces improved material properties in less time and at a lower cost than is possible with traditional fabrication technologies.
