Conservation of this art has always been accorded priority. Several instances have been reported of a craft’s lineage having died out because there being very few craftsmen willing to continue practicing or train new interns. Continuing the family traditions is becoming difficult besides resulting in documentation gaps and tacit knowledge loss. Designers need efficient methods to capture and document a craftsman or a fine artists or a designers’ mental model not only during creation but also during reflection and conservation. This paper outlines a method and process to identify components of tacit knowledge within Implicit and Explicit knowledge categories of a crafts object. Craftsman engaged during the creation of the objects are observed and documented. Using ethnography and personal interviews, their activity is analyzed to derive and categorize components of knowledge. It is posited t...

It is due to the fact that most of the jobs which require manual editing, drafting, designing and modeling have been easily done with the help of the computers. Slowly the shifts have been seen from traditional manual methods to modern-day technological advance computer systems. In this shift the traditional knowledge of the practitioner is getting lost. This can be seen in variety of industries like craft, jewelry, art and agriculture. The people engaged in these industries are seeking certain alternative ways to achieve this traditional knowledge. Previously this traditional knowledge was achieved by practicing with the master which is now achieved using modern technologies and computers. Capturing this tacit knowledge has been one of the major objectives of this ongoing work. The transfer of knowledge from the master craftsmen to the learner takes place with several days of practice. Natural language plays an i...

Design matrix focuses more on the measurement of innovation. The positive effects of introducing design matrix are validated through the final prototypes of the three design solutions. The first one involves users who are making different envelopes of various sizes. The second case study involves making of paper bags of standard size. The third case study involves the same set of users making office files. The paper attempts to validate the applicability of Design Matrix to three product case studies. At first glance the problems chosen are very simple but when seen from User’s point of view and by using a matrix—innovation is attempted to be measured. The authors contend that Innovation need not necessarily mean complex thinking or solving complex problems. The paper concludes with proposing future application of processes Design Matrix for complex products.

The slow depletion of the crafts culture has been a concern to the researchers. Craft products are being replaced by alternative plastic products. This has depreciated the skills involved in the making of the craft products. An attempt has been made to digitally represent the knowledge embedded in craft objects as well as its roots in the craftsman involved. Knowledge, which is embedded in the craft object, is captured digitally. The paper attempts to answer two basic questions: Is it possible to capture the tacit knowledge of the craftsman in a digital format? If so, how can this knowledge of the craftsman be represented and used in designing more craft products in design? The outcome is in the form of a fuzzy model, which binds the knowledge/skills of the craftsman embedded in his creation. The proposed fuzzy-based model accesses craft products in terms of various design eleme...

The framework combines activities (Generate, Evaluate, Modify, Select: GEMS), outcomes (State change, Action, Parts, Phenomenon, Input, oRgans, Effect: SAPPhIRE) and co-evolving requirements and solutions (req-sol). The framework is divided into two stages: Requirements Exploration Stage (RES) and Solutions Exploration Stage (SES), and allows detailed exploration of the outcomes for requirements and solutions. IDEA-INSPIRE is a computer-based tool that suggests analogically relevant solutions from a database of natural and engineered systems, to support idea-generation during the early stages of designing. Four major requirements were identified for the mobility system: mobility, handling gradient, stability and steering. A variety of ...

The paper provides a theoretical model for the obstacle climbing ability of the vehicles, where an obstacle is defined as a step. A model of each vehicle is developed using Lego-Mindstorms TM toolkit, and experiments are conducted to find the maximum heights and the maximum slopes climbed by each vehicle. It is found that the TTV has a substantially better obstacle climbing ability than Shrimp III – the existing robot with the best climbing performance. The results compare well with the theoretical models.

The one dimensional configuration of NWs poses a challenge for efficient doping due to the large number of surface states pinning the Fermi level close to the middle of the band gap and thus creating a large depletion layer at the surface. This effectively reduces the effective volume for doping. However, the flexibility of different architectures offered by the NWs, in particular, the core–shell configuration along with different growth mechanisms associated with the core and shell can be strategically used for efficient doping. In this work, the authors report on a catalyst free Ga-assisted approach for the growth of Be-doped GaAs NWs by molecular beam epitaxy. A systematic and a comprehensive study is reported using a variety of characterization techniques to determine the impact of NW configuration, Be cell temperature, and V/III beam equivalent pressure (BEP) ratio individua...

GEMS of SAPPhIRE as req–sol, a systematic framework for designing and Idea–Inspire, a computational tool to assist ideation respectively provide process and product knowledge. The support has been applied in an industrial project for designing novel concepts for a lunar vehicle mobility system. One of the concepts is chosen for physical and virtual modelling and testing. The support has ...
