    Development of code-marking equipment for logs2004In: PROCEEDINGS OF NORDDESIGN 2004: PRODUCT DEVELOPMENT IN CHANGING ENVIRONMENT / [ed] Lehtonen, T, TAMPERE: TAMPERE UNIV TECH PRODUCT DEVELOPMENT LABORATORY , 2004, 201-210 p.Conference paper (Refereed)
    Abstract [en]

    This paper gives an overview of the product development process applied to development of code-marking equipment for logs. The learning and decision making process during the development is showed. Also the situations when a decision had to be made without having sufficient amount of information are described. The development of a log code-marking equipment for a log sorting station in a sawmill is described retrospectively, but the development of a code-marker for harvester mounting is described as in real time. In the latter case the conditions for code-marking on-board forest machines are discussed and different possible solutions are described and evaluated but the final decision is left open. So it is possible for every reader to make his own decision. This product development process shows that in a specific case it is not only difficult to generate good concepts, it is also difficult to decide, evaluate and guess whether the concept is viable, would it work in a real environment and is it robust enough? This question appears especially when the product will be created in the field where no solution exists. Finally it is concluded that in this product development process the discovery of new ideas in concept generation is strongly motivated by the need for them, when it is realised that the available concepts/solutions do not work, then there exists much stronger motivation for finding new concepts. This is an iterative process, with several loops.

    Development of code-marking equipment for logs - Sensitivity of fluorescent code-mark for log marking environment2004In: Proceedings of the 4th International Conference of DAAAM National Estonia / [ed] Papstel, J; Katalinic, B, TALLINN: DAAAM NATIONAL TALLINN, TALLINN TU , 2004, 78-81 p.Conference paper (Refereed)
    Abstract [en]

    This paper describes the readability of fluorescent paint marks for the development process concerning code marking of logs using automatic vision systems. The result indicates that using fluorescent point is a technique with many advantages e.g. offering the possibility to be read under ice. An imprint marking technique was tested in the recently finished European Community LINESET project. One disadvantage of using paint instead of the imprint technique is the cost of paint. Another is its sensitivity to weather conditions during marking, but the paint is much better discernible for a vision system than the imprint code-mark also the mechanical constraints at paint marking are lower than at the imprinting.
