Definitions

  • the invention relates to a method and apparatus for product design evaluation.
  • evaluation is also to be understood as exploration, which means that it is possible to assess the product design in an interactive manner.
  • the term 'pattern' also includes the use of, possibly, a logo or brand name as well as a representation of a label.
  • the model itself is usually of a light colour or white.
  • a projector that derives the images from data stored in a computer memory such as materials, patterns and colour images that have been obtained, for example, photographically or artificially by means of computer generation.
  • the drawback of the known method and apparatus is that the setup to be used is in fact a setup on laboratory scale, which is not portable. As a consequence, the known method and apparatus are very much tied to the location of the setup where the evaluation assessment can be performed.
  • the object of the invention is to provide a method and an apparatus that are not tied to the location of the setup, allowing the evaluation assessment to be simply moved to locations better suited to the availability of members forming the evaluation team or to accommodate other reasons that could make it desirable for the evaluation location to be flexible.
  • the characterizing feature of the method is that the model is positioned on a worktop and that during the projection of the image onto the model backlighting is provided to illuminate the model from a side towards which the light beams are directed, so as to visualize the model with the image projected thereon in the form in which it is placed on the worktop, without the image formation suffering distraction caused by background participation.
  • the invention is based on the insight that the image projected onto the model does not continue into the background of the model but, owing to the backlighting, falls away. This affords the advantage that to realise the desired projection on the model, no information is required concerning the model's position or shape.
  • the projection is preferably carried out with light beams that pass substantially over and along the worktop.
  • This horizontal projection of the images onto the model forms the basis for the flexible setup that characterizes the apparatus according to the invention.
  • the apparatus for carrying out a method of product design evaluation which is performed using a projector for the illumination of a model of a product design to be developed, and is provided with a control organ for the projector, wherein the projector is designed for providing light beams that form images of a material and/or pattern or colour for the model that are to be evaluated, is characterized in that a source for backlighting is provided illuminating the model from a side towards which the light beams are directed, such that the model with the image projected thereon can be observed in the form in which it is placed on the worktop without the image formation suffering distraction caused by background participation.
  • control organ for the projector usually embodied as computer, may be provided with images of the materials, patterns, or colours to be projected in the manner known from the prior art.
  • the apparatus is characterized in that the control organ for the projector is information-receptively coupled with an information source that may or may not be positioned at a distance and, for example, coupled via internet and selected from the group comprising a digital data carrier, a computer, a camera.
  • an information source that may or may not be positioned at a distance and, for example, coupled via internet and selected from the group comprising a digital data carrier, a computer, a camera.
  • the drawing shows an object or model 2 placed on a worktable 1, serving as example for the product design evaluation.
  • the model 2 is illuminated with a projector 3, which in the case illustrated is suspended from the table 1 by means of a fastening construction 5, and which via a mirror 4 projects a material and/or pattern or colour image onto the model 2.
  • a projector 3 which in the case illustrated is suspended from the table 1 by means of a fastening construction 5, and which via a mirror 4 projects a material and/or pattern or colour image onto the model 2.
  • the use of the mirror 4 achieves that only the model 2 is visible on the worktop and elements such as the projector that distract from the image formation, can remain outside the picture.
  • the mirror 4 is positioned such that the projection of the image onto the model 2, at least the portion ending at the model 2 and passing over the worktop 1, occurs with light beams that substantially pass above and over the worktop 1. Attention is drawn to the fact that a source 10 for backlighting is provided, which illuminates the model 2 from the side towards which the light beams are directed.
  • the projector 3 is coupled with a control organ 9, usually in the form of a computer.
  • this computer 9 is information-receptively coupled with a camera 6, which camera is mounted on either another or the same table by means of a swivel arm 7, and with which an image may be obtained from a sample material 8, whose texture, the pattern or the colour is projected onto the model 2 via the computer 9 and with the aid of the projector 3.
