Abstract

The designs of the instruments of modern cars are often full of different scales and status or warning lights. Due to the limited space where all of those have to be placed, the options for different designs are very limited. Up to now there are a few ideas that help reducing the number of lights and give space for different arrangements of the instruments. For example the pointers for speed or the fuel gauge can be illuminated by LEDs (Light Emitting Diodes) of different colors, as shown in figure 1, to save warning lights for high speed or low fuel.

Combination Meter Construction

Idea: Kenichi Takato, DE-Babenhausen

The designs of the instruments of modern cars are often full of different scales and status or warning lights. Due to the limited space where all of those have to be placed, the options for different designs are very limited.

Up to now there are a few ideas that help reducing the number of lights and give space for different arrangements of the instruments. For example the pointers for speed or the fuel gauge can be illuminated by LEDs (Light Emitting Diodes) of different colors, as shown in figure 1, to save warning lights for high speed or low fuel.

It is now proposed to use pointers that are placed behind the dials and are illuminated in various colors in a different way. As shown in figure 2, using pointers that are behind the scales, and therefore longer, saves space inside the dials where digital displays or status lights can be placed. The color of the pointers is changed by colored printings behind the dials. The pointer itself is lit up by white LEDs and then lights up that small part of the printing it is behind. This principle is shown in figures 3 and 4. The advantages are not only that this combination saves space and lights, but it is also cheaper and makes free designs possible since designers have more possibilities to arrange the different gauges.
