Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle instrument panels with dual-scale gauges, such as speedometers, face visibility issues due to low illumination uniformity and difficulty in recognizing driving speed, especially in daylight or sunny conditions, as a result of multiple light sources required for each scale.
Innovation Solution
A vehicle instrument panel with a three-dimensional illumination effect, featuring a transparent ring with primary and secondary scales, a reflecting plate to redirect LED light, and a prism unit to reflect light towards the scales at a predetermined angle, minimizing the number of light sources while enhancing visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are disposed corresponding to respective scales to improve illumination uniformity, then illumination uniformity is improved, but the number of light sources increases
Solution Approach 1:
The patent merges multiple light sources into a single LED located at the center of the transparent ring. This single light source illuminates all scales uniformly through the transparent ring structure, eliminating the need for multiple separate light sources while maintaining illumination uniformity across all scales.
Solution Approach 2:
The single LED light source serves multiple functions by illuminating all scales simultaneously through the transparent ring. The transparent ring acts as a universal illumination medium that distributes light to all scales, making one light source perform the work of multiple light sources.
2Loss of information
If two different scales are arranged in a dual-scale gauge, then information display is improved, but visibility is reduced
Solution Approach 1:
The patent applies local quality by forming scales with different depths on the transparent ring. Primary scales are formed at a first depth while secondary scales are formed at a second depth, creating distinct visual layers that improve visibility and prevent confusion between different scale readings while maintaining comprehensive information display.
3Illumination intensity
If scales are formed on a transparent ring with three-dimensional shape, then visibility and stereoscopic information are improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs spheroidality by using a transparent ring with a three-dimensional circular shape. The curved surface of the ring naturally provides stereoscopic depth perception and enhanced visibility. Scales are formed on this curved surface at different depths, creating a three-dimensional display effect that improves driver perception of speed and other measurements.

Implementation Method 1
a reflecting plate for changing a direction of travel of LED light, generated below the transparent ring, to travel along the transparent ring in clockwise and counterclockwise directions
Implementation Method 2
a prism unit including at least one prism for reflecting a portion of the LED light traveling along the transparent ring toward the at least one primary scale at a predetermined angle
