Marker Display Device for Vehicle Speed and Engine Regime Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices fail to indicate an incorrect correlation between instantaneous speed and engine operation regime in motor vehicles, lacking the ability to detect abnormal operation without technical knowledge.
Innovation Solution
A marker display device with a controller communicating with measuring and referencing devices to align or misalign indicators on graduated scales based on normal or abnormal operation, providing real-time audio-visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single device indicator provides simultaneous information on vehicle speed and engine operation regime, then information density is improved, but the ability to detect abnormal operation deteriorates
Solution Approach 1:
The patent divides the information display into two separate graduated scales (first scale for vehicle speed, second scale for engine operation regime) instead of using a single combined indicator. This segmentation allows each scale to be independently evaluated against its corresponding indicator, enabling the detection of abnormal operations when the indicators do not align, while still providing comprehensive information on both parameters simultaneously.
2Loss of information
If multiple graduated scales are displayed on the same display screen, then information completeness is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges multiple graduated scales (first scale for vehicle speed, second scale for engine operation regime) onto a single display screen, allowing both parameters to be displayed simultaneously in one location. This combining approach provides complete information on multiple parameters without requiring separate physical displays, thereby reducing overall system complexity while maintaining information completeness.

AI summary
A marker (15, 16) display device for an electromechanical device including at least two scales (11, 12) on which a plurality of markers (15, 16) are distributed, respectively linked to the values of physical magnitudes corresponding to at least a first and second physical magnitude linked to each other and relative to the operation of an electromechanical device; a first and a second indicator (13, 14) are adapted to indicate a value associated with the first and second physical magnitude, respectively, both indicators being aligned on aligned markers (15, 16), belonging to a first and a second graduated scale (11, 12) during the normal operation of the elements of the device assembly.
