Vehicle Display Device Speed Deviation Scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for vehicles do not effectively facilitate the driver's understanding of deviations from speed limits, which can lead to unsafe driving practices.
Innovation Solution
A display system that includes a liquid crystal display unit showing the current vehicle speed and the deviation from the speed limit using a scale display, allowing drivers to easily grasp the difference through numerical or graphical representations, encouraging safe driving by promoting adherence to speed limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display system shows only the current running speed, then the device complexity is reduced, but the driver cannot easily grasp the deviation from the speed limit
Solution Approach 1:
The display is segmented into distinct functional areas: a running speed display area showing current speed, and a deviation amount display area showing the difference from the speed limit. This segmentation allows each area to present specific information clearly, making it easy for the driver to grasp speed deviation without overwhelming complexity
Solution Approach 2:
The patent adds a new dimension to the display by showing not only the current running speed but also the deviation amount from the speed limit. This dimensional expansion transforms a single-value display into a comparative display that provides context for safe driving decisions
2Measurement precision
If the display system uses numerical difference values, then the information is precise, but the driver cannot intuitively grasp the deviation ratio
Solution Approach 1:
The patent transforms the deviation information from absolute numerical difference to a ratio parameter. By displaying the deviation amount as a ratio relative to the speed limit, the system maintains measurement precision while improving intuitive understanding. The ratio format allows drivers to quickly assess whether they are approaching or exceeding the speed limit

AI summary
A display system is a display system which is installed in a vehicle and includes a liquid crystal display unit which outputs information representing a deviation amount of the current running speed of the vehicle from a speed limit set for an area where the vehicle is currently running.
