Vehicle Speed Display With Dynamic Visual Emphasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle speed displays do not effectively differentiate between relevant and non-relevant speed values, making it difficult for drivers to quickly identify critical speed parameters.
Innovation Solution
The vehicle employs dynamic reproduction means that adjust the size and color of speed displays based on current parameter values, with detection systems considering various state parameters like ambient brightness, weather, equipment, and road conditions to emphasize relevant speeds or parameters, such as flashing or changing colors and font sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform format is used for displaying all speed values, then display consistency is maintained, but relevance differentiation is lost
Solution Approach 1:
The patent applies local quality by making different parts of the display have different visual properties. Specifically, certain speed values are highlighted with increased font size, bold formatting, or color changes based on their relevance to the driver (e.g., speed limits, current speed), while other speeds maintain the standard uniform format. This allows the display to be uniformly structured overall while providing localized visual emphasis where needed.
2Loss of information
If dynamic parameter adjustment is implemented, then relevance recognition is improved, but system complexity increases
Solution Approach 1:
The patent implements parameter changes by dynamically adjusting visual parameters (font size, color, boldness) of displayed speed values based on their relevance. The allocation means evaluates each speed value against stored reference values (such as speed limits, maximum permitted speeds, or driver-defined important speeds) and modifies the display parameters accordingly. This allows critical information to stand out without requiring complex additional hardware.
Solution Approach 2:
The patent uses copying by creating visual copies or representations of the speed values with modified properties. Rather than displaying all speeds identically, the system generates visual variants of the numerical display with different emphasis levels. These copied representations maintain the same fundamental information but differ in visual prominence, allowing the driver to quickly identify relevant speeds without adding physical display elements.
3Reliability
If visual emphasis is added to critical speeds, then driver awareness is enhanced, but display uniformity is reduced
Solution Approach 1:
The patent applies color changes as a visual emphasis mechanism. Critical speed values such as speed limits or currently exceeded speeds are displayed in distinct colors (e.g., red for exceeded limits, yellow for approaching limits, green for normal operation) compared to standard speeds. This color-coding system enhances driver awareness of critical parameters while maintaining a systematic and organized display format.
Solution Approach 2:
The patent implements dynamics by making the display format adaptive rather than static. The visual emphasis applied to speed values changes dynamically based on the current driving context, the relationship between current speed and reference speeds, and potentially environmental factors. This dynamic adjustment ensures that the most relevant information is always emphasized while allowing the display to return to uniformity when no critical speeds are present.
