Solution Overview

Problem

Drivers face challenges in intuitively understanding the influence of the travel environment, such as wind, on their vehicle, which existing technologies have not effectively addressed.

Innovation Solution

A vehicle display device that projects virtual images onto the windshield, using sensors and prediction algorithms to display wind direction and speed in a visually intuitive manner, including animations and icons to alert drivers of potential hazards and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If conventional wind direction display methods are used, then wind information can be displayed, but the driver cannot intuitively understand the influence of wind on the vehicle

Engineering Contradiction:
Improvewind influence understandingVSAvoidintuitive comprehension
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent creates a virtual image that copies and visualizes the invisible wind force acting on the vehicle. The display figure replicates the wind's directional and intensity characteristics in a visually perceivable form, allowing drivers to intuitively grasp wind influence without complex data interpretation

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent employs color variations in the display figure to represent different wind conditions. The display figure changes color based on wind speed and direction, providing immediate visual feedback about wind intensity and helping drivers quickly assess the impact of wind on vehicle stability

Inventive Principle:
Principle #32Color changes

2Loss of information

If detailed weather information is displayed, then comprehensive environmental data is provided, but the display becomes complex and hard to interpret quickly

Engineering Contradiction:
Improveenvironmental information completenessVSAvoiddisplay complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent extracts only the most relevant wind information (direction and intensity) from comprehensive weather data and presents it through a simplified display figure. By isolating and visualizing only the critical wind parameters that affect vehicle stability, the system maintains information completeness while reducing display complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms abstract weather data into a spatially oriented visual representation. The display figure is positioned and oriented in the display area to correspond with the actual wind direction, adding a spatial dimension that makes the information immediately interpretable without complex processing

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
