Solution Overview

Problem

Existing head-up displays in vehicles often irritate drivers as the displayed content can overlap with objects in the driver's field of view, making it difficult to distinguish critical objects like pedestrians or obstacles from the displayed information.

Innovation Solution

A method for controlling a transparent display in a vehicle's windshield that captures sensor data to determine the color and position of objects in the environment and dynamically adjusts the display content's color to ensure that critical objects are easily distinguishable from the displayed information, using a combination of cameras and potentially other sensors to estimate object trajectories and properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If content is displayed in the windshield using head-up display, then information is presented to the driver, but the displayed content may overlap with objects in the driver's field of view causing irritation and difficulty in distinction

Engineering Contradiction:
Improveinformation presentationVSAvoidvisual confusion
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies color changes by dynamically adjusting the color of displayed content based on the detected color of objects in the environment. When an object is detected, the system changes the color of the displayed content to contrast with the object's color, making the object stand out and reducing visual confusion between displayed information and real-world objects

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent implements parameter changes by modifying the color parameter of the displayed content based on sensor data about the environment. The control unit changes color parameters dynamically according to detected object characteristics, ensuring optimal visual distinction between displayed information and surrounding objects

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the displayed content uses fixed color, then the display system is simple, but the driver cannot easily distinguish critical objects from displayed information

Engineering Contradiction:
Improveobject distinctionVSAvoiddisplay control
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements feedback by using sensor data about the environment and detected objects to dynamically control the color of displayed content. The system continuously monitors the environment, detects objects, and adjusts display parameters accordingly, creating a closed-loop control system that adapts to changing conditions

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies dynamics by transitioning from fixed color display to dynamic color adjustment. The displayed content color changes automatically based on real-time detection of objects in the environment, allowing the system to adapt to varying driving conditions and maintain optimal visibility

Inventive Principle:
Principle #15Dynamics
