Solution Overview

Problem

Existing vehicle information systems fail to effectively and intuitively convey danger information to drivers without causing discomfort, as they often do not clearly indicate the presence or absence of danger around the vehicle.

Innovation Solution

A vehicle information transmitting device that uses a display device with a safe region frame and a vehicle state display figure, controlled by a lighting unit to intuitively convey danger information by changing the display position, size, and color based on detected dangers, ensuring the driver understands the situation without feeling bothered.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If danger information is displayed prominently to ensure driver awareness, then information transmission effectiveness is improved, but driver comfort deteriorates due to potential distraction or discomfort

Engineering Contradiction:
Improvedanger information transmissionVSAvoiddriver comfort
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent applies local quality by displaying danger information in specific localized regions of the display device rather than uniformly across the entire display. The control unit selectively positions danger information in peripheral regions when danger is detected, while maintaining normal display content in central regions, thus providing targeted information without overwhelming the driver.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements dynamics by making the display position adaptive based on detected danger conditions. The control unit dynamically adjusts the position of danger information display based on the detected danger direction, transitioning from static central display to dynamic peripheral display only when and where needed, balancing information delivery with driver comfort.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If display area is moved to indicate danger direction, then danger information clarity is improved, but display stability deteriorates due to frequent position changes

Engineering Contradiction:
Improvedanger direction indicationVSAvoiddisplay area position
Core Design Contradiction:
Loss of informationVSStability of the object's composition

Solution Approach 1:

The patent applies dynamics by making the display position conditional and adaptive. The display area remains stable in normal conditions but dynamically shifts to peripheral regions only when danger is detected in specific directions. This conditional dynamics maintains stability while providing clear directional danger indication when necessary.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the display area into functional zones: a stable central region for normal information display and dynamic peripheral regions for danger information. This segmentation allows the central display to remain stable while peripheral areas provide directional danger indication, reducing the overall impact of position changes on display stability.

Inventive Principle:
Principle #1Segmentation

AI summary

To provide a vehicle information transmitting device capable of transmitting information associated with danger at a periphery of the own vehicle in a manner intuitively understandable by the driver. In the present embodiment, when a dangerous direction is the left or the right, a display position of an own vehicle state display figure 10c is changed from a display position in an initial state to a display position on the same side as the dangerous direction. If the dangerous direction is on the front, the display position of the own vehicle state display figure 10c is changed from the display position in the initial state to a display position on an upper side. When a dangerous target is detected, a display area of the own vehicle state display figure 10c is changed to a display area greater than the display area in the initial state. Furthermore, when the dangerous target is detected, a display color of the own vehicle state display figure 10c is changed from a display color in the initial state to a display color in the danger information display state.
