Solution Overview

Problem

Existing vehicle display systems, particularly those using wearable terminals, face challenges in effectively and appropriately displaying information to occupants, especially in terms of orientation and privacy, and fail to ensure that critical information like obstacles is not overlooked.

Innovation Solution

A vehicle display nexus control apparatus with a first display part at the vehicle main body and a second display part at a wearable terminal, where the display location is dynamically selected based on the type and priority of information, ensuring that critical information is displayed prominently at the wearable terminal and personal information is kept private, with the ability to prioritize and hide information as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If information is displayed at the wearable terminal (second display part), then information visibility in front of occupant's eyes is improved, but device complexity increases due to multiple display parts and control mechanisms

Engineering Contradiction:
Improveinformation visibilityVSAvoiddisplay system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The display system is segmented into two distinct display parts: a first display part at the vehicle main body and a second display part at the wearable terminal. This segmentation allows information to be distributed across multiple display locations, improving visibility and accessibility for occupants while enabling differentiated information presentation based on context and priority.

Inventive Principle:
Principle #1Segmentation

2Productivity

If display location is dynamically selected based on information priority, then information display effectiveness is improved, but control complexity increases

Engineering Contradiction:
Improveinformation display effectivenessVSAvoidcontrol mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The display location selection is made dynamic rather than static. The control apparatus automatically determines the appropriate display location (first display part, second display part, or both) based on real-time assessment of information type, priority level, and occupant context. This dynamic adaptation maximizes information display effectiveness without requiring manual configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where the control apparatus continuously monitors information characteristics and display outcomes, adjusting display location decisions based on this feedback. This closed-loop control ensures that information is presented at the most effective location while automatically adapting to changing conditions.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If personal information is displayed at the wearable terminal, then information accessibility is improved, but privacy protection deteriorates

Engineering Contradiction:
Improveinformation accessibilityVSAvoidprivacy exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Different display locations are assigned different functional qualities appropriate to their characteristics. The wearable terminal (second display part) is designated for personal, private information that requires individual accessibility, while the vehicle main body display (first display part) handles shared information. This local quality differentiation ensures personal information is accessible to the intended occupant while maintaining privacy through physical and functional separation.

Inventive Principle:
Principle #3Local quality

AI summary

A vehicle display nexus control apparatus includes: a first display part provided at a vehicle main body; a wearable terminal that is worn at a head region of an occupant, and that is provided with a second display region disposed in front of an eye of the occupant in a worn state; a display information acquisition unit that acquires information to be displayed at at least one of the first display part or the second display part; and a display location selection unit that determines whether to display the information acquired by the display information acquisition unit at both the first display part and the second display part, at only the first display part, or at only the second display part.
