Solution Overview

Problem

Existing in-vehicle display systems lack efficient methods to coordinate and prioritize operations between multiple display units, particularly in vehicles, where safety and user experience are compromised due to limited control over display content and operations during travel.

Innovation Solution

An in-vehicle display system with a controller that selects which display unit to authorize operations based on content type, display unit attributes, vehicle information, and operation details, allowing for coordinated operations between multiple display units to enhance system functionality and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single display unit is given priority to operate content, then display content integrity is protected, but system functionality and flexibility are reduced

Engineering Contradiction:

Improvedisplay content integrityVSAvoidsystem functionality

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic authority assignment where the controller selectively assigns operation authority to different display units based on real-time conditions. The priority display unit concept is enhanced by allowing the non-priority display unit to operate content under specific conditions (when the priority unit is unavailable or in certain states), creating a flexible, dynamic control system that adapts to various operational scenarios rather than maintaining rigid static priority rules

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent applies different operation rules to different display units based on their specific roles and states. The priority display unit maintains strict protection for content integrity, while the non-priority display unit is granted conditional operation permissions. This localized quality differentiation allows each display unit to operate under appropriate constraints, resolving the contradiction between content protection and system flexibility

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple display units can operate content simultaneously, then system functionality is improved, but display content integrity and safety are compromised

Engineering Contradiction:

Improvesystem functionalityVSAvoiddisplay content integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The controller serves as an intermediary that mediates between multiple display units seeking to operate content. It receives operation requests from both priority and non-priority display units, evaluates conditions, and selectively grants authority. This intermediary mechanism enables controlled simultaneous or sequential operation while maintaining content integrity through centralized arbitration

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically adjusts operation permissions based on real-time conditions. The non-priority display unit can gain operation authority when the priority unit is unavailable, creating a dynamic balance between content protection and system functionality. This dynamic authority transfer allows flexible multi-unit operation without compromising integrity

Inventive Principle:

Principle #15Dynamics

3Reliability

If complex control rules are implemented for multiple display units, then display content integrity is protected, but ease of operation is reduced

Engineering Contradiction:

Improvedisplay content integrityVSAvoiduser operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements automatic condition evaluation and authority assignment without requiring complex user intervention. The controller automatically monitors the state of display units, evaluates operation requests against predefined conditions, and grants authority seamlessly. This self-service mechanism handles complex control logic internally while presenting a simple interface to users

Inventive Principle:

Principle #25Self-service

4Ease of operation

If simple control rules are used for multiple display units, then ease of operation is improved, but display content integrity and safety are compromised

Engineering Contradiction:

Improveuser operation simplicityVSAvoiddisplay content integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The controller as intermediary automatically enforces integrity protection rules without requiring complex user input. It transparently evaluates operation requests, checks conditions, and makes authorization decisions based on predefined safety criteria. This intermediary layer maintains simple user interaction while ensuring content integrity through automated control

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An in-vehicle display system is provided with first display unit, second display unit, vehicle information acquisition unit, and CPU. When a display operation for outputting at least a portion of first content to second display unit with the first content being output to first display unit is performed, CPU selects either of first display unit and second display unit with which to associate an authority to operate the output of at least one of first display unit and second display unit according to at least one signal from among a plurality of signals indicating a type of the first content, an attribute of first display unit, an attribute of second display unit, vehicle information, and a detail of the display operation.
