Solution Overview

Problem

Existing display switching devices in vehicles switch images on a display device to a camera image even if an input operation is performed, causing interruptions and user frustration.

Innovation Solution

A control device that controls display content on a display device with an input device, switching to specific content only when predetermined conditions are met and preventing such switches during input operations, especially for prolonged or multiple inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display switching device switches to camera image when switching condition is met, then the display device can provide relevant information during input operations, but the display content switches even during user input operations causing interruptions

Engineering Contradiction:
Improvedisplay switching reliabilityVSAvoidinput operation continuity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts the display switching behavior based on the detected state of input operations. When an input operation is detected, the system suspends automatic display switching; when no input operation is detected, normal switching based on predetermined conditions is enabled. This dynamic adaptation resolves the contradiction by making the switching behavior context-dependent rather than fixed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback by continuously monitoring input device status and using this information to control display switching. The control device detects whether an input operation is being performed and feeds this information back to the display switching logic, which then adjusts its behavior accordingly. This feedback mechanism ensures that display switching does not interrupt user input operations.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the display content switches to camera image during input operation, then the switching condition is satisfied, but user frustration increases due to unnecessary switches

Engineering Contradiction:
Improvedisplay switching functionalityVSAvoiduser experience stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system dynamically modifies its switching behavior based on real-time detection of input operations. Instead of rigidly following predetermined switching conditions, the system adapts by suppressing switches when input operations are active, thereby maintaining user experience stability while preserving switching functionality when appropriate.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system takes preliminary anti-action by detecting input operations in advance and preemptively preventing display switches that would interrupt user interactions. This proactive approach stops potential disruptions before they occur, maintaining user experience stability while allowing normal switching to proceed when no input operation is detected.

Inventive Principle:
Principle #9Preliminary anti-action

3Extent of automation

If automatic display switching is enabled, then the display device can automatically show relevant content, but the switching occurs even during prolonged input operations interrupting user workflow

Engineering Contradiction:
Improveautomatic display switchingVSAvoidinput operation smoothness
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The system dynamically controls the extent of automation by enabling automatic switching only when no input operation is detected. When input operations are active, the system manually suppresses automatic switching, thereby preserving input operation smoothness. This dynamic adjustment of automation level resolves the contradiction between automatic switching capability and input operation continuity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from input device monitoring to control automatic display switching. The control device continuously receives feedback about ongoing input operations and adjusts the automatic switching behavior accordingly, suspending it during input operations and enabling it during idle periods. This feedback-based control maintains both automation benefits and operational smoothness.

Inventive Principle:
Principle #23Feedback

AI summary

A control device is configured to content a display content of a display device having an input device. The control device is configured to switch the display content of the display device to a specific display content when a predetermined switching condition stands and not switch the display content of the display device to the specific display content even if the predetermined switching condition stands when it is judged that an input operation has been performed through the input device.
