Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle display systems suffer from redundant screen displays when specific functions like adaptive cruise control (ACC) are turned off, leading to unnecessary visual clutter and complicating user selection.

Innovation Solution

A vehicle display control device that dynamically switches between multiple screen displays, reducing the number of displays when the ACC function is off and inserting the ACC screen display into the sequence when it is on, allowing for seamless integration and reduced user effort in navigating screen options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the specific screen display is always displayed regardless of function state, then the display structure is simple, but redundant screen displays occur when the function is off

Engineering Contradiction:

Improvedisplay structureVSAvoidnumber of screen displays

Core Design Contradiction:

Device complexityVSQuantity of substance

Solution Approach 1:

The patent applies dynamics by making the number of screen displays variable rather than fixed. The display control device dynamically adjusts the number of screen displays based on the on/off state of specific functions. When a function is activated, its corresponding screen display is added to the sequence; when deactivated, it is removed. This dynamic adjustment eliminates redundant displays while maintaining system simplicity.

Inventive Principle:

Principle #15Dynamics

2Quantity of substance

If the number of screen displays is reduced when function is off, then visual clutter is minimized, but the function information becomes inaccessible

Engineering Contradiction:

Improvenumber of screen displaysVSAvoidfunction information

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent applies preliminary action by pre-configuring the display control device to automatically add or remove screen displays based on function activation. The system is prepared in advance with a sequence of screen displays corresponding to different functions, and the control logic is pre-programmed to adjust the displayed sequence according to the current functional state, ensuring information is available when needed without manual intervention.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple screen displays are always available for switching, then user selection flexibility is high, but navigation complexity increases

Engineering Contradiction:

Improveuser selection flexibilityVSAvoidnavigation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by making the display sequence context-dependent. Instead of providing all possible screen displays uniformly, the system adjusts the local display configuration based on the current functional state. Each function's screen display is included in the switchable sequence only when that function is active, providing locally optimized flexibility without global navigation complexity.

Inventive Principle:

Principle #3Local quality
