Parking Assistance Device Speed-Based Thumbnail Filtering

Solution Overview

Problem

Current parking assistance devices confuse drivers by displaying unnecessary thumbnail options for parking and exit maneuvers, leading to incorrect selections and wasted time, especially in situations where the vehicle's speed history is not accurately considered.

Innovation Solution

A device that determines the current parking phase by comparing current and previously recorded vehicle speeds, displaying representative images only for the appropriate phase, and using image analysis to detect the type of parking zone, offering tailored options to the driver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all parking phase thumbnails are displayed regardless of vehicle speed history, then the driver is provided with all possible parking options, but the selection process becomes more complex and time-consuming

Engineering Contradiction:

Improvecompleteness of parking optionsVSAvoidselection process complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes irrelevant parking phase thumbnails from the display based on vehicle speed history analysis. By comparing current speed with previously recorded speed, the system identifies whether the vehicle is entering or exiting a parking zone and displays only the relevant thumbnails, thereby simplifying the selection process while maintaining adaptability to the actual parking situation

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary analysis of vehicle speed history before displaying thumbnails. By pre-determining the parking phase (entry or exit) based on speed comparisons, the system prepares and displays only the appropriate thumbnails in advance, preventing driver confusion and reducing selection time

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If all parking phase thumbnails are displayed regardless of vehicle speed history, then all parking options are available to the driver, but the time required for selection increases

Engineering Contradiction:

Improveavailability of parking optionsVSAvoidselection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent extracts and removes irrelevant parking phase thumbnails from the display based on vehicle speed history analysis. By comparing current speed with previously recorded speed, the system identifies whether the vehicle is entering or exiting a parking zone and displays only the relevant thumbnails, thereby simplifying the selection process while maintaining adaptability to the actual parking situation

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary analysis of vehicle speed history before displaying thumbnails. By pre-determining the parking phase (entry or exit) based on speed comparisons, the system prepares and displays only the appropriate thumbnails in advance, preventing driver confusion and reducing selection time

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If thumbnails for both entry and exit are displayed indiscriminately, then all possible maneuvers are shown, but driver confusion increases leading to incorrect selections

Engineering Contradiction:

Improvecompleteness of maneuver optionsVSAvoidselection accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts and removes irrelevant parking phase thumbnails from the display based on vehicle speed history analysis. By comparing current speed with previously recorded speed, the system identifies whether the vehicle is entering or exiting a parking zone and displays only the relevant thumbnails, thereby simplifying the selection process while maintaining adaptability to the actual parking situation

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses vehicle speed history as feedback to dynamically adjust the thumbnail display. By continuously monitoring and comparing speed data, the system provides feedback about the current parking phase and adjusts the displayed options accordingly, ensuring that only relevant maneuvers are shown and reducing driver confusion

Inventive Principle:

Principle #23Feedback
