Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all trajectory data is displayed to provide complete information, then information completeness is improved, but analysis difficulty increases due to information overload

Engineering Contradiction:

Improveinformation completenessVSAvoidanalysis difficulty

Core Design Contradiction:

Loss of informationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent extracts and displays only the necessary trajectory information based on user selections. The controller filters trajectory data to show only relevant staying locations and passing trajectories, removing unnecessary information while preserving essential analysis capabilities.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different display qualities to different parts of the trajectory data. Selected staying locations receive enhanced display attention, while other areas are minimized or hidden, creating a differentiated information presentation that reduces cognitive load.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If detailed trajectory information is displayed to improve analysis accuracy, then measurement precision is improved, but device complexity increases

Engineering Contradiction:

Improveanalysis accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements a dynamic display system that adapts to user interactions. The controller dynamically adjusts which trajectory information is displayed based on user selections of staying locations and designated areas, providing detailed information only when and where needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments trajectory information into distinct components: staying locations, passing trajectories, and other trajectory data. Each segment can be independently controlled and displayed based on user needs, reducing overall system complexity while maintaining analytical precision.

Inventive Principle:

Principle #1Segmentation

3Reliability

If comprehensive trajectory data is processed to ensure data completeness, then information reliability is improved, but processing time increases

Engineering Contradiction:

Improvedata reliabilityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary filtering and organization of trajectory data before display. The controller pre-processes trajectory information to identify and categorize staying locations and relevant trajectories, so that when users interact with the system, the data is already prepared and ready for efficient display.

Inventive Principle:

Principle #10Preliminary action

4Loss of information

If all trajectory information is displayed to provide complete analysis data, then information completeness is improved, but ease of operation deteriorates due to interface complexity

Engineering Contradiction:

Improveinformation completenessVSAvoidinterface ease of use

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent extracts only the essential trajectory information needed for analysis based on user selections. The interface displays selected staying locations and relevant passing trajectories while omitting unnecessary data, reducing interface complexity while maintaining analytical completeness.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A trajectory analysis device that displays relevant information on a trajectory of a moving object, comprising: a display interface to display the relevant information; a storage to store trajectory data indicating a plurality of trajectories and the relevant information; an input interface to receive input by a user operation; and a controller to control the display interface based on the relevant information and the user operation input on the input interface, wherein the controller causes the display interface to display one or more staying locations where trajectories stay, based on the trajectory data, receives an input result by a user operation selecting at least one of the staying locations, receives an input result by a user operation designating a designated location different from the selected staying location, and extracts the relevant information to be displayed on the display interface, based on the selected staying location and the designated location.
