Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all observation data is transmitted to ground station, then complete observation information is available, but data transmission time is prolonged

Engineering Contradiction:

Improveobservation data completenessVSAvoiddata transmission time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent extracts and processes observation data on the satellite itself using an image generation unit and detection unit. The detection unit identifies detection targets from observation data before transmission, extracting only necessary information for ground station processing, thereby reducing transmission data volume and time while maintaining detection effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If observation data is processed on ground station, then processing flexibility is maintained, but detection time is delayed

Engineering Contradiction:

Improveprocessing flexibilityVSAvoiddetection time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent performs preliminary processing actions on the satellite by generating images from observation data and detecting targets before data transmission. The image generation unit creates processed images and the detection unit identifies targets in advance, so ground station receives pre-processed data ready for final analysis, reducing overall detection time while maintaining operational flexibility.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If vessel detection is performed after data reception, then accurate detection is achieved, but detection timing is delayed

Engineering Contradiction:

Improvedetection accuracyVSAvoiddetection timing

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary detection actions on the satellite using the detection unit that identifies detection targets from generated images before data transmission. This preliminary detection allows ground station to receive pre-identified target information, enabling faster final confirmation and notification while maintaining detection accuracy through multi-stage verification.

Inventive Principle:

Principle #10Preliminary action
