Solution Overview

Problem

Existing data transmission systems in airplanes waste bandwidth and storage by transmitting non-essential data, necessitating a more cost-effective method to prioritize and adaptively change data resolution based on emergency situations.

Innovation Solution

A system comprising a memory device, processing devices, and a transmitting device that collects flight data, analyzes it, generates feedback signals to select and adjust the data resolution of critical data for transmission, and transmits only the essential data with optimized resolution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all flight data is transmitted without prioritization, then complete data availability is achieved, but bandwidth and storage resources are wasted

Engineering Contradiction:

Improvedata completenessVSAvoidbandwidth waste

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system segments flight data into different priority levels (first group with first data resolution and second group with second data resolution) based on importance, allowing selective transmission of critical data while reducing overall data volume for transmission

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different data resolution levels are applied to different data groups based on their specific importance - critical data maintains high resolution while non-critical data uses lower resolution, optimizing resource usage while preserving essential information quality

Inventive Principle:

Principle #3Local quality

2Measurement precision

If high data resolution is maintained for all data, then data integrity is preserved, but transmission bandwidth is consumed

Engineering Contradiction:

Improvedata resolutionVSAvoiddata volume

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The system applies different data resolutions locally to different data groups - the first group of flight data uses first data resolution while the second group uses second data resolution, ensuring critical data maintains high precision while reducing overall data volume

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Flight data is segmented into multiple groups with different resolution requirements, allowing the system to transmit only essential data at high resolution while using lower resolution for less critical data, thereby reducing total bandwidth consumption

Inventive Principle:

Principle #1Segmentation

3Loss of information

If non-essential data is transmitted, then comprehensive data coverage is achieved, but storage resources are wasted

Engineering Contradiction:

Improvedata coverageVSAvoidstorage waste

Core Design Contradiction:

Loss of informationVSLoss of substance

Solution Approach 1:

The system extracts and transmits only the essential first group of flight data at high resolution, separating it from non-essential second group data that is transmitted at lower resolution or omitted, thereby achieving comprehensive coverage of critical information while reducing storage waste

Inventive Principle:

Principle #2Taking out (Extraction)
