Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional information sharing systems experience unnecessary communication due to slight changes in shared data, making it inefficient.

Innovation Solution

An information processing method that determines the granularity of data change and transmits only the changed data based on this granularity, optimizing communication by eliminating unnecessary data transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is transmitted whenever any change occurs, then data accuracy is maintained, but communication overhead increases unnecessarily

Engineering Contradiction:

Improvedata accuracyVSAvoidcommunication overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent changes the parameter of data transmission from binary (send/don't send) to granular (send only changed portions). By identifying and transmitting only the specific data elements that have changed rather than entire datasets, the system maintains data accuracy while significantly reducing communication overhead and energy consumption.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent extracts only the changed portions of data from the complete dataset for transmission. By separating changed data elements from unchanged ones and transmitting only the necessary changes, the system avoids sending redundant information while ensuring receiving devices have accurate updated data.

Inventive Principle:

Principle #2Taking out (Extraction)

2Loss of information

If entire datasets are transmitted, then data completeness is ensured, but transmission efficiency decreases

Engineering Contradiction:

Improvedata completenessVSAvoidtransmission efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The patent segments data into individual elements or records that can be independently identified and transmitted. By dividing complete datasets into discrete changeable units and transmitting only those that have changed, the system ensures data completeness for updated elements while improving transmission efficiency by excluding unchanged portions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Inventive Principle:

Principle #2Taking out (Extraction)

3Measurement precision

If high-resolution data is transmitted, then measurement precision is improved, but communication bandwidth consumption increases

Engineering Contradiction:

Improvedata resolutionVSAvoidcommunication bandwidth

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent changes the parameter of data transmission from complete high-resolution datasets to selective high-resolution changes. By transmitting only changed data elements at full resolution rather than complete datasets, the system maintains measurement precision for updated elements while significantly reducing communication bandwidth consumption.

Inventive Principle:
