Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transfer methods face issues with uncontrolled data loss due to temporary bandwidth fluctuations and interference, making it impossible to determine which data is lost and impacting meaningful analysis.
Innovation Solution
A method is introduced where a selection rule is chosen from a set of predefined rules based on the data analysis and the status of the data connection between the transmitter and receiver, ensuring that only necessary data for analysis is transmitted, optimizing the available data connection.

Engineering Contradiction Analysis
1Quantity of substance
If data is compressed to transfer large volumes, then bandwidth efficiency is improved, but data loss becomes uncontrolled and undetectable
Solution Approach 1:
The system performs preliminary actions by adding redundancy information and checksums to the data before compression and transmission. This allows the receiver to detect and potentially correct data loss without requiring retransmission, resolving the contradiction between compressing large data volumes and maintaining transmission reliability.
Solution Approach 2:
The patent applies beforehand cushioning by incorporating error correction codes and redundancy data into the compressed data stream. This cushioning layer protects against data loss during transmission, enabling reliable recovery even when bandwidth fluctuations cause packet loss, thus maintaining reliability while allowing aggressive compression.
2Loss of information
If all analysis-relevant data is transmitted, then analysis completeness is improved, but bandwidth consumption increases and data loss risk increases
Solution Approach 1:
The system extracts and transmits only the most critical analysis-relevant data features while leaving less important data to be reconstructed or inferred at the receiver side. This selective extraction reduces bandwidth consumption while maintaining sufficient analysis completeness by focusing transmission resources on essential information.
Solution Approach 2:
The patent dynamically changes transmission parameters such as compression ratio, data sampling rate, and redundancy level based on available bandwidth conditions. When bandwidth is limited, it adjusts parameters to prioritize critical data transmission, maintaining analysis completeness under varying bandwidth constraints without consistently consuming high bandwidth.
3Productivity
If compression is applied to ensure reliable transfer, then data transmission efficiency is improved, but the ability to detect data loss is reduced
Solution Approach 1:
The patent introduces checksums and redundancy information as intermediary elements between the original data and the compressed transmission stream. These intermediaries serve as detectors that enable verification of data integrity after decompression, allowing the system to maintain high compression ratios while recovering data loss detection capability through the intermediary verification mechanisms.

AI summary
The invention relates to a method for transmitting analysis-relevant data from a transmitter (2), in which the analysis-relevant data is present, to a receiver (4), in which data analyses can be performed. In order to improve the method for transmitting analysis-relevant data from the transmitter (2) to the receiver (4), according to the invention one selection rule (30) to be applied to the analysis-relevant data is selected for a data transmission from a plurality of predefinable selection rules (26) for the selection of data to be transmitted from the analysis-relevant data, wherein the selection of the selection rule (30) to be applied for this data transmission is dependent on a data analysis applied to the data to be transmitted and on a state of the data link (6) between the transmitter (2) and the receiver (4). Moreover, the data to be transmitted is selected from the analysis-relevant data according to the selection rule (30) selected and the data to be transmitted is transmitted from the transmitter (2) to the receiver (4).
