Solution Overview
Problem
Existing data transmission methods in low-power networks face challenges in maintaining transfer reliability and efficiency due to variable data lengths, leading to increased overhead and interference susceptibility.
Innovation Solution
A data transmission system that distributes variable-length data into a fixed number of sub-data packets, with varying lengths depending on the original data length, and transmits these packets within a specified time interval, maintaining constant temporal distances between packets to minimize interference and overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If variable-length data is transmitted using fixed-number sub-packets with variable lengths, then transfer reliability and efficiency are improved, but device complexity increases due to variable sub-packet length management
Solution Approach 1:
The patent applies dynamics by making the sub-packet lengths variable rather than fixed. The data transmission device dynamically adjusts the length of each sub-packet based on the total data length, dividing the variable-length data into a predetermined number of sub-packets where each sub-packet's length adapts to the overall data requirements. This dynamic approach improves transfer reliability while managing device complexity through systematic length allocation.
Solution Approach 2:
The patent changes the parameter of sub-packet length from fixed to variable. By allowing sub-packet lengths to vary based on the total data length while maintaining a fixed number of sub-packets, the system optimizes transmission efficiency and reliability. The receiver uses the sub-packet length information to correctly reassemble the original variable-length data, resolving the contradiction between reliability improvement and device complexity.
2Productivity
If constant temporal distances are maintained between sub-packets, then interference is reduced and transfer efficiency is improved, but flexibility in handling variable data lengths is limited
Solution Approach 1:
The patent applies dynamics by maintaining constant temporal distances between sub-packets while dynamically adjusting sub-packet lengths. This allows the system to handle variable data lengths flexibly by varying the content within each sub-packet while keeping the transmission timing structure fixed, thereby improving transfer efficiency without sacrificing adaptability to different data lengths.
Solution Approach 2:
The patent changes the parameter approach by fixing the temporal distance parameter between sub-packets while allowing the sub-packet length parameter to vary. This parameter separation enables constant timing intervals that reduce interference and improve efficiency, while the variable sub-packet lengths provide the necessary flexibility to accommodate different data lengths through proper length signaling and allocation.
3Measurement precision
If additional synchronization sequences are added to handle variable data lengths, then data transmission accuracy is improved, but overhead increases and power consumption rises
Solution Approach 1:
The patent extracts the synchronization function from separate synchronization sequences and integrates it into the data structure itself. By embedding synchronization information within the variable-length data framework and using the sub-packet length information for both data reconstruction and synchronization purposes, the system maintains data transmission accuracy while eliminating redundant synchronization sequences, thereby reducing overhead and power consumption in low-power networks.
Solution Approach 2:
The patent applies universality by making the sub-packet length information serve multiple functions: it defines the data boundaries for accurate reconstruction, provides synchronization timing information, and enables efficient resource allocation. This multi-functional approach eliminates the need for separate synchronization sequences, reducing overhead and power consumption while maintaining transmission accuracy.
