Solution Overview

Problem

Existing wireless multipath transmission methods face challenges in efficiently distributing data packets across different links due to unpredictable link statuses and dynamic bandwidth allocation, leading to reduced throughput and increased delay, with potential data transmission failures when links fail.

Innovation Solution

Encoding original data packets into a greater number of encoded packets, which are then transmitted through various links, allowing the receiving end to decode and reconstruct the original packets, while considering link status and bandwidth for optimal distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data packets are distributed across multiple transmission links, then data transmission reliability is improved, but transmission delay increases due to unpredictable link statuses and dynamic bandwidth allocation

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidtransmission delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by performing encoding of original data packets into encoded data packets before transmission. This preprocessing step ensures that even if some transmission links fail or experience delays, the receiving end can reconstruct the original data from the encoded packets received through available links, thereby reducing the impact of transmission delays while maintaining reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the parameter of data packet structure by encoding original data packets into multiple encoded data packets with different characteristics. This transformation allows the system to adapt to varying link conditions by distributing encoded packets across multiple links with different bandwidths and reliability levels, optimizing the trade-off between transmission reliability and delay

Inventive Principle:
Principle #35Parameter changes

2Reliability

If encoded data packets are transmitted through multiple links, then data integrity is improved, but system complexity increases due to encoding and decoding operations

Engineering Contradiction:
Improvedata integrityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces encoding and decoding as intermediary processes between the transmitting and receiving ends. These intermediaries transform original data packets into encoded form for transmission and reconstruct them at the receiving end, ensuring data integrity while managing complexity through standardized encoding/decoding operations that can be implemented using established error correction codes

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments original data packets into multiple encoded data packets for distribution across different transmission links. This segmentation allows the system to achieve data integrity through redundancy while managing complexity by dividing the transmission task into independent packet segments that can be processed and transmitted separately

Inventive Principle:
Principle #1Segmentation

3Productivity

If link resources are efficiently utilized through encoding, then throughput is improved, but transmission delay increases due to encoding processing time

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs encoding as a preliminary action before data transmission, allowing the encoding process to be completed in advance and the encoded packets to be ready for immediate transmission. This reduces the impact of encoding processing time on overall transmission delay while maximizing throughput by having encoded packets ready for efficient distribution across multiple links

Inventive Principle:
Principle #10Preliminary action
