Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multipath transmission protocol is deployed on server or network device, then data transmission reliability is improved, but deployment cost increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The mobile terminal itself performs multipath transmission protocol processing without requiring external server deployment. The terminal independently manages multiple network interfaces (cellular, Wi-Fi), establishes multiple data channels, and handles protocol operations locally, enabling self-service multipath transmission that eliminates deployment costs while maintaining reliability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a router as an intermediary device that assists the mobile terminal in establishing multiple data channels. The router receives collaboration information from the terminal, provides matching information, and helps coordinate the multipath transmission without requiring server-level deployment, thus reducing costs while improving reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If multipath transmission protocol is deployed on server, then network bandwidth is increased, but communication delay increases

Engineering Contradiction:
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The mobile terminal preliminarily establishes multiple data channels through multiple network interfaces before actual data transmission occurs. By pre-configuring cellular and Wi-Fi channels and having the router ready with matching information, the system eliminates handoff delays and reduces communication latency when transmitting large volumes of data

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments data transmission into parallel channels through different network interfaces (cellular, Wi-Fi). The mobile terminal divides data flow across multiple independent paths, allowing simultaneous transmission through different networks, thereby increasing effective bandwidth while maintaining low latency through parallel processing

Inventive Principle:
Principle #1Segmentation

3Device complexity

If conventional TCP protocol is used, then implementation simplicity is maintained, but network resource utilization decreases

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The mobile terminal utilizes multiple network interfaces (cellular, Wi-Fi, Bluetooth) that are already present in modern devices, making the multipath transmission implementation universally applicable without requiring specialized hardware. The terminal leverages existing multi-functional capabilities to achieve improved network resource utilization while maintaining implementation simplicity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mobile terminal autonomously manages multiple network connections and protocol operations without requiring complex external infrastructure. By self-managing the multipath transmission locally, the terminal achieves better network resource utilization while keeping the implementation relatively simple and avoiding complex server-side deployments

Inventive Principle:
Principle #25Self-service
