Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is transmitted through a single wireless link in conventional systems, then device complexity is low, but reliability and real-time property are insufficient for MTC applications

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the transmission path by dividing data into multiple packets and transmitting them through different wireless links (first link and second link) simultaneously. This segmentation allows the system to achieve higher reliability through diversity transmission while managing complexity through structured packet handling and selection at the receiver side.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a spatial dimension to transmission by utilizing multiple wireless links instead of a single link. This dimensional expansion enables simultaneous transmission paths, improving reliability through spatial diversity while the receiver manages the increased complexity through selective packet processing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Speed

If multiple wireless links are used for transmission, then real-time property and reliability improve, but device complexity increases

Engineering Contradiction:
Improvetransmission speedVSAvoidtransmission system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

Data is segmented into multiple packets that can be transmitted in parallel through different wireless links, enabling faster overall transmission. The receiver uses segmentation-based reassembly and selection mechanisms to manage the complexity of handling multiple simultaneous transmission streams.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent maintains continuous transmission by sending different data packets simultaneously through multiple links rather than sequentially. This continuous parallel action improves transmission speed while the receiver's selective processing keeps system complexity manageable.

Inventive Principle:
Principle #20Continuity of useful action

3Loss of time

If conventional single-link transmission is used, then system complexity is low, but real-time property cannot meet MTC requirements

Engineering Contradiction:
Improvetime delayVSAvoidtransmission system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

By segmenting data into multiple packets transmitted simultaneously through different links, the system reduces overall transmission time through parallel processing. The receiver manages the complexity of multi-link coordination through structured packet selection and reassembly procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-establishing multiple wireless links and preparing transmission paths before actual data transmission. This preliminary setup enables faster real-time transmission while the structured link management keeps system complexity controllable.

Inventive Principle:
Principle #10Preliminary action
