Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional PTMP transmission service transmits only homogeneous physical-layer signals in time-division manner, then transmission simplicity is maintained, but adaptability to heterogeneous signals is insufficient

Engineering Contradiction:

Improveadaptability to heterogeneous signalsVSAvoidtransmission configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transmission time is segmented into distinct time-division periods, each dedicated to transmitting specific heterogeneous physical-layer signals. This segmentation allows the system to handle multiple signal types (e.g., 3GPP and non-3GPP signals) separately in time, achieving adaptability while maintaining manageable complexity through structured time allocation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transmission system dynamically adjusts time-division parameters based on the types of signals being transmitted. By making the time-division configuration adaptable to different signal characteristics and requirements, the system achieves versatility without being locked into a fixed complex structure, allowing flexible adaptation to various transmission scenarios.

Inventive Principle:

Principle #15Dynamics

2Productivity

If heterogeneous physical-layer signals are transmitted simultaneously on same frequency resource, then transmission efficiency is improved, but interference between different signal types increases

Engineering Contradiction:

Improvewireless resource usage efficiencyVSAvoidinterference between signals

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system employs periodic time-division transmission, where different heterogeneous signals are transmitted in alternating time periods. This periodic alternation allows multiple signal types to share the same frequency resource efficiently while preventing simultaneous transmission that would cause interference, thus balancing productivity with signal quality.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The time-division transmission structure ensures continuous utilization of wireless resources by alternating between different signal transmissions without idle gaps. This continuous action maximizes productivity while the temporal separation prevents harmful interference, as each signal type is transmitted continuously in its designated time slot without interruption or overlap.

Inventive Principle:

Principle #20Continuity of useful action

3Adaptability or versatility

If time-division period is extended to accommodate more signal types, then transmission versatility is improved, but transmission delay increases

Engineering Contradiction:

Improvenumber of signal types supportedVSAvoidtransmission delay

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The transmission time is divided into smaller discrete time-division periods, each dedicated to specific signal types. This fine-grained segmentation allows the system to support multiple signal types with minimal delay by allocating brief, dedicated slots for each, rather than requiring a single extended period, thus achieving versatility without significant time loss.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system allocates time-division periods based on the actual transmission needs, using only the necessary time for each signal type rather than over-allocating. This partial action approach ensures that the time-division structure adapts to real requirements, supporting multiple signal types while minimizing unnecessary delay from excessive time allocation.

Inventive Principle:

Principle #16Partial or excessive action
