Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If network protocols are applied without dynamic adaptation, then network coverage and basic connectivity are maintained, but energy consumption increases and network performance deteriorates

Engineering Contradiction:

Improveenergy consumptionVSAvoidadaptation to traffic load

Core Design Contradiction:

Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic adaptation of network protocols by allowing wireless devices to transition between different protocol modes based on real-time traffic load conditions. The network device receives traffic load information from wireless devices and dynamically adjusts protocol application, enabling the system to adapt its behavior to varying network conditions rather than using a static protocol approach.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes operational parameters by adjusting protocol application based on traffic load thresholds. When traffic load exceeds a first threshold, the network device applies first network protocols; when traffic load is below a second threshold, it applies second network protocols. This parameter-based adaptation allows energy consumption and performance characteristics to change according to network conditions.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If standard network protocols are used for all traffic conditions, then protocol compatibility is maintained, but resource allocation becomes suboptimal

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidprotocol selection mechanism

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where wireless devices report traffic load information to the network device, which then adjusts protocol application accordingly. This closed-loop feedback system enables optimal resource allocation by continuously monitoring network conditions and adapting protocol usage, improving productivity while managing device complexity through automated decision-making.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent establishes predetermined threshold values for traffic load that trigger specific protocol applications. By pre-configuring these thresholds and protocol mappings, the system prepares advance decision rules that simplify real-time resource allocation, improving productivity without requiring complex on-the-fly calculations.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If network protocols are applied without considering device capabilities, then protocol implementation is simplified, but network responsiveness to varying device requirements deteriorates

Engineering Contradiction:

Improveresponsiveness to device capabilitiesVSAvoidcapability assessment mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies different network protocols to different wireless devices based on their specific capabilities and traffic load conditions. Instead of using a uniform protocol approach, the system tailors protocol application to local device characteristics, improving adaptability and responsiveness while managing complexity through capability-based categorization.

Inventive Principle:

Principle #3Local quality

4Reliability

If dynamic protocol adjustment is implemented, then energy efficiency and performance are optimized, but network control complexity increases

Engineering Contradiction:

Improvenetwork performanceVSAvoidnetwork control mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables wireless devices to self-assess their traffic load and report this information to the network device, which then autonomously decides which protocol to apply. This self-service approach allows dynamic protocol adjustment and performance optimization while reducing the need for complex centralized control mechanisms, as the system leverages information from the devices themselves.

Inventive Principle:

Principle #25Self-service

AI summary

A central unit (CU) of a base station receives, from a first distributed unit (DU) of the first base station, an information message comprising configuration parameters for transmission of a wake-up signal (WUS), wherein the WUS indicates that a wireless device initiates/requests transmission of a system information block (SIB) via a first cell. The CU sends, to a network node, a first configuration message comprising an indication to transmit the configuration parameters for transmission of the WUS. The CU receives, from the first DU, a notification message comprising at least one of an indication that the first DU keeps, starts, is, or continues transmitting the SIB via the first cell, or an indication that the first DU received the WUS via the first cell. The CU sends, to the network node, a second configuration message comprising an indication to stop transmitting the configuration parameters for transmission of the WUS.
