Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single communication protocol is used for all wireless devices, then device compatibility is maintained, but communication efficiency deteriorates due to inability to optimize for specific device and network conditions

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidprotocol adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic protocol selection where the base station selects communication protocols based on real-time device configurations, traffic load, and network conditions. The protocol selection is not fixed but adapts dynamically to current system state, allowing optimization of communication efficiency for different scenarios while maintaining overall system compatibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes protocol parameters selectively based on device type, traffic conditions, and network state. Different protocol configurations are applied to different wireless devices or traffic flows, allowing optimization of communication efficiency for specific conditions while maintaining compatibility across the diverse device ecosystem.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If advanced communication protocols are selectively applied based on device configurations and network conditions, then communication efficiency is improved, but system complexity increases due to multiple protocol management requirements

Engineering Contradiction:
Improveresource utilizationVSAvoidprotocol management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The base station autonomously performs protocol selection and configuration based on pre-defined criteria involving device configurations, traffic load, and network conditions. The system self-manages the complexity of multiple protocols through automated decision-making, eliminating the need for manual protocol management while optimizing resource utilization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors network conditions, device configurations, and traffic load to make informed protocol selection decisions. This feedback mechanism allows the base station to adapt protocol usage based on real-time system state, optimizing resource utilization while managing complexity through data-driven automated decisions.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If communication protocols are dynamically adapted to network conditions, then system adaptability is improved, but processing time increases due to continuous evaluation of selection criteria

Engineering Contradiction:
Improvesystem adaptabilityVSAvoidprotocol selection time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system pre-establishes protocol selection criteria and evaluation frameworks before actual communication occurs. By preparing the decision-making structure in advance, the base station can quickly evaluate current conditions and select appropriate protocols without extensive real-time processing, thus maintaining high system adaptability while minimizing protocol selection time.

Inventive Principle:
Principle #10Preliminary action

AI summary

A wireless device transmits (3210) a first preamble via a cell. The wireless device receives (3220) a downlink grant for a random access response. The wireless device determines (3230) a failure to receive the random access response. The wireless device determines (3240), based on the failure and a time alignment timer of the cell, an uplink signal for transmission via the cell. The uplink signal is one of a second preamble and a negative acknowledgement. The wireless device transmits (3250) the uplink signal.
