Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If handover is based only on signal strength comparison, then handover process is simple, but packet loss occurs during handover and data transfer is disrupted

Engineering Contradiction:

Improvehandover process complexityVSAvoiddata transfer continuity

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system performs preliminary packet loss detection and characterization on the source access node before initiating handover. By identifying packet loss characteristics in advance and using them as a trigger condition, the system ensures reliable data transfer continuity without complicating the handover process structure.

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If handover is delayed until signal strength drops significantly, then network stability is maintained, but packet loss increases and data transfer efficiency decreases

Engineering Contradiction:

Improvenetwork stabilityVSAvoiddata transfer efficiency

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The system implements feedback by continuously monitoring packet loss characteristics and using this information to trigger handover decisions. This feedback mechanism allows the system to proactively initiate handover before signal strength degrades significantly, maintaining both network stability and data transfer efficiency.

Inventive Principle:

Principle #23Feedback

3Reliability

If packet loss threshold is set low for early handover, then data transfer continuity is improved, but unnecessary handovers increase and network stability decreases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The system changes the handover triggering parameter from signal strength alone to packet loss characteristics. By monitoring packet loss rate and comparing it against a threshold, the system achieves early handover for data continuity while avoiding unnecessary handovers through intelligent parameter selection.

Inventive Principle:

Principle #35Parameter changes

4Reliability

If handover is initiated proactively based on packet loss, then data transfer continuity is improved, but handover frequency increases

Engineering Contradiction:

Solution Approach 1:

The system introduces packet loss characteristic analysis as an intermediary condition between signal strength monitoring and handover execution. This intermediary layer filters out unnecessary handover triggers, ensuring handovers occur only when truly needed for maintaining data transfer continuity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A data communication system identifies a target wireless access node for a wireless communication device. The data communication system determines a packet loss characteristic for a wireless transfer of packet data between the wireless communication device and a source wireless access node. The data communication system requests a handover of the wireless communication device from the source wireless access node to the target wireless access node in response to the packet loss characteristic.
