Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple link connections are established and maintained in wireless communication, then connection reliability and data throughput are improved, but power consumption increases significantly

Engineering Contradiction:

Improveconnection reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic beacon reception patterns where the wireless device alternates between active listening intervals and sleep intervals across multiple links. Instead of continuously monitoring all links, the device periodically wakes up to receive beacons at predetermined intervals, maintaining connection reliability while significantly reducing power consumption during idle periods.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent dynamically adjusts the beacon reception pattern based on link activity and priority. The system can switch between different reception patterns (e.g., dense pattern for high activity, sparse pattern for low activity) and dynamically select which link to activate for beacon reception based on current communication needs, optimizing the balance between reliability and power consumption in real-time.

Inventive Principle:

Principle #15Dynamics

2Use of energy by moving object

If beacon reception intervals are increased to reduce power consumption, then power efficiency improves, but connection monitoring and roam performance degrade

Engineering Contradiction:

Improvepower efficiencyVSAvoidconnection monitoring

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

The patent applies partial action by selectively monitoring only the most relevant links during beacon reception periods rather than continuously monitoring all links. The system receives beacons on a subset of links based on priority and activity level, maintaining sufficient connection monitoring capability while reducing power consumption compared to full continuous monitoring.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system uses feedback from beacon reception results to dynamically adjust future beacon reception patterns. When beacons indicate active communication or potential roam conditions, the system increases monitoring frequency on relevant links. When links are idle, monitoring is reduced, creating a feedback loop that maintains connection reliability while optimizing power efficiency based on actual network conditions.

Inventive Principle:

Principle #23Feedback

AI summary

Systems and methods use a protocol for multilink operations. The systems and methods can use a circuit configured to provide frames across a connection comprised of one or more links to a second device. The circuit is configured to use a beacon reception pattern where first intervals on a first link are alternately disposed with second intervals on a second link or to select a beacon reception pattern for a first link, a second link, and a third link in response a low battery condition, a delivery traffic indication map setting, or a roam decision.
