Solution Overview

Problem

Existing wireless communication systems for unmanned aerial vehicles (UAVs) fail to efficiently manage bandwidth allocation and real-time data transmission due to power constraints and critical timing requirements, leading to inefficiencies in data transmission and control responsiveness.

Innovation Solution

Implementing a dynamic arbiter system where one node controls bandwidth allocation among other nodes, adjusting transmission cycles and start times based on demand, and allowing for relay functions to maintain network efficiency and power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional wireless systems buffer video data to take advantage of time gaps, then bandwidth utilization improves, but real-time responsiveness deteriorates

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidreal-time responsiveness

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements dynamic transmission control where the arbiter node continuously adjusts transmission parameters based on real-time network conditions and data priority. The system dynamically switches between buffering and immediate transmission modes, adjusting time gaps and transmission timing to balance bandwidth efficiency with real-time responsiveness requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes transmission parameters such as time gaps, buffering depth, and transmission timing based on the priority and nature of data being transmitted. Critical real-time data receives immediate transmission with minimal buffering, while non-critical data can be buffered to optimize bandwidth utilization.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If bandwidth is allocated to transmit high-quality video data, then data transmission quality improves, but power consumption increases

Engineering Contradiction:

Improvedata transmission qualityVSAvoidpower consumption

Core Design Contradiction:

Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by allocating bandwidth selectively based on data priority and transmission requirements. The arbiter node determines the minimum necessary bandwidth for each data stream, transmitting critical real-time data with higher quality when needed while reducing bandwidth allocation for non-critical data, thereby optimizing the balance between transmission quality and power consumption.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system implements feedback mechanisms where the arbiter node monitors network conditions, power availability, and data transmission quality, continuously adjusting bandwidth allocation to maintain optimal performance while conserving power. The feedback loop allows dynamic adaptation to changing conditions.

Inventive Principle:

Principle #23Feedback

3Productivity

If a single arbiter node controls all bandwidth allocation, then transmission control efficiency improves, but system reliability deteriorates

Engineering Contradiction:

Improvetransmission control efficiencyVSAvoidsystem reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces a relay node as an intermediary that can assume the arbiter function when the primary arbiter is unavailable. This mediator approach ensures continuous operation and maintains system reliability by providing backup control capability without compromising the efficiency of the single-arbiter transmission control model under normal conditions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system prepares for arbiter failure by establishing a relay node that can take over the arbiter function. This beforehand cushioning ensures that if the primary arbiter fails, the system can quickly transition to the relay node to maintain transmission control and prevent system collapse.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If bandwidth is allocated for relay functions, then network versatility improves, but transmission priority for critical data deteriorates

Engineering Contradiction:

Improvenetwork versatilityVSAvoidcritical data transmission priority

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments the transmission timeline into different time slots or frames, separating critical data transmission from relay functions. The arbiter node allocates specific time periods for high-priority critical data transmission to ensure they receive adequate bandwidth and attention, while other time periods can be dedicated to relay operations, thereby maintaining both versatility and transmission priority.

Inventive Principle:

Principle #1Segmentation
