Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for moving platforms, such as UAVs, struggle to dynamically manage bandwidth and adapt to changing network conditions, leading to potential loss or degradation of critical data due to volatile link quality and varying bandwidth requirements among different platform applications.
Innovation Solution
A data communications apparatus and method that includes a communications system and a data management module, which monitors available bandwidth and adjusts transmission parameters of platform applications to ensure efficient use of available bandwidth by comparing bandwidth requirements with current link conditions and generating control signals to adapt data transmission accordingly.

Engineering Contradiction Analysis
1Ease of operation
If data from multiple platform applications is transmitted autonomously over different communication links without centralized management, then each application can independently control its data transmission, but the overall bandwidth usage becomes uncoordinated and may exceed available network resources
Solution Approach 1:
The patent introduces a Quality of Service (QoS) interface as an intermediary layer between platform applications and the communications system. This QoS interface receives bandwidth availability information from the communications system and translates it into control signals for individual applications, enabling coordinated bandwidth management while preserving application independence. The QoS interface acts as a mediator that harmonizes autonomous application transmissions with overall network resource constraints.
2Productivity
If the communication link bandwidth is increased to accommodate all platform applications simultaneously, then all applications can transmit data without bandwidth constraints, but the system complexity and resource consumption increase
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the QoS interface continuously monitors communication link bandwidth availability and adjusts transmission parameters in real-time. Instead of provisioning for maximum simultaneous transmission capacity, the system dynamically adapts to actual bandwidth conditions, allowing high productivity when bandwidth is available while reducing complexity when bandwidth is constrained. This dynamic approach replaces static over-provisioning with adaptive resource utilization.
Solution Approach 2:
The system changes transmission parameters (such as data rate, transmission timing, or compression level) based on monitored bandwidth availability. When bandwidth is sufficient, applications transmit at higher rates; when bandwidth is constrained, the QoS interface signals applications to reduce transmission parameters. This parameter adjustment mechanism enables the system to maintain productivity across varying bandwidth conditions without requiring complex infrastructure for every possible bandwidth scenario.
3Device complexity
If bandwidth allocation is statically predetermined for each platform application, then bandwidth management is simple and predictable, but the system cannot adapt to dynamic changes in network conditions or application priorities
Solution Approach 1:
The patent establishes a feedback loop where the QoS interface continuously receives bandwidth availability information from the communications system and uses this feedback to adjust application transmission behavior in real-time. This feedback mechanism enables the system to adapt to changing network conditions dynamically. The QoS interface monitors bandwidth usage, detects when constraints arise, and signals applications to adjust their transmission parameters accordingly, creating a responsive system that balances simplicity with adaptability.
4Device complexity
If data transmission priority is not differentiated among platform applications, then all data is treated equally simplifying management, but mission-critical data may be lost or delayed when bandwidth is constrained
Solution Approach 1:
The patent applies different quality levels of service to different applications or data types based on their priority requirements. The QoS interface can identify mission-critical applications and allocate bandwidth preferences to them when constraints arise. This local quality differentiation means that while the overall management mechanism remains relatively simple, critical data receives preferential treatment in bandwidth allocation decisions, ensuring reliable delivery without requiring completely complex multi-level management structures.
