Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If satellite networks provide coverage to remote locations and increase coverage region, then coverage area is improved, but network congestion increases and resource constraints worsen
Solution Approach 1:
The patent segments application traffic into different priority levels (first priority applications and second priority applications). The wireless device classifies applications based on their resource requirements and network conditions, allowing selective transmission. This segmentation enables the system to manage limited satellite network resources by prioritizing critical applications while deprioritizing less critical ones, thus resolving the contradiction between wide coverage and limited network capacity.
Solution Approach 2:
The patent applies partial action by selectively enabling or disabling application traffic based on network conditions and priority levels. Instead of allowing all applications to transmit simultaneously (excessive action), the system permits only essential applications to use satellite network resources, while blocking non-essential applications. This partial action approach optimizes resource utilization across the extensive coverage area provided by satellite networks.
2Ease of operation
If satellite networks provide coverage to remote locations, then accessibility is improved, but bandwidth decreases and latency increases
Solution Approach 1:
The patent implements dynamic application prioritization where the wireless device continuously monitors network conditions and adjusts application traffic management in real-time. The device dynamically determines which applications receive priority treatment based on current network status, ensuring that critical applications maintain optimal performance even as bandwidth and latency vary across the satellite coverage area. This dynamic approach preserves accessibility while adapting to changing network performance characteristics.
Solution Approach 2:
The patent applies local quality by treating different applications differently based on their specific requirements and current network conditions. Instead of uniform treatment of all traffic, the system assigns different quality levels (priority levels) to different applications. Critical applications receive higher quality service with guaranteed bandwidth and lower latency, while non-critical applications accept reduced quality. This differentiated approach maintains accessibility for essential services while managing the inherent bandwidth and latency constraints of satellite networks.
3Adaptability or versatility
If wireless devices access all applications on satellite network, then user functionality is improved, but resource constraints are worsened
Solution Approach 1:
The patent extracts non-essential application traffic from the satellite network connection. The wireless device identifies applications that are not critical for basic communication and functionality, and extracts (blocks) their traffic from using satellite network resources. This extraction allows the remaining essential applications to access the network without resource constraints, while non-essential applications are redirected or blocked. This approach preserves core user functionality while eliminating the resource consumption that would otherwise overwhelm the satellite network.
Solution Approach 2:
The patent introduces an intermediary layer in the form of a wireless device that mediates between applications and the satellite network. This intermediary (the wireless device's application prioritization mechanism) acts as a gatekeeper, determining which applications can access network resources and which cannot. The intermediary evaluates application requirements and network conditions, making selective allowance. This mediation enables the system to maintain versatile user functionality for essential applications while preventing resource-intensive applications from overwhelming the constrained satellite network infrastructure.
