Solution Overview
Problem
Mobile devices within vehicles face mobility constraints when trying to connect to wireless networks, especially when the vehicle is in motion, as they typically require proximity to wireless access points, limiting their effective range and usability.
Innovation Solution
A vehicular wireless network mobile router is designed with both a local area network interface and a wide area network interface, equipped with processors to manage communication links, a communication agent to upload data, and features for prioritizing and managing data transmission, ensuring connectivity whether the vehicle is stationary or moving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices use wireless access points for network connectivity, then network access is provided, but mobility is constrained due to proximity requirements
Solution Approach 1:
The patent introduces a mobile router as an intermediary device between the mobile device and the wireless access point. The mobile router acts as a mediator that extends the network coverage by creating a wireless mesh network, allowing mobile devices to maintain connectivity without being physically close to the access point. This resolves the contradiction by providing both reliable network access and enhanced mobility through the intermediary routing function.
Solution Approach 2:
The patent implements mesh networking that adds a dimensional layer to traditional point-to-point wireless connectivity. Instead of direct connection to access points, devices connect through multiple intermediate nodes in a three-dimensional mesh structure. This dimensional expansion allows devices to maintain network access while moving freely through the vehicle interior, resolving the mobility-constraint contradiction.
2Adaptability or versatility
If mobile routers are used to expand mobility in vehicles, then connectivity is improved, but data upload reliability deteriorates due to intermittent communication links
Solution Approach 1:
The patent implements preliminary actions by buffering data locally in the mobile router's memory before upload opportunities arise. The system proactively collects and stores data during periods of connectivity, preparing it for subsequent transmission. This preliminary data accumulation ensures that even when communication links are intermittent, data can be reliably uploaded when connectivity is available, resolving the reliability contradiction.
Solution Approach 2:
The patent implements feedback mechanisms where the mobile router continuously monitors communication link status and adjusts data upload operations accordingly. When connectivity is detected, the system feedback-driven resumption of data transmission ensures reliable data transfer. This feedback loop allows the system to adapt to intermittent connectivity conditions and maintain reliable data upload performance.
3Productivity
If continuous data transmission is attempted during mobile movement, then data upload productivity is improved, but communication link stability deteriorates
Solution Approach 1:
The patent implements periodic data transmission actions rather than continuous transmission. The mobile router transmits data in scheduled intervals or batches, pausing during periods of poor connectivity and resuming when conditions improve. This periodic action pattern maintains productivity by utilizing available bandwidth efficiently while preserving communication link stability by avoiding forced continuous transmission during unstable periods.
Solution Approach 2:
The patent implements dynamic adjustment of data transmission parameters based on real-time communication link conditions. The system dynamically modulates upload rate, packet size, and transmission frequency according to current network quality. This dynamic adaptation allows the system to maximize productivity when connectivity is stable while maintaining link reliability when conditions deteriorate, resolving the contradiction between productivity and stability.
