Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for connecting mobile devices to vehicle computer systems lack an efficient method to prioritize and manage wireless connections based on user preferences and communication activity, leading to suboptimal pairing and reconnection strategies.
Innovation Solution
A vehicle computer system that automatically creates a priority list using factors such as communication activity, favorite devices, and connection history to determine the order of connecting to mobile devices and manage reconnection attempts, utilizing a wireless transceiver to establish and maintain connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system attempts to connect to all paired mobile devices simultaneously, then the probability of establishing a connection increases, but the system complexity and processing time increase significantly
Solution Approach 1:
The system divides the set of paired mobile devices into ordered priority groups based on connection history and usage patterns. Instead of attempting connections to all devices simultaneously, the system segments them into tiers and attempts connections in sequence from highest to lowest priority, reducing system complexity while maintaining reliable connection establishment.
Solution Approach 2:
The system performs preliminary actions by pre-establishing connection priorities and attempt limits before the actual connection process. This preliminary organization of devices into priority lists with defined connection attempt thresholds allows the system to efficiently manage connection attempts without overwhelming complexity during the connection establishment phase.
2Reliability
If the system attempts to connect to multiple mobile devices with multiple retry attempts, then the connection reliability improves, but the time consumption and energy usage increase
Solution Approach 1:
The system applies different connection strategies to different mobile devices based on their individual characteristics and usage patterns. High-priority devices receive more connection attempts and higher retry thresholds, while lower-priority devices receive fewer attempts. This localized differentiation of connection quality ensures reliable connections for important devices while minimizing time consumption for less critical connections.
Solution Approach 2:
The connection priority and retry thresholds are dynamic rather than static. The system continuously updates connection histories and adjusts priority lists based on recent usage patterns, ensuring that connection resources are dynamically allocated to the most relevant devices. This dynamic approach maintains high connection reliability for currently relevant devices while reducing time spent on outdated or less important connections.
3Adaptability or versatility
If the system maintains a comprehensive list of all paired mobile devices, then the adaptability to user needs improves, but the data management complexity and memory requirements increase
Solution Approach 1:
The system extracts only the essential information needed for connection management from the complete set of paired devices. Instead of maintaining and processing all device details equally, the system extracts key attributes such as connection frequency, recent usage patterns, and priority levels to create simplified priority lists. This extraction approach maintains adaptability to user needs while reducing data management complexity.
4Ease of operation
If the system uses a fixed connection attempt threshold for all devices, then the ease of operation improves, but the connection success rate decreases for frequently used devices
Solution Approach 1:
The system dynamically changes the connection attempt threshold parameter based on device priority and connection history. Instead of using a fixed threshold for all devices, the system adjusts the number of allowed connection attempts and retry thresholds according to each device's priority level. High-priority devices receive higher attempt thresholds to maximize connection success rates, while the system maintains ease of operation through automated parameter adjustment without requiring manual user configuration.
