Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing predictive maintenance systems for mobile devices, such as vehicles, face limitations in data transmission due to size and processing constraints, and current techniques fail to efficiently select transmission mediums based on sensor data priority and network availability, leading to suboptimal data exchange and increased costs.
Innovation Solution
A system that includes a sensor data packet generation device, network availability database, and navigation device, which assigns priority levels to sensor data packets based on navigational information and network data to determine the most suitable transmission medium and method for data transmission, optimizing the use of available networks and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data is transmitted using available transmission mediums based on network availability, then data can be exchanged between mobile device and back end processing system, but transmission costs increase and data priority is not considered
Solution Approach 1:
The system changes the parameter of transmission medium selection by introducing priority-based routing. Instead of uniformly using available networks, the system adjusts which transmission medium is used based on data packet priority levels, thereby optimizing the balance between transmission reliability and cost.
Solution Approach 2:
Different transmission mediums are assigned to different priority levels of data packets. High priority packets use reliable but expensive mediums (e.g., cellular), while low priority packets use cost-effective mediums (e.g., WLAN), creating localized optimization for each data type.
2Ease of operation
If basic computation is performed on-board the mobile device, then processing can be done with limited resources, but only binary determinations can be made without sophisticated analysis
Solution Approach 1:
The processing function is segmented between on-board and back-end systems. The on-board device performs initial data collection and basic filtering, while sophisticated analysis is performed remotely at the back end, dividing the computational workload according to capability constraints.
Solution Approach 2:
A communication interface acts as an intermediary between the on-board processing system and the back-end processing system, enabling the mobile device to transmit sensor data for remote analysis while maintaining basic local functionality.
3Loss of information
If sophisticated computation is performed at the back end processing system, then greater analysis capability is available, but the mobile device must transmit data over limited bandwidth mediums
Solution Approach 1:
Non-critical data and processing functions are extracted from the mobile device and relocated to the back-end system. Only essential sensor data and control commands are transmitted over the limited bandwidth communication channel, reducing the data transmission burden.
4Length of stationary object
If data is transmitted using terrestrial connection for global range, then transmission coverage is maximized, but costs increase and bandwidth is limited
Solution Approach 1:
The system dynamically selects transmission mediums based on real-time conditions including data priority, network availability, and cost considerations. The transmission medium is not fixed but adapts to changing conditions, allowing the system to use terrestrial connections only when necessary for high-priority data requiring global coverage.
