Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing predictive maintenance systems for mobile devices face limitations in data transmission due to size and processing constraints, and current data prioritization techniques fail to account for the type of data and availability of transmission mediums, leading to inefficient and inflexible data transmission.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data is transmitted using available transmission mediums, then data can be communicated between remote device and back end processing system, but transmission costs increase and bandwidth is limited
Solution Approach 1:
The system performs preliminary actions by assigning priority levels to data packets before transmission and buffering them in priority buffers. This allows the system to prepare data for transmission in advance, selecting the most appropriate transmission medium based on data importance, thereby reducing unnecessary transmission costs while ensuring critical data is transmitted reliably.
Solution Approach 2:
The system changes transmission parameters by selecting different transmission mediums (WLAN, cellular, terrestrial) based on data priority and available bandwidth. High priority data uses higher bandwidth, higher cost mediums while low priority data uses lower bandwidth, lower cost mediums, optimizing the balance between transmission reliability and cost.
2Reliability
If data transmission prioritization is based on service level agreements, then higher priority data receives improved transmission priority, but the system does not account for transmission medium availability and characteristics
Solution Approach 1:
The system dynamically adapts transmission medium selection based on real-time conditions. The priority assignment device considers both data priority levels and current transmission medium availability, bandwidth, and characteristics. This dynamic approach allows the system to flexibly select the most appropriate transmission medium for each data packet, improving both reliability and adaptability.
Solution Approach 2:
The system implements feedback mechanisms where the priority assignment device continuously monitors transmission medium availability and characteristics, and adjusts data packet priority assignment and medium selection accordingly. This feedback loop ensures the system adapts to changing conditions while maintaining optimal transmission priority for critical data.
3Productivity
If scheduling mechanism is adjusted to maximize data submission when communication medium is available, then more data can be transmitted, but higher priority data is not necessarily transmitted first
Solution Approach 1:
The system segments data packets into different priority levels and creates separate priority buffers for each level. This segmentation allows the system to manage multiple data streams simultaneously, ensuring high priority data is transmitted first while still maximizing overall data transmission volume by utilizing available bandwidth for lower priority data in parallel.
Solution Approach 2:
The system maintains continuous useful action by keeping multiple priority buffers active and continuously assigning priority to incoming data packets. When transmission medium is available, the system continuously transmits data from highest priority buffers first, ensuring priority assurance while maximizing throughput by keeping transmission channels continuously utilized.
4Ease of operation
If mobile device uses basic on-board computing system, then processing is simple and binary, but sophisticated computation and cross-referencing capabilities are unavailable
Solution Approach 1:
The system extracts complex computation and cross-referencing functions from the mobile device to the back end processing system. The mobile device retains simple on-board processing for immediate binary determinations, while sophisticated analysis, pattern recognition, and cross-referencing are performed remotely at the back end, preserving information that would be lost with only basic on-board processing.

AI summary
Prioritized transmission of data from a mobile device, where the mobile device includes the ability to transmit data using more than one transmission medium, includes generating data packets from sensor data. The data packet is then assigned a priority level based on the sensor data and various factors relating to the transmission mediums. The priority level may be assigned based on the transmission availability, bandwidth and cost of using the medium. The data packets, based on the assigned priority level, are then stored in a corresponding priority buffer associated with a transmission device using one of the transmission mediums. When available, the transmission device may then readily transmit the data packet from the priority buffer. Therefore, the data is transferred in a prioritized order based, in part, on the transmission medium and factors relating to the medium, as well as the sensor data being transmitted.
