Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing data storage and recharging of mobile machines at worksites, such as haul trucks and paving machines, face challenges due to limited onboard memory capacity and the reliance on high-speed network connections, which can lead to data loss and inefficient work stoppages.
Innovation Solution
A system that establishes a data connection between a mobile machine and a charging unit, allowing the transfer of electronic files from the machine's memory to the charging unit's memory, with the charging unit indicating storage completion and optionally deleting files from the machine's memory, and facilitating transfer to a remote system controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wireless transmission of vehicle data is used between the machine and external server, then data can be transmitted remotely, but the system requires high-speed and robust network connection which may not be available in work environments
Solution Approach 1:
The patent introduces a charging unit as an intermediary device that receives data from the machine's onboard memory during charging sessions. This mediator enables data transfer without requiring direct high-speed network connection between the machine and external server, solving the problem of network unavailability in work environments.
Solution Approach 2:
The system performs preliminary data transfer to the charging unit's memory during charging sessions before the machine needs to operate. This advance action ensures data is safely stored externally without requiring network connection during critical work periods, addressing the network availability issue.
2Loss of information
If data is stored in onboard memory until network connection is established, then data can be transmitted when connection is available, but the onboard memory capacity is limited and data may be lost
Solution Approach 1:
The patent divides the storage system into two segments: the machine's limited onboard memory and the charging unit's external memory. This segmentation allows the machine to store only essential operational data locally while offloading bulk data storage to the charging unit, effectively expanding total storage capacity without increasing onboard memory.
Solution Approach 2:
The charging unit acts as an external memory intermediary, providing expanded storage capacity. Data is transferred from the machine's limited onboard memory to the charging unit's larger memory capacity during charging sessions, preventing data loss due to onboard memory limitations.
3Use of energy by moving object
If the machine returns to charging zone for recharging, then the energy storage device can be recharged, but work stoppages occur and efficiency is reduced
Solution Approach 1:
The patent merges two previously separate functions into a single charging session: energy recharging and data transfer. By combining these operations, the machine achieves dual purposes during necessary charging stops, maximizing the utility of charging time and reducing overall work stoppages.
Solution Approach 2:
The system ensures continuous useful action by performing data transfer during charging sessions rather than requiring separate dedicated data transfer time. This continuity principle ensures that whenever the machine is charging (a necessary stop), productive data management activities occur simultaneously, minimizing net work stoppage time.

AI summary
A method includes establishing a data connection between a first controller, and a second controller of a mobile machine. The method also includes causing, by the first controller, a charging unit to direct electrical current to an energy storage device of the mobile machine. The method further includes receiving, by the first controller a plurality of electronic files stored in a memory of the mobile machine, and storing the files in a memory of the charging unit. The method also includes providing to the second controller, by the first controller, an indication that each file of the plurality of electronic files has been stored in the memory of the charging unit. In such methods, second controller is configured to delete each file of the plurality of electronic files from the memory of the mobile machine based on the indication.
