Multiunit Charging Device Preemptive Data Upload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for uploading data from body-worn cameras and mobile devices used by first responders are inefficient, either causing delays due to sequential uploads or inefficient bandwidth usage when done simultaneously.
Innovation Solution
A multi-unit charging device with a controller that preemptively manages data uploads by prioritizing devices with smaller data sets, pausing uploads on devices with larger data sets when a device with a smaller data set is detected, allowing for concurrent uploading based on data size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data upload is performed sequentially in order of receipt, then bandwidth usage is optimized, but wait time for first responders increases
Solution Approach 1:
The system performs preliminary assessment of data size for each mobile device upon insertion into the charging station. Based on this preliminary information, the controller pre-determines the upload sequence before actual data transfer begins, allowing optimization of both bandwidth usage and wait time by prioritizing devices with smaller data sets.
Solution Approach 2:
The upload sequence is made dynamic rather than static. The controller continuously monitors which devices are inserted and adjusts the upload sequence in real-time based on current device data sizes and insertion order, allowing the system to adapt to changing conditions and optimize performance.
2Loss of time
If data upload is performed simultaneously from all mobile devices, then wait time is reduced, but bandwidth usage becomes inefficient
Solution Approach 1:
The system segments the simultaneous upload process into multiple sequential stages based on device data sizes. Instead of all devices uploading at once, the controller divides them into groups and manages uploads in an optimized sequence, preventing bandwidth overload while minimizing total wait time through parallel processing of multiple devices.
3Productivity
If mobile devices with large data sets are prioritized for upload, then complete data transfer is achieved, but devices with smaller data sets experience longer wait times
Solution Approach 1:
The system inverts the conventional approach by prioritizing devices with smaller data sets for upload first, rather than prioritizing those with larger data sets. This inversion ensures that devices can be returned to first responders more quickly, improving overall system throughput and reducing wait times, while still ensuring all devices eventually complete their uploads.

AI summary
A multiunit charging device and method for preemptive data upload is provided. A multiunit charging device controls a first mobile device, received at a plurality of charging stations of the multiunit charging device, to upload first data via a communication unit. After upload of the first data has begun, the multiunit charging device detects that a second mobile device is received at the plurality of charging stations. When an amount of second data for upload at the second mobile device is smaller than a remaining amount of the first data for upload at the first mobile device, the multiunit charging device: preempts uploading of the first data at the first mobile device; and controls the second mobile device to upload the second data via the communication unit.
