Frontend Component Profile Update via Inductive Power Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices often struggle to receive over-the-air updates or downloads of profile information when outside a geographic coverage area or in low power modes, as they require significant battery power and specific network connectivity.
Innovation Solution
A mechanism where a device can draw power from a second wireless device to enable the download and transfer of profile information using a frontend component, allowing for D2D communication and power transfer via electromagnetic induction, thus bypassing the need for traditional OTA updates and reducing battery drain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional OTA updates are used to download profile information, then the device can receive updates remotely, but the device requires significant battery power and network connectivity which may not be available
Solution Approach 1:
A second wireless device acts as an intermediary to transfer profile information to the first device. The second device downloads the profile information via OTA and then transfers it to the first device through a direct communication link, eliminating the need for the first device to perform power-intensive OTA operations itself.
Solution Approach 2:
The patent replaces the traditional wireless communication-based OTA update mechanism with a direct communication link (such as NFC or peer-to-peer connection) for profile transfer. This substitution allows the first device to remain in low-power mode while still receiving updates through a different, less energy-intensive communication path.
2Adaptability or versatility
If traditional OTA updates are used to download profile information, then the device can receive updates remotely, but the device requires network coverage which may not be available outside geographic coverage areas
Solution Approach 1:
The second wireless device serves as a mediator that bridges the gap between the network and the first device. It downloads the profile information when network coverage is available and stores it locally, then transfers it to the first device when needed, regardless of the first device's location or network connectivity status.
Solution Approach 2:
The profile information is downloaded and stored in advance by the second device when network conditions are favorable. This preliminary action ensures that the profile update is ready for transfer to the first device at any time, eliminating the constraint of requiring network coverage at the moment of update.
3Duration of action of moving object
If the device enters power saving mode to extend battery life, then battery consumption is reduced, but the device cannot receive OTA updates during this mode
Solution Approach 1:
The second wireless device takes on the role of actively downloading and storing profile information, while the first device remains in power-saving mode. This division of roles allows the first device to maintain its extended battery life while still receiving reliable profile updates through the intermediary.
Solution Approach 2:
The profile information is prepared and stored in advance by the second device before the first device needs it. This preliminary preparation ensures that when the first device is ready to receive the update, the information is already available, maintaining update reliability without requiring the first device to be active during the download process.
