Peripheral Data Caching for Source-Free Wireless Payload Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile computing systems face challenges in efficiently delivering data payloads to target devices when the source device is not readily accessible, such as when a user's mobile device is stored away, making it difficult to present electronic boarding passes or digital keys.
Innovation Solution
A peripheral device, such as a wireless headphone or smartwatch, caches data payloads from a source device via short-range wireless protocols like NFC or Bluetooth, storing them in memory for a limited time and delivering them to the target device when in network proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data payload is stored on source device, then data security is maintained, but data delivery fails when source device is inaccessible
Solution Approach 1:
The patent introduces a peripheral device as an intermediary between the source device and target device. The peripheral device receives and caches the data payload from the source device, then delivers it to the target device when in proximity, enabling data delivery even when the source device is inaccessible.
Solution Approach 2:
The patent implements preliminary action by having the peripheral device cache the data payload in advance before the source device becomes inaccessible. This allows the data to be delivered later without requiring the source device to be present at the time of delivery.
2Reliability
If data payload is cached on peripheral device, then data delivery is enabled when source is inaccessible, but memory resources are consumed
Solution Approach 1:
The patent applies parameter changes by implementing a time-based caching mechanism where the peripheral device stores the data payload only for a limited duration. The cache is automatically cleared after the timeout period expires, thus managing memory resources while enabling data delivery when needed.
3Adaptability or versatility
If peripheral device acts as data agent, then source device accessibility is not required, but device complexity increases
Solution Approach 1:
The patent implements universality by enabling the peripheral device to perform multiple functions: it acts as both a data receiver from the source device and a data transmitter to the target device. This multi-functionality allows the peripheral device to serve as a universal data intermediary without requiring separate dedicated devices.

AI summary
Described are techniques for caching a data payload on a peripheral device for delivery to a target device. The techniques include receiving, at a peripheral device via a short-range wireless protocol, a data payload intended for a target device, where the data payload is received from a source device configured to send the data payload to the target device. The techniques further include storing the data payload in a memory of the peripheral device for a time that allows the peripheral device to be placed in network proximity of the target device and transfer the data payload from the peripheral device to the target device. The techniques further include detecting the target device via a short-range wireless network, and sending the data payload to the target device via a short-range wireless protocol used by the target device.
