Cooperative Download Grid for Mobile Memory Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with limited memory capacity face challenges in downloading large multimedia files, as they often lack sufficient space and time to complete the download without deleting other data, especially in scenarios where multiple devices are present but cannot cooperate for optimized downloading.
Innovation Solution
A method and system that enable multiple devices to form a cooperative download grid by partitioning files based on device properties, establishing communication sessions, and distributing file extents across devices using SIP protocol and local connectivity options like Bluetooth or WiFi, allowing parallel downloading and dynamic aggregation of devices for extended memory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory capacity is extended by using larger memory cards, then storage space is improved, but cost and device complexity increase
Solution Approach 1:
The patent merges multiple mobile devices into a distributed storage system where each device participates in storing different portions of a file. Instead of relying on a single device with large memory capacity, the system combines the storage resources of multiple devices to achieve extended memory capacity, thereby avoiding the need for expensive and complex high-capacity memory cards.
Solution Approach 2:
The patent transitions from a single-device storage model to a multi-device distributed storage model, adding the dimension of network connectivity and device collaboration. This dimensional shift allows the system to overcome the memory capacity limitations of individual devices by leveraging the collective storage resources across multiple devices connected via network.
2Quantity of substance
If memory capacity is extended by using larger memory cards, then storage space is improved, but cost increases
Solution Approach 1:
The system merges the storage capabilities of multiple standard-memory devices to replace the need for expensive high-capacity memory cards. By distributing the storage burden across multiple devices with standard memory, the overall cost is reduced compared to purchasing and implementing large-capacity memory expansion for a single device.
Solution Approach 2:
The patent employs file partitioning and distribution, where copies of file portions are stored across multiple devices. This copying approach allows the system to achieve large storage capacity using multiple standard memory devices rather than relying on expensive high-capacity memory cards, thereby reducing overall system cost.
3Reliability
If single device downloads large multimedia files, then download completeness is ensured, but download time and memory pressure increase
Solution Approach 1:
The patent segments large multimedia files into smaller portions and distributes them across multiple devices for simultaneous download. This segmentation enables parallel downloading operations, significantly reducing the total download time while maintaining completeness through coordinated file assembly at the destination device.
Solution Approach 2:
The system merges multiple concurrent download operations across different devices into a single coordinated file transfer process. By combining the download efforts of multiple devices working in parallel, the system achieves both reduced download time and guaranteed completeness through centralized coordination and file assembly.
4Adaptability or versatility
If multiple devices are available but do not cooperate, then device independence is maintained, but download efficiency is reduced
Solution Approach 1:
The patent implements a dynamic device selection and coordination mechanism that adapts to the available devices and their capabilities. The system dynamically establishes communication sessions, partitions files based on device properties, and coordinates downloads in real-time, thereby achieving high download efficiency while maintaining the flexibility and independence of individual devices.
Solution Approach 2:
The system employs feedback mechanisms to monitor device status, available memory, and connection quality, using this information to dynamically adjust the download distribution strategy. This feedback-driven approach ensures optimal use of available devices while maintaining device independence, achieving high download efficiency through adaptive coordination.

AI summary
An improved download capability for mobile devices, without requiring increasing of the local memory of such devices, by providing a set of multimedia devices with the capability to create a cooperative download grid where multiple instrumented devices can be aggregated together according to predefined profiles. This capability is useful in at least two different scenarios. The first is when a SIP enabled device must download a large file having a capacity that is larger than the available memory of the SIP device. The second is when a SIP enabled device must download a file but cannot be connected for a long enough time to accomplish the download. If the SIP device is in proximity to other compatible devices such as Voice over Internet Protocol (VoIP) or Session Initiation Protocol (SIP), these devices are operable to be dynamically aggregated to provide a download grid with multiprotocol support that allows optimized downloading.
