Wireless Device Caching Data Proxy for Offline Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless portable computers are often powered down or out of network coverage, leading to missed important application packet deliveries from company or network resources, as cellular telephones lack sufficient computing power and configuration to access all necessary applications.
Innovation Solution
A method where a second wireless device acts as a caching proxy for a first wireless device, allowing data communication to be transmitted to and from the second device even when the first device is not connected or powered, using a link between the two devices to receive and transfer data over a wireless network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a wireless portable computer is used as the primary computing device, then computing power and application capability are improved, but availability and continuous access to network resources deteriorate when the device is powered down or out of coverage
Solution Approach 1:
A second wireless device (cellular telephone) acts as an intermediary or proxy to receive and cache data communications when the primary portable computer is unavailable. The second device receives power independently and maintains network connectivity, serving as a mediator that bridges the gap between the network and the primary device, ensuring data availability without requiring the primary device to be constantly powered on.
Solution Approach 2:
The system performs preliminary actions by caching data communications at the second wireless device before the primary device needs them. Data is received, stored, and prepared in advance during periods when the primary device is unavailable, so that when the device becomes available, the data is already cached and ready for immediate transmission without delay.
2Use of energy by moving object
If the primary wireless device is powered down to save battery, then energy consumption is reduced, but data communication and network access are lost
Solution Approach 1:
The second wireless device serves as an intermediary that maintains network connectivity and caches data while the primary device remains powered down. This mediator approach allows the primary device to conserve battery power while ensuring that no data packets are lost, as the second device receives and stores all communications during the period when the primary device is offline.
Solution Approach 2:
Data communications are received and cached in advance at the second device before the primary device needs them. This preliminary action ensures that when the primary device is powered down, all necessary data is already stored and ready for immediate transfer, eliminating any loss of information while maintaining energy efficiency.
3Ease of operation
If cellular telephone features are used for wireless access, then portability and wide area coverage are improved, but computing capability and application configuration are insufficient
Solution Approach 1:
The system combines the strengths of two different wireless devices into a unified multi-functional solution. The cellular telephone provides portability and wide area coverage, while the portable computer provides computing power and application capability. By making these devices work together as a blended system, the solution achieves universality, allowing the team to leverage both portability and computing power without being limited by the weaknesses of either device alone.

AI summary
A wireless device is provided to act as a caching data proxy for a first device, which may or may not be wireless. In particular, a cellular telephone is associated as a caching data proxy for a wireless portable computing device. The cellular telephone caches data as a proxy for the portable computing device when the portable computing device is either out of network coverage, powered down, or the like.
