Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phones and cloud computing environments are unsuitable for efficient mobile cloud computing due to hardware and security limitations, particularly in low-end devices.
Innovation Solution
A mobile cloud system is designed with a cloud server that separates into read-only and read/write file systems, allowing shared and user-specific services, respectively, enabling efficient computing and data processing through a wireless network, reducing hardware requirements in mobile devices and providing high-security, high-performance services even with low-end terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cloud computing services are provided for fixed terminals, then service stability is improved, but mobile adaptability deteriorates
Solution Approach 1:
The patent segments the file system into read-only and read/write portions, allowing the read-only portion to be shared across multiple mobile terminals while the read/write portion provides terminal-specific storage. This segmentation enables cloud services to be efficiently delivered to mobile devices while maintaining service stability through shared resources and providing mobile adaptability through dedicated storage spaces.
2Productivity
If high-end mobile terminals are used, then processing performance is improved, but device cost increases
Solution Approach 1:
The patent extracts heavy processing and storage operations from the mobile terminal and relocates them to the cloud server. The terminal only performs lightweight operations such as displaying images and basic interactions, while the cloud server handles complex processing tasks. This extraction allows low-end terminals to achieve high-end processing performance through cloud connectivity, significantly reducing device cost while maintaining productivity.
3Adaptability or versatility
If more hardware and software are included in mobile devices, then functionality is improved, but device weight increases
Solution Approach 1:
The patent implements a read-only file system portion that is shared across multiple mobile terminals, providing universal access to common applications, services, and data. This multi-functionality approach allows a single cloud-based file system to serve multiple terminals simultaneously, eliminating the need for each device to have duplicate hardware and software, thereby reducing device weight while maintaining full functionality.
4Speed
If data is stored locally on mobile devices, then access speed is improved, but security deteriorates
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the mobile terminal and the data. The terminal communicates with the cloud server through standardized protocols, and the server handles data storage, processing, and security management. This intermediary approach maintains fast access speeds through efficient cloud infrastructure while enhancing security by centralizing data protection measures and eliminating local storage vulnerabilities.
