Portable Device Theme Switching via Server-Managed Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable communication devices face challenges in processing and storing complex GUI themes due to limited processing performance and storage capacity, often requiring a full application change to switch themes.
Innovation Solution
A theme change system that connects a portable communication device with a server via a communication network, allowing the device to request and store theme data, and output interfaces based on received theme data without changing the process execution part, enabling theme switching without updating the application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If theme data is stored locally in the portable communication device, then theme switching capability is improved, but storage capacity is exceeded and processing burden increases
Solution Approach 1:
The patent moves theme data from local device storage to remote server storage, transitioning from a one-dimensional local storage model to a two-dimensional distributed storage model involving both device and server. This allows the device to access multiple themes without storing them all locally, resolving the contradiction between theme switching capability and storage capacity.
Solution Approach 2:
The patent introduces a server as an intermediary between the portable communication device and theme data. The server acts as a mediator that stores and manages theme data, allowing the device to request and use themes without bearing the full storage burden. This intermediary solution enables theme switching capability while preserving limited device storage capacity.
2Manufacturing precision
If complex GUI themes are processed locally, then interface design quality is improved, but processing performance deteriorates
Solution Approach 1:
The patent segments the theme processing system into two parts: theme data storage and management on the server, and theme rendering and display on the device. This segmentation allows complex GUI themes to be designed and stored with high quality on the server without overwhelming the device's processing capabilities, as the device only needs to retrieve and display pre-processed theme data.
Solution Approach 2:
The server acts as an intermediary that handles the complex processing of GUI theme data before transmission to the device. This allows high-quality interface designs to be processed and optimized on the server side, reducing the processing burden on the device while maintaining design quality.
3Adaptability or versatility
If the whole application is interchanged to change themes, then theme switching is achieved, but device complexity increases
Solution Approach 1:
The patent extracts theme data from the application package and stores it separately on the server. This allows theme switching to occur independently of application changes, as users can request and switch between different theme data sets without needing to interchange entire applications. This extraction reduces device complexity by separating theme management from application management.
Solution Approach 2:
Instead of interchanging entire applications to change themes, the system uses copying of theme data from the server to the device's temporary storage or memory. This allows rapid theme switching by copying only the necessary theme data rather than replacing entire application packages, significantly reducing device complexity and operation time.

AI summary
A theme change system includes a portable communication device; and a server apparatus, wherein the portable communication device and the server apparatus are connected to each other via a communication network. The portable communication device includes a theme request section making a request for theme data related to an interface between a user and a process execution part for performing processing in accordance with a request from the user to the server apparatus, a theme management section determining permission and non-permission about the reception of the theme data requested by the theme request section and storing, in a storage section, the theme data, and an interface output section outputting the interface on the basis of the theme data when the process execution part is started or while the process execution part is being started. The server apparatus includes a transmission section transmitting theme data to the portable communication device.
