Dynamic Presentation System Using Master-Local Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current presentation software lacks an efficient method for non-skilled users to create and share personalized dynamic presentations, as existing tools require complex editing and large file transfers, making it difficult to modify or exchange presentations without broadband connections or significant storage.
Innovation Solution
A computer system with a master storage for nodal structures and contents, allowing users to create personalized presentations through a structure editor and contents editor, which generate dynamic presentations by selectively accessing master or personalized content, enabling easy modification and sharing without large file transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If presentation software uses complex editing tools to allow personalization, then customization capability is improved, but ease of operation deteriorates
Solution Approach 1:
The system creates a local copy of the master presentation file in the user's browser, allowing personalization without modifying the original. Users can customize their local copy while the master file remains intact and can be updated by the author.
Solution Approach 2:
The presentation file is segmented into master data (stored centrally) and local personalized data (stored locally in browser). This separation allows independent updates of master content while preserving user personalizations, and enables lightweight local files for easy operation.
2Reliability
If presentation files include all content data to enable standalone viewing, then reliability is improved, but file size increases
Solution Approach 1:
The system extracts only the essential master presentation structure and content from the original file, storing it centrally. The local file contains only minimal references and personalized data, dramatically reducing file size while maintaining viewing capability through connection to the master file.
Solution Approach 2:
The master presentation file serves multiple functions: it is the source for generating local files, the storage for centralized content updates, and the reference for rendering presentations. This multi-functionality eliminates the need for duplicating all content in each local file.
3Adaptability or versatility
If the master presentation file is updated to include new content, then adaptability is improved, but synchronization complexity increases
Solution Approach 1:
The system implements a version tracking mechanism where the master file carries a version identifier. When users open their local files, they check the version and automatically download updates if needed, ensuring synchronization without complex manual processes.
Solution Approach 2:
Users' browsers automatically check for master file updates and download them when needed, without requiring manual intervention or complex synchronization protocols. The system self-manages the update distribution to all local copies.
4Loss of information
If presentation software requires broadband connection for sharing, then content completeness is improved, but ease of operation deteriorates
Solution Approach 1:
The system creates lightweight local copies of presentation files that can be opened and viewed offline in the user's browser. These local files contain sufficient data for viewing and basic personalization, eliminating the need for broadband connections during use or sharing.
Solution Approach 2:
The user's browser acts as an intermediary, caching the master presentation file locally and serving it for offline viewing. This intermediary layer allows users to access and share presentations without direct broadband connection, while the system maintains the ability to update content when connected.
