Address List Synchronization Duplicate Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When synchronizing address lists across multiple devices, existing systems often display duplicate information multiple times due to incomplete data consolidation during the synchronization process.
Innovation Solution
An information processing apparatus that acquires and synchronizes address lists, identifying and consolidating duplicate information by comparing data from external and internal lists, and displaying a consolidated address list that eliminates duplicates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If duplicate information is added as they are during synchronization, then the synchronization process is simple and fast, but the information processing apparatus displays duplicate information multiple times
Solution Approach 1:
The information processing apparatus performs preliminary actions by acquiring update histories from external apparatuses before synchronization, and by pre-comparing address information to identify duplicates. This allows the system to prepare consolidation rules and duplicate detection logic in advance, enabling fast synchronization while preventing duplicate displays without sacrificing speed.
Solution Approach 2:
The system implements feedback mechanisms by comparing updated address information with existing address lists during synchronization, identifying duplicate entries, and adjusting the synchronization process accordingly. This feedback loop ensures that duplicate information is detected and consolidated while maintaining efficient synchronization performance.
2Loss of information
If duplicate information is consolidated during synchronization, then duplicate display is prevented, but the synchronization process becomes more complex
Solution Approach 1:
The synchronization process is segmented into distinct phases: acquiring update histories, comparing address information, identifying duplicates, and consolidating results. This segmentation allows the complex duplicate consolidation task to be broken down into manageable steps, reducing the perceived complexity while maintaining effective duplicate prevention.
Solution Approach 2:
The system uses an intermediary approach by introducing update histories as a intermediate data structure that bridges the external address lists and the local address database. This intermediary mechanism simplifies the overall process by providing a standardized way to handle updates and consolidations without directly managing complex merge logic.
3Speed
If address lists are synchronized without consolidation, then the synchronization process is fast, but information accuracy deteriorates due to duplicate displays
Solution Approach 1:
The system performs preliminary comparison and duplicate identification actions during the synchronization process, allowing accurate information consolidation to be achieved without significantly delaying the synchronization speed. By pre-identifying duplicates and preparing consolidation rules in advance, the system maintains both speed and accuracy.
Solution Approach 2:
The patent replaces complex mechanical merging operations with more efficient information comparison and consolidation mechanisms. By using update histories and targeted comparisons rather than full list merges, the system achieves accurate information integration with reduced processing overhead, maintaining synchronization speed while improving accuracy.
