On-Device Search Module With Remote Updates for Offline Results
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software systems struggle to provide efficient and personalized search and advertisement services on user devices due to reliance on internet connectivity and lack of immediate, relevant results.
Innovation Solution
A local service module on user devices, integrated or standalone, provides search and advertisement functionalities using local data and updates from a remote system, enabling immediate and relevant results without constant internet connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If search and advertisement services rely on remote system connections, then results can be updated frequently, but immediate results cannot be provided without internet connectivity
Solution Approach 1:
The system segments search services into local and remote components. The local service module stores search records, application links, and search functions locally on the user device, enabling immediate local search operations. Simultaneously, a remote service system provides updated search records and functions over the network. This segmentation allows the system to provide immediate results locally while maintaining reliability through remote updates, resolving the contradiction between speed and reliability.
2Adaptability or versatility
If search records and functions are updated remotely, then the system remains current, but device restart is required which interrupts service
Solution Approach 1:
The system implements dynamic update mechanisms where the local service module can be updated without requiring device restart. The module dynamically loads updated search records and search functions from the remote system during operation, allowing the service to remain continuous. This dynamic updating capability enables frequent adaptations while maintaining service productivity and continuity.
3Speed
If all search data is stored locally, then immediate results are provided, but data privacy concerns increase
Solution Approach 1:
The system applies local quality by storing only necessary search records, application links, and search function metadata locally on the user device for immediate processing. Sensitive user data and comprehensive search databases remain on the remote server. This selective local storage enables fast result delivery while minimizing privacy risks by keeping sensitive information centralized on secure remote systems.
Data Source
AI summary
A user device stores a local application including initial search records and an initial search function. Each initial search record includes an application link that opens an application page and search data that describes the application page. The initial search function is configured to select from the initial search records. The user device executes the local application to request and receive search update data from a remote system. The search update data includes updated search records and an updated search function. The user device updates the initial search records and the initial search function with the updated search records and the updated search function. The user device receives a search query from a requesting application, selects a set of updated search records based on the search query and the updated search function, and provides a response to the requesting application including application links from the set of updated search records.
