Map Query Reproduction via Historical Record Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map query systems provide inaccurate search results due to historical record-based queries being limited to the current city, failing to accurately reproduce previous search results when the user is in a different location.
Innovation Solution
A map query method that allows users to reproduce previous search results by storing historical records including keywords and map areas, enabling accurate search results even when the user is in a different location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If historical record-based query is used, then query operations are reduced, but search result accuracy deteriorates because the search is limited to the current city
Solution Approach 1:
The system performs preliminary action by storing not only the search keyword but also the map area (city/region) where the search was originally conducted. When a user queries a historical record, the system automatically retrieves and applies the original map area information, so that the search result accuracy is preserved without requiring the user to re-specify the location. This resolves the contradiction by pre-preserving the contextual information needed for accurate search results.
Solution Approach 2:
The system introduces an intermediary mechanism that links historical search records with their corresponding map areas. The historical record structure is enhanced to include a map area field, which acts as a mediator between the search query and the location context. This intermediary storage and retrieval mechanism enables the system to automatically restore the original search context, maintaining accuracy while simplifying user operations.
2Device complexity
If the search is limited to the current city, then the system complexity is reduced, but the search result accuracy deteriorates
Solution Approach 1:
The system performs preliminary action by storing the map area information along with the historical search records. This pre-stored contextual information eliminates the need for complex real-time location detection and user input processing during query reproduction. The system simply retrieves the pre-saved map area from the historical record, maintaining simplicity while achieving accurate search results.
3Measurement precision
If historical records include map area information, then search result accuracy is improved, but the data storage requirement increases
Solution Approach 1:
The system applies local quality by storing map area information only for historical search records that require location context, rather than storing location data for all operations uniformly. The enhancement is applied selectively to the historical record structure where it is most needed for accurate search result reproduction, minimizing unnecessary data storage while maximizing search accuracy where it matters.

AI summary
An electronic device receives a first query request; displays a first interface, where the first interface includes a first search result, and the first search result includes at least one geographical location that is related to the first query request and that is within a map range indicated by a first map area; displays a second interface, where the second interface includes a first historical record, and the first historical record is related to the first query request; receives a second query request that is based on the first historical record; and displays a third interface, where the third interface is the same as the first interface.
