Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map applications do not support users in manually adjusting the map area range for sharing, leading to resource wastage and inefficient sharing of map areas.
Innovation Solution
A method and apparatus that enable dynamic image generation and interactive channel selection for map area sharing, allowing users to adjust and select the map area range interactively, and share it through various channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users take screenshots to share map areas, then sharing functionality is provided, but users cannot manually adjust the shared area and must retake screenshots, causing resource waste
Solution Approach 1:
The patent applies dynamics by transforming the static screenshot sharing into a dynamic adjustable map area sharing. Users can interactively adjust the map area range, zoom level, and position after initiating the sharing operation, without needing to retake screenshots. This dynamic adjustment capability resolves the contradiction by enabling ease of operation while preventing resource waste from retaking screenshots.
Solution Approach 2:
The patent implements preliminary action by pre-generating multiple adjusted map area versions (with different zoom levels and positions) before the user completes the sharing operation. The system prepares these alternative views in advance, allowing users to select and adjust the optimal sharing area without performing resource-intensive screenshot retaking, thus resolving the contradiction between operational ease and resource conservation.
2Loss of information
If users share entire map pages, then complete information is shared, but unnecessary data is transmitted increasing communication overhead
Solution Approach 1:
The patent applies the extraction principle by allowing users to selectively extract and share only the specific map area of interest rather than the entire map page. The adjustable map area functionality enables users to crop out the relevant portion, ensuring complete information about the intended area is shared while eliminating unnecessary data transmission, thus resolving the contradiction between information completeness and communication efficiency.
Solution Approach 2:
The patent implements local quality by enabling different levels of detail and focus on specific map areas. Users can adjust the zoom level and position to highlight important local regions while reducing detail in less important areas, optimizing the balance between information completeness and communication resource consumption.
3Stability of the object's composition
If fixed ratio map areas are generated, then consistent formatting is achieved, but users cannot customize the shared area range
Solution Approach 1:
The patent applies dynamics by making the map area adjustable and flexible rather than fixed. Users can dynamically change the map area range, zoom level, and position according to their needs, while the system maintains format consistency through structured adjustment options. This resolves the contradiction by providing both adaptability for customization and stability for consistent formatting.
Solution Approach 2:
The patent implements parameter changes by allowing users to modify key parameters such as zoom level, position, and area boundaries of the shared map region. The system provides controlled parameter adjustment within a structured framework, enabling customization while maintaining format consistency, thus resolving the contradiction between adaptability and stability.
Data Source
AI summary
A map area sharing method, apparatus, and computer-readable storage medium for sharing map areas through interactive interfaces. The method displays a dynamic image and sharing channel selection box based on a map area sharing operation performed on a target map area. The dynamic image comprises multiple frames, each corresponding to a new map area generated by adjusting the target map area according to a preset ratio. A to-be-shared map area is determined based on an area adjustment operation performed on the target map area. A shared image comprising the to-be-shared map area is generated based on selection of a sharing channel from the selection box. The shared image is then shared to a shared object in the selected sharing channel, enabling efficient map area sharing with dynamic visualization.
