Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional text-based POI query methods are used, then the system is simple to operate, but the user interaction convenience and query accuracy are insufficient
Solution Approach 1:
The patent replaces traditional text-based query input (mechanical keyboard typing) with image-based visual interaction. Users capture images of POIs using their device camera, and the system automatically processes these images to identify and retrieve relevant POI information, eliminating the need for manual text entry and significantly improving interaction convenience.
Solution Approach 2:
The patent introduces an image processing intermediary layer between the user and the POI database. The system captures images, processes them through object recognition and scene analysis algorithms, extracts relevant POI features, and then queries the database based on these extracted features. This intermediary processing layer enables natural image-based interaction while maintaining system manageability.
2Ease of operation
If image-based POI queries are implemented, then user interaction convenience is improved, but the processing complexity and computational requirements increase
Solution Approach 1:
The patent segments the image processing task into distinct modular components: image acquisition, object recognition, scene environment analysis, POI feature extraction, and database querying. Each module handles a specific aspect of the processing pipeline, making the overall complex system more manageable and maintainable while enabling comprehensive image analysis for accurate POI retrieval.
Solution Approach 2:
The patent performs preliminary processing of images by pre-extracting POI-related features and scene context information before querying the database. The system analyzes images in advance to identify key POI characteristics, stores these extracted features, and then uses them for efficient database matching, reducing the computational burden during actual query operations.
3Measurement precision
If only basic object recognition is used, then the processing speed is fast, but the POI selection accuracy is insufficient
Solution Approach 1:
The patent applies different processing depths to different regions and elements within the image based on their relevance to POI identification. The system performs detailed analysis on key POI-related objects and scene elements while using faster, lighter processing for background or less relevant areas, thereby improving overall accuracy without proportionally increasing processing time for the entire image.
